我无法通过 google 和 apis 对我的烧瓶应用程序进行身份验证

问题描述

我对编码很陌生，但这几乎没有记录，所以我需要一些帮助。我正在构建一个烧瓶应用程序，但我无法让谷歌身份验证流程正常工作。我使用的是 Pycharm 和 python 3.9 版

我的问题是：我找不到任何解释如何完成身份验证流程的初学者教程。

我不明白如何通过flask与Google Apis交互。（我想使用android-management-api）

我确实明白我需要创建一个服务对象，但只有当我可以验证谷歌流程时才有效，而这就是我现在已经卡住了 5 天的地方。

我已经按照 realpython 和 MattButton 的说明进行了操作。尝试这些说明时，我不断收到错误消息。现在我得到：

Error: While importing 'app',an ImportError was raised:

Traceback (most recent call last):
  File "C:\000 Projects\Applications\PY\flaskProjects\MDM\venv\lib\site-packages\flask\cli.py",line 256,in locate_app
    __import__(module_name)

    from flask_oauth import OAuth

    from urlparse import urljoin
ModuleNotFoundError: No module named 'urlparse'


Process finished with exit code 2

谁能解释一下我做错了什么

我的代码如下：

from flask import Flask,redirect,url_for,session,request,jsonify,render_template
from datetime import datetime

from flask import Flask,session
from flask_oauth import OAuth
import urllib.parse


# You must configure these 3 values from Google Apis console
# https://code.google.com/apis/console
GOOGLE_CLIENT_ID = ''
GOOGLE_CLIENT_SECRET = ''
REDIRECT_URI = '/authorized'  # one of the Redirect URIs from Google Apis console

SECRET_KEY = 'development key'
DEBUG = True

app = Flask(__name__)
app.debug = DEBUG
app.secret_key = SECRET_KEY
oauth = OAuth()

google = oauth.remote_app('google',base_url='https://www.google.com/accounts/',authorize_url='https://accounts.google.com/o/oauth2/auth',request_token_url=None,request_token_params={'scope': 'https://www.googleapis.com/auth/androidmanagement','response_type': 'code'},access_token_url='https://accounts.google.com/o/oauth2/token',access_token_method='POST',access_token_params={'grant_type': 'authorization_code'},consumer_key=GOOGLE_CLIENT_ID,consumer_secret=GOOGLE_CLIENT_SECRET)


@app.route('/')
def index():
    access_token = session.get('access_token')
    if access_token is None:
        return redirect(url_for('login'))

    access_token = access_token[0]

    from urllib.request import Request,urlopen
    from urllib.error import URLError

    headers = {'Authorization': 'OAuth '+access_token}
    req = Request('https://www.googleapis.com/oauth2/v1/userinfo',None,headers)
    try:
        res = urlopen(req)
    except URLError as e:
        if e.code == 401:
            # Unauthorized - bad token
            session.pop('access_token',None)
            return redirect(url_for('login'))
        return res.read()

    return res.read()


@app.route('/login')
def login():
    callback = url_for('authorized',_external=True)
    return google.authorize(callback=callback)


@app.route(REDIRECT_URI)
@google.authorized_handler
def authorized(resp):
    access_token = resp['access_token']
    session['access_token'] = access_token,''
    return redirect(url_for('index'))


@google.tokengetter
def get_access_token():
    return session.get('access_token')


@app.route('/home')
def home():
    return render_template(
        'index.html',title='Home Page',year=datetime.Now().year,)


@app.route('/devices')
def devices():
    return render_template(
        'devices.html',title='Devices',)


@app.route('/policies')
def policies():
    return render_template(
        'policies.html',title='Policies',)


@app.route('/enterprises')
def enterprises():
    return render_template(
        'enterprises.html',title='Enterprises',)


@app.route('/contact')
def contact():
    # """Renders the contact page."""
    return render_template(
        'contact.html',title='Contact',message='ICS-Vertex'
    )


@app.route('/about')
def about():
    return render_template(
        'about.html',title='About',message='Your application description page.'
    )


if __name__ == '__main__':
    app.run()

解决方法

解决了！我发现有两个冲突的库都使用了请求名称

Flask.requests
请求

android-management-api flask google-api google-auth-library python
