私は(AJAX)Wcf Service
からそれを呼び出します。JavaScript
Jquery
コードの一部を次に示します。
IService1.cs:
[ServiceContract]
public interface IService1
{
[WebInvoke(Method = "*",
BodyStyle = WebMessageBodyStyle.Wrapped,
RequestFormat = WebMessageFormat.Json,
ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
User GetUser(string userName, string password);
}
Service1.svc.cs:
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1 : IService1
{
public User GetUser(string userName, string password)
{
//DO SOMETHING
}
}
Service1.svc:
<%@ ServiceHost Language="C#" Debug="true" Service="ProjName.Service1" CodeBehind="Service1.svc.cs" %>
Web.config:

私の JS ページからの Wcf 関数の呼び出し:
function CallService() {
jQuery.ajaxSetup({
error: function (x, e) {
if (x.status == 0) {
alert('You are offline!!\n Please Check Your Network.');
} else if (x.status == 404) {
alert('Requested URL not found.');
} else if (x.status == 500) {
alert('Internal Server Error.');
} else if (e == 'parsererror') {
alert('Error.\nParsing JSON Request failed.');
} else if (e == 'timeout') {
alert('Request Time out.');
} else {
alert('Unknow Error.\n' + x.responseText);
}
}
});
var request = { userName: "aaa", password: "123" };
var jsondata = JSON.stringify(request);
$.ajax({
type: "POST", //GET or POST or PUT or DELETE verb
url: "http://localhost:xxxx/Service1.svc/GetUser", // Location of the service
data: jsondata, //Data sent to server
contentType: "application/json; charset=utf-8", // content type sent to server
dataType: "jsonp", //Expected data format from server
async: false,
processdata: true, //True or False
crossDomain: true, //True or False
success: function (result) {
alert('success');
}
});
}
エラーIE
が発生します:Error. Parsing JSON Request failed.
OnChorme
はエラーの機能に来ていませんが、コンソールでエラーが発生しました:GET http://localhost... 400 (Bad Request) .
GET
を渡したときにエラーが通知される理由とPOST
、Bad Request が何であるかがわかりません。
私はいくつかの助けが大好きです..
