    })
  },

    })
  },
  getSmsCaptcha(e) {
    var that = this;
    var mobile = that.data.mobile;
    if(mobile == ''){
      my.showToast({
        type: 'none',
        content: '请输入手机号码',
        duration: 3000,
      });
      return ;
    }
    
    that.countdown.start();
    zhenzisms.client.init('https://sms_developer.zhenzikj.com', '你的榛子云appID', '你的榛子云appSecret');
    zhenzisms.client.sendCode(function (res) {
      my.showToast({
        type: 'none',
        content: res.data.data,
        duration: 2000
      })
    }, mobile, '验证码为:{code}', '', 60 * 5, 4);

    //获得余额
    // zhenzisms.client.balance(function(res){
    //   console.info(res);
    //   console.info('余额: '+res.data.data)
    // });

    //获得短信详情
    // zhenzisms.client.findSmsByMessageId(function(res){
    //   console.info(res);
    //   console.info('详情: '+res.data.data)
    // }, 'aaaabbbbba');

  },
  //保存
  save(e) {
    console.info('手机号: ' + this.data.mobile);
    console.info('验证码: ' + this.data.code);

     //检验验证码
    var result = zhenzisms.client.validateCode(this.data.mobile, this.data.code);
    if (result == 'ok'){
      console.info('验证正确');
    } else if (result == 'empty'){
      console.info('验证错误, 未生成验证码!');
    } else if (result == 'number_error') {
      console.info('验证错误，手机号不一致!');
    } else if (result == 'code_error') {
      console.info('验证错误，验证码不一致!');
    } else if (result == 'code_expired') {
      console.info('验证错误，验证码已过期!');
    }
  }

});

引入一个自己写的countdown.js 倒计时的插件。
