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 = `

Name:

`

response.writeHead(200, {'Content-Type': 'text/html'})

response.end(html)

}

})

const port = 3000

const 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 = `

Name:

`

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 = 3000

app.listen(port)

console.log(`Listening at http://localhost:${port}`)
