javascript - angularjs $http.get() 调用上的 catch() 不会抑制错误

Question

我有以下代码(为了示例而简化和running in codepen):

var app = angular.module("httptest", []);

app.controller("getjson", ["$scope", "$http", function($scope, $http) {
  $http.get("https://codepen.io/anon/pen/LVEwdw.js").
  then((response) => {
    console.log(response.data)
    console.log('in then')
    throw 'the error'
  }).catch((e) => {
    console.log('in the catch')
    console.log(e);
  });
}]);

我的期望是，如果输入 catch() block ，错误将不会显示在控制台中，除非明确记录(即，它不会显示为红色) 。然而，情况并非如此，红色错误消息打印到控制台，然后进入 catch() block 。我尝试设置an equivalent example here它不使用 AngularJS 的 $http，它的行为符合我的预期:

var promise1 = new Promise(function(resolve, reject) {
  resolve();
});

promise1.then((result) => {
  console.log('about to throw error')
  throw 'hey'
 }).catch(function(error) {
  console.log(error);
});

在此示例中，没有红色错误通过。

这里发生了什么，是否可以抑制 $http 情况下处理的错误？

随着 AngularJS 1.6 的发布，该行为已得到修复:

来自 GitHub 提交:

fix($q): treat thrown errors as regular rejections

Previously, errors thrown in a promise's onFulfilled or onRejected handlers were treated in a slightly different manner than regular rejections: They were passed to the $exceptionHandler() (in addition to being converted to rejections).
