使用 c#.Net 读取 WebService Wsdl

Question

我们有一个基于 SOAP 的 Web 服务，当我们在浏览器中输入 url 时，我们能够读取它的 wsdl。我们坐在我们网络中的代理后面，但它没有阻止任何东西，当我们在浏览器中输入 url 时，我们总是能够使用 browser.But 读取 wsdl 说 http://ist.services/CoreServices/coreservices?wsdl 它要求输入用户名和密码这与我的 windows 凭据不同。因此，当我输入开发团队共享的用户名和密码时，它 returns wsdl 页面。请注意，此 Web 服务是在基于 java 的服务器上开发和部署的。

如何在 c#.net 代码中执行相同的操作以及如何在 DiscoveryClientProtocol 中传递安全凭证？我尝试了下面的代码，它适用于不需要安全凭证的网络服务。

  // Specify the URL to discover.
        string sourceUrl = "http://ist.services/CoreServices/coreservices?wsdl";

        string outputDirectory = "C:\Temp";

        DiscoveryClientProtocol client = new DiscoveryClientProtocol();
        var credentials = new NetworkCredential("sunuser1", "xxxxxxx", "");

        WebProxy proxy = new WebProxy("http://proxy.bingo:8000/", true) { Credentials = credentials };

           client.Credentials = credentials;
        // Use default credentials to access the URL being discovered.
        //client.Credentials = credentials;//CredentialCache.DefaultCredentials;
        client.Proxy = proxy;
        String DiscoverMode = "DiscoverAny";
        String ResolveMode = "ResolveAll";
        try
        {
            DiscoveryDocument doc;
            // Check to see if whether the user wanted to read in existing discovery results.
            if (DiscoverMode == "ReadAll")
            {
                DiscoveryClientResultCollection results = client.ReadAll(Path.Combine("C:\Temp", "results.discomap"));
                //SaveMode.Value = "NoSave";
            }
            else
            {
                // Check to see if whether the user wants the capability to discover any kind of discoverable document.
                if (DiscoverMode == "DiscoverAny")
                {
                    doc = client.DiscoverAny(sourceUrl);
                }
                else
                // Discover only discovery documents, which might contain references to other types of discoverable documents.
                {
                    doc = client.Discover(sourceUrl);
                }
                // Check to see whether the user wants to resolve all possible references from the supplied URL.
                if (ResolveMode == "ResolveAll")
                    client.ResolveAll();
                else
                {
                    // Check to see whether the user wants to resolve references nested more than one level deep.
                    if (ResolveMode == "ResolveOneLevel")
                        client.ResolveOneLevel();
                    else
                        Console.WriteLine("empty");
                }
            }
        }
        catch (Exception e2)
        {
            //DiscoveryResultsGrid.Columns.Clear();
            //Status.Text = e2.Message;
            Console.WriteLine(e2.Message);
        }
        // If documents were discovered, display the results in a data grid.
        if (client.Documents.Count > 0)
            Console.WriteLine(client);

    }
    }

由于代码对我帮助不大，当我在浏览器中手动读取 wsdl 时，我打开了 fiddler 来跟踪 http 调用，我看到它采用我输入的凭据作为 "Authorization: Basic cGDFDdsfdfsdsfdsgsgfg="。在 fiddler 中，我看到三个响应分别为 401,302 和 200 的调用。但是在我的 c#.net 代码中，我没有得到 200 响应，它总是抛出 404 错误。

我对此进行了进一步调试，在客户端对象的 httpresponse 中，我看到标志状态为 INVOCATION_FLAGS_INITIALIZED | INVOCATION_FLAGS_NEED_SECURITY

看来我需要将凭据作为安全凭据而不是网络凭据传递。

下面的代码已经解决了这个问题。

        CredentialCache myCredentialCache = new CredentialCache { { new Uri(sourceUrl),
                "Basic", networkCredential } };

        discoveryClientProtocol.AllowAutoRedirect = true;
        discoveryClientProtocol.Credentials = myCredentialCache;
