安装万用表:https://github.com/expressjs/multer
npm install --save multer
在 MyModel.js 中
var multer = require('multer');
var fs = require('fs');
module.exports = function (MyModel) {
var uploadedFileName = '';
var storage = multer.diskStorage({
destination: function (req, file, cb) {
// checking and creating uploads folder where files will be uploaded
var dirPath = 'client/uploads/'
if (!fs.existsSync(dirPath)) {
var dir = fs.mkdirSync(dirPath);
}
cb(null, dirPath + '/');
},
filename: function (req, file, cb) {
// file will be accessible in `file` variable
var ext = file.originalname.substring(file.originalname.lastIndexOf("."));
var fileName = Date.now() + ext;
uploadedFileName = fileName;
cb(null, fileName);
}
});
MyModel.upload = function (req, res, cb) {
var upload = multer({
storage: storage
}).array('file', 12);
upload(req, res, function (err) {
if (err) {
// An error occurred when uploading
res.json(err);
} else {
res.json(uploadedFileName);
}
});
};
MyModel.remoteMethod('upload', {
accepts: [{
arg: 'req',
type: 'object',
http: {
source: 'req'
}
}, {
arg: 'res',
type: 'object',
http: {
source: 'res'
}
}],
returns: {
arg: 'result',
type: 'string'
}
});
};
前端 - 我使用 AngularJS,因此遵循 -https://github.com/nervgh/angular-file-upload
还有其他这样的指令可以使用
附: - 根据你的评论 -Actually Our Problem is that , we need to upload a File from Client Side and Store this File in Database , But Before save in DB , we need to get files on Server side , if we get Files on Server side via Post API than we can easily store file in DB
无法为您提供确切的解决方案,但使用上述方法文件将上传到您的/client/uploads
文件夹,一旦上传,您就可以控制如何处理文件,一旦一切完成,最终删除它(可选)
