angular.js:14642 TypeError: Cannot read property 'then' of undefined when calling back-end service from angular

Question

我正在使用 angular 调用后端服务，但遇到错误。响应到达我的服务，但由于上述承诺错误，我无法从那里获得对我的 angular 控制器的响应。

angular 服务

function userRegister(data) {
  $http.post('/api/user/register',data).then(function(response) {
    console.log(response); //the success response comes here
    return response;
  });
}

angular 控制器

vm.register = function register() {
  console.log(vm.user);

  commonService.userRegister(vm.user).then(function (response) {
    console.log(response); //the promise error comes here
  });
}

有人可以帮我解决这个问题吗？

你应该 return 你的服务也

function userRegister(data) {
 return $http.post('/api/user/register',data).then(function(response) {
    console.log(response); //the success response comes here
    return response;
  });
}
