【课程章节更新】微信小程序 getUserProfile 新接口使用
起因
大家都知道我有个 Python Flask构建微信小程序订餐系统 课程。这个课程主要是讲解 小程序在线商城的。最近微信小程序更新了获取用户信息的接口:getUserInfo 换成了getUserProfile
实践过程
小程序修改
pages/index/index.wxml 修改如下
<button class="confirm-btn" bindtap="getUserProfile" wx:if="{{regFlag==false}}">授权登录</button>
pages/index/index.js 修改如下
在login方法之后新增加如下方法,为新加的按钮添加触发事件 getUserProfile: function (e) { var that = this; wx.getUserProfile({ desc: '用于完善会员资料', // 声明获取用户个人信息后的用途,后续会展示在弹窗中,请谨慎填写 success: function (res) { var data = res.userInfo; data['openid'] = that.data.openid; wx.request({ url: app.buildUrl('/member/login'), header: app.getRequestHeader(), method: 'POST', data: data, success: function (res) { if (res.data.code != 200) { app.alert({'content': res.data.msg}); return; } app.setCache("token", res.data.data.token); that.goToIndex(); } }); } }) }
后端代码修改
在controllerr/api/Member.py 文件修改
将 最开头的两个方法换成这样就ok了,可以全部替换 @route_api.route("/member/login",methods = [ "GET","POST" ]) def login(): resp = { 'code':200 ,'msg':'操作成功~','data':{} } req = request.values openid = req['openid'] if 'openid' in req else '' #换了新的接口,那就更简单了 #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) # openid = MemberService.getWeChatOpenId( code ) if openid is None or len(openid) < 1: resp['code'] = -1 resp['msg'] = "调用微信出错" return jsonify(resp) nickname = req['nickName'] if 'nickName' in req else '' sex = req['gender'] if 'gender' in req else 0 avatar = req['avatarUrl'] if 'avatarUrl' in req else '' ''' 判断是否已经测试过,注册了直接返回一些信息 ''' bind_info = OauthMemberBind.query.filter_by( openid = openid,type = 1 ).first() if not bind_info: model_member = Member() model_member.nickname = nickname model_member.sex = sex model_member.avatar = avatar model_member.salt = MemberService.geneSalt() model_member.updated_time = model_member.created_time = getCurrentDate() db.session.add(model_member) db.session.commit() model_bind = OauthMemberBind() model_bind.member_id = model_member.id model_bind.type = 1 model_bind.openid = openid model_bind.extra = '' model_bind.updated_time = model_bind.created_time = getCurrentDate() db.session.add(model_bind) db.session.commit() bind_info = model_bind member_info = Member.query.filter_by(id = bind_info.member_id).first() token = "%s#%s" % (MemberService.geneAuthCode(member_info), member_info.id) resp['data'] = {'token': token} return jsonify( resp ) @route_api.route("/member/check-reg",methods = [ "GET","POST" ]) def checkReg(): 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) openid = MemberService.getWeChatOpenId(code) if openid is None: resp['code'] = -1 resp['msg'] = "调用微信出错" resp['data'] = openid return jsonify(resp) bind_info = OauthMemberBind.query.filter_by(openid=openid, type=1).first() if not bind_info: resp['code'] = -1 resp['msg'] = "未绑定" resp['data'] = openid return jsonify(resp) member_info = Member.query.filter_by( id = bind_info.member_id).first() if not member_info: resp['code'] = -1 resp['msg'] = "未查询到绑定信息" resp['data'] = openid return jsonify(resp) token = "%s#%s"%( MemberService.geneAuthCode( member_info ),member_info.id ) resp['data'] = { 'token':token } return jsonify(resp)
原理讲解
原来的方式
先通过checkLogin方法中的wx.login 获取code,后台通过code获取openid 判断是否已经注册过会员了
如果有 就直接登录成功
如果没有就显示 授权登录的按钮
这时候会获取到基本信息(注意这个时候的基本信息昵称都是微信用户了)和 wx.login 的 code,然后在传递到后台的登录接口。后台是通过code 获取openid的。
现在的方式
先通过checkLogin方法中的wx.login 获取code,后台通过code获取openid 判断是否已经注册过会员了
如果有 就直接登录成功
如果没有就显示 授权登录的按钮,同时后台会把openid 返回来给js存储起来
这个时候的按钮和以前是有一定的区别了,可以获取用户的基本信息 和 openid ,然后在传递到后台的登录接口
