Question

// Ionic Starter App

// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
angular.module('starter', ['ionic'])

.run(function($ionicPlatform) {
  $ionicPlatform.ready(function() {
    if(window.cordova && window.cordova.plugins.Keyboard) {
      // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
      // for form inputs)
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);

      // Don't remove this line unless you know what you are doing. It stops the viewport
      // from snapping when text inputs are focused. Ionic handles this internally for
      // a much nicer keyboard experience.
      cordova.plugins.Keyboard.disableScroll(true);
    }
    if(window.StatusBar) {
      StatusBar.styleDefault();
    }
  });
})
.controller('AppCtrl', function($scope, $http) {
    $scope.data = {};
 
    $scope.submit = function(){
        var link = 'api_url';
 
        $http.post(link, angular.toJson({key: $scope.data.key,mac_address : $scope.data.mac_address})).then(function (res){
            $scope.response = res.data;
        });
    };
});

</html>

我使用了Json.stringfy，angulartojson等，但没有任何作用。我试图在localhost上运行此Api，并在api中给出所有访问控制头。 Api接受两个参数（post方法）将其保存到数据库并使用两个键返回json数据。 API无法获取这两个参数

要发帖，您必须具有以下结构：

.controller('AppCtrl', function($scope, $http) {

    $scope.submit = function(){
        var link = 'api_url';
        var data = {key: $scope.data.key, mac_address : $scope.data.mac_address};
        $http.post(method : 'POST', url : link, data : JSON.stringify(data), dataType : 'json', contentType: 'application/json')).then(function (res){
            $scope.response = res.data;
        });
    };
 });

感谢您的回答。实际上问题是我没有正确设置php api中的头部变量。我使用下面的代码解决了它。

    header("Access-Control-Allow-Origin: {$_SERVER['HTTP_ORIGIN']}");
    header('Access-Control-Allow-Credentials: true');
    header('Access-Control-Max-Age: 86400');    // cache for 1 day

无法将表单数据发布到离散的PHP API
