有没有办法解析 python-flask oauth2

[英]is there a way to parse python-flask oauth2

我有类似下面的代码 -

app = Flask(__name__)


# access token
access_token = None


@app.route('/getcode')
def get_authorization_url():
    oauth = OAuth2Session(client_id, redirect_uri=redirect_uri, scope=scope)
    authorization_url, _state = oauth.authorization_url(authorization_base_url, access_type="authorization_code")
    print('authorization_url')
    print(authorization_url)
    return redirect(authorization_url)


@app.route('/')
def callback():
    global access_token
    oauth = OAuth2Session(client_id, redirect_uri=redirect_uri, scope=scope)
    token = oauth.fetch_token(token_url, authorization_response=request.url, client_secret=client_secret)
    access_token = token['access_token']
    print('access token is:', access_token)

    ## we will be shutting down the server after getting access_token
    ## the thread created here is copied in if __name__ == '__main__' block
    ## and will run after closing the server

    # th = threading.Thread(target=data_from_resource_server, args=(access_token,))
    # th.start()

    func = request.environ.get('werkzeug.server.shutdown')
    if func:
        print('stoping server')
        func()


    return 'see terminal for logs'


if __name__ == '__main__':
    app.secret_key = 'example'
    app.env = 'development'
    print()
    print('Open this url in browser:', 'http://127.0.0.1/getcode', end='\n\n')

    app.run(host='127.0.0.1', port='80')

    print('server stopped')

    ## got access_token, closed the server, now running ray integration code
    if access_token:
        th = threading.Thread(target=data_from_resource_server, args=(access_token,))
        th.start()

这里当 app.run(host='127.0.0.1', port='80') 运行时给我 URL - http://127.0.0.1/getcode 我需要手动打开输入用户名和密码,然后再输入一个 window 进入 YOB,然后给我类似的东西 -

127.0.0.1 - - [04/May/2021 21:20:23] "GET /**getcode?code=G7h_QL0Cpo3kEqyyNBZ68DTX3JhQ_6E6sl_Sk1x5iBc.oG4JFQiKyZGupTuJ-bV6qE9lA**&scope=orders&state=M6hdb7EJxgNKkuBqbihg1SKaUGAJ7W HTTP/1.1" 302  

在这里我的问题是有一种方法可以避免手动打开浏览器并输入凭据并获取代码。 我们可以在 python 中解析整个内容吗?

听起来像是 Selenium 的工作。 它可以打开 web 浏览器并为您解析所需的详细信息。

启动服务器后运行以下代码

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

url = 'http://127.0.0.1/getcode'
driver = webdriver.Firefox()  # (Or Chrome())
driver.get(url)

username = driver.find_element_by_id("username")
password = driver.find_element_by_id("password")

# uncomment this code if your text boxes have pre-populated text
#username.clear()
#password.clear()

username.send_keys("YourUsername") # change this to your username
password.send_keys("PassworD")     # change this to your password
driver.find_element_by_name("submit").click()

# we can implicitly wait before the page loads
driver.implicitly_wait(2)

现在,这将处理您问题的第一部分,即自动化登录过程。 现在我不确定你的下一个目标是什么,但我假设你想要 URL 中的代码变量,我假设它是由 OAuth2 函数返回的。

我们可以通过简单地获取 URL 并解析代码变量来实现这一点

获取 URL

current_url = driver.current_url;

现在,您可以使用 urlparse 简单地解析 URL。

import urllib.parse as urlparse
from urllib.parse import parse_qs

parsed = urlparse.urlparse(current_url)
OAuth_code = parse_qs(parsed.query)['code']
