如何在 AngularJS 中使用 axios 库 [英] How to use the axios library with AngularJS
问题描述
我在 axios 库" rel="nofollow noreferrer">angularjs 当我看到 axios 回调中 $scope
的变化被 angular 检测到时,我感到很惊讶.我想我必须像使用 setTimeout
一样调用 $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)
你知道为什么 axios 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,所以我猜 $http
触发的摘要循环正在帮助 axios 回调被消化";
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<将其 ES6 承诺带入 AngularJS 上下文/a>:
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会受益于 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 而不是 setTimeout代码>.
$timeout(() => {
$scope.timeoutResult = {message: "timeout!"});
}, 2000)
$timeout 服务与 AngularJS 框架及其消化循环.
The $timeout service is integrated with the AngularJS framework and its digest cycle.
