[OperationContract]
[WebInvoke(UriTemplate = "/GetUserDetails",
RequestFormat= WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json, Method = "POST")]
int GetUserDetails(string strUserID);
下面是另一种方法:
[OperationContract]
[WebGet(UriTemplate = "/GetUserDetails/{strUserID}",
ResponseFormat = WebMessageFormat.Json)]
User GetUserDetails(string strUserID);
而User
是您保存详细信息的自定义类
[DataContract]
public class User
{
[DataMemeber]
public in UserID {get; set;}
// Remaining attributes here.
}
我对AJAX没有太多的经验,但我认为它应该可以工作
url: 'http://<ipaddress>/WcfService1/Service1.svc/GetUserDetails/101'
type: 'GET',
//contentType: "application/json; charset=utf-8", No need to mention it for GET
url:'http:///WcfService1/Service1.svc/GetUserDetails/101'
键入:“GET”,
//contentType:“application/json;charset=utf-8”,无需在GET中提及
一切似乎都很好,
需要检查服务未提供404未在浏览器上找到。
如果您获得404,则需要在Windows server 8或12上的“WCF服务”下添加功能 现在它抛出500个内部服务器错误浏览并检查来自IISMemory gates的服务检查失败,因为可用内存(123486208字节)少于总内存的5%。因此,该服务将无法用于传入请求。要解决此问题,请减少计算机上的负载,或者调整serviceHostingEnvironment配置元素上的minFreeMemoryPercentageToActivateService的值。请按照建议,尝试在您的Web.config中将WCF主机的minFreeMemoryPercentageToActivateService设置为0
url: 'http://<ipaddress>/WcfService1/Service1.svc/GetUserDetails/101'
type: 'GET',
//contentType: "application/json; charset=utf-8", No need to mention it for GET
