微信登陆

功能

  • 支持snsapi_base, 以snsapi_base为scope发起的网页授权，是用来获取进入页面的用户的openid的，并且是静默授权并自动跳转到回调页的。用户感知的就是直接进入了回调页（往往是业务页面）
  • 支持snsapi_userinfo, 以snsapi_userinfo为scope发起的网页授权，是用来获取用户的基本信息的。但这种授权需要用户手动同意，并且由于用户同意过，所以无须关注，就可在授权后获取该用户的基本信息。

文档

微信详细文档请点击

初始化

from wechat import WechatAuth
# from wechat.auth import WechatAuth

auth = WechatAuth('app_id', 'app_key')

引导用户跳转到授权页面

url = auth.authorize("http://code.show/login/wechat/callback", "snsapi_base")

通过code换取网页授权access_token

data = auth.access_token(code)
print data.access_token
print data.refresh_token
print data.openid

小程序通过js_code换取session跟openid

data = auth.jscode2session(code)

拉取用户信息

如果是snsapi_userinfo则需要

auth.user_info(data.access_token)

刷新token

auth.refresh_token(data.refresh_token)

用法

# -*- coding: utf-8 -*-


from datetime import datetime, timedelta
from flask import Flask, redirect, request, url_for
from wechat.auth import WechatAuth


app = Flask(__name__)

app_id = ''
app_secret = ''
auth = WechatAuth(app_id, app_secret)


@app.route("/login")
def login():
    openid = request.cookies.get("openid")
    next = request.args.get("next") or request.referrer or "/",
    if openid:
        return redirect(next)

    callback = url_for("authorized", next=next, _external=True)
    url = auth.authorize(callback, "snsapi_base")
    return redirect(url)


@app.route("/authorized")
def authorized():
    code = request.args.get("code")
    if not code:
        return "ERR_INVALID_CODE", 400
    next = request.args.get("next", "/")
    data = auth.access_token(code)
    openid = data.openid
    resp = redirect(next)
    expires = datetime.now() + timedelta(days=1)
    resp.set_cookie("openid", openid, expires=expires)
    return resp
