WCF REST服務返回（400）錯誤的請求

Question

我是WCF REST的新手，我創建了一個簡單的WCF應用程序並嘗試使用它，但我不斷收到錯誤消息：

遠程服務器返回錯誤：（400）錯誤的請求

我的方法：

[OperationContract]
[WebGet(UriTemplate="mymethod")]
string nameInput();

通過使用以下代碼消耗：

string uri = "http://localhost:53551/HelloNameService.svc/mymethod";
req = (HttpWebRequest)WebRequest.Create(uri);

try
{
    resp = req.GetResponse() as HttpWebResponse;
}
catch(Exception ex)
{
    Console.WriteLine(ex);
}

Stream stream = resp.GetResponseStream();
StreamReader reader = new StreamReader(stream);

string value = reader.ReadToEnd();
label1.Text = value;

web.config中：

<configuration>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="mexBehaviors">
                    <serviceMetadata httpGetEnabled="true"/>
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <services>
            <service name="MyServiceBecouseError.MyNameService" 
                     behaviorConfiguration="mexBehaviors">
                <endpoint 
                    address="" 
                    binding="basicHttpBinding" 
                    contract="MyServiceBecouseError.IMyNameService"/>
            </service>
        </services>
    </system.serviceModel>
    <system.webServer>
        <directoryBrowse enabled="true"/>
    </system.webServer>
    <system.web>
        <compilation debug="true"/>
    </system.web>
</configuration>

您缺少帶有webHttpBinding的終結點。 請使用以下配置，您應該會很好。

  <configuration>
    <system.serviceModel>
      <services>
        <service behaviorConfiguration="MyServiceBehavior" name="MyService">
          <endpoint address="" binding="webHttpBinding" behaviorConfiguration="web" contract="MyServiceBecouseError.IMyNameService"/>                 
          <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="MyServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
   </system.serviceModel>
  </configuration>
