Android JSON发布到WCF服务

Question

我的Android客户端试图将JSON类发布到我的wcf服务时出现问题。 下面是Android客户端的代码：为WCF

[OperationContract] 
    [WebInvoke(Method = "POST", 
     RequestFormat = WebMessageFormat.Json, 
     ResponseFormat = WebMessageFormat.Json, 
     BodyStyle = WebMessageBodyStyle.Wrapped, 
     UriTemplate = "TestPost")] 
    void TestPost(TestModel tm); 





[DataContract] 
public class TestModel 
{ 
    [DataMember(Name = "p1")] 
    public string p1 { get; set; } 

    [DataMember(Name = "p2")] 
    public string p2{ get; set; } 

    [DataMember(Name = "p3")] 
    public int p3 { get; set; } 

    [DataMember(Name = "p4")] 
    public string p4 { get; set; } 

    [DataMember(Name = "p5")] 
    public int p5 { get; set; } 

    [DataMember(Name = "p6")] 
    public string p6 { get; set; } 

}

在我的WCF方法的参数TestModel TM总是空

public HttpResponse TestPost() throws Exception 
{ 

    HttpPost httpost = new HttpPost(url+"/TestPost"); 

    JSONStringer img = new JSONStringer() 
     .object() 
     .key("TestModel") 
      .object() 
       .key("p1").value("test") 
       .key("p2").value("test") 
       .key("p3").value(1) 
       .key("p4").value("test") 
       .key("p5").value(2) 
       .key("p6").value("test;test") 
      .endObject() 
     .endObject(); 
     StringEntity se = new StringEntity(img.toString()); 

    httpost.setEntity(se); 

    httpost.setHeader("Accept", "application/json"); 
    httpost.setHeader("Content-type", "application/json"); 

    return httpclient.execute(httpost); 
} 

这里是代码。什么可能是错的？

对象的包装（自从您指定WebMessageBodyStyle.Wrapped）是基于参数名称而不是参数类型完成的。最外面的JSON成员的名称应该是“tm”，而不是“TestModel”：

public HttpResponse TestPost() throws Exception 
{ 
    HttpPost httpost = new HttpPost(url+"/TestPost"); 

    JSONStringer img = new JSONStringer() 
     .object() 
     .key("tm") 
      .object() 
       .key("p1").value("test") 
       .key("p2").value("test") 
       .key("p3").value(1) 
       .key("p4").value("test") 
       .key("p5").value(2) 
       .key("p6").value("test;test") 
      .endObject() 
     .endObject(); 
     StringEntity se = new StringEntity(img.toString()); 

    httpost.setEntity(se); 

    httpost.setHeader("Accept", "application/json"); 
    httpost.setHeader("Content-type", "application/json"); 

    return httpclient.execute(httpost); 
}
