通过code获取openid

https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/login/auth.code2Session.html

https://api.weixin.qq.com/sns/jscode2session?appid=APPID&secret=SECRET&js_code=JSCODE&grant_type=authorization_code

appid可以登录微信后台获取。

base_setting.py 定義配置：

MINA_APP = {
    'appid' : 'wxaaaf50c8265cf721',
    'appkey' : '3671f6b2eaf7946e7bb2eac521be403'
}

python安裝扩展发送请求

pip install requests

member.py发送请求

import requests
@route_api.route("/member/login", methods = ["GET","POST"])
def login():
    resp = {'code':200, 'msg':'操作成功', 'data':{}}
    req = request.values

    code = req['code'] if 'code' in req else ''

    if not code or len(code)<1:
        resp['code'] = -1
        resp['msg'] = '需要code'

        return jsonify(resp)

    url = "https://api.weixin.qq.com/sns/jscode2session?appid={0}&secret={1}&js_code={2}&grant_type=authorization_code"\
        .format(app.config['MINA_APP']['appid'], app.config['MINA_APP']['appkey'], code)

    r = requests.get(url)
    res = r.text
    app.logger.info(res)

    return jsonify(resp)

启动小程序 并且启动服务

成功返回session_key和openid

我们只需要openid

将字符串转换为json数据

@route_api.route("/member/login", methods = ["GET","POST"])
def login():
    resp = {'code':200, 'msg':'操作成功', 'data':{}}
    req = request.values

    code = req['code'] if 'code' in req else ''

    if not code or len(code)<1:
        resp['code'] = -1
        resp['msg'] = '需要code'

        return jsonify(resp)

    url = "https://api.weixin.qq.com/sns/jscode2session?appid={0}&secret={1}&js_code={2}&grant_type=authorization_code"\
        .format(app.config['MINA_APP']['appid'], app.config['MINA_APP']['appkey'], code)

    r = requests.get(url)
    res = json.loads(r.text)
    openid = res['openid']

    return jsonify(resp)

创建member表和绑定表

show databases;
use food_db

CREATE TABLE `member` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `nickname` varchar(100) NOT NULL DEFAULT '' COMMENT '会员名',
  `mobile` varchar(11) NOT NULL DEFAULT '' COMMENT '会员手机号码',
  `sex` tinyint(1) NOT NULL DEFAULT '0' COMMENT '性别 1：男 2：女',
  `avatar` varchar(200) NOT NULL DEFAULT '' COMMENT '会员头像',
  `salt` varchar(32) NOT NULL DEFAULT '' COMMENT '随机salt',
  `reg_ip` varchar(100) NOT NULL DEFAULT '' COMMENT '注册ip',
  `status` tinyint(1) NOT NULL DEFAULT '1' COMMENT '状态 1：有效 0：无效',
  `updated_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '最后一次更新时间',
  `created_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '插入时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='会员表';

CREATE TABLE `oauth_member_bind` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `member_id` int(11) NOT NULL DEFAULT '0' COMMENT '会员id',
  `client_type` varchar(20) NOT NULL DEFAULT '' COMMENT '客户端来源类型。qq,weibo,weixin',
  `type` tinyint(3) NOT NULL DEFAULT '0' COMMENT '类型 type 1:wechat ',
  `openid` varchar(80) NOT NULL DEFAULT '' COMMENT '第三方id',
  `unionid` varchar(100) NOT NULL DEFAULT '',
  `extra` text NOT NULL COMMENT '额外字段',
  `updated_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '最后更新时间',
  `created_time` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP COMMENT '插入时间',
  PRIMARY KEY (`id`),
  KEY `idx_type_openid` (`type`,`openid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='第三方登录绑定关系';

创建数据库orm

創建文件夾

flask-sqlacodegen "mysql://root:123456@127.0.0.1/food_db" --tables member --outfile "order/common/models/member/Member.py" --flask
flask-sqlacodegen "mysql://root:123456@127.0.0.1/food_db" --tables oauth_member_bind --outfile "order/common/models/member/OauthMemberBind.py" --flask

创建好文件后，统一替换db变量：
