当我尝试以我的玉形式输入数据时,我收到错误消息,指出它为空。有人可以帮我弄清问题是什么吗?
app.js
var express = require('express');
var pg = require('pg');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var app = express();
var conString = "postgres://abc:123@localhost/abc";
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));
// development only,
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
//app.get('/', routes.index);
app.get('/', function (req, res) {
res.render('index',
{ title : 'Home' }
)
});
app.get('/users', user.list);
app.post('/', function(req, res){
var header = req.param('header', null); // second parameter is default
var body = req.param('body', null);
console.log(header);
console.log(body);
pg.connect(conString, function(err, client, done, request, response) {
client.on('drain', client.end.bind(client));//stänger av när alla queries är klara
client.query("INSERT INTO post(member_id, title, body) VALUES ('1', $1, $2)", [header, body], function(err, result){
if (err) {
console.log(err);
}
else{
res.send("success!");
}
});
});
});
http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
index.jade
extends layout
block content
h1= title
p Welcome to #{title}
form(action='/',method='post')
input(type='text',id='header',placeholder='header')
input(type='text',id='body',placeholder='body')
input(type='submit',name='submit',value='Submit')
layout.jade
doctype html
html
head
title= title
link(rel='stylesheet',href='/stylesheets/style.css')
body
block content
p whaddup
然而,如果我使用curl --verbose -d 'header=abcd&body=1234' http://localhost:3000
它可以正常工作,所以我相当肯定它是玉部分,但我不知道什么是错的。我是nodejs的新手,所有:)
提前谢谢。
答案 0 :(得分:1)
这是与数据一起提交的表单控件的name
,而不是id
。实际上,您的表单提交的唯一值是submit
按钮。
相反它应该是这样的:
input(type='text', name='header', placeholder='header')
input(type='text', name='body', placeholder='body')
