如何僅使用 async/await 語法重寫 axios promise 模塊？

Question

如何僅使用 async/await 語法重寫 Axios promise 模塊？ 請我是 Axios 和 promise 的新手，異步語法 => 我應該在.push() 中放什么？

const axios = require("axios");
const _ = require("lodash");
const queue = require("queue");

// To control the request rate
const GetDataQueue_B = queue({ autostart: true, concur: 1 });
// someone's codes
const getDATA = () => {
    return new Promise((resolve, reject) => {
      // To make sure only one request call
      GetDataQueue_B.push(
        async () => {
            try{
            const res = await axios.get(`${whichAPI}/api`);
            resolve(
                _.map(
                _.get(res, "data.infor"), 
                    obj => ({
                        quotes:obj.quotes,
                        author:boj.author,
                    })
                )
            );
            }catch(e) {reject(e);console.log(e);}
        }
      );
    }); 

下面是我的嘗試： => 我應該在.push() 中放什么？

const getDATA_1 = async () => {
    try{
    const res = await axios.get(`${whichAPI}/api`);
    const data =  _.map(
                    _.get(res, "data.infor"), 
                        obj => ({
                            quotes:obj.quotes,
                            author:boj.author,
                        })
                    )                 
    GetDataQueue_B.push(); // => what should i put inside the .push() method?
    return data;
    }catch(e){console.log(e);}
  };

Answer 1

queue在這里不是干凈代碼的最佳選擇，因為雖然它允許推送返回 promise 的函數，但它本身不會返回 promise。

我建議改用p-limit 。 它是這樣工作的：

const pLimit = require("p-limit");

const myQueue = pLimit(5); // Allow only 5 things running in parallel

const promise = myQueue(async () => { /* stuff */ });
// promise will resolve once the passed function ran, and will return its
// result.

因此，代碼如下所示：

const axios = require("axios");
const _ = require("lodash");
const pLimit = require("p-limit");

// To control the request rate
const GetDataQueue_B = pLimit(1);
// someone's codes
const getDATA = () => GetDataQueue_B(async () => {
  const res = await axios.get(`${whichAPI}/api`);
  return _.map(
    _.get(res, "data.infor"), 
      obj => ({
        quotes: obj.quotes,
        author: boj.author,
      })
    )
  );
}); 

我刪除了try / catch ，因為它並沒有真正做任何事情——這里的錯誤無論如何都會拒絕生成的 promise。
