我想提交信息給在線服務器,它要求我使用FormData發送信息。 所以我用下面的函數,該函數
var my_app = angular.module("my-app",[])
my_app.controller("MainController", function($scope, $http){
$scope.master = {title: "Title",desc: "Desctibe", tags: ["One","Two"], category: ["1","2"] };
var url = "http://freedoctor.southeastasia.cloudapp.azure.com/api/forum/create";
var config = {"headers":{"Authorization":"JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6IjU5MzEwNDUxZjk3MjJmZTQyODE1NTIxYSIsInJvbGUiOiJwYXRpZW50IiwiaWF0IjoxNDk3NDE4ODA3fQ.ODrSlYwxvrPb93IzHW3s-7NIVFsOL4pKzqZx8yMqWWE"}};
$scope.booking = function(){
$scope.title=$scope.user.title;
$scope.desc=$scope.user.desc;
$scope.tags=$scope.user.tags;
$scope.category=$scope.user.category;
$scope.askedTo=$scope.user.askedTo;
var info = new FormData();
info.append("title", $scope.title);
info.append("desc", $scope.desc);
info.append("tags", $scope.tags);
info.append("category", $scope.category);
$http.post("http://localhost:8080/"+url, info, config).then(
function(response){
console.log(response);
$scope.reply = response.data;
},
function(response){
console.log(response);
$scope.reply = response.data;
});
}
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
});
所以每當我撥打預訂功能,我得到一個內部服務器錯誤
SyntaxError: Unexpected token -

我知道FORMDATA工作,因爲我這個
檢查出來for (var pair of info.entries()) {
console.log(pair[0]+ ', ' + pair[1]);
}
我回答了類似的問題https://stackoverflow.com/questions/44405200/unable-to-loop-through-string-array-and-append-to-formdata/44405713#44405713。可能是你可以以某種方式與它聯繫 –
感謝您的回答,但我不認爲這將適用於我的情況。因爲我只想在請求中發送字符串。 我只是無法理解我撥打電話後收到的錯誤 –
我看到您正在嘗試將自定義屬性添加到FormData對象。我懷疑這不被支持,因此你的請求不能被序列化。 –
