java - Jain-Sip 身份验证

Question

我正在使用 Jain Sip 库，试图创建到星号服务器的连接。我一直在使用此页面中的 textclient 示例应用程序: http://www.oracle.com/technetwork/articles/entarch/introduction-jain-sip-090386.html

但这实际上并没有向服务器进行身份验证。我可以向服务器上的用户发送消息，但我通常需要在服务器上进行用户/密码身份验证。

据我所知，我必须使用“javax.sip.OUTBOUND_PROXY”属性，但我找不到任何关于如何设置用户名或密码的文档。有没有其他人在这方面取得过任何成功？

我在注册时找到的最好的例子是here .这是万一有一天链接干涸的要点:

REGISTER request is used to update the current location of a user on the REGISTRAR server. The application sends a REGISTER message informing the server its current location which in turn is stored in location server. When a caller calls a user the proxy server uses this information to find the location of the callee.

Register request should be sent by the client periodically. The validity of the REGISTER request is determined by the Expires header.

Flow

Sample Request

REGISTER sip:sip.linphone.org SIP/2.0
Call-ID: 0a0f14355fa76ae6435b98bfe085baf9@223.1.1.128
CSeq: 1 REGISTER
From: <sip:vkslabs@sip.linphone.org>;tag=-1427592833
To: <sip:vkslabs@sip.linphone.org>
Max-Forwards: 70
Via: SIP/2.0/TCP 223.1.1.128:5060;branch=z9hG4bK-323532-2a454f4ec2a4213f6d6928eba479521d
Contact: <sip:vkslabs@223.1.1.128;transport=tcp>
Content-Length: 0

Now lets see how to construct the above request using the NIST SIP Stack.

First step is to create a class that implements the SIPListener. Make sure your SIP Stack is Initializing NIST JAIN SIP Stack.

1. Create Call-ID header

   CallIdHeader callIdHeader = this.sipProvider.getNewCallId();

2. Create CSeq header

   CSeqHeader cSeqHeader = this.headerFactory.createCSeqHeader(cseq, "REGISTER");

3. Create From header

   Address fromAddress = addressFactory.createAddress("sip:" + username + '@' + server); FromHeader fromHeader = this.headerFactory.createFromHeader(fromAddress, String.valueOf(this.tag));

4. Create To Header

   ToHeader toHeader = this.headerFactory.createToHeader(fromAddress, null);

5. Create Max-Forwards header

   MaxForwardsHeader maxForwardsHeader = this.headerFactory.createMaxForwardsHeader(70);

6. Create a Via header

   ArrayList viaHeaders = new ArrayList(); ViaHeader viaHeader = this.headerFactory.createViaHeader(this.ip, this.port, "tcp", null); viaHeaders.add(viaHeader);

7. Create contact header

   this.contactAddress = this.addressFactory.createAddress("sip:" + this.username + '@' + this.ip + "transport=tcp");

   // Create the contact header used for all SIP messages. this.contactHeader = this.headerFactory.createContactHeader(contactAddress);

Once all the headers are created it is time to create the request itself.

request = this.messageFactory.createRequest("REGISTER sip:" + server + "SIP/2.0\r\n\r\n"); 
request.addHeader(callIdHeader);
request.addHeader(cSeqHeader); 
request.addHeader(fromHeader);
request.addHeader(toHeader); 
request.addHeader(maxForwardsHeader);
request.addHeader(viaHeader); 
request.addHeader(contactHeader);

Now that the request object is created with all the necessary headers it is time to send the request.

inviteTid = sipProvider.getNewClientTransaction(request); // send the request out. 
inviteTid.sendRequest();

Once the request is sent successfully the response will be passed to the application using the processResponse callback in SIPListener.

public void processResponse(ResponseEvent responseEvent) { 
  int statusCode = responseEvent.getResponse().getStatusCode(); 
}

Code

public void register(Response response) {
  try {
  cseq++;
  ArrayList viaHeaders = new ArrayList();
  ViaHeader viaHeader = this.headerFactory.createViaHeader(this.ip,
  this.port, "tcp", null);
  viaHeaders.add(viaHeader);
  // The "Max-Forwards" header.
  MaxForwardsHeader maxForwardsHeader = this.headerFactory
  .createMaxForwardsHeader(70);
  // The "Call-Id" header.
  CallIdHeader callIdHeader = this.sipProvider.getNewCallId();
  // The "CSeq" header.
  CSeqHeader cSeqHeader = this.headerFactory.createCSeqHeader(cseq,
  "REGISTER");

  Address fromAddress = addressFactory.createAddress("sip:"
  + username + '@' + server);

  FromHeader fromHeader = this.headerFactory.createFromHeader(
  fromAddress, String.valueOf(this.tag));
  // The "To" header.
  ToHeader toHeader = this.headerFactory.createToHeader(fromAddress,
  null);

  // this.contactHeader = this.headerFactory
  // .createContactHeader(contactAddress);

  request = this.messageFactory.createRequest("REGISTER sip:"
  + server + " SIP/2.0\r\n\r\n");
  request.addHeader(callIdHeader);
  request.addHeader(cSeqHeader);
  request.addHeader(fromHeader);
  request.addHeader(toHeader);
  request.addHeader(maxForwardsHeader);
  request.addHeader(viaHeader);
  request.addHeader(contactHeader);
  if (response != null) {
  retry = true;
  AuthorizationHeader authHeader = Utils.makeAuthHeader(headerFactory, response,
  request, username, password);
  request.addHeader(authHeader);
  }
  inviteTid = sipProvider.getNewClientTransaction(request);
  // send the request out.
  inviteTid.sendRequest();
  this.dialog = inviteTid.getDialog();
  // Send the request statelessly through the SIP provider.
  //            this.sipProvider.sendRequest(request);

  // Display the message in the text area.
  logger.debug("Request sent:\n" + request.toString() + "\n\n");
  } catch (Exception e) {
  // If an error occurred, display the error.
  e.printStackTrace();
  logger.debug("Request sent failed: " + e.getMessage() + "\n");
  }
}

During a SIP request if the server responds with 401 Proxy Authentication Required or 401 Unauthorized then it means the client has to replay the same request again with MD5 challenge.

The client should use nonce value from the response header WWW-Authenticate.

WWW-Authenticate: Digest realm="sip.linphone.org", nonce="JbAO1QAAAAA3aDI0AADMobiT7toAAAAA", opaque="+GNywA==", algorithm=MD5, qop="auth"

The client should use nonce to generate the MD5 challenge and make the original request again with the Authorization header.

Steps to create the MD5 Challenge

1. Create first MD5 hash using username + “:” + realm + “:” + password

   String a1 = username + ":" + realm + ":" + password; String ha1 = toHexString(mdigest.digest(a1.getBytes()));

2. Create second MD5 hash using request_method + “:” + request_uri

   String a2 = request_method.toUpperCase() + ":" + request_uri; String ha2 = toHexString(mdigest.digest(a2.getBytes()));

3. If qop in the response header is “auth” then the final MD5 hash is calculated using step 3a else if it is undefined or empty refer step 3b.

3a. Create the final MD5 string using ha1 + “:” + nonce + “:” + nonceCount + “:” + cNonce + “:” + qop + “:” + ha2

String finalStr = ha1 + ":" + nonce + ":" + nonceCount + ":" + cNonce + ":" + qop + ":" + ha2; 
String response = toHexString(mdigest.digest(finalStr.getBytes()));

3b. Create the final MD5 string using ha1 + “:” + nonce + “:” + ha2

String finalStr = ha1 + ":" + nonce + ":" + ha2; 
String response = toHexString(mdigest.digest(finalStr.getBytes()));
