将信息从命令行传递到Chrome扩展 [英] Passing information from command line into Chrome extension
问题描述
我希望能够在某些情况下更改我的Chrome扩展程序的行为。我控制Chrome的启动,以便我可以添加任何命令行标志到实现这一点(最好不要改变Chrome的行为)。
我需要这些信息在扩展的后台页面(而不是内容页面)中可用。
我想到的一件事是添加一个环境变量,但显然这是 我试图通过命令行切换到< href =https://code.google.com/p/chromium/codesearch#chromium/src/chrome/common/chrome_switches.cc =nofollow noreferrer> Chromium的代码
test-name
。
test-name
在扩展中可用?如果没有,是否有另一种方法将信息传递给Chrome扩展?
无法将信息直接发送到扩展。
您需要以这种或那种方式使用消息传递功能。 例如,您可以使用 Chrome原生消息与Python脚本进行通信。 或者您可以使用网络信息
a>从网页发布消息(可能是一个file:// URL)。
- 您可以尝试 selenium 直接执行脚本。
from selenium import webdriver
driver = webdriver.Chrome('/ path / to / chromedriver')
driver.get('file:///some/page.html')
driver.execute_script('chrome.runtime.sendMessage( ')
driver.quit()
- 另一个扩展可以为您处理消息。 >
I want to be able to change the behaviour of my Chrome extension in certain cases. I control the launch of Chrome so I can add any command line flag to achieve this (preferably not one that changes the behaviour of Chrome).
I need this information to be available in the background page of the extension (not in content pages).
One thing I thought of was adding an environment variable, but apparently this isn't directly available from the extensions context.
I tried looking through the command line switches in Chromium's code and thought I may be able to use test-name
.
Is the test-name
available in the extension? If not is there another way to pass information into a chrome extension?
There is no way to send information to an extension directly.
You need to use messaging one way or another.
You could use Chrome Native Messaging to communicate with a python script for example.
Or you could use web messaging to post a message from a web page (which could be a file:// URL).
- You could try selenium to execute the script directly.
from selenium import webdriver
driver = webdriver.Chrome('/path/to/chromedriver')
driver.get('file:///some/page.html')
driver.execute_script('chrome.runtime.sendMessage("extensionID", "message");')
driver.quit()
- Another extension could take care of the messaging for you.
