python实现微信公众平台网页授权登录获取用户基本信息

from urllib import parse
import requests

获取access_token

appid = "wxa77a00333cd8d99a"
secret = "6f61xxxxxxxxxx"
get_access_token_url = f"https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={appid}&secret={secret}"

access_token = requests.get(get_access_token_url).json().get("access_token")

获取微信服务器ip列表

get_server_ip_list_url = f"https://api.weixin.qq.com/cgi-bin/get_api_domain_ip?access_token={access_token}"
server_ip_list = requests.get(get_server_ip_list_url).json()
print("server_ip_list:", server_ip_list["ip_list"])

获取微信callback IP地址

callback_url = f"https://api.weixin.qq.com/cgi-bin/getcallbackip?access_token={access_token}"
callback_ip = requests.get(callback_url).json()
print("callback_ip_list:", callback_ip["ip_list"])

查询rid信息

rid_url = f"https://api.weixin.qq.com/cgi-bin/openapi/rid/get?access_token={access_token}"
rid_ret = requests.post(rid_url, data={"rid": "6260f2e7-2caa4faa-752c531"})
print(rid_ret.text)

scope = "snsapi_userinfo"
scope = "snsapi_base"
redirect_uri = parse.quote("http://192.168.110.10:8000")
url = f"https://open.weixin.qq.com/connect/oauth2/authorize?appid={appid}&redirect_uri={redirect_uri}&response_type=code&scope={scope}&state=STATE#wechat_redirect"
print(url)

import json
from flask import Flask, request

app = Flask(__name__)


@app.route(rule="/")
def index():
    ### 1. 获取code
    code = request.args.get("code")
    state = request.args.get("state")
    print(code, state)

    ### 2. 通过code换取网页授权access_token和用户openid
    """
    获取code后，请求以下链接获取access_token： https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code
    """
    url = f"https://api.weixin.qq.com/sns/oauth2/access_token?appid={appid}&secret={secret}&code={code}&grant_type=authorization_code"
    access_token_openid_dict = requests.get(url).json()
    print(access_token_openid_dict)
    access_token = access_token_openid_dict["access_token"]
    refresh_token = access_token_openid_dict["refresh_token"]
    openid = access_token_openid_dict["openid"]

    ### 3. 刷新access_token（如果需要）
    """
    获取第二步的refresh_token后，请求以下链接获取access_token： https://api.weixin.qq.com/sns/oauth2/refresh_token?appid=APPID&grant_type=refresh_token&refresh_token=REFRESH_TOKEN
    """
    url = f"https://api.weixin.qq.com/sns/oauth2/refresh_token?appid={appid}&grant_type=refresh_token&refresh_token={refresh_token}"
    ret = requests.get(url).json()
    print(ret)

    ##3 4. 拉取用户信息(需scope为 snsapi_userinfo)
    """
    http：GET（请使用https协议） https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN
    """
    url = f"https://api.weixin.qq.com/sns/userinfo?access_token={access_token}&openid={openid}&lang=zh_CN"
    ret = requests.get(url).text
    import json
    ret = json.loads(ret)
    print(ret)
    data = json.loads(ret.text.encode("ISO-8859-1").decode("utf-8"))  # 解决微信编码不一致问题
    print(data)

    ### 附：检验授权凭证（access_token）是否有效
    """
    http：GET（请使用https协议） https://api.weixin.qq.com/sns/auth?access_token=ACCESS_TOKEN&openid=OPENID
    """
    url = f"https://api.weixin.qq.com/sns/auth?access_token={access_token}&openid={openid}"
    ret2 = requests.get(url).json()
    print(ret2)

    return ret
