C# 如何使用wcf服务创建android登录
我已经为登录创建了wcf服务方法 我想在android客户端执行登录操作。但当我将JSON格式的对象发布到WCF服务时，我在包装配置中得到一个空对象，或者在裸配置中得到一个字段为空的对象。有人能解决这个问题吗 这是我的Iservice1C# 如何使用wcf服务创建android登录,c#,android,wcf,C#,Android,Wcf,我已经为登录创建了wcf服务方法 我想在android客户端执行登录操作。但当我将JSON格式的对象发布到WCF服务时，我在包装配置中得到一个空对象，或者在裸配置中得到一个字段为空的对象。有人能解决这个问题吗 这是我的Iservice1 [OperationContract] [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, U

警告：这并不能直接回答您的问题，但它确实提供了一种替代实现
我建议使用WebAPI而不是WCF与Android客户端进行通信。WebAPI实现了RESTful、JSON web服务，Android可能更容易使用这些服务，并且比WCF更易于编写。请确保开始。如果您熟悉ASP.Net MVC，那么切换到WebAPI应该是轻而易举的事。发布完整的日志catNot Found-您可以连接到web服务吗？是的，我可以连接我的web服务WCF还可以非常轻松地实现REST。只需在配置文件中使用webhttpbinding添加端点。 12-16 16:22:55.854 1152-1152/?
