android调用WCF(多参数传递)

1，使用的交互方式是json格式，返回与提交参数都是json字符串。

2，对于多个参数的提交注意点：必须封装在一个jsonobject内如：{"param1":{"id":1,"name":"kee"},"param2":{"id":2,"name":"temp"}},此处提交的参数对应的函数

形式fun(Person param1,Person param2)。封装的key值，是函数参数的名称。这也是摸搜了好久，验证成功的啦。

在.net WCF端接口函数   

GetPersonInfoDetailByStudent(ServiceRequest serviceRequest,Student student1,Student student2)

下面是Android端简单的测试代码：
