Question

我在WCF服务中调用一个简单方法时遇到问题。我被卡住了，我不知道如何解决这个问题。我将不胜感激。

我的WCF服务：

[ServiceContract]
interface IMyService
{
    [OperationContract]
    string GetSomething();
}

[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
class MyService : IMyService
{
    [WebInvoke(Method = "GET", 
               RequestFormat = WebMessageFormat.Json, 
               ResponseFormat = WebMessageFormat.Json, 
               UriTemplate = "GetSomething", 
               BodyStyle = WebMessageBodyStyle.Bare)]
    public string GetSomething() 
    {
        return "Hello";
    } 

}

启动服务：

            using (ServiceHost host = new ServiceHost(typeof(MyService)))
        {
            host.Open(); // end point specified in app config

            Console.WriteLine("Hit Enter to quit.");
            Console.ReadLine();
        }

App.Config文件

<configuration>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webHttp">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBinding" crossDomainScriptAccessEnabled="true"/> 
      </webHttpBinding>
    </bindings>
    <services>
      <service name="testWCF.MyService">
        <endpoint address="http://localhost:8003/myservice"
          binding="webHttpBinding"
          contract="testWCF.IMyService"
          behaviorConfiguration="webHttp"/>
      </service>
    </services>
  </system.serviceModel>
</configuration>

关于WCF服务的全部内容。我的Web应用程序正在http://127.0.0.1:8085上运行，以下是我从Web应用程序发送jQuery请求的方法：

$.ajax({
    url: "http://127.0.0.1:8003/myservice/GetSomething?callback=?",
    dataType: 'jsonp',
    cache: false,
    beforeSend: function () {
        console.log("Loading");
    },

    error: function (jqXHR, textStatus, errorThrown) {
        console.log(jqXHR);
        console.log(textStatus);
        console.log(errorThrown);
    },

    success: function (data) {
        console.log('Success');
        console.log(data);
    },

    complete: function () {
        console.log('Finished all tasks');
    }
});

我的回复如下：我可以在我的chrome中看到我的chrome，该响应已经从WCF服务发送（GetSomething方法的内容是“Hello”），但我得到了以下控制台输出：

Loading
GetSomething:-1Resource interpreted as Script but transferred with MIME type application/json.
Object
parsererror
Error: jQuery1101030437586596235633_1390485791492 was not called

我的成功功能从未执行过。当我跟踪一些与此相似的帖子时，我发现它与Content-Type有关，但我找不到如何让这项工作。有人能帮助我吗？

我自己解决了这个问题。问题出在App.config文件中。我添加了bindingConfiguration="webHttpBinding"

现在我的App.config文件是：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <behaviors>
      <endpointBehaviors>
        <behavior name="webHttp">
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <bindings>
      <webHttpBinding>
        <binding name="webHttpBinding" crossDomainScriptAccessEnabled="true"/> 
      </webHttpBinding>
    </bindings>
    <services>
      <service name="testWCF.MyService">
        <endpoint address="http://localhost:8003/myservice"
          binding="webHttpBinding"
          bindingConfiguration="webHttpBinding"
          contract="testWCF.IMyService"
          behaviorConfiguration="webHttp"/>
      </service>
    </services>
  </system.serviceModel>
</configuration>

对WCF服务的jQuery请求以parsererror结束（错误：未调用jQuery1101030437586596235633_1390485791492）
