如何在Jquery和golang中使用输入的json数据进行ajax调用?

如何在Jquery和golang中使用输入的json数据进行ajax调用?,jquery,json,ajax,curl,go,Jquery,Json,Ajax,Curl,Go,我试图在Jquery中调用ajax,但得到的是空响应。但当我尝试通过卷曲做同样的事情时,我成功了。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

我试图在Jquery中调用ajax,但得到的是空响应。但当我尝试通过卷曲做同样的事情时,我成功了。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);
  }
});
我还尝试了
数据类型:“jsonp”
,但没有成功

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/
我有golang的服务器代码。我已经将标题设置为
访问控制允许标题:
。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,我在服务器端得到了空的请求主体。
有人能帮我吗?

您的数据已经在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);
      }
    });

问题是调用没有在body中发送请求数据[但不知何故,
curl
工作正常]。当我试图获取
主体时,err:=ioutil.ReadAll(r.body)
它给出了空值。所以我改成了从
r.Form

r.ParseForm()
var body []byte
for key, _ := range r.Form {
    body = []byte(key)
    break
}

r.Form
给出了一张地图。因此,我遍历映射并获取req数据。这就给出了解决办法。可能对其他人有帮助:)

我认为你不需要字符串化,你实际上是在字符串化2次,就像@Mir说的,
requestJSON
已经是一个string@slash197-我尝试不使用JSON.stringify,但没有帮助:(@slash197-我更新了问题,因为它重定向到了JSON.stringify问题。我更改了JSON.stringify(requestJSON)要从更新代码中请求JSON和Shappawoo,您需要stringfy
