javascript - req.body.object 未定义

Question

req.body.object 不断返回未定义的值。

我导入了主体解析器，但当我调用 console.log() 时它仍然是未定义的

//javascript
const express = require('express');
var bodyParser = require('body-parser'),
  const app = express();

app.use(bodyParser.urlencoded({
  extended: true
}))
app.use(express.static('public'));

app.post('/demos/net', function(req, res) {
  console.log(req.body.object)
  res.render('demos/demos.ejs')
});

var port = process.env.PORT || 8081;

var server = app.listen(port, function() {
  console.log('Server running at http://127.0.0.1:' + port + '/');
});

<form class="form" action="/demos/net" method="POST">
  <button type="submit" id="net-start" class="btn btn-success ">Go</button>
</form>
<input type="number" class="form-control" placeholder="100" name="object">

req.body.object 被记录为未定义

Answer 1

输入元素超出表单范围。您必须将其移动到表单内或通过 form 属性将其与表单关联:form="insert-id-of-form"

<input type="number" form="insert-id-of-form" class="form-control" placeholder="100"name="object">
