接受POST请求的Node.js服务器

我正在尝试允许javascript与Node.js服务器通信。

POST请求（Web浏览器）

var http = new XMLHttpRequest();
var params = "text=stuff";
http.open("POST", "http://someurl.net:8080", true);

http.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
http.setRequestHeader("Content-length", params.length);
http.setRequestHeader("Connection", "close");

alert(http.onreadystatechange);
http.onreadystatechange = function() {
  if (http.readyState == 4 && http.status == 200) {
    alert(http.responseText);
  }
}

http.send(params);

现在Node.js服务器代码看起来是这样的，在它被用于GET请求之前，我不知道如何使它与POST请求一起工作。

服务器（节点. js）

var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;

  if (queryData.text) {
    convert('engfemale1', queryData.text, response);
    response.writeHead(200, {
      'Content-Type': 'audio/mp3', 
      'Content-Disposition': 'attachment; filename="tts.mp3"'
    });
  } 
  else {
    response.end('No text to convert.');
  }
}).listen(8080);

下面的代码展示了如何从HTML表单中读取值。正如@pimvdb所说，您需要使用request.on（'data'...）来捕获表单主体的内容。

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 = 3000
const host = '127.0.0.1'
server.listen(port, host)
console.log(`Listening at http://${host}:${port}`)

如果您使用类似Express.js和Bodyparser的代码，那么它将如下所示，因为Express将处理请求。body concatenation

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')
})

const port = 3000
app.listen(port)
console.log(`Listening at http://localhost:${port}`)

在nodejs中接收POST和GET请求：
1）.服务器

var http = require('http');
    var server = http.createServer ( function(request,response){

    response.writeHead(200,{"Content-Type":"text\plain"});
    if(request.method == "GET")
        {
            response.end("received GET request.")
        }
    else if(request.method == "POST")
        {
            response.end("received POST request.");
        }
    else
        {
            response.end("Undefined request .");
        }
});

server.listen(8000);
console.log("Server running on port 8000");

2).委托单位：

var http = require('http');

var option = {
    hostname : "localhost" ,
    port : 8000 ,
    method : "POST",
    path : "/"
} 

    var request = http.request(option , function(resp){
       resp.on("data",function(chunck){
           console.log(chunck.toString());
       }) 
    })
    request.end();
