如何使用JSON请求调用Restful服务c＃ [英] How to Invoke Restful Service with JSON request c#
问题描述
我正在尝试使用Json格式的请求调用.net中开发的REST服务。但是，REST服务可以正常处理xml格式的请求。如果下面定义RequestFormat的方式有任何问题，请告诉我。
这是接口代码：
[ServiceContract]
公共接口ISalesOrderPostService
{
// POST操作
[OperationContract]
[WebInvoke（UriTemplate =，ResponseFormat = WebMessageFormat.Json，RequestFormat = WebMessageFormat.Json，Method =POST）]
String PostSalesOrder（SalesOrder sales_order）;
}
以下是回复：

I am trying to invoke a REST Service developed in .net with request in Json format. However, the REST service works fine with the request in xml format. Can you please let me know if there is any issue in the way the RequestFormat is defined below.
Here is the interface code:
[ServiceContract]
public interface ISalesOrderPostService
{
//POST operation
[OperationContract]
[WebInvoke(UriTemplate = "", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, Method = "POST")]
String PostSalesOrder(SalesOrder sales_order);
}
Here is the Response:
