AngularJS - 使用ngMockE2E $ httpBackend我怎么能延迟特定的响应？ [英] AngularJS - Using ngMockE2E $httpBackend how can I delay a specific response?

问题描述

我想推迟以下whenGET响应：

I'd like to delay the response to the following whenGET:

$httpBackend.whenGET(/^foobar/).respond(function () {
  return [200,{}];
});

不过这似乎是不可能使用$超时同步做到这一点，所以我不知道如何处理呢？

However it seems impossible using $timeout to do this synchronously, so I'm not sure how to approach this?

推荐答案

如果你想拖延只是一个具体的回应，可能比你耽误范围财产效应初探转让。

If you want to delay only a specific response, than you may delay assignment of the reponse to scope property.

如果你换你的电话到您的自定义服务方法，可能比你的包裹到响应的承诺，并在需要的时候解决这个问题：

If you wrap your call into your custom service method, than you may wrap the response into the promise and resolve it when needed:

JS：

angular.module('app').service('myService', function($q, $timeout){

 this.getData = function() {
    var delay = 300,
        origPromise = $http.get('someUrl'),
        deferred = $q.defer();
    $timeout(function() {
       deferred.resolve(origPromise);
    }, delay);

    return defered.promise;
 };

});

要延迟设置为所有的请求，你可以申请这个解决方案的响应拦截

To set the delay to all requests, you may apply this solution to the response interceptor
