mjsip下的401和407认证问题

 前久在用mjsip开发sip客户端的时候遇到401和407问题被卡了几天，所以在这做个记录。401我的解决是在注册失败并收到401错误时，把服务器返回的信息重新组装一次，再请求一次，部分代码如下：

Java代码  

1. if (code==401) {   
2.  Message req=transaction.getRequestMessage();   
3.  req.setCSeqHeader(req.getCSeqHeader().incSequenceNumber());   
4.  WwwAuthenticateHeader wah=resp.getWwwAuthenticateHeader();   
5.  String qop_options=wah.getQopOptionsParam();   
6.  printLog("DEBUG: qop-options: "+qop_options,LogLevel.MEDIUM);   
7.  qop=(qop_options!=null)? "auth" : null;   
8.  AuthorizationHeader ah=(new DigestAuthentication(SipMethods.REGISTER,req.getRequestLine().getAddress().toString(),wah,qop,null,username,passwd)).getAuthorizationHeader();   
9.  req.setAuthorizationHeader(ah);   
10.  TransactionClient t=new TransactionClient(sip_provider,req,this);   
11.  t.request();   
12.  }  

            if (code==401) {            Message req=transaction.getRequestMessage();            req.setCSeqHeader(req.getCSeqHeader().incSequenceNumber());            WwwAuthenticateHeader wah=resp.getWwwAuthenticateHeader();            String qop_options=wah.getQopOptionsParam();            printLog("DEBUG: qop-options: "+qop_options,LogLevel.MEDIUM);            qop=(qop_options!=null)? "auth" : null;            AuthorizationHeader ah=(new DigestAuthentication(SipMethods.REGISTER,req.getRequestLine().getAddress().toString(),wah,qop,null,username,passwd)).getAuthorizationHeader();            req.setAuthorizationHeader(ah);            TransactionClient t=new TransactionClient(sip_provider,req,this);            t.request();             }

 同样的方式解决407问题，所不同的是在发出invite后要回应一个ack信息，代码如下：

Java代码  

1. if(code==407){   
2.      Message ack = MessageFactory.createRequest(sip_provider, SipMethods.ACK, to, from, null);   
3.      ack.setCallIdHeader(req.getCallIdHeader());   
4.      TransactionClient t=new TransactionClient(sip_provider,ack,this);    
5.        t.request();   
6. }   
7. if ((code==407)){   
8.        req.setCSeqHeader(req.getCSeqHeader().incSequenceNumber());   
9.        WwwAuthenticateHeader wah;   
10.        wah=msg.getProxyAuthenticateHeader();   
11.        String qop_options=wah.getQopOptionsParam();   
12.        qop=(qop_options!=null)? "auth" : null;   
13.        RequestLine rl=req.getRequestLine();   
14.        DigestAuthentication digest=new DigestAuthentication(rl.getMethod(),rl.getAddress().toString(),wah,qop,null,username,password);   
15.        AuthorizationHeader ah;   
16.        ah=digest.getProxyAuthorizationHeader();   
17.        req.setAuthorizationHeader(ah);   
18.        transactions.remove(tc.getTransactionId());   
19.        tc=new TransactionClient(sip_provider,req,this);   
20.        transactions.put(tc.getTransactionId(),tc);   
21.        tc.request();   
22. }  

            if(code==407){                Message ack = MessageFactory.createRequest(sip_provider, SipMethods.ACK, to, from, null);                ack.setCallIdHeader(req.getCallIdHeader());                TransactionClient t=new TransactionClient(sip_provider,ack,this);                    t.request();            }            if ((code==407)){                   req.setCSeqHeader(req.getCSeqHeader().incSequenceNumber());                   WwwAuthenticateHeader wah;                   wah=msg.getProxyAuthenticateHeader();                   String qop_options=wah.getQopOptionsParam();                   qop=(qop_options!=null)? "auth" : null;                   RequestLine rl=req.getRequestLine();                   DigestAuthentication digest=new DigestAuthentication(rl.getMethod(),rl.getAddress().toString(),wah,qop,null,username,password);                   AuthorizationHeader ah;                   ah=digest.getProxyAuthorizationHeader();                   req.setAuthorizationHeader(ah);                   transactions.remove(tc.getTransactionId());                   tc=new TransactionClient(sip_provider,req,this);                   transactions.put(tc.getTransactionId(),tc);                   tc.request();            }
