jQuery调用WCF服务时如何传递对象参数

jQuery调用WCF服务的设置请参考：jQuery调用WCF需要注意的一些问题。

WCF服务接口代码示例：

    
    

     
         [ServiceContract]
    
     
     public
     
      
     
     interface
     
      ICourseService
    {
        [OperationContract]
        
     
     bool
     
      Create(Course course);
    }
    
    

客户端调用代码示例：

    
    

     
     <
     
     script type
     
     =
     
     "
     
     text/javascript
     
     "
     
      src
     
     =
     
     "
     
     /script/jquery.json-2.2.min.js
     
     "
     
     ><
     
     /
     
     script>
     
     

     
     <
     
     script type
     
     =
     
     "
     
     text/javascript
     
     "
     
     >
     
     
    
     
     function
     
      create_course() {
        
     
     var
     
      course 
     
     =
     
      {};
        course.Title 
     
     =
     
      $(
     
     "
     
     #course_title
     
     "
     
     ).val();
        course.CategoryId 
     
     =
     
      $(
     
     "
     
     #course_category
     
     "
     
     ).val();
        course.Frequency 
     
     =
     
      $(
     
     "
     
     #course_frequency
     
     "
     
     ).val();
        course.Alias 
     
     =
     
      $(
     
     "
     
     #course_alias
     
     "
     
     ).val();
        course.Description 
     
     =
     
      $(
     
     "
     
     #course_desc
     
     "
     
     ).val();
        course.IsPublish 
     
     =
     
      $(
     
     "
     
     #is_publish
     
     "
     
     ).attr(
     
     "
     
     checked
     
     "
     
     ).toString();
        
     
     var jsonCourse = $.toJSON(course);//代码1
        var jsonCourse2 = '{"course":' + jsonCourse + '}'
     
     ;//代码2
         $.ajax({
            type: 
     
     "
     
     POST
     
     "
     
     ,
            url: 
     
     "
     
     /wcf/CourseService.svc/Create
     
     "
     
     ,
            data: jsonCourse2,
            contentType: 
     
     "
     
     application/json; charset=utf-8
     
     "
     
     ,
            dataType: 
     
     "
     
     json
     
     "
     
     ,
            success: 
     
     function
     
     (data) {             
            },
            error: 
     
     function
     
     (xhr) {
                
     
     debugger
     
     ;
            }
        });
    }

     
     <
     
     /
     
     script>
    
    

上面代码红色字体部分：

代码1是通过jquery-json插件将JavaScript对象转换为Json格式。

代码2是将代码1得到的Json格式转换为WCF服务接口所需的Json格式，实际格式是：

{"course":{"Title":"test","CategoryId":"1","Frequency":"10","Alias":"test","Description":"testtest","IsPublish":"true"}}
