保存登录与剧作家

Question

我试图保存我的登录与剧作家，我已经阅读了文档，并试图实现它到我的代码，但我仍然得到错误

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=False, slow_mo=50)
page = context.new_page()
page.fill("input#input-username", "demo")
page.fill("input#input-password", "demo")
page.click("button[type=submit]")
context = browser.new_context(storage_state="website1.json")
storage = context.storage_state(path="website1.json")

page = context.new_page()

NameError: name 'context' is not defined

超级困惑。

Answer 1

主要问题:

context.new_page()变量声明前调用(context = ...)

应该可以正常工作:

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=False, slow_mo=50)
context = browser.new_context(storage_state="website1.json")
page = context.new_page()
page.goto('https://demo.opencart.com/admin')
page.fill("input#input-username", "demo")
page.fill("input#input-password", "demo")
page.click("button[type=submit]")

也可以使用持久身份验证:

from playwright.sync_api import sync_playwright
with sync_playwright() as p:
user_data_dir = 'FULL_PATH_TO_BROWSER_PROFILE'
browser = p.chromium.launch_persistent_context(user_data_dir, headless=False)
# login only 1 time...

JFYI:opencart在GET参数中使用user_token并对其进行验证。playwright(storage_state,user_data_dir等)应该工作良好。例子:

# run docker container with playwright
docker rm -fv example && docker run --name example -it mcr.microsoft.com/playwright/python:v1.27.1-focal bash
# create empty state
echo {} >> /tmp/state.json
# run python in interactive mode
python
# Python 3.8.10 (default, Jun 22 2022, 20:18:18) 
# [GCC 9.4.0] on linux
# Type "help", "copyright", "credits" or "license" for more information.

粘贴下一个脚本:

from time import sleep
from urllib.parse import parse_qs
from playwright.sync_api import sync_playwright
with sync_playwright() as p:
# login
browser = p.chromium.launch()
context = browser.new_context(storage_state='/tmp/state.json')
page = context.new_page()
page.goto('https://demo.opencart.com/admin')
page.fill('input#input-username', 'demo')
page.fill('input#input-password', 'demo')
page.click('button[type=submit]')
sleep(5)  # just wait for redirect - you can wait for a element...
page.context.storage_state(path='/tmp/state.json')
page.screenshot(path='/tmp/after_state_init.png')
# parse user_token for GET requests
parsed_url = parse_qs(page.url)
user_token = parsed_url['user_token'][0]
print(f'user token {user_token}')
page.close()
browser.close()

with sync_playwright() as p:
# open admin dashboard without login... 
browser = p.chromium.launch()
context = browser.new_context()
page = browser.new_page(storage_state='/tmp/state.json')
page.goto(f'https://demo.opencart.com/admin/index.php?route=common/dashboard&user_token={user_token}')
sleep(5)
page.screenshot(path='/tmp/open_using_saved_state.png')
page.close()
browser.close()

现在打开一个新的终端，从docker容器复制屏幕:

docker cp example:/tmp/after_state_init.png ./
docker cp example:/tmp/open_using_saved_state.png ./

你会看到它们是相同的-管理仪表板不需要登录。
