前言

 现在越来越多的文章都在说playwright在自动化方面比selenium更加的具有优势，而且我看现在大多数公司的招聘也要求掌握playwright，所以有必要对该工具的使用进行掌握，并作一些详细的记录。在这里我并不会对两个工具进行比较，我始终相信，工具本身并无强弱之分，只在使用场景的是否合适。

环境搭建

 本次虚拟环境使用uv来进行解释器的管理与环境的管理。

1. 选择合适的解释器版本创建项目

bash
uv python list  # 查看解释器列表
>>>
cpython-3.14.0rc3-macos-x86_64-none                 <download available>
cpython-3.14.0rc3+freethreaded-macos-x86_64-none    <download available>
cpython-3.13.7-macos-x86_64-none                    <download available>
cpython-3.13.7+freethreaded-macos-x86_64-none       <download available>
cpython-3.13.4-macos-x86_64-none                    /Users/jingwei/.pyenv/shims/python3.13
cpython-3.13.4-macos-x86_64-none                    /Users/jingwei/.pyenv/shims/python3
cpython-3.13.4-macos-x86_64-none                    /Users/jingwei/.pyenv/shims/python

uv init KTP --python 3.13  # 选择解释器初始化项目
>>>
Initialized project `ktp` at `/Library/PyLearning/KTP`

2. 在项目目录中创建虚拟环境

bash
% cd KTP
% uv venv --python 3.13 # 创建虚拟环境
% source .venv/bin/activate  # 激活虚拟环境
% tree -a -L 2  # 查看目录结构
.
├── .idea
│   ├── .gitignore
│   ├── inspectionProfiles
│   ├── KTP.iml
│   ├── misc.xml
│   ├── modules.xml
│   ├── vcs.xml
│   └── workspace.xml
├── .python-version

│   ├── CACHEDIR.TAG
│   ├── include

├── main.py

3. pycharm编译器解释器的配置

打开pycharm >> 设置... >> Python >> 解释器

playwright的安装与demo编写

1. playwright 与 Chromium安装

 playwright需要下载单独的浏览器，以确保自动化运行的可靠性、一致性和可维护性。

bash
uv add playwright  # 安装 playwright
uv pip show playwright  # 查看playwright的安装的详情
>>>
Name: playwright
Version: 1.58.0
Location: /Library/PyLearning/KTP/.venv/lib/python3.13/site-packages
Requires: greenlet, pyee
Required-by:

uv run playwright install chromium  # 安装浏览器，安装的位置在全局的缓存目录中，来实现多项目的共享。
ls /Users/jingwei/Library/Caches/ms-playwright/  # 查看安装的看浏览器

2. demo编写

python
from playwright.sync_api import sync_playwright

with sync_playwright() as p:
    browser = p.chromium.launch(headless=False)
    page = browser.new_page()
    page.goto("https://www.google.com")
    print("the page title is {}".format(page.title()))
    browser.close()
