以下是我在服务器端发布数据的HTML表单代码。
HTML代码:
<form action="/Device_Data" method="post">
<select name="deviceSelect" id="deviceSelect" class="selectdevice" type = "text" style="margin-top:1.5%">
<option value="" selected="selected">Choose Device</option>
<option value="Device1">Device 1</option>
<option value="Device2">Device 2</option>
<option value="Device3">Device 3</option>
<option value="Device4">Device 4</option>
<option value="Device5">Device 5</option>
<option value="Device6">Device 6</option>
<option value="Device7">Device 7</option>
<option value="Device8">Device 8</option>
</select>
<button id="Import" value="Import" class="button1" type="button" formenctype="text/plain">Import</button>
</form>
服务器代码:
var express = require('express');
//require the body-parser nodejs module
var bodyParser = require('body-parser');
var path = require('path');
var qs = require('querystring');
var app = express();
// var server = http.createServer(app);
//support parsing of application/json type post data
app.use(bodyParser.json());
//support parsing of application/x-www-form-urlencoded post data
app.use(bodyParser.urlencoded({ extended: false }));
app.post("/Device_Data", function (req, res) {
// result.entries contains entities matching the query
//res.setHeader('Content-Type', 'application/json');
console.log(req.body);
res.send(200, req.body);
});
输出:
{}

任何人都可以帮助我吗? 提前谢谢。
我只想打印req.body数据。

就像错误所说的那样,不推荐使用语法res.send(status, body):
。
更改以下代码:
res.send(200, req.body);
要:
res.status(200).send(req.body);

将按钮的type
更改为提交,然后从此按钮中移除formenctype
。
<button id="Import" value="Import" class="button1" type="submit">Import</button>
