【问题描述】：
这是我为 Android 设备创建的用于发布数据的服务，但该服务对我不起作用。我通过 Android 调用了该服务，但没有任何反应，只是在 LogCat 中收到 -500 的错误消息。我还在 HTTP 和 SIMPLE REST Client（Google Chrome 扩展程序）上检查了此服务，但收到了一条错误消息。错误信息如下。而且这个服务也在IIS上发布。
错误信息
The message with Action '' cannot be processed at the receiver,due to a ContractFilter mismatch at the EndpointDispatcher.
This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.
Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None)
这些是我传递给服务的参数：
{"mycar":{"Name":"a","Make":"gfgfd ","Model":"web "}}
这里是服务源代码
namespace CarSercive
{
[ServiceBehavior(AddressFilterMode=AddressFilterMode.Any)]
public class Service1 : IService1
{
// myCar test = new myCar();
public void UpdateMyCar(myCar mycar) {
string strConnectionString = ConfigurationManager.ConnectionStrings["Database1"].ConnectionString;
SqlConnection conn = new SqlConnection(strConnectionString);
conn.Open();
using (SqlCommand cmd = new SqlCommand("Insert into TestingTable (Name,Make,Model) Values (@Name,@Make,@Model)", conn)) {
cmd.Parameters.AddWithValue("@Name", mycar.Name);
cmd.Parameters.AddWithValue("@Make", mycar.Make);
cmd.Parameters.AddWithValue("@Model", mycar.Model);
int queryResult = cmd.ExecuteNonQuery();
} conn.Close();
}
}
}
