我使用角度文件上传,以前在我使用Laravel Lumen作为后端时工作但是我已经移动到Node并且无法返回上传的文件内容。
FRONT END ANGULAR
$scope.upload = Upload.upload({
url: ENV.apiEndpoint + '/upload',
method: 'POST',
data: {
fname: $scope.fname
},
file: file
}).progress(function(evt) {
}).success(function(data, status, headers, config) {
});
BACK END NODE
上传/ index.js
'use strict';
var express = require('express');
var controller = require('./upload.controller');
var router = express.Router();
var multer = require('multer');
var storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, './my-uploads');
},
filename: function (req, file, cb) {
cb(null, file.fieldname + '-' + Date.now());
}
})
var upload = multer({ storage: storage });
router.post('/', upload.single('file'), controller.index);
module.exports = router;
上传/ upload.controller.js
'use strict';
var _ = require('lodash');
var db = require('../../db');
var https = require('https');
var Q = require('q');
var fs = require('fs');
var multer = require('multer');
exports.index = function(req, res, next) {
console.log(req.files.file);
res.status(204).end();
};
旧Laravel Lumen请求
public function data(Request $request) {
$path_parts = pathinfo($_FILES["file"]["name"]);
$extension = $path_parts['extension'];
$contents = file_get_contents( $_FILES['file']['tmp_name'] );
return response()->json(['type'=> $extension, 'content'=> $contents]);
}
我要做的就是上传文件,但只将文件的内容再次返回到前端我不希望存储文件。

这里有一个例子,你有几个错误。看看
var storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, 'public/images/banks')
},
filename: function (req, file, cb) {
crypto.pseudoRandomBytes(16, function (err, raw) {
cb(null, raw.toString('hex') + path.extname(file.originalname));
});
}
});
var upload = multer({storage: storage});
router.post('/uploadImage', upload.single('file'), function (req, res, next) {
if(!req.file) {
res.status(400);
res.send({error: 'No se pudo subir el archivo'});
}
res.send({filename: req.file.filename});
});
