我对使用jain sip库进行身份验证有疑问。我正在使用jain sip将注册帐户注册到Asterisk服务器。
只要我尝试添加AuthorizationHeader，就会出现以下错误消息：
The method makeAuthHeader(HeaderFactory, Response, Request, String, String) is undefined for the type Utils
以下是代码段：
AuthorizationHeader authHeader = Utils.makeAuthHeader(
headerFactory, response, request, userId, password);
request.addHeader(authHeader);
似乎无法找到方法makeAuthHeader()。
代码SipClientServiceImpl.java：
@Service("clientService")
public class SipClientServiceImpl implements SipClientService, SipListener {
SipFactory sipFactory; // Used to access the SIP API.
SipStack sipStack; // The SIP stack.
SipProvider sipProvider; // Used to send SIP messages.

嗯，Utils不是API的一部分，它根本没有你想要使用的方法。进行客户端身份验证的最佳方法是使用https://svn.java.net/svn/jsip~svn/trunk/src/examples/authorization/ShootistAuth.java
中的示例这是相关部分：
if (response.getStatusCode() == Response.PROXY_AUTHENTICATION_REQUIRED
|| response.getStatusCode() == Response.UNAUTHORIZED) {
AuthenticationHelper authenticationHelper =
((SipStackExt) sipStack).getAuthenticationHelper(new AccountManagerImpl(), headerFactory);
inviteTid = authenticationHelper.handleChallenge(response, tid, sipProvider, 5);
inviteTid.sendRequest();
invco++;
}

类Utils不拥有此方法，您可以在此处看到： http://grepcode.com/file/repo1.maven.org/maven2/javax.sip/jain-sip-ri/1.2.203/gov/nist/javax/sip/Utils.java 你必须使用不同的东西，但我找不到任何关于使用什么类/方法的东西。
