我正在尝试将form data
保存到MongoDb
,其中还包含image file upload
。我使用Jquery form serialize
将此数据发送到server
。其余数据将保存到数据库,但不会保存到图像中。我想这需要一些特殊的待遇。我怎样才能做到这一点?注意:我希望能够将其与所有表单数据一起发送
这是我的HTML部分:
<!-- SIGNUP for USERS and ADMIN -->
<div id="pageSignup" class="page popup">
<div class="wrapper">
<h3>SIGNUP</h3>
<form class="form" id="frmSignup">
<input type="text" id="txtEmailorPhoneNumber" name="txtEmailorPhoneNumber" placeholder="Mobile number or Email" required>
<input type="text" name="txtName" placeholder="Name" required>
<input type="text" name="txtLastName" placeholder="Lastname" required>
<input type="password" name="txtPassword" placeholder="Password" required>
<div class="lblFileUpload">
<p>Select your picture:</p>
<input type="file" name="fileUserImage" required>
</div>
<button type="button" class="btnShowPage btnForm" id="btnSignupForm">Signup</button>
<div class="lblFormExtention">
<p class="pyesAccount">Already have an account?</p>
<button type="button" class="btnShowPage" id="btnLogin" data-showThisPage="pageLogin">Login</button>
</div>
</form>
<h3 class="lblErrorMessage" id="lblSignupErrorMessage"></h3>
</div>
</div>
这是jquery序列化部分:
$('#btnSignupForm').click(function () {
console.log('btn signup user clicked')
var oForm = $("#frmSignup").serialize()
console.log("oForm", oForm)
var sUrl = 'save-user/'
console.log("sUrl ", sUrl);
$.post(sUrl, oForm, function (uData) {
console.log('SUCCESS')
})
})
这是我的server.js:
var express = require('express')
var app = express()
var formidable = require('express-formidable');
app.use(formidable());
app.use(express.static(__dirname + '/public'));
var fs = require('fs')
var mongo = require('mongodb').MongoClient
global.db = null
var sDatabasePath = 'mongodb://localhost:27017/webshop'
global.mongoId = require('mongodb').ObjectID
/**************************************************/
var user = require(__dirname + '/user.js')
/**************************************************/
app.get('/shopaholic', (req, res) => { res.sendFile(__dirname + '/shopaholic.html') })
mongo.connect(sDatabasePath, (err, db) => {
if (err) {
console.log('ERROR 003 -> Cannot connect to the database')
return false
}
global.db = db
console.log('OK 002 -> Connected to the database')
return true
})
/**************************************************/
app.post('/save-user', (req, res) => {
//var sName = req.fields.userName
//console.log("sName ", sName)
user.saveUser(req.fields, (err, jResult) => {
if (err) {
console.log(jResult)
res.send('ERROR')
return
}
console.log(jResult)
res.send('OK')
return
})
})
/**************************************************/
app.listen(3000, (err) => {
if (err) {
console.log('ERROR 001 -> Cannot listen to port 3000')
return false
}
console.log('OK 000 -> Server listening to port 3000')
})
最后是我的user.js:
var user = {}
/**************************************************/
user.saveUser = (jUserData, fcallback) => {
var jUser = { "userName": jUserData.txtEmailorPhoneNumber, "firstName": jUserData.txtName, "lastName": jUserData.txtLastName, "password": jUserData.txtPassword, "image": jUserData.fileUserImage }
global.db.collection('users').insertOne(jUser, (err, jResult) => {
if (err) {
var jError = { "status": "error", "message": "ERROR -> user.js -> 001" }
console.log(jError)
return fcallback(true, jError)
}
var jOk = { "status": "ok", "message": "user.js -> saved -> 000" }
console.log(jOk)
return fcallback(false, jOk)
})
}
/**************************************************/
module.exports = user

我建议您使用 multer 模块处理文件上传,并仅在您的mongodb数据库中保存图片的路径/网址,并告诉我们是否已知道你遇到这种方法的任何问题。我很乐意提供帮助。
