Wcf服务:
namespace WcfService1
{
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]
public class Service1 : IService1
{
public string GetUserDetails(string userId)
{
// Returns User Details
}
}
}
接口:IService1.cs
Interface : IService1.cs
namespace WcfService1
{
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
int GetUserDetails(string strUserID);
}
}
WebConfig文件:

推荐答案
这是另一种解决方法:
[OperationContract]
[WebGet(UriTemplate = "/GetUserDetails/{strUserID}",
ResponseFormat = WebMessageFormat.Json)]
User GetUserDetails(string strUserID);
User是您的自定义类保存的详细信息.
And User is your custom class holding detail.
[DataContract]
public class User
{
[DataMemeber]
public in UserID {get; set;}
// Remaining attributes here.
}
我对AJAX没有太多经验，但是我认为它应该可以工作.
I don't have much experience with AJAX but I think it should work.
url: 'http://<ipaddress>/WcfService1/Service1.svc/GetUserDetails/101'
type: 'GET',
//contentType: "application/json; charset=utf-8", No need to mention it for GET
