Requests-OAuthlib：面向人类的 OAuth
Requests-OAuthlib 使用 Python Requests 和 OAuthlib 库，为构建 OAuth1 和 OAuth2 客户端提供一个易于使用的 Python 界面。
概述
一个连接到 Github OAuth2 API 的简单 Flask 应用程序看起来大约像这样
from requests_oauthlib import OAuth2Session
from flask import Flask, request, redirect, session
from flask.json import jsonify
# This information is obtained upon registration of a new GitHub
client_id = "<your client key>"
client_secret = "<your client secret>"
authorization_base_url = 'https://github.com/login/oauth/authorize'
token_url = 'https://github.com/login/oauth/access_token'
secret_key = "<secret_key for use flask session>"
app = Flask(__name__)
app.config['SECRET_KEY'] = secret_key
@app.route("/login")
def login():
github = OAuth2Session(client_id)
authorization_url, state = github.authorization_url(authorization_base_url)
# State is used to prevent CSRF, keep this for later.
session['oauth_state'] = state
return redirect(authorization_url)
@app.route("/callback")
def callback():
github = OAuth2Session(client_id, state=session['oauth_state'])
token = github.fetch_token(token_url, client_secret=client_secret,
authorization_response=request.url)
return jsonify(github.get('https://api.github.com/user').json())
