微信小程序使用uniapp 开发时，需要获取用户信息用于注册

<button type="default" @click="getinfo">获取用户信息</button>

getinfo() {
                var that = this;
                console.log('获取用户信息')
                wx.getUserProfile({
                    desc: '用于用户登录', // 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: (res) => {
                        console.log(res)
                        that.iv = res.iv
                        that.encryptedData = res.encryptedData
                        that.nickName = res.userInfo.nickName
                        that.sex = res.userInfo.gender
                        that.pic = res.userInfo.avatarUrl
                        uni.login({
                            provider: 'weixin',
                            success: function(loginRes) {
                                that.code = loginRes.code
                                that.wxlogin()
                            }
                        });
                    }
                })
            },
