请记住，$ q.all将在第一次拒绝后退出，如果您要确保所有承诺均已结束(已解决或被拒绝)，则可以使用角度承诺附加模块( https://github.com/ohjames/angular-promise-extras)其$ q.allSettled方法.因此，您可以将pwolaq不错的答案中的$ q.all()替换为:

keep in mind that $q.all will exit after first reject, if you want to be sure that all promises ended (resolved or rejected), you may use angular promise extras module (https://github.com/ohjames/angular-promise-extras) whith its $q.allSettled method. So you can just replace $q.all() in pwolaq's nice answer with:

$q.allSettled (promises);
