如何确定导致404错误的行？ [英] How can I determine what line is causing a 404 error?

问题描述

这个调用在JavaScript控制台中看起来像这样。

  GET some_path / undefined 404（未找到）
  

，它所有的权限就是：

  undefined：1 
  

它一遍又一遍地重复，它不会停止。如何确定哪个线路正在尝试拨打电话？

解决方案

在chrome上，您可以在XHR上添加断点，然后应该看到callstack。
转到开发人员工具 - >源选项卡 - >XHR断点，并添加相关URL过滤的断点

I have a terrible repeating error of 404 not found for a GET request.

The call looks like this in the JavaScript console

GET some_path/undefined 404 ( Not Found )

and all it states to the right of that is:

undefined:1

It keeps repeating over and over, it does not stop. How can I determine what line is trying to make this call?

解决方案

On chrome you can add breakpoints on XHR and then you should see the callstack. Go to developer tools -> "sources" tab -> "XHR Breakpoints" and add a breakpoint filtered by the relevant URL
