问题已解决，是用户名获取不到 ------------------------------------------------------------------------------------------------- 为什么头像拒绝读取的用户，依然可以跳转到下一页log呢？

openId，不让获取头像时，返回值 是null?，应该不是，以null写的判断不起效

1、ewm云函数 const cloud = require('wx-server-sdk')  cloud.init({       env: 'xxxxxxxx'         }) exports.main = async (event, context) => {   try {     const result = await cloud.openapi.wxacode.createQRCode({         path:event.urlname,  //未验证         width: 410       })     const file = await cloud.uploadFile({     cloudPath: 'img.jpg',     fileContent: result.buffer,   })     return file    } catch (err) {     return err   } } 2、index.js 调用代码 console.log('测试',dname) wx.cloud.callFunction({      //扫码传递参数pdname2(编号)     name: "ewm",     data: {       urlname: '../tt index/index?dname=' + dname     },     success: res =>{       console.log('test1',res.result)       this.setData({         ima:res.result.fileID       })     },     fail: err =>{       console.log()     }   }) 3、index.wmsl <view class="wm1"> <image style="width: 200px; height: 200px; background-color: #eeeeee;"  src="{{ima}}"></image> </view> ------------------------------------------------------------------------------------------------- 另，有pages/tt index/index能访问。 扫码后，提示：页面不存在

1.新建template文件夹用于保存tabBar模板，template/template.wxml<template name="tabBar"> <view class="tabBar"> <block wx:for="{{tabBar}}" wx:for-item="item" wx:key="tabBar"> <view class="tabBar-item"> <navigator open-type="reLaunch" url="{{item.pagePath}}"> <view><image class="icon" src='{{item.iconPath}}'></image></view> <view class="{{item.current== 1 ? 'tabBartext' :''}}">{{item.text}}</view> </navigator> </view> </block> </view> </template> 2.创建template.wxss.icon{ width:54rpx; height: 54rpx; } .tabBar{ width:100%; position: fixed; bottom:0; padding:10rpx; margin-left:-4rpx; background:#F7F7FA; font-size:24rpx; color:#8A8A8A; box-shadow: 3rpx 3rpx 3rpx 3rpx #aaa; z-index: 9999; } .tabBar-item{ float:left; width:20%; text-align: center; overflow: hidden; } /*当前字体颜色*/ .tabBartext{ color:red; } .navigator-hover{ background-color: rgba(0, 0, 0, 0); } 3.创建template.js,初始化数据//初始化数据 function tabbarinit() { return [ { "current": 0, "pagePath": "/pages/dashboard/index", "iconPath": "/images/goback.png", "text": "返回商城" }, { "current": 0, "pagePath": "/pages/collage/index", "iconPath": "/images/collage1.png", "selectedIconPath": "/images/collage.png", "text": "拼团首页" }, { "current": 0, "selectedIconPath": "/images/list.png", "iconPath": "/images/list1.png", "pagePath": "/pages/collage-list/index", "text": "活动列表" }, { "current": 0, "selectedIconPath": "/images/collage-order.png", "iconPath": "/images/collage-order1.png", "pagePath": "/pages/collage-order/index", "text": "我的订单" }, { "current": 0, "selectedIconPath": "/images/group.png", "iconPath": "/images/group1.png", "pagePath": "/pages/group/index", "text": "我的团" } ] } //tabbar 主入口 function tabbarmain(bindName = "tabdata", id, target) { var that = target; var bindData = {}; var otabbar = tabbarinit(); otabbar[id]['iconPath'] = otabbar[id]['selectedIconPath']//换当前的icon otabbar[id]['current'] = 1; bindData[bindName] = otabbar that.setData({ bindData }); } module.exports = { tabbar: tabbarmain } 4.使用方法先把样式文件载入app.wxss@import "/template/template.wxss"; 新建一个页面，比如index.wxml,引入模板<import src="../../template/template.wxml"/> <template is="tabBar" data="{{tabBar:bindData.tabBar}}"/> index.js 初始化数据var template = require('../../template/template.js'); Page({ onLoad: function () { template.tabbar("tabBar", 0, this)//0表示第一个tabbar }, }) 其它新建页面也跟index.wxml一样，初始化数据。-------------------------------------------------------------------------------------------------------------------------------------------- 在电脑上运行正常，但真机调试时，出现错误： Error: module "template/template.js" is not defined

一、微信小程序 1、index.js const app = getApp() Page({ fortn: function () { //写入数据库 wx.request({ url: 'http://xxxxxxxxx/post.php', method: 'GET', data: { something1: '李四', something2: '25', something3: '0' }, header: { 'content-Type': 'application/x-www-form-urlencoded' }, success(res) { console.log(res.data); if (res.data.status == 0) { wx.showToast({ title: '提交失败！！！', icon: 'loading', duration: 1500 }) } else { wx.showToast({ title: '提交成功！！！', icon: 'success', duration: 1000 }) } } }); }, }) 2、index.wxml <button class="ff" bindtap='fortn' >增加</button> -------------------------------------------------------------- 二、服务器端 1、connect.php <?php //header("Content-type: text/html; charset=utf8"); //1. 声明字符编码  $host='127.0.0.1';//数据库ip  $user='root';//用户名 $password='123456';//密码  $dbName='mymy';//要连接的数据库名  $con =new mysqli($host,$user,$password,$dbName,3308);//数据库连接  /*if ($con->connect_error) {   echo "系统异常，连接数据库失败"; } else { echo "连接成功"; }*/ ?> 2、post.php <?php //header("Content-type: text/html; charset=utf8"); include 'connect.php';//调用connect.php文件 $something1=$_GET['something1'];//'小明';// $something2=$_GET['something2'];//'16';// $something3=$_GET['something3'];//'0';// if ($con->connect_error) { die("连接失败：".$con->connect_error); } else  {   $sql="INSERT INTO `doctor`(`name`, `age`, `xb`) VALUES ('$something1','$something2','$something3');";   $res=$con->query($sql);   if($res){     $arr['status'] = 1;     $arr['info'] = 'success'; }else{     $arr['status'] = 0;     $arr['info'] = 'error'; } echo json_encode($arr); die; }  ?> --------------------------------------------------- 三、mysql数据库名称为：mymy,表单是doctor，字段名称为`name`, `age`, `xb` ----------------------------------------------------------------------------- 增加数据不成功，不知为什么？(服务器http服务能访问到)
