使用 WCF 的 Http 请求中缺少授权标头 [英] Authorization Header is missing in Http request using WCF

问题描述

我正在使用 WCF 访问 Web 服务.使用 WSHttpBinding，安全模式设置为传输 (https)，​​客户端凭据类型为基本.当我尝试使用代理访问服务时，收到 401 未经授权的异常.

I am accessing a web service using WCF. Using WSHttpBinding, Security mode is set Transport (https) and client credential type is Basic. When I try to access the service using the proxy, getting an 401 unauthorized exception.

这里是绑定

var binding = new WSHttpBinding()
        {
            UseDefaultWebProxy = true,
            Security =
            {
                Mode = SecurityMode.Transport,
                Transport =
                {
                    ClientCredentialType = HttpClientCredentialType.Basic,
                },
            }
        };

这里是服务调用

var client = new InternetClient(binding, new EndpointAddress("httpsurl"));

        client.ClientCredentials.UserName.UserName = "username";
        client.ClientCredentials.UserName.Password = "password";
        client.ProcessMessage("somevalue");

当使用 Http Analyzer 查看 Http 标头时连接头

When looked into Http headers using Http Analyzer CONNECT HEADER

(请求行):CONNECT somehost.com:443 HTTP/1.1
主持人:somehost.com
代理连接:保持活动

(Request-Line):CONNECT somehost.com:443 HTTP/1.1
Host:somehost.com
Proxy-Connection:Keep-Alive

如果您看到标头授权标头丢失

If you see the header Authorization header is missing

现在我的问题是为什么 WCF 调用缺少授权标头?我错过了什么吗?.请询问您是否需要更多信息

Now my question is why WCF call missing the Authorization header? Am I missing something? . Please ask if you need more information

推荐答案

其实这个问题我错了.在运行 HTTP 分析器时，我确实看到了不同的行为.在 Http anaylzer 运行时，我的应用程序在收到 401 响应后崩溃.当 Http 分析器应用程序关闭时，上述代码按预期工作.

Actually, I was wrong about this question. I did see different behaviour when running HTTP analyzer. While Http anaylzer running, my application crashed after receiving 401 response. When Http analyzer application closed, the above code worked as expected.
