跨域调用WCF服务(Cross

跨域调用WCF服务(Cross-domain calling a WCF Service)

我有一个WCF服务，这是一个我要调用的方法：

[OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)] double?[] GetPoints(string tourname);

我通过WCF测试客户端检查，它工作正常

所以我需要从html页面调用这个方法。它应该适用于跨域的其他计算机。

我用jQuery 1-6-2.min.js写了一些东西：

var varType; var varUrl; var varData; var varContentType; var varDataType; var varProcessData; function CallService() { alert("CallService"); $.ajax({ type : varType, //GET or POST or PUT or DELETE verb url : varUrl, // Location of the service data : varData, //Data sent to server contentType : varContentType, // content type sent to server dataType : varDataType, //Expected data format from server processdata : varProcessData, //True or False success : function(msg) {//On Successfull service call ServiceSucceeded(msg); }, error: ServiceFailed// When Service call fails }); } function Start() { varType = "POST"; varUrl = "http://localhost:1592/TourService.svc/GetPoints"; varData = '{"tourname ":"customname"}'; varContentType = "application/json; charset=utf-8"; varDataType = "json"; varProcessData = true; CallService(); } function ServiceSucceeded(result) { alert("ServiceSucceeded"); alert(result); } function ServiceFailed(result) { alert('Service call failed: ' + result.status + ' ' + result.statusText); varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null; }

但是调用了ServiceFailed函数，并显示消息“服务调用失败0错误”

如何进行WCF服务的跨域调用？（使用jQuery与否）

谢谢

I have a WCF service, this is a method which I'd to call:

[OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)] double?[] GetPoints(string tourname);

I checked by WCF Test Client, it works fine

So I need to call this method from html page. It should work from other computer that is cross-domain.

I wrote somethig using jQuery 1-6-2.min.js:

var varType; var varUrl; var varData; var varContentType; var varDataType; var varProcessData; function CallService() { alert("CallService"); $.ajax({ type : varType, //GET or POST or PUT or DELETE verb url : varUrl, // Location of the service data : varData, //Data sent to server contentType : varContentType, // content type sent to server dataType : varDataType, //Expected data format from server processdata : varProcessData, //True or False success : function(msg) {//On Successfull service call ServiceSucceeded(msg); }, error: ServiceFailed// When Service call fails }); } function Start() { varType = "POST"; varUrl = "http://localhost:1592/TourService.svc/GetPoints"; varData = '{"tourname ":"customname"}'; varContentType = "application/json; charset=utf-8"; varDataType = "json"; varProcessData = true; CallService(); } function ServiceSucceeded(result) { alert("ServiceSucceeded"); alert(result); } function ServiceFailed(result) { alert('Service call failed: ' + result.status + ' ' + result.statusText); varType = null; varUrl = null; varData = null; varContentType = null; varDataType = null; varProcessData = null; }

However ServiceFailed function is invoked with message "Service call failed 0 error"

How to make a cross-domain calling of WCF service?(using jQuery or not)

Thanks
