为什么Ember.onerror（）没有捕获Assertion Failed错误。 [英] Why Ember.onerror() not capturing the Assertion Failed error.?

问题描述

我的代码中有一个情况，我需要跟踪我的生产中的错误。

I have a situation in my code where i need to trace the errors in my production.

我使用 ember.js 作为我的框架。

I used ember.js as my framework.

为了跟踪生产中出现的错误，我使用了 Ember.Onerror ，它只提供了任何功能错误跟踪。 / p>

To trace the errors occuring in production i used Ember.Onerror which provides me only any functionality error trace.

Ember.onerror = function(error) {
  Em.$.ajax('/error-notification', 'POST', {
    stack: error.stack,
    otherInformation: 'exception message'
  });
}

但是我想追踪断言失败的错误，例如

But i would like to trace the assertion failed errors for example

URL * 没有匹配应用程序中的任何路由器 *

The URL * didnot match any of the routers in your application*

推荐答案

Ember关于捕获错误和断言错误的文档确实很少。在我的情况下，在进行生产之前，我需要在调试模式下将控制台之外的这些异常可视化。所以，我去了GitHub的Ember项目，发现Ember.onerror（错误）{...}和Ember.assert（desc，test）{...}函数的规范和实现，然后我写了我的自己的这些函数内部的一个新的适配器（app / initializers文件夹）的初始化函数，我决定命名errorHandler。

There is really few documentation on Ember about catching errors and assertions errors. In my case, I needed to visualize these exceptions beyond the console in my debug mode, before going into production. So, I went to the Ember project in GitHub and found the specification and implementation for the Ember.onerror(error) {...} and Ember.assert(desc, test) {...} functions and then I just wrote my own version of these functions inside the initialize function of a new adapter (app/initializers folder) that I decided to name errorHandler.

Ember.assert = function(desc, test) {
    if (!test) {
        console.log('This is a test to log Assertions!');
        /* your assertion treatment code goes here*/
        throw new Ember.Error("Assertion Failed: " + desc);
    }
}

...并抛出新的Ember.Error （...）你实际上是在调用：

...and by throwing that new Ember.Error(...) you are actually calling:

Ember.onerror = function(error) {
    console.log("An error has occurred in ember: " + error.message);
    /* your error treatment code goes here*/
};
