我正在嘗試在 Jquery 中進行 ajax 調用，但收到空響應。但是當我嘗試通過 curl 做同樣的事情時，我成功了。這是我的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); }});我也試過，dataType: "jsonp"但沒有運氣。curl 命令在這里，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 中有服務器代碼。我已經將標題設置為Access-Control-Allow-Headers:*. 這是我的服務器處理程序。 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()) }具體來說，我在服務器端收到空請求正文。有人可以幫我嗎？

問題是調用沒有在正文中發送請求數據 [但不知何故curl工作正常]。當我嘗試獲取body, err := ioutil.ReadAll(r.Body)它時，它給出了空值。所以我改變了從r.Form
r.ParseForm()
var body []byte
for key, _ := range r.Form {
body = []byte(key)
break
}
r.Form給一張地圖。所以我正在遍歷地圖并獲取 req 數據。這個SO帖子給出了解決方案。可能對其他人有幫助:)

您的數據已在 console.log 中字符串化
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);
}
});
