使用WCF over HTTP连接到受密码保护的服务器

问题描述

我需要使用WCF将我的ASP.NET MVC应用程序连接到网络上的服务器。该服务器受用户名和密码保护，但似乎它不是https而是简单的http。

I need to connect my ASP.NET MVC application to a server on the net with WCF. The server is username and password protected but it appears that its not a https but a simple http.

这是我到目前为止的代码：

This is the code I have so far :

public MyObject GetMyData(string id)
{
    ChannelFactory<MyIService> factory;
    ClientCredentials loginCredentials = new ClientCredentials();

    loginCredentials.UserName.UserName = "MyName";
    loginCredentials.UserName.Password = "MyPassword";

    factory = new ChannelFactory<ICFService>("MyData");

    var defaultCredentials = factory.Endpoint.Behaviors.Find<ClientCredentials>();
    factory.Endpoint.Behaviors.Remove(defaultCredentials); //remove default ones
    factory.Endpoint.Behaviors.Add(loginCredentials); //add required ones

    var proxy = factory.CreateChannel();
    var response = proxy.GetMyData(id);
    ((IDisposable)proxy).Dispose();

    return response as MyObject ;
}

这是放在我的web.config中

And this is placed in my web.config

  <system.serviceModel>
    <client>
      <endpoint address="http://MyUrl/"
                binding="webHttpBinding"
                behaviorConfiguration="MyData"
                contract="MyNameSpace.MyIService"
                name="MyData"/>
    </client>
    <behaviors>
      <endpointBehaviors>
        <behavior name="MyData">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

  </system.serviceModel>

问题在于我得到以下异常：

The problem is that I get the following exception :

远程服务器返回错误：（401）未经授权。
描述：执行当前Web请求期间发生了未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。
异常详细信息：System.Net.WebException：远程服务器返回错误：（401）未经授权。

我知道服务器那个我试图与之通信只会在我的应用程序被放置在特定的IP nr上时进行通信，但这已经完成并且应该有效。

I know that the server that I am trying to communicate with will only communicate if my application is placed on a specific IP nr but this is already done and should work.

请求建议

编辑1：

这就是服务的样子：

[ServiceContract]
[XmlSerializerFormat]
public interface ICFService
{
    [OperationContract]
    [WebGet(BodyStyle = WebMessageBodyStyle.Bare,
        ResponseFormat = WebMessageFormat.Xml,
        UriTemplate = "get?UID=12345.eu_vddsall_xml&MyId={MyId}&LANG=en")]
    CFExtendedDescription GetMyData(string MyId);

}

Edit2：
这是在Firefox中浏览url时对话框的样子。我不知道如何检查Proxy.GetMyData将使用的实际网址。

This is how the dialog looks like when browsing the url in firefox. Im not sure how to check the acctual url that the Proxy.GetMyData will use.

请注意，这是一个例子，地址和网站说是别的。

我要使用的网址如下所示：

The Url that I am supose to use looks like this :

http://bat.myserver.com/ag/get?UID=12345.eu_vddsall_xml&MyId=WRH421&LANG=sv

通过向web.config添加愚蠢，我们向前迈了一步（感谢Ladislav Mrnka）：

By adding the foolowing to the web.config we got a step forward (thanks Ladislav Mrnka) :

<bindings>
  <webHttpBinding>
    <binding name="secured">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" />
      </security>
    </binding>
  </webHttpBinding>
</bindings>

现在我们得到以下异常：

Now we get the following exception instead :

无法使用根名称'Binary'和根命名空间''反序列化XML主体（用于操作'GetMyData'和契约（'ICFService'，''））使用XmlSerializer。确保将与XML对应的类型添加到服务的已知类型集合中。

首先我认为远程服务器maby返回了一个xml文档这表明我在错误的IP上，所以我将网站上传到正确的服务器（使用正确的IP），但我在那里得到了同样的例外？

First I thought that the remote server maby returned a xml document that shows that I am on the wrong IP so I uploaded the site to the correct server(with the correct ip) but I get the same exception there?

感谢Ladislav Mrnka提供的帮助！

推荐答案

如果您不知道怎么做，您应该问服务提供商如何获得服务？找到它。

You should ask service provider how is service secured if you don't know how to find it.

您的网站似乎正在使用基本的HTTP身份验证。对于此类身份验证，您需要创建自定义 webHttpBinding 配置：

It looks like your site is using basic HTTP authentication. For such authentication you need to create custom webHttpBinding configuration:

<system.serviceModel>
  <client>
    <endpoint address="http://MyUrl/"
              binding="webHttpBinding"
              bindingConfiguration="secured"
              behaviorConfiguration="MyData"
              contract="MyNameSpace.MyIService"
              name="MyData"/>
  </client>
  <bindings>
    <webHttpBinding>
      <binding name="secured">
        <security mode="TransportCredentialOnly">
          <transport clientCredentialType="Basic" />
        </security>
      </binding>
    </webHttpBinding>
  </bindings>
  <behaviors>
    <endpointBehaviors>
      <behavior name="MyData">
        <webHttp/>
      </behavior>
    </endpointBehaviors>
  </behaviors>
</system.serviceModel>
