保存storage_state信息

背景

使用playwright进行UI测试时，使用context.storage_state()保存若依CMS登录后的cookie信息失败，输出结果为空始终无法获取登录状态信息，但是断点调试又存在storage信息，这就很疑惑。

核心原因

playwright登录若依CMS时，成功后会跳转到/index页面。

但是playwright在确认登录成功后，就会关闭浏览器，而若依CMS会在跳转/index页面时，设置cookie等信息。

也就造成了我们获取不到cookie信息的原因。因此在后续代码中添加等待事件。page.wait_for_url()

输出storage信息

• print(storage)，cookie结果为null，但是打断点输出storage时，又有数据。

{'cookies': [], 'origins': []}

代码

原始代码，无法获取storage登录状态信息

import jsonfrom playwright.sync_api import Playwright, sync_playwrightdef run(playwright: Playwright) -> None:browser = playwright.chromium.launch(headless=False)context = browser.new_context()page = context.new_page()page.goto("http://81.70.166.221:8080/login")page.get_by_role("textbox", name="用户名").click()page.get_by_role("textbox", name="用户名").fill("admin")page.get_by_role("textbox", name="密码").click()page.get_by_role("textbox", name="密码").fill("admin123")page.get_by_role("button", name="登录").click()# page.pause()# 保存storage state 到指定的文件storage = context.storage_state(path='../auth/ry_auto.json')# ---------------------context.close()browser.close()with sync_playwright() as playwright:run(playwright)

改进后，添加等待事件wait_for_url

import jsonfrom playwright.sync_api import Playwright, sync_playwrightdef run(playwright: Playwright) -> None:browser = playwright.chromium.launch(headless=False)context = browser.new_context()page = context.new_page()page.goto("http://81.70.166.221:8080/login")page.get_by_role("textbox", name="用户名").click()page.get_by_role("textbox", name="用户名").fill("admin")page.get_by_role("textbox", name="密码").click()page.get_by_role("textbox", name="密码").fill("admin123")page.get_by_role("button", name="登录").click()# 等待时间，等待页面跳转，作为登录成功的标准page.wait_for_url(url='http://81.70.166.221:8080/index')# 添加断点# page.pause()# 保存storage state 到指定的文件storage = context.storage_state(path='../auth/ry_auto.json')print(storage)# ---------------------context.close()browser.close()with sync_playwright() as playwright:run(playwright)
