我无法从简单的表单中获取值。它有 2 个文件：
APP.jsFORM.ejsAPP.jsconst http = require('http');
const express = require("express");
const S1_APP = express();
const ejs = require("ejs");
const bodyParser = require("body-parser");
S1_APP.use(bodyParser.urlencoded({ extended: false }));
S1_APP.set('view engine', 'ejs');//template engine
S1_APP.get("", function (req, res) {
res.render('FORM.ejs');
});
S1_APP.post("/",function(req, res) {
// here I need to read the value (myvalue 1 or 2)
// that is send via the form in FORM.ejs
// I have tried req.body, that is empty
// I have tried req.value, that is undefined
});
S1_APP.listen(8080, function (err) {
if (err) console.log(err);
console.log("Server listening on PORT 8080");
});
FORM.ejs<html lang="en" >
<head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"></head>
<body>
<form method="POST" action="/">
<button type="submit" value="myvalue1" >POST 1</button>
<button type="submit" value="myvalue2" >POST 2</button>
</form>
</body>
</html>
您需要添加
name <button name="control1" type="submit" value="myvalue1" >POST 1</button>
<button name="control2" type="submit" value="myvalue2" >POST 2</button>
参见：
name元素的名称。例如服务器用来识别 表单提交中的字段。
