wcf - Metro 客户端在使用 wsHttpBinding 调用 WCF 网络服务器时挂起

Question

我使用 Metro 1.2 以这种方式生成了一个带有本地 wsdl 的 webservice 客户端:

./wsimport.sh -extension -verbose -wsdllocation service.wsdl -s src -d target service.wsdl -Xendorsed

wsdl 使用 SOAP 1.2 和 wsHttpBinding 。它应该连接到使用 NTLM 作为身份验证方法的 WCF 服务器。

我创建了一个 Authenticator 来处理 NTLM 身份验证:

public class NtlmAuthenticator extends Authenticator
{
    private String username = "";
    private String password = "";

    public NtlmAuthenticator(String username, String password) {
        this.username = username;
        this.password = password;
    }

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication(username, password.toCharArray());
    }
}

我在调用每个 webservice 方法之前设置的:

@WebEndpoint(name = "WSHttpBinding_ICustomerService")
public ICustomerService getWSHttpBindingICustomerService() {
    ICustomerService service =
        super.getPort(new QName("http://xmlns.example.com/services/Customer",
                "WSHttpBinding_ICustomerService"), ICustomerService.class);

    NtlmAuthenticator auth = new NtlmAuthenticator(username, password);  
    Authenticator.setDefault(auth);   

    return service;
}

如果我使用了错误的用户名/密码，我会返回一个 401 Unauthorized，这很好，但是当我使用正确的用户名/密码时，调用会挂起，我永远不会得到响应!

请求看起来是这样的(用netcat捕获的，所以主机不同，没有https):

POST / HTTP/1.1
Content-type: application/soap+xml;charset="utf-8";action="http://xmlns.example.com/services/ICustomerService/GetCustomer"
Password: [password]
Authorization: Basic [auth]
Username: [username]
Accept: application/soap+xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
User-Agent: JAX-WS RI 2.1.7-b01-
Cache-Control: no-cache
Pragma: no-cache
Host: localhost:5500
Connection: keep-alive
Content-Length: 603

[xml follows]

我也尝试过 wget 1.12(听说 1.11 有 NTLM 问题)，但它也从未产生响应，只是等待。

[...]
---request end---
[writing POST file customerRequest.xml ... done]
HTTP request sent, awaiting response... 

我已经看到 others 之前有过这种行为，但我一直无法找出原因。任何人都可以对此有所了解吗？ Linux 上的 JDK 1.6。

我发现我在生成的客户端代码中遗漏了一行启用 Addressing并将其传递给 getPort super 方法:

WebServiceFeature wsAddressing = new AddressingFeature(true);

ICustomerService service =
    super.getPort(new QName("http://xmlns.example.com/services/Customer",
            "WSHttpBinding_ICustomerService"), ICustomerService.class, 
            wsAddressing);

为什么地铁没有产生这个超出我的范围。该方法最终看起来像这样:

@WebEndpoint(name = "WSHttpBinding_ICustomerService")
public ICustomerService getWSHttpBindingICustomerService() {
    WebServiceFeature wsAddressing = new AddressingFeature(true);

    ICustomerService service =
        super.getPort(new QName("http://xmlns.example.com/services/Customer",
                "WSHttpBinding_ICustomerService"), ICustomerService.class, 
                wsAddressing);

    NtlmAuthenticator auth = new NtlmAuthenticator(username, password);  
    Authenticator.setDefault(auth);   

    return service;
}

这反过来又向消息添加了一个 SOAP header :

<S:Header>
  <To xmlns="http://www.w3.org/2005/08/addressing">https://services.example.com/CustomerService.svc</To>
  <Action xmlns="http://www.w3.org/2005/08/addressing">http://xmlns.example.com/services/ICustomerService/GetCustomer</Action>
  <ReplyTo xmlns="http://www.w3.org/2005/08/addressing">
    <Address>http://www.w3.org/2005/08/addressing/anonymous</Address>
  </ReplyTo>
  <MessageID xmlns="http://www.w3.org/2005/08/addressing">uuid:d33c2888-abfa-474d-8729-95d2bcd17a96</MessageID>
</S:Header>
