express
我想通过点击一个HTML按钮在服务器上创建一个文件。
srcServer.js
:
var express = require('express');
var path = require('path');
var open = require('open');
var fs = require('fs');
var port = 3000;
var app = express();
app.get('/', function(req, res){
res.sendFile(path.join(__dirname, '../src/index.html'));
});
app.post('/', function(request, respond) {
fs.writeFile('message.txt', 'Hello Node.js', (err) => {
if (err) throw err;
console.log('The file has been saved!');
});
});
app.listen(port, function(err){
if(err){
console.log(err);
}else{
open('http://localhost:' + port);
}
});
这是
index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
</head>
<body>
<h2>The Button Element</h2>
<form action="" method="post">
<button name="foo" value="send">Send</button>
</form>
</body>
</html>
我很确定问题是我如何处理HTML按钮,但我不知道更好。单击时收到的错误是:
Cannot POST /
.
