短信验证码发送不了

const Core = require('@alicloud/pop-core');

      var client = new Core({
        accessKeyId: 'xxxxxxxx',
        accessKeySecret: 'xxxxxxxx',
        endpoint: 'https://dysmsapi.aliyuncs.com',
        apiVersion: '2017-05-25'
      });

      correctCode = this.randomCode();
      var params = {
        "RegionId": "cn-hangzhou",
        "PhoneNumbers": this.phone,
        "SignName": "xxxxxxxx",
        "TemplateCode": "xxxxxxxx",
        "TemplateParam": `{\"code\":\"${correctCode}\"}`
      };

      var requestOption = {
        method: 'POST'
      };

      client.request('SendSms', params, requestOption).then((result) => {
        console.log(JSON.stringify(result));
        if(window.android){
          window.android.log(JSON.stringify(result))
        }
      }, (ex) => {
        console.log(ex);
      })

代码就是自动生成的，xxxx参数都填上了对应的，但是浏览器运行的时候，报这些错误，以前没用过vue写，不知道该怎么办。有人能帮下忙吗，谢谢！
