登出网站无法正常工作。 / 如果网站没有加载关闭浏览器并重新打开

Question

所以我用 Python 编写了一个脚本，该脚本登录到一个帐户收集一些货币并注销，它会遍历很多帐户。它很容易成为用大量账户收集这种货币的脚本。问题是每次脚本需要注销时，它都会单击“注销”按钮，但如果它再次进入“注册”页面，它会说它仍然处于登录状态。顺便说一句，有时网站没有加载并且脚本只是自行关闭有人知道如何实现重新加载页面或重新打开 chromedriver 的功能吗？

脚本应该正常注销，没有任何问题，如果浏览器没有加载页面，浏览器就会关闭并重新打开。

您的代码块似乎接近完美。当您尝试将字符序列发送到所需字段时，您需要使用element_to_be_clickable()，而不是使用visibility_of() 的expected_conditions，如下所示：

print("Trieng to connect to Palai.org")
browser.get('https://www.palai.org/u/sign_in')
# WebDriverWait(browser, 10).until(EC.title_contains("Log in – Palai (beta)"))
print("Successfully connected to Palai.org!")

print("Trieng to Log into the Account: ", l)
WebDriverWait(browser, 20).until(EC.element_to_be_clickable((By.ID, "user_email"))).send_keys(l)
browser.find_element_by_id("user_password").send_keys("mypassword")
browser.find_element_by_name('commit').click()
print("Successfully logged in!")
