在Angular2定义异常处理程序

问题描述

在angular2例外记录在默认情况下，控制台。我听说我们可以继承角的ExceptionHandler，创造我们自己的异常处理程序，使我们可以覆盖默认行为。我试着做，但没有奏效。谁能帮我在这一个例子。在此先感谢....

In angular2 the exceptions are logged in the console by default. I heard that we can inherit the Angular ExceptionHandler and create our own exception handler so that we can override the default behavior. I tried to do it but didn't work. Can anyone help me on this with an example. Thanks in advance ....

推荐答案

看起来你需要创建自己的类来处理异常，然后在您的应用程序在引导时绑定的，是这样的：

It looks like you need to create your own class to handle exceptions, and then bind it in your app at bootstrap time, something like this:

class MyExceptionHandler implements ExceptionHandler {
    call(error, stackTrace = null, reason = null) {
       // do something with the exception
    }
 }

然后在引导时，绑定这个新的实施作为的ExceptionHandler：

And then at bootstrap time, bind this new implementation as the ExceptionHandler:

bootstrap(MyApp, [bind(ExceptionHandler).toClass(MyExceptionHandler)])
