可以多次激发“data”事件:https://nodejs.org/api/http.html#http_class_http_clientrequest
您必须监听“End”事件，并将“Data”事件中的所有块连接在一起，以获得全身响应。
const express = require('express');
const app = express();
const https = require('https');
const url = "https://api.thevirustracker.com/free-api?countryTimeline=US";
app.get("/", (req, res) => {
res.send("Server is Running")
https.get(url, (response) => {
const chunks = [];
response.on("data", (data) => {
chunks.push(data);
})
response.on("end", () => {
let size = chunks.reduce((prev, cur) => {
return prev + cur.length;
}, 0);
let data = Buffer.concat(chunks, size).toString();
console.log(JSON.parse(data))
});
})
})
app.listen(3000, () => console.log("Server is Running 0n 5000"));
