微信小程序通过getPhoneNumber后台PHP解密获取用户手机号码

之前做的版本用户这块是以获取用户openid为凭证，最近改版重新整理了一下，新增注册登录以手机号码为主，

两种（正常注册手机号码-密码+一键获取当前用户手机号码）

getPhoneNumber这个组件要通过button来实现。将button中的open-type=“getPhoneNumber”,并且绑定bindgetphonenumber事件获取回调。

在使用这个组件之前必须先调用 login 接口

然后传递code，iv，encryptedData参数到后台，后台解密

示例

 

 

<button open-type="getPhoneNumber" bindgetphonenumber="getPhoneNumber"
 hover-class="none">一键自动注册</button>

　　

  getPhoneNumber: function (e) {
      console.log(e.detail.errMsg)
      if (e.detail.errMsg == \'getPhoneNumber:fail user deny\') {
        wx.showModal({
          title: \'提示\',
          showCancel: false,
          content: \'未授权\',
          success: function (res) { }
        })
      } else {
        wx.login({
          success: function (res) {
            var code = res.code;
            if (res.code) {
              //发起网络请求  
              console.log(res.code)
            } else {
              console.log(\'获取用户登录态失败！\' + res.errMsg)
            }
            wx.showModal({
              title: \'提示\',
              showCancel: false,
              content: \'同意授权\',
              success: function (res) {
                var that = this;
                console.log(123)
                wx.request({

                  data: {
                    code: code,
                    iv: e.detail.iv,
                    encryptedData: e.detail.encryptedData

                    if(res.data.code == "200"){
                      console.log(res.data.data)

                        content: \'一键绑定失败，请重新尝试\',
                        success: function (res) {
                          if (res.confirm) {
