以下代码显示了如何从HTML表单读取值。正如@pimvdb所说，您需要使用request.on（’data’…）来捕获正文的内容。
const http = require('http')const server = http.createServer(function(request, response) { console.dir(request.param) if (request.method == 'POST') { console.log('POST') var body = '' request.on('data', function(data) { body += data console.log('Partial body: ' + body) }) request.on('end', function() { console.log('Body: ' + body) response.writeHead(200, {'Content-Type': 'text/html'}) response.end('post received') }) } else { console.log('GET') var html = ` <html> <body> <form method="post" action="http://localhost:3000">Name: <input type="text" name="name" /> <input type="submit" value="Submit" /> </form> </body> </html>` response.writeHead(200, {'Content-Type': 'text/html'}) response.end(html) }})const port = 3000const host = '127.0.0.1'server.listen(port, host)console.log(`Listening at http://${host}:${port}`)如果您使用Express.js和Bodyparser之类的东西，那么它将看起来像这样，因为Express会处理request.body串联
var express = require('express')var fs = require('fs')var app = express()app.use(express.bodyParser())app.get('/', function(request, response) { console.log('GET /') var html = ` <html> <body> <form method="post" action="http://localhost:3000">Name: <input type="text" name="name" /> <input type="submit" value="Submit" /> </form> </body> </html>` response.writeHead(200, {'Content-Type': 'text/html'}) response.end(html)})app.post('/', function(request, response) { console.log('POST /') console.dir(request.body) response.writeHead(200, {'Content-Type': 'text/html'}) response.end('thanks')})port = 3000app.listen(port)console.log(`Listening at http://localhost:${port}`)
