【问题描述】：
请帮我解决我长期以来一直在努力解决的错误。因此，我也无法将数据添加到我的数据库中。 任何帮助将不胜感激。
这是我的 index.js 代码
const express = require('express');
const app = express();
const routes = require('./routes');
const path = require('path');
const fileUpload = require('express-fileupload');
const bodyParser = require('body-parser');
const session = require('express-session');
const auth = require('./routes/auth');
const {
con,
sessionStore
} = require('./config/db');
const fs = require('fs');
require('dotenv').config({
path: path.join(__dirname, '.env')
});
const port = process.env.PORT || 3000;
// parse application/json
app.use(bodyParser.json())
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({
extended: false
}));
//static files
app.use(express.static('public'))
app.use('/css' , express.static(__dirname + 'public/css'))
app.use('/imgs' , express.static(__dirname + 'public/imgs'))
var sess = {
secret: 'keyboard cat',
store: sessionStore,
cookie: {
httpOnly: false,
},
resave: false,
saveUninitialized: false
}
app.use(session(sess));
app.use(fileUpload());
//set views
app.set('view engine' , 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use(require('connect-flash')());
app.use((req, res, next) => {
res.locals.messages = require('express-messages')(req, res);
next();
});
app.get('/', (req,res) =>{
res.render('index22')
})
app.get('/login', (req, res) => {
res.render('login');
});
let s;
const loginRequired = (req, res, next) => {
if (req.session.username) {
s = req.session;
next();
} else {
res.redirect('/auth/login');
}
}
app.get('/new', loginRequired, routes.new);//call for main index page
app.post('/new', loginRequired, routes.new);//call for signup post
app.get('/show/:username', loginRequired, routes.show);
app.use('/auth', auth);
app.listen(port, () => console.log(`listening on http://${process.env.HOST}:${port}`));
这是我的 routes.js 代码
const {
con,
sessionStore
} = require('./config/db');
exports.new = function(req, res){
message = '';
if(req.method == "POST"){
const post = req.body;
const username= post.username;
const title= post.title;
const state= post.state;
const category= post.category;
const description= post.description;
if (!req.files)
return res.status(400).send('No files were uploaded.');
const file = req.files.uploads;
const img_name=file.name;
if(file.mimetype == "images/jpeg" ||file.mimetype == "images/png"||file.mimetype == "images/gif" ){
file.mv('public/imgs/uploads/'+file.name, function(err) {
if (err)
return res.status(500).send(err);
const sql = "INSERT INTO `nt_data`(`username`,`title`,`state`,`category`, `images` ,`description`) VALUES ('" + username + "','" + title + "','" + state + "','" + category + "','" + img_name + "','" + description + "')";
const query = con.query(sql, function(err, result) {
res.redirect('show/'+result.insertUsername);
});
});
} else {
message = "This format is not allowed , please upload file with '.png','.gif','.jpg'";
res.render('new.ejs',{message: message});
}
} else {
res.render('new');
}
};
exports.show = function(req, res){
let message = '';
const username = req.params.username;
const sql="SELECT * FROM `nt_data` WHERE `username`='"+username+"'";
con.query(sql, function(err, result){
if(result.length <= 0)
message = "show not found!";
res.render('show.ejs',{data:result, message: message});
});
};
这是我的 new.ejs 代码的一部分
<body>
<h1 class="mt-5" id="h1">New Post</h1>
<hr class="w-50">
<div class="container mt-3">
<form action="/" method="POST" class="was-validated" enctype="multipart/form-data">
<% if (message.length > 0) { %>
<div class="alert alert-success col-sm-12"><%= message %></div>
<% } %>
<div class="row">
<div class="col-6">
<select name="state" class="custom-select mb-3">
<option>Select Sate</option>
<option value="Sikkim">Sikkim</option>
<option value="Manipur">Manipur</option>
<option value="Mizoram">Mizoram</option>
</select>
</div>
请帮我解决这个非常重要的错误。 谢谢

您不处理
/的 POST 请求。您的意思是向/new发帖吗？
