使用 wsHttpBinding 调用 WCF Web 服务器时 Metro 客户端挂起

Question

我已经使用 Metro 1.2 生成了一个带有本地 wsdl 的 Web 服务客户端，如下所示：

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

wsdl 使用 SOAP 1.2 并且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Web服务方法之前设置：

@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;
}

如果我使用错误的用户名/密码，我会得到一个401 Unauthorized 返回，这很好，但是当我使用正确用户名/密码时，呼叫挂起，我从未得到响应！

请求看起来像这样（用netcat捕获它，所以主机不同，并且没有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），但它也永远不会产生一个回应，只是等待。

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

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超级方法：

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metro没有生成这个超出了我的范围。该方法最终如下所示：

@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;
}

这又向消息添加了 SOAP 标头：

<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">
