JSONP跨域WCF服务响应失败 [英] JSONP CROSS- DOMAIN WCF Service Response Fail

问题描述

这是WCF服务代码:

This is the WCF Service code:

[OperationContract]
        [WebGet(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
        public String GreetJson()
        {
            Greeting g = new Greeting();
            g.Message = "Hello World!";
            Console.WriteLine("call received");
            JavaScriptSerializer serializer = new JavaScriptSerializer();

            return serializer.Serialize(g); ;
        }

和客户要求:

and the client request:

$("#test").click(function(){
$.getJSON("http://192.168.10.183:8001/GreetJson",function(data)
            {
                alert("test=" + data);
            });
});
...
<img src="data/images/menu/highscore.png" alt="Highscore" id="test" />

如果我们在浏览器中使用http://192.168.10.183:8001/GreetJson，则会得到:
"{\" Message \:\" Hello World！\}"

我们的问题是，当我们执行getJSON请求时，我们没有从服务器收到任何响应.

Console.WriteLine(已接电话"); //该消息出现在控制台中，但在浏览器上没有警报框.
知道为什么吗?

if we use http://192.168.10.183:8001/GreetJson in a browser we get:
"{\"Message\":\"Hello World!\"}"

Our problem is that we don''t receive any response from the server when we do getJSON request.

Console.WriteLine("call received"); //the message appears in the console but on the browser there is no alert box.
Any idea why?

推荐答案

(" ).click(function(){

("#test").click(function(){

.getJSON(" http://192.168.10.183:8001/GreetJson"，功能(数据) { alert(" + data); }); }); ... < img =" data/images/menu/highscore.png" alt =" id / >

.getJSON("http://192.168.10.183:8001/GreetJson",function(data) { alert("test=" + data); }); }); ... <img src="data/images/menu/highscore.png" alt="Highscore" id="test" />
