使用chai-http响应解析承诺

Question

我是NodeJs的新手，正在尝试运行测试。我正在尝试从get调用返回http响应，以便可以对其运行断言。SendGetResponse()返回promise，sendResponse等待这个promise的实现。但我得到(node:2152) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'then‘of undefined，sendResponse不等待。

任何帮助都将不胜感激！

async sendResponse(){
  this.setUpRequest();
  if (this.verb == 'get'){
    var Promise1 = await this.sendGetRequest();
    console.log("Going to resolve promise");
    console.log(Promise1);
  }
  console.log('Leaving Sendresponse');
  return this.ResponseMessage;
}

sendGetRequest() {
  console.log("In SendGetRequest()");

  const SendRequest = this.GetRequest(this.path,this.headers);
  SendRequest.then(function(res,err){       
    return new Promise(function(resolve, reject){
      if (err == null){
        console.log("Resolving promise");
        resolve(res.text);
      }
      else{
        console.log("Rejecting promise");
        reject(err);
      }
    }).catch(error => { 
      console.log('Exception caught', err.message);
    });
  });
}

GetRequest(path,headers){ 
  console.log("In GetRequest()");
  return chai.request(baseurl).get(path).set(headers);
}

查看chai Requests documentation，如果要设置任何HTTP属性，如标题或表单数据，看起来需要调用.send()。尝试对GetRequest()进行以下更改

function GetRequest(path, headers) {
  return chai.request(baseUrl)
    .get(path)
    .set(headers)
    .send();
}
