第一步：開(kāi)放平臺(tái)上添加 獲取會(huì)員手機(jī)號(hào)的功能包（需要主賬號(hào)簽約，子賬號(hào)不可見(jiàn)）

https://open.alipay.com/operation/mini/ops/mini-summary

第二步：添加主動(dòng)觸發(fā)按鈕

getPhoneNumber：授權(quán)成功后的回調(diào)

onAuthError：拒絕授權(quán)后的回調(diào)

<button open-type="getAuthorize"> my.getPhoneNumber({
        success: (res) => {
          let encryptedData = JSON.parse(res.response).response;
          //userObject.phoneInfo = res.response;
          console.log(res.response);
          //手機(jī)號(hào)解密請(qǐng)求
          phoneAuth(res.response);
        },
        fail: (res) => {
          console.log(res);
        }
      });
function phoneAuth(e){
//后臺(tái)請(qǐng)求操作 主要是發(fā)送加密數(shù)據(jù)
}

第四步：后臺(tái)解析（低版本SDK：https://download.csdn.net/download/qq_36894527/12875709）
