通过php文件进行数据中转。经试验有效可行！！！
1、php 部分
1.1、连接数据库
<?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='mysql';//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";}*/?>
1.2、读取php
<?php//header("Content-type: text/html; charset=utf8");include 'connect.php';//调用connect.php文件$something=$_GET['something'];//'小明';//接收小程序传过来的参数'1';//if ($con->connect_error) {die("连接失败：".$con->connect_error);}else {$sql="SELECT * FROM `1students` WHERE `name` = '$something' ";//根据传入的参数查询数据库中的数据$res=$con->query($sql);echo $con->error;print_r($res->fetch_all (MYSQLI_BOTH));if ($res){$data=$res->fetch_all(PDO::FETCH_LAZY);}else{echo '查询出错！';}//fetch_all查询所有行echo json_encode($data);//返回二维数组形式的值供小程序端用}?>
1.3、写入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 {$sql="INSERT INTO `1students`(`name`, `age`, `xb`) VALUES ('$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;}?>
2、微信小程序部分
直接贴代码：
2.1、js部分：
onLoad: function() {var that = this;//读取数据库wx.request({url: 'http://127.0.0.1/get.php',method: 'GET',data: {something: '1'},header: {'content-Type': 'application/json'},success(res) {console.log(res),that.setData({postList: res.data,});}});//写入数据库wx.request({url: 'http://127.0.0.1/post.php',method: 'GET',data: {something1: '小王',something2: '16',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！！！', //这里打印出登录成功icon: 'success',duration: 1000})}}});},
2.2、wxml部分
<text>{{postList}}</text>
2.3、app.json文件中添加
"pages": ["pages/index/index","pages/logs/logs","pages/sql/sql" //对应的位置],
