The REST Control can be used to retrieve XML documents from the World Wide Web.

Syntax

REST

Remarks

The REST Control supports both plaintext and Secure Sockets Layer/Transport Layer Security (SSL/TLS) connections. When connecting over Secure Sockets Layer/Transport Layer Security (SSL/TLS) the SSLServerAuthentication event allows you to check the server identity and other security attributes. The SSLStatus event provides information about the SSL handshake. Additional SSL-related settings are also supported through the Config method.

The REST Control implements a standard REST client with the added option of SSL security.

The control contains a number of properties that map directly to HTTP request headers. All XML data received are parsed by the component and are provided to the user through properties, such as XPath, XElement, and XText, which allow for traversal of the document structure. The Header event will provide the HTTP headers as returned by the server.

To receive a document, call the Get method with the URL to retrieve the specified resource in the URL parameter. The control will automatically parse the XML data, depending on the content type that is returned. Call the Delete method to delete a resource specified by the URL parameter.

The Post and Put methods are used to create and update resources. Post is commonly used to both create and update resources; however, each service may have its own requirements. To send data to the server, set PostData and call the Post or Put method.

To add authorization credentials to an outgoing request, you should specify the User and Password properties. The REST Control supports basic, digest, and NTLM authentication through the AuthScheme property.

Accept Property (REST Control)

This property includes a list of acceptable MIME types for the request.

Syntax

restcontrol.Accept[=string]

Default Value

""

Remarks

If this property contains a nonempty string, an HTTP Accept header is added to the request.

The Accept header is used for content negotiation. It provides the server with a comma-separated list of MIME types that are acceptable for its response.

Data Type

String

Authorization Property (REST Control)

This property includes the Authorization string to be sent to the server.

Syntax

restcontrol.Authorization[=string]

Default Value

""

Remarks

If the Authorization property contains a nonempty string, an Authorization HTTP request header is added to the request. This header conveys Authorization information to the server.

A common use for this property is to specify OAuth authorization string.

This property is provided so that the HTTP control can be extended with other security schemes in addition to the authorization schemes already implemented by the control.

The AuthScheme property defines the authentication scheme used. In the case of HTTP Basic Authentication (default), every time User and Password are set, they are Base64 encoded, and the result is put in the Authorization property in the form "Basic [encoded-user-password]".

Data Type

String

AuthScheme Property (REST Control)

This property specifies the authentication scheme to use when server authentication is required.

Syntax

restcontrol.AuthScheme[=integer]

Possible Values

authBasic(0), 
authDigest(1), 
authProprietary(2), 
authNone(3), 
authNtlm(4), 
authNegotiate(5), 
authOAuth(6)

Default Value

0

Remarks

This property will tell the control which type of authorization to perform when the User and Password properties are set.

This property should be set to authNone (3) when no authentication is to be performed.

By default, this property is authBasic (0), and if the User and Password properties are set, the control will attempt HTTP Basic Authentication. If AuthScheme is set to authDigest (1), authNtlm (4), or authNegotiate (5), then Digest, NTLM, or Windows Negotiate (Kerberos) authentication will be attempted instead.

If AuthScheme is set to authProprietary (2), then the authorization token must be supplied through the Authorization property.

If AuthScheme is set to authOAuth (6), then the authorization string must be supplied through the Authorization property.

Note: If you set the Authorization property and AuthScheme is not authProprietary or authOAuth, then the AuthScheme will be set automatically to authProprietary (2) by the control.

For security, changing the value of this property will cause the control to clear the values of User, Password, and Authorization.

Data Type

Integer

BuildDOM Property (REST Control)

When set to True, this property creates an internal object model of the XML document.

restcontrol.FollowRedirects[=integer]

Possible Values

frNever(0), 
frAlways(1), 
frSameScheme(2)

Default Value

0

Remarks

This property determines what happens when the server issues a redirect. Normally, the control returns an error if the server responds with an "Object Moved" message. If this property is set to frAlways (1), the new URL for the object is retrieved automatically every time.

If this property is set to frSameScheme (2), the new URL is retrieved automatically only if the URLScheme is the same; otherwise, the control fails with an error.

Note: Following the HTTP specification, unless this property is set to frAlways (1), automatic redirects will be performed only for GET or HEAD requests. Other methods potentially could change the conditions of the initial request and create security vulnerabilities.

Furthermore, if either the new URL server or port are different from the existing one, User and Password are also reset to empty. If, however, this property is set to frAlways (1), the same credentials are used to connect to the new server.

A Redirect event is fired for every URL the product is redirected to. In the case of automatic redirections, the Redirect event is a good place to set properties related to the new connection (e.g., new authentication parameters).

The default value is frNever (0). In this case, redirects are never followed, and the control fails with an error instead.

This property includes a date determining the maximum age of the desired document.

Syntax

restcontrol.IfModifiedSince[=string]

Default Value

""

Remarks

If this property contains a nonempty string, an If-Modified-Since HTTP header is added to the request. The value of this header is used to make the HTTP request conditional: If the requested documented has not been modified since the time specified in the field, a copy of the document will not be returned from the server; instead, a 304 (not modified) response will be returned by the server and the control fails with an error

The format of the date value for IfModifiedSince is detailed in the HTTP specs. An example is Sat, 29 Oct 1994 19:43:31 GMT.

Syntax

restcontrol.LocalHost[=string]

Default Value

""

Remarks

This property contains the name of the local host as obtained by the gethostname() system call, or if the user has assigned an IP address, the value of that address.

In multihomed hosts (machines with more than one IP interface) setting LocalHost to the IP address of an interface will make the control initiate connections (or accept in the case of server controls) only through that interface. It is recommended to provide an IP address rather than a hostname when setting this property to ensure the desired interface is used.

If the control is connected, the LocalHost property shows the IP address of the interface through which the connection is made in internet dotted format (aaa.bbb.ccc.ddd). In most cases, this is the address of the local host, except for multihomed hosts (machines with more than one IP interface).

Note: LocalHost is not persistent. You must always set it in code, and never in the property window.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

Meta Event (REST Control)

This event fires when a meta section is encountered.

Syntax

Sub restcontrol_Meta(Text As String)

Remarks

The Meta event is fired whenever a meta information section (<! ..text... >) is found in the document.

The full text of the meta section is provided by the Text parameter.

PI Event (REST Control)

This event is fired when a processing instruction section is encountered.

Syntax

Sub restcontrol_PI(Text As String)

Remarks

The PI event is fired whenever a processing instruction section (<? ..text... ?>) is found in the document.

The full text of the processing instruction is provided by the Text parameter.

Redirect Event (REST Control)

Fired when a redirection is received from the server.

Syntax

Sub restcontrol_Redirect(Location As String, Accept As Boolean)

Remarks

This event is fired in cases in which the client can decide whether or not to continue with the redirection process. The Accept parameter is always True by default, but if you do not want to follow the redirection, Accept may be set to False, in which case the control fails with an error. Location is the location to which the client is being redirected. Further control over redirection is provided in the FollowRedirects property.

SetCookie Event (REST Control)

Fired for every cookie set by the server.

Syntax

Sub restcontrol_SetCookie(Name As String, Value As String, Expires As String, Domain As String, Path As String, Secure As Boolean)

Remarks

This event is fired for every Set-Cookie: header received from the HTTP server.

The Name parameter contains the name of the cookie, with the corresponding value supplied in the Value parameter.

The Expires parameter contains an expiration time for the cookie (if provided by the server). The time format used is "Weekday, DD-Mon-YY HH:MM:SS GMT". If the server does not provide an expiration time, the Expires parameter will be an empty string. In this case, the convention is to drop the cookie at the end of the session.

The Domain parameter contains a domain name to limit the cookie to (if provided by the server). If the server does not provide a domain name, the Domain parameter will be an empty string. The convention in this case is to use the server specified in the URL (URLServer) as the cookie domain.

The Path parameter contains a path name to limit the cookie to (if provided by the server). If the server does not provide a cookie path, the Path parameter will be an empty string. The convention in this case is to use the path specified in the URL (URLPath) as the cookie path.

The Secure parameter specifies whether the cookie is secure. If the value of this parameter is True, the cookie value must be submitted only through a secure (HTTPS) connection.

SpecialSection Event (REST Control)

This event is fired when a special section is encountered.

Syntax

Sub restcontrol_SpecialSection(SectionId As String, Text As String)

Remarks

The SpecialSection event is fired whenever a special section (such as <![ CDATA [ ..text... ]]>) is found in the document.

The full text of the special section is provided by the Text parameter, and the SectionId parameter provides the section identifier (e.g., CDATA).

SSLServerAuthentication Event (REST Control)

Fired after the server presents its certificate to the client.

Syntax

Sub restcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (REST Control)

Fired when secure connection progress messages are available.

Syntax

Sub restcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartElement Event (REST Control)

This event is fired when a begin-element tag is encountered in the document.

Syntax

Sub restcontrol_StartElement(Namespace As String, Element As String, QName As String, IsEmpty As Boolean)

Remarks

The StartElement event is fired when a begin-element tag is found in the document.

The element name is provided through the Element parameter. The attribute names and values (if any) are provided through the AttrName, AttrNamespace, AttrPrefix, and AttrValue properties.

The IsEmpty parameter is True when the event corresponds to an empty element declaration.

StartPrefixMapping Event (REST Control)

This event is fired when entering the scope of a namespace declaration.

Syntax

Sub restcontrol_StartPrefixMapping(Prefix As String, URI As String)

Remarks

The EndPrefixMapping event is fired when leaving the scope of a namespace declaration.

StartTransfer Event (REST Control)

Fired when a document starts transferring (after the headers).

Syntax

Sub restcontrol_StartTransfer(Direction As Integer)

Remarks

This event is fired first when the client starts sending data to the server (in a POST or PUT request) and then when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Status Event (REST Control)

Fired when the HTTP status line is received from the server.

Syntax

Sub restcontrol_Status(HTTPVersion As String, StatusCode As Integer, Description As String)

Remarks

HTTPVersion is a string containing the HTTP version string as returned from the server (e.g., "1.1").

StatusCode contains the HTTP status code (e.g., 200), and Description the associated message returned by the server (e.g., "OK").

Transfer Event (REST Control)

Fired while a document transfers (delivers document).

Syntax

Sub restcontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.
