Hey there! Let's break down your two questions about automating Chrome shutdown step by step:

一、是否可以编写程序退出Chrome浏览器？ #

Absolutely yes! How you do it depends on your operating system, but there are straightforward ways to kill Chrome's process(es) using scripts or code. Here are some common implementations:

Windows 平台 #

You can use the built-in taskkill command, or wrap it in a Python script for more flexibility:

• 批处理脚本（close_chrome.bat）：

@echo off
taskkill /f /im chrome.exe

• Python 脚本：

import subprocess

subprocess.run(["taskkill", "/f", "/im", "chrome.exe"], check=True)

macOS/Linux 平台 #

Use pkill to target Chrome's process. Note that on macOS, the process name is Google Chrome, while on most Linux distros it's chrome:

• Shell 脚本（close_chrome.sh）：

# macOS
pkill "Google Chrome"

# Linux
pkill chrome

• Python 脚本：

import subprocess
import platform

if platform.system() == "Darwin":
    subprocess.run(["pkill", "Google Chrome"], check=True)
elif platform.system() == "Linux":
    subprocess.run(["pkill", "chrome"], check=True)

注意事项：

• The /f flag (Windows) forces Chrome to close immediately, bypassing any "save tabs" prompts. Omit it if you want Chrome to show the prompt first.
• On macOS/Linux, if Chrome has multiple processes (it usually does), pkill will terminate all of them.

二、访问指定网站后自动关闭Chrome，是否可行？ #

This is totally doable too! The most reliable way is to build a Chrome Extension (using Manifest V3, the latest standard) that monitors your active tabs and triggers a shutdown when the target URL is detected. Here's a quick example:

Step 1: Create the extension files #

First, make a new folder and add two files:

manifest.json (required for all Chrome extensions)

This defines permissions and basic info:

{
  "manifest_version": 3,
  "name": "Auto-Close Chrome on Target Site",
  "version": "1.0",
  "permissions": ["tabs", "windows"],
  "background": {
    "service_worker": "background.js"
  }
}

background.js (the logic to monitor tabs)

This script listens for tab updates and closes Chrome when the target URL matches:

// Replace this with your target website URL (can use wildcards)
const TARGET_URL = "*://example.com/*";

chrome.tabs.onUpdated.addListener((tabId, changeInfo, tab) => {
  // Check if the tab's URL matches our target and the page is fully loaded
  if (changeInfo.status === "complete" && tab.url.match(new RegExp(TARGET_URL.replace(/\*/g, ".*")))) {
    // Close the current Chrome window (this will shut down Chrome if it's the only window)
    chrome.windows.getCurrent({ populate: false }, (window) => {
      chrome.windows.remove(window.id);
    });
  }
});

Step 2: Load the extension into Chrome #

1. Open Chrome and go to chrome://extensions/
2. Enable "Developer mode" (toggle in the top-right corner)
3. Click "Load unpacked" and select your extension folder

注意事项：

• If you want to close Chrome even if there are multiple windows, replace the chrome.windows.remove call with a method to terminate all windows (loop through chrome.windows.getAll and remove each one).
• The wildcard * in TARGET_URL lets you match subpages (e.g., *://example.com/blog/* will match any blog post on example.com).
