python+playwright 学习-85 启动参数 proxy 设置代理几种方式

前言

在使用playwright执行代码的时候，如需设置代理，可以在启动的时候加proxy 参数设置代理。
本篇总结下可以加proxy代理的几种方式。

launch 启动全局代理

launch 启动的时候设置全局代理，以下是示例

from playwright.sync_api import Playwright, sync_playwright

with sync_playwright() as playwright:
    browser = playwright.chromium.launch(
        headless=False, proxy={"server": "http://myproxy.com:3128"}
    )
    context = browser.new_context()

    page = context.new_page()
    page.goto('http://47.108.155.10/login.html')

    browser.close()

proxy 参数说明

proxy 传 dict 类型，可以设置的参数有

• server 例如，支持HTTP和SOCKS代理http://myproxy.com:3128或socks5://myproxy.com:3128。缩写myproxy.com:3128被认为是HTTP代理
• bypass 可选，逗号分隔域以绕过代理，例如“.com、chromium.org、.domain.com”。
• username 可选，如果HTTP代理需要身份验证，则使用用户名。
• password 可选，如果HTTP代理需要身份验证，则使用密码。

带账号密码的代理示例

from playwright.sync_api import Playwright, sync_playwright

with sync_playwright() as playwright:
    browser = playwright.chromium.launch(
        headless=False, proxy={
            "server": "http://myproxy.com:3128",
            'username': 'p-username',  # 需要身份验证，可以通过这里指定用户名和密码
            'password': 'p-password'
        }
    )

对于Windows上的Chromium，浏览器需要使用全局代理才能运行此选项。如果所有上下文都覆盖代理，则全局代理将永远不会使用，并且可以是任何字符串，例如launch（｛proxy:｛server:'http://per-context“｝｝”）。

context上下文设置代理

对于Windows上的Chromium，浏览器需要launch设置全局代理才能运行此选项。
如果上下文也设置了proxy代理，会覆盖launch设置全局代理。

from playwright.sync_api import Playwright, sync_playwright
# 作者-上海悠悠 微信/QQ交流:283340479
# blog地址 https://www.cnblogs.com/yoyoketang/

with sync_playwright() as playwright:
    browser = playwright.chromium.launch(
        headless=False, proxy={
            "server": "http://myproxy.com:3128",
            'username': 'p-username',  # 需要身份验证，可以通过这里指定用户名和密码
            'password': 'p-password'
        }
    )
    context = browser.new_context(proxy={
        'server': 'http://127.0.0.1:8888'
    })
    page = context.new_page()
    page.goto('http://47.108.155.10/login.html')

对于firefox 和 webkit 系列浏览器，可以不用在launch设置proxy

from playwright.sync_api import Playwright, sync_playwright


with sync_playwright() as playwright:
    browser = playwright.firefox.launch(headless=False)
    context = browser.new_context(proxy={
        'server': 'http://127.0.0.1:8888'
    })
    page = context.new_page()
    page.goto('http://47.108.155.10/login.html')

new_page() 设置代理

基于 context 创建的的new_page() 没有proxy参数设置

    context = browser.new_context()
    page = context.new_page()

基于browser 创建的new_page() 有proxy参数设置

from playwright.sync_api import Playwright, sync_playwright


with sync_playwright() as playwright:
    browser = playwright.firefox.launch(headless=False)

    page = browser.new_page(proxy={'server': 'http://127.0.0.1:8888'})
    page.goto('http://47.108.155.10/login.html')

非无痕模式启动浏览器launch_persistent_context

非无痕模式启动浏览器只能在launch_persistent_context()添加proxy参数

from playwright.sync_api import Playwright, sync_playwright
# 作者-上海悠悠 微信/QQ交流:283340479
# blog地址 https://www.cnblogs.com/yoyoketang/

with sync_playwright() as playwright:
    context = playwright.chromium.launch_persistent_context(
        # 指定本机用户缓存地址
        user_data_dir=f"D:\chrome_userx\yoyo",
        headless=False,
        proxy={
            'server': 'http://127.0.0.1:8888'
        }
    )
    page = context.pages[0]
    page.goto('http://47.108.155.10/login.html')
