Question

我现在已经关注了几次不同的在线尝试，并且我一直在为我的帖子数据而未定义，而console.log（JSON.stringify（req.body））也没有返回任何内容。所以我在某处出错了。 ..

HTML：

<input type="file" id="files" />
<div id="output"></div>

JS：

<!DOCTYPE HTML>
<html>
  <head>
    <title>Chat</title>
  </head>
  <body>
    <form action="/" method="post">
      <button>Close</button><br/><br/>
      <label for="username">Your Name: *</label><br/>
      <input id="username" type="text" value="" name="username" autocomplete="off" required="required" /><br/>
    <!--   <label for="email">Email: *</label><br/>
      <input id="email" value="" name="email_address" autocomplete="off" required="required" /><br/> -->
      <label for="phone">Phone:</label><br/>
      <input id="phone" value="" name="phone" autocomplete="off" /><br/>
      <label for="question">Question: </label><br/>
      <textarea id="question" name="question">
      </textarea required="required"><br/><br/>
      <button type="submit">Chat</button>
    </form>
  </body>
</html>

尝试使用express-fileupload包，您可以在req.body中获取数据

var app = require('express')();
var http = require('http').Server(app);
const fileUpload = require('express-fileupload')

app.use(fileUpload());

app.get('/', function(req, res){
    res.sendFile(__dirname + '/index.html');
});

app.post('/', function(req, res) {
var username = req.body.username;
res.send('<h1>Hello</h1> '+username);
});

http.listen(3000, function(){
  console.log('listening on *:3000');
});

使用Nodejs和body-parser发布表单数据
