Question

我不确定调用了什么样的nodejs，所以请原谅我，如果你知道确切的话，请告诉我。

所以提出我的问题，我精通nodejs并在之前的代码中使用异步等待很多。但现在我需要将我的代码迁移到oop编码风格（可能是打字稿样式？）。所以我真的不确定如何使用async await。这是我到现在为止所尝试的：

== server.js

import bookController from './routes/books/bookController';
import bookService from './routes/books/bookService';
import bookQueries from './routes/books/bookQueries';

let bookCtrl = new bookController(bookService, bookQueries);

app.get('/books/allbooks', (request, response) => {
  bookCtrl.getAllBooks(request, response);
});

== bookController.js

export default class bookController extends baseController {
  constructor(bookService, bookQueries){
    super();
    this.bookService = new bookService();
    this.bookQueries = new bookQueries();
  }

  async getAllBooks(request, response){ // Using async here throws error
     var conn = await this.getBookConn();
     var result = await conn.query("select * from books");
     response.status(200).json(result);
  }
}

==基本控制器 **

import mysql from 'promise-mysql';
export default class baseController {
    constructor(){
    }
    getBookConn(){
        let bzConn = mysql.createConnection({
            host: 'abc.com',
            database: 'test',
            user: 'test',
            password: 'test',
            insecureAuth: true
        })
        return bzConn;
    }
}

**
