我在nodejs应用程序中使用multer来上传文件。前端部分使用angularjs。单击上传图像后,在控制台上,我得到的答案不确定。谁能帮助我解决问题。
我在这里粘贴代码。
server.js
var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var bodyParser = require('body-parser');
var path = require('path');
var fs = require('fs');
var spawn = require('child_process').spawn;
var multer = require('multer');
var storage = multer.diskStorage({
destination:function(req,file,cb){
cb(null,'public/upload/');
},
filename:function(req,file,cb){
cb(null,file.originalname);
}
});
var upload = multer({storage: storage});
app.set('views', __dirname + '/views');
app.use(bodyParser.json());
var urlencodedParser = bodyParser.urlencoded({ extended: true });
app.use(express.static('public'));
app.get('/',function(req,res){
res.render('index',{ title: 'Upload image' });
});
app.post('/loadImage',upload.any(),function(req, res) {
console.log(req.files);
console.log("Inside post");
});
http.listen(8080,'0.0.0.0',function(){
console.log('listening on 8080');
})
这是我的app.js angularjs代码
var app = angular.module('app',['ui.router','ui.bootstrap','ngAnimate']);
$scope.img={};
app.controller('Ctrl',function ($scope,$http){
$scope.loadImage = function(){
$http.post('/loadImage',$scope.img).success(function(data){
console.log('Posted successfully');
}).error(function(data){
console.error('error');
})
};
还有我的HTML代码:
<form ng-submit="loadImage()" enctype="multipart/form-data">
<input type="file" name="file" multiple />
<input type="submit" value="Upload Image" name="submit" />
</form>
在控制台上,我得到了未定义和内部帖子。在浏览器控制台上,我已经成功发布了,请问有人可以帮助我解决此问题。而不是未定义,我应该获取已加载的文件信息。
最佳答案
这就是我用Multer上传图像的方式
var multer = require('multer');
exports.loadImage = function (req, res) {
var upload = multer({
inMemory: true,
limits: {fileSize: 1024 * 1024 }
}).single('newPicture');
upload(req, res, function (uploadError) {
if (uploadError) {
return res.status(400).send({ message: 'errorUploadingPicture' });
}
else {
var profileImage = 'No data uploaded';
// this is where the photo data is
if (req.file && req.file.buffer) {
profileImage = req.file.buffer;
}
return res.json(profileImage );
}
});
};
关于html - 从multer返回未定义的答案,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/39240825/
