推荐答案

您想得到Ajax的回复吗?如果尝试使用Fiddler或PostMan发送请求,则会收到如下所示的响应,并且可以检索json对象.

Did you want to get response from Ajax? If you try Fiddler or PostMan to send request, you will get response like below, and you could retrieve the json object.

{
  "COSendTubeInfoResult": 123,
  "ErrMsg": "Error"
}

这是一个简单的演示,可让Ajax获得响应.

Here is a simple demo for getting response by Ajax.

//WCF Rest Service
//IService
        [OperationContract]
        [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Json,
           ResponseFormat = WebMessageFormat.Json, UriTemplate = "CPSendInfo")]
        int COSendTubeInfo(int LstData, out string ErrMsg);
//Service
        public int COSendTubeInfo(int LstData, out string ErrMsg)
        {
            ErrMsg = "Error";
            return 123;
        }
//Ajax Request



最好的问候,
