Question

我有一个仅用于数据的WebService。

使用服务：

 [WebGet(UriTemplate = "maq/?v={v}",
            RequestFormat = WebMessageFormat.Xml,
            ResponseFormat = WebMessageFormat.Xml)]
        [OperationContract]
        List<VoltaPDA> GetAllta(int v);

它完美无缺;

在同一个webService中使用此函数：

[WebGet(UriTemplate = "ped/?T={ti}&V={Vo}",
            RequestFormat = WebMessageFormat.Xml,
            ResponseFormat = WebMessageFormat.Xml)]
        [OperationContract]
        List<Pedido> GetSub(string ti,string Vo);

我得到了error HTTP 400好奇，通过浏览器直接测试都可以正常工作，当我在Windows Mobile 6.5 application上使用它时，第二个函数返回HTTP 400 error。

你能想象它会是什么吗？

两者都访问相同的数据库Sql Server 2012以及WebService中托管的IIS 8.5

通常会从客户端返回Mime-Type不匹配和格式错误的请求（正文和某些时间网址）的默认400响应。

在这种情况下，我建议您检查第二个请求中移动应用程序发送的Content-Type标头，以确保其类似text/xml。

Web服务休息错误http 400
