$ http.post不是一个函数

Question

我正在尝试将表单数据提交给我创建的API端点.我已经在PostMan中测试了它,并且API功能很好,我可以成功获取数据.但是当将该API端点连接到角度js中的函数时,我收到以下错误.

继承我的代码:

 $scope.saveSession = function() {

    $http.post("/session/survey", $scope.session).success(function(data, status) {
         $window.location.href = '/';

                console.log("Sucessfully getting data" + JSON.stringify(data));
    })
  }

注意:

$scope.session是使用ng-model标记填充的对象.例如:

<input type="text" ng-model="session.title">

编辑(控制器代码):

// This is our controller for the bio page
var session = angular.module('session', ['sessionService'])

session.controller('sessionCtrl', function($scope, $http, $window, sessionServices) {

$scope.session = {};

$scope.saveSession = function() {

    $scope.session.sessionNo = 1;
    $scope.session.coach = "mmmm";
    $scope.session.modules = "wokr place";

    //console.log(user);
    $http.post("/session/survey", $scope.session).success(function(data, status) {
         $window.location.href = '/';
                console.log("Sucessfully getting added bio" + JSON.stringify(data));
    })
    };

 });

Answer 1

那是因为.success()真的不是一个功能.正如文档所解释的那样$http.post(),您可以链接一个承诺.then()

$http.post('/someUrl', data, config).then(successCallback, errorCallback);

Answer 2

使用promises,$ http对象中不存在"success"函数($ http成功和错误方法仅在Angular 1.x的旧版本中可用,但它们已在Angular 1.6中删除):

// Simple GET request example:
$http({
  method: 'GET',
  url: '/someUrl'
}).then(function successCallback(response) {
    // this callback will be called asynchronously
    // when the response is available
  }, function errorCallback(response) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
});
