The AS4Server component implements an AS4 / ebHandler.

Syntax

nsoftware.IPWorksEDI.As4server

Remarks

The AS4Server class implements server-side processing of AS4 messages. It may be used to receive files form a client (push), respond to a client's request for files (pull), and also handles generating and verifying receipts.

The class is designed to be easily integrated into a HTTP server, such as ASP.NET, but may also be used outside of a web server. The examples below assume the class is used within an environment where there is an HTTP context.

To begin, when a request is received first call ReadRequest. This reads the AS4 request from the . Alternatively the request data may be passed directly to the class by specifying calling SetRequestStream. After calling ReadRequest the following properties may be checked:

The first step after calling ReadRequest is to determine if the client is sending files (push) or requesting files (pull). To determine this check the value of AgreementRef and MPC. For instance:

if (server.AgreementRef == "" && server.MPC != "")
{
  //The client is requesting files from the specified MPC
  //No other relevant properties are populated
}
else //AgreementRef is not empty, and MPC is empty
{
  //The client is sending files. AgreementRef is populated with the agreement reference.
  //AS4From, AS4To, ConversationId, etc are populated
}

Determining if the request contains an asynchronous receipt from a previous transmission may also be done at this time by checking the IncomingReceipt property's Content property. If it is populated a receipt is present. To verify the receipt set AsyncReceiptInfoDir to the directory where information about the message was originally stored and call VerifyReceipt. If the receipt is signed SignerCert must also be set. See the section below and also SendFiles for more details.

Once information about the request is determined the class may then be configured to respond appropriately depending on the operation.

Receiving Files and Sending a Receipt

When receiving files first check the AgreementRef, AS4From, and AS4To properties to determine who is sending the files and with what previously agreed upon configuration. Once this is known, if the request is signed and encrypted set Certificate to the decryption certificate and SignerCert to the public certificate used for signature verification. IncomingDirectory may optionally be set to automatically store the incoming files.

//Process incoming files and send a signed receipt

server.ReadRequest();

//Inspect values from the request in order to load appropriate certificates etc.
//Console.WriteLine(server.AgreementRef);
//Console.WriteLine(server.AS4From.Id);
//Console.WriteLine(server.AS4To.Id);)

server.IncomingDirectory = "..\\MyFiles";
 
//Our private certificate. Used to decrypt the incoming file
server.Certificate = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*");

//Partner's public certificate. Used to verify the signature on the incoming message and files.
server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer"));

server.ParseRequest();

server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmSync;

//Our private certificate. Used to sign the receipt.
server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*");

server.SendResponse(); //Sends the receipt
Receiving Files and Sending an Asynchronous Receipt

Receipts may be sent in the response (synchronous) or at a later time (asynchronous). If the agreement specifies that the receipt be sent asynchronously the following steps may be taken to send the receipt.

After calling ReadRequest the ReceiptReplyMode may be set to indicate the receipt will be returned asynchronously. After calling ParseRequest call SendAckResponse to send back a HTTP 200 OK to the client. The receipt may then be returned later.

To send an asynchronous receipt AS4Client may be used. This can be sent to the partner's web site, or bundled with a later response (depending on the agreement made between the parties). In the example below AS4Client is used to send the receipt to the other party's web site.


//Process incoming files and send an asynchronous receipt

server.ReadRequest();

//Inspect values from the request in order to load appropriate certificates etc.
//Console.WriteLine(server.AgreementRef);
//Console.WriteLine(server.AS4From.Id);
//Console.WriteLine(server.AS4To.Id);)

server.IncomingDirectory = "..\\MyFiles";
 
//Our private certificate. Used to decrypt the incoming file
server.Certificate = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*");

//Partner's public certificate. Used to verify the signature on the incoming message and files.
server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer"));

server.ParseRequest();

server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmAsync;

//Our private certificate. Used to sign the receipt.
server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*");

server.SendAckResponse(); //Sends an ack, but not the receipt
At this point Receipt is populated with the receipt to be sent. Store the Receipt's Content and RefToMessageId values for use when sending the receipt later. Sending a receipt can be done with AS4Client.


//Send an asynchronous receipt
client.URL = ""http://www.company.com:9090/msh"";
client.Receipt = new EBReceipt(server.Receipt.RefToMessageId, server.Receipt.Content);
client.ReceiptReplyMode = As4clientReceiptReplyModes.rrmAsync;
client.SendReceipt();

Sending Files

To process a request to send files first check the MPC property. This holds the Message Partition Channel (MPC) from which the client would like to receive files. Next, set AgreementRef, AS4From, AS4To. Check IncomingReceipt to determine if the request has a bundled receipt. If it does VerifyReceipt can be called to verify the receipt.

Note: If the client requests files from the default MPC then MPC may be empty. See MessageType for details.

If the client makes use of UsernameToken authentication the TokenAuthentication event will fire when processing the request.

To send files back to the client simply set EDIData to the files you wish to send. When SendResponse is called the files will be sent back to the client.


//Process a request to send files (pull)

//Holds information from the original send so that receipts can be verified later
server.AsyncReceiptInfoDir = Path.Combine(Request.PhysicalApplicationPath, "..\\temp\\ReceiptInfoDir")

server.Profile = As4serverProfiles.ebpfENTSOG;
server.ReadRequest();

//The receipt may be signed depending upon the AgreementRef
server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer"));

//If the request has a bundled receipt verify it first
if (!string.IsNullOrEmpty(server.IncomingReceipt.Content))
{
  server.VerifyReceipt();
}

//If the request is a pull request (MPC is set)
if (server.AgreementRef == "" && server.MPC != "")
{
  server.AgreementRef = "http://agreements.company.com/pull_files";
  server.AS4From.Id = "org:holodeckb2b:example:company:B";
  server.AS4From.Role = "Sender";

  server.AS4To.Id = "org:holodeckb2b:example:company:A";
  server.AS4To.Role = "Receiver";

  server.ReceiptReplyMode = As4serverReceiptReplyModes.rrmAsync;

  //Our private certificate. Used to sign the message and files.
  server.SigningCert = new Certificate(CertStoreTypes.cstPFXFile, Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyB.pfx"), "password", "*");

  //Partner's public certificate. Used to encrypt files. 
  server.RecipientCerts.Add(new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer")));

  EBData data = new EBData();
  data.EDIType = "text/xml";
  data.Data = "<test>Hello AS4 World!</test>";
  server.EDIData.Add(data);

  server.SendResponse();
}

Processing Receipts

Any incoming request may potentially include a receipt. The request may be a receipt by itself, or it may be bundled with another type of request (send/receive). When initially sending files AsyncReceiptInfoDir may be set to store data about the original message on disk for use when verifying the receipt. If this is not desired manually store the OriginalSOAPMessage and OriginalSOAPMessageId instead.

To detect if an incoming request contains a receipt simply check the IncomingReceipt property's Content property. If it is populated the request includes a receipt. Set AsyncReceiptInfoDir to the same location as when the file was originally sent. Or alternatively set OriginalSOAPMessage and OriginalSOAPMessageId properties to the original values.

If the receipt is signed set SignerCert to the public certificate which will be used to verify the signature. Lastly call VerifyReceipt. This will perform any signature verification and verify the receipt content as well, matching it to the original message values.


server.ReadRequest();

//The receipt may be signed depending upon the AgreementRef
server.SignerCert = new Certificate(Path.Combine(Request.PhysicalApplicationPath, "..\\files\\CompanyA.cer"));

//If the request contains a receipt verify it
if (!string.IsNullOrEmpty(server.IncomingReceipt.Content))
{
  server.VerifyReceipt();
}
