使用DropzoneJs使用Multer将文件上传到Node服务器时,我无法保存文件,也无法在控制台的req.file
或req.files
对象中看到任何内容。
这里是HTML,上面撒了EJS:
<div class="container">
<div class="row dropzone_input_div">
<h1 class="new_event_header">Add Your photos for <%= event.title %></h1>
<div>
<form class="dropzone needsclick dz-clickable" action="/testmedia" id="dropzoneFileUpload" name="mediaFile" enctype="multipart/form-data">
<input type="text" value="<%= event._id %>" hidden name="id">
</form>
</div>
</div>
<div class="row">
<div class="dropzone_preview">
</div>
</div>
</div>
这是Dropzone JS文件:
Dropzone.options.dropzoneFileUpload={
paramName: "media",
parallelUploads: 30,
uploadMultiple: true,
autoProcessQueue: true
}
这是我正在使用的节点/ Express /路由器:
const multer = require('multer');
// const upload = multer({dest:'uploads/'})
const async = require('async');
const dotenv = require('dotenv');
require('dotenv').config({silence:true});
const router = express.Router();
//Add Mongo Models to use Mongoose
const { Event, User, Moments, Instant } = require("../models");
const b2 = new B2({
accountId: process.env.B2_MASTER_APPLICATION_KEY,
applicationKey: process.env.B2_WRITE_APPLICATION_KEY
});
//router.use('/testmedia',upload.single('uploadedFile'))
router.use(multer({dest: 'uploads/'}).single('file'));
const uploads = (req,res,next) => {
console.log("hit uploads yall!");
console.log(req.file);
next();
}
const testMedia = (req,res) => {
console.log("hit testMedia route");
res.send("File uplaoded!")
}
我的console.log文件看起来像这样...
hit uploads yall!
undefined
hit testMedia route
POST /testmedia 200 5.603 ms - 14
任何提示为什么我看不到文件?它们不会保存到我的服务器(Ubuntu)上的/ uploads文件中,并且始终在控制台中显示undefined
吗?
答案 0 :(得分:0)
我的朋友Eli,帮我解决了这个问题...
我采取的步骤:
testmedia
请求file[0]:
(binary)
的表单数据在我的路线文件中,我使用了
const express = require('express');
const passport = require('passport');
const crypto = require('crypto');
const flash = require('express-flash');
const xoauth2 = require('xoauth2');
const B2 = require('backblaze-b2');
const async = require('async');
const multer = require('multer');
const { User } = require("../models");
const {
testMedia
} = require('../controllers/backblaze.controller')
const router = express.Router();
//*******************Middleware for Backblaze routes******************
const storeImage = multer.diskStorage({
destination: (req,file,cb) => {
cb(null, 'uploads/')
},
filename: (req,file,cb)=> {
cb(null,file.fieldname + '-'+ Date.now())
}
});
const upload = multer({storage:storeImage})
//*****THE ANSWER IS BELOW THIS LINE IN THE .single() method*****
router.post("/testmedia", upload.single('file[0]'), testMedia);
//router.post("/testmedia", upload.any(), testMedia);
我需要的功能在testMedia
的另一个文件夹中,看起来像这样
const testMedia = (req,res) => {
console.log("hit testMedia route");
res.send("File uplaoded!")
}
我还没有对文件做任何事情,但这是我的解决方案,体系结构有些不同,但是这个问题是关于上述步骤以及通过浏览器获取解决方案并在{{1 }}中的方法
