我做了一些研究，我仍然不知道这里发生了什么。谷歌有无关的搜索结果或给定的错误代码/消息。
这是我的角度控制器，只需基于api代码和ng-file上传的ng-file上传样本。
var app = angular.module('fileUpload', ['ngFileUpload']);
app.controller('MyCtrl', ['$scope', 'Upload', '$timeout', function ($scope, Upload, $timeout) {
console.log("Hey ho from controller");
$scope.uploadFiles = function (files) {
$scope.files = files;
if (files && files.length) {
console.log(files);
Upload.upload({
url: 'api/data/check',
data: {
files: files
}
}).then(function (response) {
$timeout(function () {
$scope.result = response.data;
console.log(response);
});
}, function (response) {
console.log(response);
if (response.status > 0) {
$scope.errorMsg = response.status + ': ' + response.data;
console.log(response);
}
}, function (evt) {
console.log(response);
$scope.progress =
Math.min(100, parseInt(100.0 * evt.loaded / evt.total));
});
}
};
}]);
这是我在服务器端编写的代码。
app.post('/api/data/check', merchants_offer_upload.single('files'), function (req, res, next) {
console.log(req.body.merchantid);
console.log("we are here");
// res.json({status: 0, picarray: array_pic});
});
我也试过这个，我希望这些一次上传所以我想使用数组上传功能
app.post('/api/data/check', merchants_offer_upload.array('files'), function (req, res, next) {
console.log(req.body.merchantid);
console.log("we are here");
// res.json({status: 0, picarray: array_pic});
});
这是完整的存储代码 - 服务器
var merchant_storage = multer.diskStorage({
destination: function (req, file, cb) {
console.log("Multer Part 1 Bitch!")
merchant_id = req.params.merchantid;
console.log(merchant_id);
console.log('merchant_id : ', merchant_id);
mkdirp(__dirname + '/images/offers/' + merchant_id, function (err) {
console.log(__dirname);
if (err) console.error(err)
cb(null, __dirname + '/images/offers/' + merchant_id);
console.log("heeeee 1");
});
},
filename: function (req, file, cb) {
console.log("Multer Part 2");
var f = Date.now()+'_'+file.originalname;
cb(null,Date.now() + f)
array_pic.push(f);
console.log(f);
console.log(file.originalname);
}
})
var merchants_offer_upload = multer({ storage: merchant_storage });
现在不好的部分。错误！
选择要上载的文件时会引发错误。

我必须添加一件事，而不是单个console.log部分打印在 控制台 - 来自服务器端，来自控制器的控制台 前端打印正确。
这是我在控制器端收到的错误消息

答案 0 :(得分：0)
答案是multer不接受ng-upload模块中的数组。
@mscdex在其他帖子上给出了答案。Multer not accepting files in array format gives 'Unexpected File Error'
