我在过去2年与WCF合作，但每次发送POST请求都会让我感到很挣扎。

I am working with WCF from past 2 years, but every time i send a POST request it makes me struggle a lot.

最终，此请求将从iPhone发送到WCF。

Eventually, this request would be sent from iPhone to WCF.

当我用Fiddler检查时，错误主要是：*服务器遇到处理请求的错误。异常消息是'传入消息具有意外的消息格式'Raw'。该操作的预期消息格式是'Xml'，'Json'。这可能是因为尚未在绑定上配置WebContentTypeMapper。有关更多详细信息，请参阅WebContentTypeMapper的文档。请参阅服务器日志以获取更多详异常堆栈跟踪是：

When i check it with Fiddler the error mostly is: *The server encountered an error processing the request. The exception message is 'The incoming message has an unexpected message format 'Raw'. The expected message formats for the operation are 'Xml', 'Json'. This can be because a WebContentTypeMapper has not been configured on the binding. See the documentation of WebContentTypeMapper for more details.'. See server logs for more details. The exception stack trace is: at

推荐答案

在您的解决方案中添加 Global.ascx 文件并将代码替换为以下

Add a Global.ascx file in youe solution and replace the code with following

protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
    if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
    {
        HttpContext.Current.Response.AddHeader("Cache-Control", "no-cache");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST");
        HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "Content-Type, Accept");
        HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000");
        HttpContext.Current.Response.End();
    }
}

还有一件事chnage dataType ：'text'

one more thing chnage dataType:'text'

$.ajax({
    type: "POST",
    url: "http://localhost:4638/Edulink.svc/SaveUserData",                        
    dataType: "text",
    contentType: "application/json",
    data:'{"EmailID":"praveen", "LevelID": 1}',         
    success:function(data, status) {             
        console.log(data); //gives 1                
    },
    error:function(request, status, error) {
        alert("o0ops");           
    }
});
