同一个程序开启多个浏览器

  1. from playwright.sync_api import sync_playwright
  3. # 全局变量（要注意，是整个环境全局变量，后续所有涉及playwright的浏览器创建都要基于改变量创建）
  4. playwright = sync_playwright().start()
  6. def get_context():
  7.   browser = playwright.chromium.launch(
  8.     executable_path="/Applications/Microsoft Edge.app/Contents/MacOS/Microsoft Edge",
  9.     headless=False,
  10.     args=["--disable-blink-features=AutomationControlled"],
  11.   )
  12.   context = browser.new_context(
  13.     bypass_csp=True,
  14.     viewport={"width": 1920, "height": 1080},
  15.   )
  16.   return context
  19. if __name__ == '__main__':
  20.   c1 = get_context()
  21.   c2 = get_context()
  22.   p1 = c1.new_page()
  23.   p1.goto('https://baidu.com')
  24.   print(p1.title())
  26.   p2 = c2.new_page()
  27.   p2.goto('https://baidu.com')
  28.   print(p2.title())
  30.   c1.browser.close()
  31.   c2.browser.close()

Django ORM 与 Playwright 一起使用

在没有经过设置的情况下，在django项目中使用playwright后，调用django orm会出现如下报错。
django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async.

解决的办法是在setting.py文件中，设置DJANGO_ALLOW_ASYNC_UNSAFE参数

  1. # 在setting.py文件中加入，即可解决
  2. import os
  3. os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true"
