uniapp微信小程序WebApi_openid、phone接口获取代码详解

1、打开小程序-- > 2、获取openid-->
3、openid 绑user(游客) --->4、获取phone--->
5、openid、phone绑定user(注册)--->6、下次访问 openid直接读取用户

         getOpenid() {
				// #ifdef H5
				this.wxid="o9zUn7SMr5hI47oAGeMqU-pzExxx";
				this.GetToken();//我的后台业务
				// #endif
				
				// #ifdef MP-WEIXIN
				  //获取code
					uni.login({
						provider: 'weixin',
						success: (res) => {
							console.log(res.code) //获取code
							const code = res.code
							//获取成功后
							uni.request({
								url: `https://api.weixin.qq.com/sns/jscode2session?appid=${this.appid}&secret=${this.secret}&js_code=$[code]&grant_type=authorization_code`,
								success: (res) => {
									//获取session_key和openid，此处关联后端进行业务处理
									this.wxid = res.data.openid;
									this.GetToken();//我的后台业务
								},
								fail: (res) => {
									console.log(res.data)
								}
							})
						},
						fail: (res) => {
							console.log(res.data)
						}
					});
				// #endif
			}

        getPhoneNumber(e) {
				//console.log(e);
				if(e.errMsg!="getPhoneNumber:ok")return;
				const mycode=e.code;
				uni.request({
						url: `https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=${this.appid}&secret=${this.secret}`,
						success: (res) => {
							console.log(res.data);
							var accessToken = res.data.access_token;
							uni.request({
								url: "https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=" +
									accessToken,
								method: 'POST',
								data: {
									code:mycode
								},
								success: (res) => {
									console.log("用户手机号获取");
									console.log(res);
								    //写入缓存
									this.user.moblie=res.data.phone_info.purePhoneNumber;
									this.user.name=this.user.name.replace("游客","用户");
									this.$assist.zset('user', this.user);
									this.AddUser();
