在Chrome中，如何将JavaScript控制台输出获取到stdout/stderr [英] In Chrome, how can I get the javascript console output to stdout/stderr

问题描述

我使用的是Google Chrome浏览器，并且有一个页面可以将一些信息打印到Javascript控制台-我想将此内容通过管道传递给脚本.

I'm using Google Chrome, and have a page that prints some information to the Javascript console - I want to pipe this to a script.

我已经找到了如何在OS X上显示Chrome的标准输出的方法-通过在终端上运行以下命令(需要新的用户配置文件来确保该命令产生一个新的应用程序，否则我们将打开现有的应用程序并没有输出).

I've found how to display Chrome's stdout on OS X - by running the command below from a Terminal (a new user profile is needed to make sure the command spawns a new application, otherwise we'll open the existing one and get no output).

但是，我要打印到Terminal的只是内部Chrome信息.

However, all I'm getting printed to Terminal is internal Chrome information.

是否可以将所有JS控制台输出打印到stdout/stderr，以便将以下命令的输出通过管道传递到我的脚本?

Is there a way to get all JS console output to be printed to stdout/stderr so that I can pipe the output of the below command to my script?

TIA！

/Applications/Google \ Chrome.app/Contents/MacOS/Google \ Chrome --user-data-dir = temp-dir

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --user-data-dir=temp-dir

推荐答案

• 从命令行使用以下标志启用记录:

  --enable-logging --v=1

  这会记录Chrome内部所做的所有事情，但同时也会记录所有console.log()消息.日志文件名为 chrome_debug.log ，位于 User Data Directory .

  This logs everything Chrome does internally, but it also logs all the console.log() messages as well. The log file is called chrome_debug.log and is located in the User Data Directory.
