如何使用 node.js 发送 HTTP/2.0 请求
How to send a HTTP/2.0 request with node.js
如何在 nodejs 中发送 httpVersion 2.0 请求?
几乎所有的请求模块我都试过了,而且都是httpVersion 1.1
自Node.js8.4.0
以来,您可以使用内置的http2 module to implement an http2 server. Or if you want to use http2 with Express, here's a great module on npm: spdy。
下面是来自 express-spdy 的一些代码:
const fs = require('fs');
const path = require('path');
const express = require('express');
const spdy = require('spdy');
const CERTS_ROOT = '../../certs/';
const app = express();
app.use(express.static('static'));
const config = {
cert: fs.readFileSync(path.resolve(CERTS_ROOT, 'server.crt')),
key: fs.readFileSync(path.resolve(CERTS_ROOT, 'server.key')),
};
spdy.createServer(config, app).listen(3000, (err) => {
if (err) {
console.error('An error occured', error);
return;
}
console.log('Server listening on https://localhost:3000.')
});
获取请求:
const http2 = require("http2");
const client = http2.connect("https://www.google.com");
const req = client.request({
":path": "/"
});
let data = "";
req.on("response", (headers, flags) => {
for (const name in headers) {
console.log(`${name}: ${headers[name]}`);
}
});
req.on("data", chunk => {
data += chunk;
});
req.on("end", () => {
console.log(data);
client.close();
});
req.end();
POST 请求
let res = "";
let postbody = JSON.stringify({
key: value
});
let baseurl = 'baseurl'
let path = '/any-path'
const client = http2.connect(baseurl);
const req = client.request({
":method": "POST",
":path": path,
"content-type": "application/json",
"content-length": Buffer.byteLength(postbody),
});
req.on("response", (headers, flags) => {
for (const name in headers) {
console.log(`${name}: ${headers[name]}`);
}
});
req.on("data", chunk => {
res = res + chunk;
});
req.on("end", () => {
client.close();
});
req.end(postbody)
