jquery - 如何在Jquery和golang中使用输入的json数据进行ajax调用？

我正在尝试在Jquery中进行ajax调用，但响应却空了。但是，当我尝试通过卷曲做同样的事情时，我就成功了。这是我的JS，

time = new Date($.now());
requestJSON = '{"Method":"GET","AppName":"Proline","ServiceURL":"http://localhost:8081/api/services/tags/","Properties":null,"Object":"","Timestamp":"'+time+'"}'
$.ajax({
  type: "GET",
  url: "http://localhost:8081/api/services/tags/",
  // The key needs to match your method's input parameter (case-sensitive).
  data: requestJSON,
  contentType: "application/json; charset=utf-8",
  dataType: "json",
  success: function(data){alert(data);},
  failure: function(errMsg) {
      alert(errMsg);
  }
});

我也尝试过dataType: "jsonp"，但是没有运气。

curl命令在这里，

curl --data '{"Method":"GET","AppName":"Proline","ServiceURL":"http://localhost:8081/api/services/tags/","Properties":null,"Object":"","Timestamp":"2016:03:27 00:08:11"}'
-X GET http://localhost:8081/api/services/tags/

我在golang中有服务器代码。我已经将标题设置为Access-Control-Allow-Headers:*。这是我的服务器处理程序。

 func tagsHandler(w http.ResponseWriter, r *http.Request, extra []string) {
    if origin := r.Header.Get("Origin"); origin != "" {
            w.Header().Set("Access-Control-Allow-Origin", origin)
            w.Header().Set("Access-Control-Allow-Methods", "POST, GET, OPTIONS, PUT, DELETE")
            w.Header().Set("Access-Control-Allow-Headers",
                    "*")
    }
    // Stop here if its Preflighted OPTIONS request
    if r.Method == "OPTIONS" {
            return
    }
    var response []byte
    body, err := ioutil.ReadAll(r.Body)
    if err != nil {
        log.Printf("FATAL IO reader issue %s ", err.Error())
    }
    log.Printf("Body : %s ", string(body))
    method    := r.Method
    log.Printf("tagsHandler() :: service method %s ", method)
    if method == HTTP_VERB_POST {
                response = tagslogic.PostTag(body)
    } else if method == HTTP_VERB_GET {
                response = tagslogic.GetTags(body)
    } else if method == HTTP_VERB_PUT {
                response = tagslogic.PutTag(body)
    } else if method == HTTP_VERB_DEL {
            response = tagslogic.DelTag(body)
        }
    w.Write(response)
}

具体来说，我正在服务器端获取空的请求正文。
有人可以帮我吗？

最佳答案

您的数据已在console.log中进行了字符串化

 time = new Date($.now());
    requestJSON = '{"Method":"GET","AppName":"Proline","ServiceURL":"http://localhost:8081/api/services/tags/","Properties":null,"Object":"","Timestamp":"'+time+'"}'
    $.ajax({
      type: "GET",
      url: "http://localhost:8081/api/services/tags/",
      data:JSON.stringify(requestJSON),
      contentType: "application/json; charset=utf-8",
      dataType: "json",
      success: function(data){alert(data);},
      failure: function(errMsg) {
          alert(errMsg);
      }
    });
