启用WCF服务以与JSON一起使用

Question

我已经创建了一个wcf服务。当我在.net中简单地通过添加when服务来使用时，它工作得很好。但我想让它能够用于iPhone应用程序作为JSON调用。为了测试，我在.net中使用了JSON，但它不起作用。

我知道以前有人问过这样的问题，我一直在寻找这个无法为我找到答案的问题。

我的配置：

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="servicebehavior">
      <serviceMetadata httpsGetEnabled="true" />
    </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
    <behavior name="endpointBehavior">
      <enableWebScript />
      <webHttp defaultBodyStyle="Wrapped" defaultOutgoingResponseFormat="Json" />
    </behavior>
  </endpointBehaviors>

</behaviors>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>
  <service name="MyService" behaviorConfiguration="servicebehavior">
    <endpoint address=""
              behaviorConfiguration="endpointBehavior"
              binding="webHttpBinding"
              contract="IMyService" />
  </service>
</services>

​

接口代码：

[ServiceContract]
public interface IGolfPyramidService
{



    [WebInvoke(UriTemplate = "/Test", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    [OperationContract]
    string Test();

}

Myservice.cs代码：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MyService : IMyService
{        
    public string Test()
    {
        return "success";
    }
}

我希望能够使用url格式调用该方法，例如：http://example.com/MyService.svc/test

如果你是初学者，这将指导你创建支持json和xml的web服务，可以在IOS和android上使用。

为什么要使用post方法来获取简单的字符串值？尝试这个示例，它应该正常工作。

配置

  <system.serviceModel>
<services>
  <service behaviorConfiguration="RestServiceBehavior" name="WcfService1.MyService">
    <endpoint address="" behaviorConfiguration="web" binding="webHttpBinding" bindingConfiguration="webHttpBindingWithJSONP" contract="WcfService1.IMyService" />
  </service>
</services>
<bindings>
  <webHttpBinding>
    <binding name="webHttpBindingWithJSONP" />
  </webHttpBinding>
</bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp />
    </behavior>
  </endpointBehaviors>
  <serviceBehaviors>
    <behavior name="RestServiceBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

IMyService.cs

namespace WcfService1
{
[ServiceContract]
public interface IMyService
{
    [WebGet(UriTemplate = "Test",
        ResponseFormat = WebMessageFormat.Json
    )]
    [OperationContract]
    string Test();
}
}

MyService.svc.cs

namespace WcfService1
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class MyService : IMyService
{
    public string Test()
    {
        return "Test";
    }
}
}
