The HTTPClient component implements client-side functionality of HTTP and HTTPS protocols.

Syntax

TsbxHTTPClient

Remarks

HTTPClient provides means of exchanging HTTP messages with HTTP servers. Both plain (HTTP) and secure (HTTPS) connection types are supported.

Features supported

• All standard request types (GET, POST, PUT etc.), plus custom VERBs
• TLS 1.2 and 1.3 (and earlier versions for older servers)
• Strong client and server authentication on TLS and HTTP levels
• Flexible custom header adjustment
• A variety of proxy server types

Configuring the component

HTTPClient is very easy to configure. In some cases, like in the example given below, you do not need any special tuneups whatsoever: client.Get("http://www.mywebserver.com/"); if (client.StatusCode == 200) { string response = client.OutputString; } You may need to adjust the component settings if you plan to connect to endpoints secured with TLS. By default, HTTPClient relies on the system settings when validating server certificates. If you would prefer to ignore the system trust and implement customized chain validation procedures - such as certificate pinning - in your code instead, set TLSSettings.AutoValidateCertificates to false, and subscribe to CertificateValidate event. This event will fire whenever a server certificate validation needs to be performed.

Use TLSClientChain collection to provide your certificates for client authentication. Make sure the provided certificate contains a private key; otherwise it will be unable to authenticate.

To provide custom HTTP headers, subscribe to HeadersPrepared event. HTTPClient fires this event right before sending the request out to the server, giving you an opportunity to alter the headers or add your own. The list of headers can be accessed via the RequestHeaders collection. Note: the headers can only be modified from the HeadersPrepared event handler. Setting them earlier or later in your code won't provide the expected effect.

Having set up the component, use the appropriate output property (such as OutputFile) to obtain the response in the desired format (string, memory buffer, or file).

Remarks

The ID of the pre-shared key used for DC request authentication.

Asynchronous DCAuth-driven communication requires that parties authenticate each other with a secret pre-shared cryptographic key. This provides an extra protection layer for the protocol and diminishes the risk of the private key becoming abused by foreign parties. Use this property to provide the pre-shared key identifier, and use ExternalCryptoKeySecret to pass the key itself.

The same KeyID/KeySecret pair should be used on the DCAuth side for the signing requests to be accepted.

Note: The KeyID/KeySecret scheme is very similar to the AuthKey scheme used in various Cloud service providers to authenticate users.

Example: signer.ExternalCrypto.KeyID = "MainSigningKey"; signer.ExternalCrypto.KeySecret = "abcdef0123456789";

Data Type

String

};

Default Value

crcAuto

Remarks

Specifies the kind(s) of revocation check to perform.

Revocation checking is necessary to ensure the integrity of the chain and obtain up-to-date certificate validity and trustworthiness information.

This setting controls the way the revocation checks are performed for every certificate in the chain. Typically certificates come with two types of revocation information sources: CRL (certificate revocation lists) and OCSP responders. CRLs are static objects periodically published by the CA at some online location. OCSP responders are active online services maintained by the CA that can provide up-to-date information on certificate statuses in near real time.

There are some conceptual differences between the two. CRLs are normally larger in size. Their use involves some latency because there is normally some delay between the time when a certificate was revoked and the time the subsequent CRL mentioning that is published. The benefits of CRL is that the same object can provide statuses for all certificates issued by a particular CA, and that the whole technology is much simpler than OCSP (and thus is supported by more CAs).

This setting lets you adjust the validation course by including or excluding certain types of revocation sources from the validation process. The crcAnyOCSPOrCRL setting (give preference to the faster OCSP route and only demand one source to succeed) is a good choice for most typical validation environments. The "crcAll*" modes are much stricter, and may be used in scenarios where bulletproof validity information is essential.

Note: If no CRL or OCSP endpoints are provided by the CA, the revocation check will be considered successful. This is because the CA chose not to supply revocation information for its certificates, meaning they are considered irrevocable.

Note: Within each of the above settings, if any retrieved CRL or OCSP response indicates that the certificate has been revoked, the revocation check fails.

This property is not available at design time.

__property int TLSVersions = { read=FTLSVersions, write=FSetTLSVersions };

Default Value

16

Remarks

The SSL/TLS versions to enable by default.

Data Type

Integer

TrustedCertCount Property (HTTPClient Component)

The number of records in the TrustedCert arrays.

Syntax

__property int TrustedCertCount = { read=FTrustedCertCount, write=FSetTrustedCertCount };

Default Value

0

Remarks

This property controls the size of the following arrays:

• TrustedCertBytes
• TrustedCertHandle

The array indices start at 0 and end at TrustedCertCount - 1.

This property is not available at design time.

Data Type

Integer

TrustedCertBytes Property (HTTPClient Component)

Returns the raw certificate data in DER format.

Syntax

__property DynamicArray TrustedCertBytes[int TrustedCertIndex] = { read=FTrustedCertBytes };

Remarks

Returns the raw certificate data in DER format.

The TrustedCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the TrustedCertCount property.

This property is read-only and not available at design time.

Data Type

Byte Array

TrustedCertHandle Property (HTTPClient Component)

Allows to get or set a 'handle', a unique identifier of the underlying property object.

Syntax

__property __int64 TrustedCertHandle[int TrustedCertIndex] = { read=FTrustedCertHandle, write=FSetTrustedCertHandle };

Default Value

0

Remarks

Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.

When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object after such operation. pdfSigner.setSigningCertHandle(certMgr.getCertHandle());

The TrustedCertIndex parameter specifies the index of the item in the array. The size of the array is controlled by the TrustedCertCount property.

This property is not available at design time.

Data Type

Long64

Config Method (HTTPClient Component)

Sets or retrieves a configuration setting.

Syntax

String __fastcall Config(String ConfigurationString);

Remarks

Config is a generic method available in every component. It is used to set and retrieve configuration settings for the component.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

Delete Method (HTTPClient Component)

Sends a DELETE request to the server.

Syntax

void __fastcall Delete(String Url);

Remarks

Use this method to send a DELETE request to server. In response to this request, the server may (without any guarantees) delete the resource specified in Url. Most of the servers disable DELETE requests.

If this request fails, an exception will be thrown, and the error details published in StatusCode and ReasonPhrase properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

DoAction Method (HTTPClient Component)

Performs an additional action.

Syntax

String __fastcall DoAction(String ActionID, String ActionParams);

Remarks

DoAction is a generic method available in every component. It is used to perform an additional action introduced after the product major release. The list of actions is not fixed, and may be flexibly extended over time.

The unique identifier (case insensitive) of the action is provided in the ActionID parameter.

ActionParams contains the value of a single parameter, or a list of multiple parameters for the action in the form of PARAM1=VALUE1;PARAM2=VALUE2;....

Common ActionIDs:

Get Method (HTTPClient Component)

Sends a GET request to the server.

Syntax

void __fastcall Get(String Url);

Remarks

GET is one of the most widely used HTTP requests. The server responds with the content of the resource specified in Url.

If the request is successful, the received content will be available in OutputBytes and OutputString properties. Otherwise an exception will be thrown, and the error details published in StatusCode and ReasonPhrase properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

Head Method (HTTPClient Component)

Sends a HEAD request to the server.

Syntax

void __fastcall Head(String Url);

Remarks

HEAD is very similar to GET, with the only difference being that only the headers (but not the content) is returned.

HEAD is often use to retrieve the parameters of the resource, such as its size and modification date. If the request is successful, those details will be available via ResponseParameters and ResponseHeaders properties. Otherwise, an exception will be thrown, and the error details published in StatusCode and ReasonPhrase properties.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

Options Method (HTTPClient Component)

Sends an OPTIONS request to the server.

Syntax

void __fastcall Options(String Url);

Remarks

This request gets various information about the server such as supported HTTP methods. No content is included in the response.

Post Method (HTTPClient Component)

Sends a POST request to the server.

Syntax

void __fastcall Post(String Url, String Content);

Remarks

POST is used to send data to the remote HTTP endpoint/script.

Provide the data you need to send via the Content parameter. If Content is omitted, and only Url is set, the data will be streamed dynamically using the DynamicDataNeeded event.

To post a web form's data (including file attachments to the form) use PostWebForm method.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

PostBytes Method (HTTPClient Component)

Sends a POST request to the server.

Syntax

void __fastcall PostBytes(String Url, DynamicArray<Byte> ContentBytes);

Remarks

POST is used to send data to the remote HTTP endpoint/script.

Syntax

void __fastcall PostFile(String Url, String FileName);

Remarks

POST is used to send data to the remote HTTP endpoint/script. The content to send will be taken from FileName.

To post a web form's data (including file attachments to the form) use PostWebForm method.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

PostWebForm Method (HTTPClient Component)

Posts a web form data to the server.

Syntax

void __fastcall PostWebForm(String Url, String Fields, String FileField, String FileName, String ContentType);

Remarks

This variant of the POST method provides means to submit a form (as in a web browser) with an optional file attachment. Fields are expected to contain a list of field names and values in "Name=Value" format separated with EOLs. This list can be empty.

If including a file with your request, use the FileField and FileName properties to specify the file field name and the local filename for the uploaded file. Use ContentType to override the default content type chosen by the client, e.g., "application/x-www-form-urlencoded".

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

Put Method (HTTPClient Component)

Sends a PUT request to the server.

Syntax

void __fastcall Put(String Url, String Content);

Remarks

PUT method is used to write data to the server. This method is optional to support and is disabled on most of HTTP servers.

If Content is not present, and only Url is set, the data will be streamed dynamically using the DynamicDataNeeded event. Note that some servers do not support streaming.

Note that any parameters you intend to pass to this method should be properly encoded before this method is called.

PutBytes Method (HTTPClient Component)

Sends a PUT request to the server.

Syntax

void __fastcall PutBytes(String Url, DynamicArray<Byte> ContentBytes);

DynamicDataNeeded Event (HTTPClient Component)

Requests a portion of data to be uploaded from the application.

Syntax

typedef struct {
  int BytesNeeded;
} TsbxHTTPClientDynamicDataNeededEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientDynamicDataNeededEvent)(System::TObject* Sender, TsbxHTTPClientDynamicDataNeededEventParams *e);
__property TsbxHTTPClientDynamicDataNeededEvent OnDynamicDataNeeded = { read=FOnDynamicDataNeeded, write=FOnDynamicDataNeeded };

Remarks

If dynamic ('streaming') variants of PUT or POST methods are used, this event is fired periodically to request portions of data to be sent to the server.

When handling this event, assign the next portion of data of BytesNeeded length (or less) to DynamicData. If no more data is available to upload (the whole document has been sent), leave DynamicData empty.

Error Event (HTTPClient Component)

Information about errors during data delivery.

Syntax

typedef struct {
  int ErrorCode;
  String Description;
} TsbxHTTPClientErrorEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientErrorEvent)(System::TObject* Sender, TsbxHTTPClientErrorEventParams *e);
__property TsbxHTTPClientErrorEvent OnError = { read=FOnError, write=FOnError };

Remarks

The event is fired in case of exceptional conditions during message processing.

ErrorCode contains an error code and Description contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the HTTPS section.

ExternalSign Event (HTTPClient Component)

Handles remote or external signing initiated by the SignExternal method or other source.

Syntax

typedef struct {
  String OperationId;
  String HashAlgorithm;
  String Pars;
  String Data;
  String SignedData;
} TsbxHTTPClientExternalSignEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientExternalSignEvent)(System::TObject* Sender, TsbxHTTPClientExternalSignEventParams *e);
__property TsbxHTTPClientExternalSignEvent OnExternalSign = { read=FOnExternalSign, write=FOnExternalSign };

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the component via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };

__property TsbxHTTPClientNotificationEvent OnNotification = { read=FOnNotification, write=FOnNotification };

Remarks

The component fires this event to let the application know about some event, occurrence, or milestone in the component. For example, it may fire to report completion of the document processing. The list of events being reported is not fixed, and may be flexibly extended over time.

The unique identifier of the event is provided in the EventID parameter. EventParam contains any parameters accompanying the occurrence. Depending on the type of the component, the exact action it is performing, or the document being processed, one or both may be omitted.

This component can fire this event with the following EventID values:

Progress Event (HTTPClient Component)

Fires periodically during the data transfer.

Syntax

typedef struct {
  __int64 Total;
  __int64 Current;
  bool Cancel;
} TsbxHTTPClientProgressEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientProgressEvent)(System::TObject* Sender, TsbxHTTPClientProgressEventParams *e);
__property TsbxHTTPClientProgressEvent OnProgress = { read=FOnProgress, write=FOnProgress };

Remarks

Use this event to check the progress of an upload or download operation. Total indicates the total number of bytes to be transferred; Current specifies how much data has been transferred so far, and Cancel gives you a chance to cancel the operation.

Redirection Event (HTTPClient Component)

Fires when the server suggests a redirect.

Syntax

typedef struct {
  String OldURL;
  String NewURL;
  bool AllowRedirection;
} TsbxHTTPClientRedirectionEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientRedirectionEvent)(System::TObject* Sender, TsbxHTTPClientRedirectionEventParams *e);
__property TsbxHTTPClientRedirectionEvent OnRedirection = { read=FOnRedirection, write=FOnRedirection };

Remarks

Generally, this is a notification event: the component handles redirections automatically. Use the MaxRedirections config property to limit the number of redirection hops.

TLSCertNeeded Event (HTTPClient Component)

Fires when a remote TLS party requests a client certificate.

Syntax

typedef struct {
  String Host;
  String CANames;
} TsbxHTTPClientTLSCertNeededEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientTLSCertNeededEvent)(System::TObject* Sender, TsbxHTTPClientTLSCertNeededEventParams *e);
__property TsbxHTTPClientTLSCertNeededEvent OnTLSCertNeeded = { read=FOnTLSCertNeeded, write=FOnTLSCertNeeded };

Remarks

This event fires to notify the implementation that a remote TLS server has requested a client certificate. The Host parameter identifies the host that makes a request, and the CANames parameter (optional, according to the TLS spec) advises on the accepted issuing CAs.

Use the TLSClientChain property in response to this event to provide the requested certificate. Please make sure the client certificate includes the associated private key. Note that you may set the certificates before the connection without waiting for this event to fire.

This event is preceded by the TLSHandshake event for the given host and, if the certificate was accepted, succeeded by the TLSEstablished event.

TLSCertValidate Event (HTTPClient Component)

This event is fired upon receipt of the TLS server's certificate, allowing the user to control its acceptance.

Syntax

typedef struct {
  String ServerHost;
  String ServerIP;
  bool Accept;
} TsbxHTTPClientTLSCertValidateEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientTLSCertValidateEvent)(System::TObject* Sender, TsbxHTTPClientTLSCertValidateEventParams *e);
__property TsbxHTTPClientTLSCertValidateEvent OnTLSCertValidate = { read=FOnTLSCertValidate, write=FOnTLSCertValidate };

Remarks

This event is fired during a TLS handshake. Use the TLSServerChain property to access the certificate chain. In general, components may contact a number of TLS endpoints during their work, depending on their configuration.

Accept is assigned in accordance with the outcome of the internal validation check performed by the component, and can be adjusted if needed.

TLSEstablished Event (HTTPClient Component)

Fires when a TLS handshake with Host successfully completes.

Syntax

typedef struct {
  String Host;
  String Version;
  String Ciphersuite;
  DynamicArray ConnectionId;
  bool Abort;
} TsbxHTTPClientTLSEstablishedEventParams;

__property TsbxHTTPClientTLSEstablishedEvent OnTLSEstablished = { read=FOnTLSEstablished, write=FOnTLSEstablished };

Remarks

The component uses this event to notify the application about a successful completion of a TLS handshake.

The Version, Ciphersuite, and ConnectionId parameters indicate the security parameters of the new connection. Use the Abort parameter if you need to terminate the connection at this stage.

TLSHandshake Event (HTTPClient Component)

Fires when a new TLS handshake is initiated, before the handshake commences.

Syntax

typedef struct {
  String Host;
  bool Abort;
} TsbxHTTPClientTLSHandshakeEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientTLSHandshakeEvent)(System::TObject* Sender, TsbxHTTPClientTLSHandshakeEventParams *e);
__property TsbxHTTPClientTLSHandshakeEvent OnTLSHandshake = { read=FOnTLSHandshake, write=FOnTLSHandshake };

Remarks

The component uses this event to notify the application about the start of a new TLS handshake to Host. If the handshake is successful, this event will be followed by the TLSEstablished event. If the server chooses to request a client certificate, the TLSCertNeeded event will also be fired.

TLSPSK Event (HTTPClient Component)

Notifies the application about the PSK key exchange.

Syntax

typedef struct {
  String Host;
  String Hint;
} TsbxHTTPClientTLSPSKEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientTLSPSKEvent)(System::TObject* Sender, TsbxHTTPClientTLSPSKEventParams *e);
__property TsbxHTTPClientTLSPSKEvent OnTLSPSK = { read=FOnTLSPSK, write=FOnTLSPSK };

Remarks

The component fires this event to notify the application about the beginning of TLS-PSK key exchange with Host. The Hint parameter may be used by the server to identify the key or service to use. Use the PreSharedKey field of TLSSettings to provide the pre-shared key to the component.

TLSShutdown Event (HTTPClient Component)

Reports the graceful closure of a TLS connection.

Syntax

typedef struct {
  String Host;
} TsbxHTTPClientTLSShutdownEventParams;
typedef void __fastcall (__closure *TsbxHTTPClientTLSShutdownEvent)(System::TObject* Sender, TsbxHTTPClientTLSShutdownEventParams *e);
__property TsbxHTTPClientTLSShutdownEvent OnTLSShutdown = { read=FOnTLSShutdown, write=FOnTLSShutdown };

Remarks

This event notifies the application about the closure of an earlier established TLS connection. Note that only graceful connection closures are reported.

Config Settings (HTTPClient Component)

The component accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the component, access to these internal properties is provided through the Config method.

HTTPClient Config Settings

Base Config Settings

Trappable Errors (HTTPClient Component)
