无法在 python selenium 脚本中使用带有特殊字符“$”的密码

Question

示例脚本：

\n\n

# -*- coding: utf-8 -*-\nfrom selenium import webdriver\nimport os\n\n#credentials\nUSERNAME = \'##########\'\nPASSWORD = \'#####$####\xe2\x80\x8b\'\n\n#load profile\nprofile = webdriver.FirefoxProfile()\nprofile.set_preference(\'browser.download.folderList\', 2)  # custom location\nprofile.set_preference(\'browser.download.manager.showWhenStarting\', False)\nprofile.set_preference(\'browser.download.dir\', os.getcwd())\n\n# following properties to suppress download popup screen\nprofile.set_preference("browser.helperApps.neverAsk.openFile", "text/csv")\nprofile.set_preference("browser.helperApps.neverAsk.saveToDisk", "text/csv")\n\n# initialise driver with above profile\ndriver = webdriver.Firefox(profile)\n\n\n#make the request to the url\ndriver.get(\'https://api.instagram.com/oauth/authorize/?client_id=#################&redirect_uri=#############&response_type=token\')\n#browser.current_url\ndriver.implicitly_wait(5)\n\n#Enter username and password\nUsername = driver.find_element_by_css_selector(\'#id_username\')\nUsername.send_keys(USERNAME)\n\nPassword = driver.find_element_by_css_selector(\'#id_password\')\nPassword.send_keys(PASSWORD)\n\n#SignIn button click\nSignIn = driver.find_element_by_css_selector(\'.button-green\').click()\n

正如你所看到的，我正在尝试验证 Instagram 应用程序。我无法传递具有特殊字符“$”的正确密码值。我收到以下错误。

\n\n

谁能帮我解决这个问题吗？\n提前致谢。

看起来字符串末尾有一个符号，无法对其进行编码

>>> PASSWORD.decode('utf-8')
u'#####$####\u200b'

你应该尝试删除它
