我有一个非常简单的html表单,并且表达服务器,但我无法使路由工作。我总是得到“不能发帖”的消息。我错过了什么?
var express = require('express');
var bodyparser = require('body-parser');
var path = require('path');
var app = express();
app.use(express.static("public"));
app.use(express.bodyParser());
app.get("/", function(req, res){
res.sendFile(path.join(__dirname+"/index.html"));
});
app.post("/sendform", function(req, res){
res.send('You sent the name "' + req.query.user + '".');
});
app.listen(3000, function(){
console.log("Server is running at port: 3000");
});
<form method="post" action="http://localhost:3000/sendform">
<input type="text" name="username" />
<input type="submit" value="küldés" />
</form>

使用express 4.15.3,你必须使用身体解析器。 我将您的代码更改为此,我可以发布到它:
var express = require('express');
var bodyParser = require('body-parser');
var path = require('path');
var app = express();
app.use(express.static("public"));
//app.use(express.bodyParser());
app.use(bodyParser.json({
limit: "10mb"
}));
app.use(bodyParser.urlencoded({
limit: "10mb",
extended: true
}));
app.get("/", function (req, res) {
res.sendFile(path.join(__dirname + "/index.html"));
});
app.post("/sendform", function (req, res) {
res.send('You sent the name "' + req.query.user + '".');
});
app.listen(3000, function () {
console.log("Server is running at port: 3000");
});
