[英]how to upload the image to folder using nodejs and save the path into mongodb?
我想使用angularjs或html5,Express.jsjs和mongodb.image上傳圖片。我按照教程進行操作,但是我無法將圖片上傳到文件夾,請有人幫我做。下面給出了我的架構代碼
my schema
var UserSchema = new Schema({
UserName: {
type: String,
default: '',
trim: true,
},
Avatar: {
type: String,
default: '',
trim: true
},
Email: {
type: String,
default: '',
trim: true
},
Password: {
type: String,
default: '',
trim: true
}
});
我想上傳帶有用戶詳細信息的圖像
<form action="/upload" method="post" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="Avatar" id="fileToUpload">
<input type="text" name="UserName" id="name">
<input type="email" name="Email" id="email">
<input type="password" name="Password" id="password">
<input type="submit" value="Upload File" name="submit">
</form>
我想將圖像存儲到某個文件夾(如上載和路徑)的另一件事應該存儲在database.help我,謝謝您的回復
您可以使用nodejs強大的fs-extra模塊創建用於在應用程序中存儲圖像的文件夾。 嘗試這個
var fs = require('fs-extra');
var formidable = require('formidable');
var EmpDetail = require('../models/employee.model.js');//This line means that I am having my schema code.
var util = require('util');
app.route('/upload').post(function(req,res){
res.json({success:true});
var empData = new EmpDetail();//Here I created object to call my schema values.
var form = new formidable.IncomingForm();
console.log(req.body,'req.body');
form.parse(req,function(err,fields,files){
console.log('dfgbfbf');
util.inspect({fields: fields, files: files});
});
form.on('field',function(name,value){//This means your html input fields
console.log('fields',name,value);
if(name == 'fullName'){
console.log('here',value);
empData.fullName = value;
}
if(name == 'fatherName'){
empData.fatherName = value;
}
if(name == 'dt'){
empData.DOB = value;
}
});
form.on('file',function(field, file){//This means on click of file it gets that file.
console.log(file.name,'hjgjg');
var temp = file.path;
console.log(temp,'temp',file.name);
var fileName = file.name;
var fileName = file.name;
var location = 'images/';
var cpLocation = 'empDetails/images/';
empData.imgSize = file.size;
empData.imgType = file.type;
empData.picFile = location+fileName;//Here PicFile is name of Avatar in model
fs.copy(temp,cpLocation+fileName ,function(err){//This means it create a folder and name of the image in your app.
if(err)
{
console.log(err);
}
});
});
form.on('end',function(fields, files){
empData.save(function(err,resobj){
if(err)
{
throw err;
}
});
});
});
有一個名為skipper的小型節點模塊,可以處理文件上傳。 使用以下命令安裝它: npm install skipper --save
。 由於您正在使用Express,因此您的主文件應如下所示:
var express = require('express');
var app = express();
app.use(require('skipper')());
app.post('/upload', function (req, res) {
req.file('avatar').upload(function (err, uploadedFiles) {
if (err) return res.send(500, err);
return res.json({
message: uploadedFiles.length + ' file(s) uploaded successfully!',
files: uploadedFiles
});
});
});
而且您的html表單應類似於:
<form action="/upload" method="post" enctype="multipart/form-data">
Select file to upload:
<input type="file" name="avatar" id="fileToUpload">
<input type="submit" value="Upload File" name="submit">
</form>
注意:此路由將返回json對象。
