如何在AngularJS中使用axios库 [英] How to use the axios library with AngularJS

问题描述

我正在 axios 库"rel ="nofollow noreferrer"> angularjs ，当我看到axios回调中对$scope的更改被angular检测到时，我感到很惊讶.我以为我必须像在使用setTimeout时那样调用$apply.

I was trying axios library on angularjs and I was surprised when I saw that the changes to $scope in the axios callback were detected by angular. I thought I had to call $apply like, for example, when you use setTimeout.

  // axios example
  axios.get(url).then((response) => {
    // Here I don't need $apply, why??
    $scope.axiosResult = response.data;
  });


  // setTimeout example
  setTimeout(() => {
    // Here I need $apply for the timeoutResult to appear on the HTML
    $scope.$apply(() => $scope.timeoutResult = {message: "timeout!"});
  }, 2000)

您知道为什么axios中不需要$apply吗?

Do you know why $apply is not needed in axios?

georgeawg的评论帮助我看到我正在使用$http在另一个地方，所以我想由$http触发的摘要周期正在帮助axios回调被消化".也是.

A comment by georgeawg helped me see that I was using $http on another place, so I guess the digest cycle triggered by $http is helping axios callback to be "digested" too.

如何使用 axios库使用AngularJS

使用 $ q.when :

How to use the axios library with AngularJS

Bring its ES6 promises into the AngularJS context using $q.when:

  // axios example
  ̶a̶x̶i̶o̶s̶.̶g̶e̶t̶(̶u̶r̶l̶)̶.̶t̶h̶e̶n̶(̶(̶r̶e̶s̶p̶o̶n̶s̶e̶)̶ ̶=̶>̶ ̶{̶
  $q.when(axios.get(url)).then((response) => {
    $scope.axiosResult = response.data;
  });

只有在AngularJS执行上下文中应用的操作才能受益于AngularJS数据绑定，异常处理，属性监视等.

Only operations which are applied in the AngularJS execution context will benefit from AngularJS data-binding, exception handling, property watching, etc.

还使用 $ timeout服务代替setTimeout.

  $timeout(() => {
    $scope.timeoutResult = {message: "timeout!"});
  }, 2000)

$ timeout 服务已与AngularJS框架及其集成消化周期.

The $timeout service is integrated with the AngularJS framework and its digest cycle.
