javascript - .getAll(...).then 不是一个函数

Question

我将 Angular 更新到版本 1.6.4。所以我必须将 .success 和 .error 更新为 .then

现在我收到以下错误:

TypeError: .getAll(...).then is not a function

问题出在服务中:

    function getAll(page, size) {
    return $http.get(baseUrl + '/jobprofiles?page='+page+'&size='+size, {timeout: 5000}).then(function (response) {
      data = response;
    }), (function(response) {
      alertService.setAlert({'message': 'jobmatch.server.unavailable', 'classified': 'danger', 'lives':1});
    });
  }

这是 Controller :

    if($cookies.get("authenticated")=='true'){
    //get a list of all candidateprofiles with the use of a page and a size
    candidateprofilesService.getAll($scope.page, $scope.size).then(function() {
      $scope.data = candidateprofilesService.getData()._embedded.candidateprofiles;
      candidateprofilesService.getAll($scope.page, $scope.size+10).then(function() {
        if(candidateprofilesService.getData()._embedded.candidateprofiles.length > $scope.data.length){
          $scope.moreData = true;
        }
        else {
          $scope.moreData = false;
        }
      })
    });
  }

您的服务代码应该是这样的:

myApp.service('candidateprofilesService', function($http) {
     this.getAll = function (page, size) {
        // just return the promise , don't evaluate here
        return $http.get(baseUrl + '/jobprofiles?page='+page+'&size='+size, {timeout: 5000});
   }    

   this.getData = function(){
      // your getData() method body, also just return the promise.
   }
});

然后在注入(inject)服务后在 Controller 中，

 candidateprofilesService.getAll($scope.page, $scope.size).then(function(response){
      //Evaluate promise here and handle the response
    }, function(error){
         //handle error
 });
