上代码

后端Python程序

# coding:utf-8

from flask import Flask, request, abort, render_template
import urllib2
import json

app = Flask(__name__)

WECHAT_APPID = "自己的appid"
WECHAT_APPSECRET = "自己的appsecret"

    code = request.args.get("code")

    # 向微信获取access_token
    url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=%s&secret=%s&code=%s&grant_type=authorization_code" \
          % (WECHAT_APPID, WECHAT_APPSECRET, code)
    resp = urllib2.urlopen(url)

    # 微信返回的数据是json格式的
    resp_json_data = resp.read()
    resp_dict_data = json.loads(resp_json_data)

    # 提取access_token
    access_token = resp_dict_data.get("access_token")

if __name__ == '__main__':
    app.run(port=8000, debug=True)

前端index.html文件代码


<html>
<head>
    <meta charset="utf-8">
    <title>{{user["nickname"]}}的个人主页title>

<body>
    <img alt="头像" src="{{user['headimgurl']}}" width="60">
