Python：如何使用 Bottle 从本地主机获取某个 url？

问题描述

我正在尝试为 Spotify 执行授权代码流程，我使用 Bottle 打开本地主机，然后转到授权页面，之后我被定向到 URL 中带有 access_token 的页面。我如何使用 Bottle（或任何其他库）来获取该 url（它是在起始 localhost 页面之后的第 3 个页面加载以及授予 Spotify 作为用户页面的权限）。

我尝试使用 Selenium，但是当它自动让浏览器打开 localhost 页面时，它不会加载，我什至没有看到 Bottle 正在监听端口。

在运行打开 selenium 的函数之前，我什至尝试使用睡眠，但没有成功

我的代码如下：

from urllib.parse import urlencode
from spotipy import oauth2
from bottle import route,run,request
from selenium import webdriver
import time
import urllib


client_id = ''
client_secret = ''
port_number = 8080
redirect_uri = 'http://localhost:8080/callback'
scope = 'user-read-recently-played'
method = 'GET'

# getting the token following the Authorization code flow - the user will grant permission for the app to use their data.


def get_lookup_url():
    auth_url = 'https://accounts.spotify.com/authorize'
    auth_data = {
        'client_id': f'{client_id}','response_type': 'code','redirect_uri': f'{redirect_uri}','scope': f'{scope}'
    }

    encoded_auth_data = urlencode(auth_data)

    lookup_url = f'{auth_url}?{encoded_auth_data}'
    # r = requests.get(lookup_url)
    return lookup_url
    # print(lookup_url)
    # print(r.status_code)
    # print(r.text)


# helper function to get the access toekn from the url
def get_access_token_from_url():
    driver = webdriver.Chrome('/Users/****/****/chromedriver')
    driver.get(redirect_uri)
    driver.implicitly_wait(10) # seconds - enough time for me to login to spotify and click the agree button
    # urllib.request.urlopen(redirect_uri)
    access_token_split = ''
    current_url = ''
    # current_url = driver.current_url
    print(current_url) # TODO remove this line later
    if 'access_token' in current_url:
        split = current_url.split('#')
        print(split[1]) # getting what's after the '#'
        split_again = split[1].split('&')
        print(split_again) # TODO remove this line later
        for i in split_again:
            if 'access_token' in i:
                access_token_split = i.split('=')
                print(access_token_split) # TODO remove this line later
        return access_token_split[1]


# login button goes to the lookup url
@route('/callback')
def html_login_button():
    auth_url = get_lookup_url() # assigning the function to a variable
    htmlLoginButton = "<a id='login' href='" + auth_url + "'>Login to Spotify</a>"
    return htmlLoginButton

# time.sleep(10)
# looking for the access_token in the url
get_access_token_from_url()

run(host='',port=port_number,debug=True) # opens at http://localhost:8080/callback```
