微信小程序获取手机号 前台+php后台

两个部分三个位置，前台加后台，前台分为js+wxml

前端

wxml

<button class='bottom' open-type="getPhoneNumber"  bindgetphonenumber="getphonenumber"   >
    授权登录
</button>

js：需要修改两个请求连接

// pages/demo/demo.js
Page({
  getphonenumber: function (e) {
    if (e.detail.errMsg == 'getPhoneNumber:fail user deny') {
      wx.showModal({
        title: '提示',
        showCancel: false,
        content: '未授权',
        success: function (res) {}
      })
    } else {
      //调用接口获取登录凭证
      wx.login({
        success: function (res) {
          //获取到的code
          var code = res.code;
          if (!code) {
            console.log('获取用户登录态失败！' + res.errMsg)
          }
          //获取opendi、session_key
          wx.request({
            url: 'htt son/wei/v1/getopenid',
            method: 'POST',
            data: {
              code: code,
            },
            header: {
              'content-type': 'application/json'
            },
            success: function (res) {
              wx.setStorageSync('openid', res.data.openid);

              var encryptedData = e.detail.encryptedData
              var iv = e.detail.iv
              var se_key = res.data.session_key
              console.log(res);
              //换取手机号
              wx.request({
                url: 'https    wp-json/wei/v1/getphone',
                method: 'POST',
                data: {
                  // 必须，获取手机号
                  encryptedData: encryptedData,
                  iv: iv,
                  session_key: se_key,
                  // 修改数据库所需
                  uid:3
                },
                header: {
                  'Content-Type': 'application/x-www-form-urlencoded'
                },
                method: 'POST',
                success: function (res) {
                  console.log(res);
                  /* 
                 每个人都不同
				countryCode: "86"  
				phoneNumber: "123"
				purePhoneNumber: "7823"
				watermark: {timestamp: 16175702, appid: "wxa0fe31"}
                 
                 */
                }
              })
            },
          });
        }
      });
    }
  },

})

后台

封装了三个功能：

  1. 获取openid+session_key
  2. 获取用户手机号
  3. 支付

需要修改 __construct里的内容，支付需要所有信息获取完全
