【问题描述】：
客户端：
我已经使用 AngularJS 和 NodeJS 完成了文件上传，它正在工作，但是在上传文件时我需要将“名称”和“电子邮件”传递给服务器。
服务器端：
将文件上传到文件夹后，我需要将文件路径、名称和电子邮件保存到数据库中。我该怎么做？
angular.module('fileUpload', ['ngFileUpload'])
.controller('MyCtrl',['Upload','$window',function(Upload,$window){
var vm = this;
vm.submit = function(){ //function to call on form submit
if (vm.upload_form.file.$valid && vm.file) { //check if from is valid
vm.upload(vm.file); //call upload function
}
}
vm.upload = function (file) {
console.log(vm.name);
console.log(vm.email);
Upload.upload({
url: 'http://localhost:3000/upload', //webAPI exposed to upload the file
data:{file:file} //pass file as data, should be user ng-model
}).then(function (resp) { //upload function returns a promise
if(resp.data.error_code === 0){ //validate success
$window.alert('Success ' + resp.config.data.file.name + 'uploaded. Response: ');
} else {
$window.alert('an error occured');
}
}, function (resp) { //catch error
console.log('Error status: ' + resp.status);
$window.alert('Error status: ' + resp.status);
}, function (evt) {
console.log(evt);
var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
console.log('progress: ' + progressPercentage + '% ' + evt.config.data.file.name);
vm.progress = 'progress: ' + progressPercentage + '% '; // capture upload progress
});
};

<h1>Angular Node File Upload</h1>
<form ng-controller="MyCtrl as up" name="up.upload_form">

</body>
</html>后端代码：
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var multer = require('multer');
app.use(function(req, res, next) { //allow cross origin requests
res.setHeader("Access-Control-Allow-Methods", "POST, PUT, OPTIONS, DELETE, GET");
res.header("Access-Control-Allow-Origin", "http://localhost");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
/** Serving from the same express Server
No cors required */
app.use(express.static('../client'));
app.use(bodyParser.json());
var storage = multer.diskStorage({ //multers disk storage settings
destination: function (req, file, cb) {
cb(null, './uploads/');
},
filename: function (req, file, cb) {
var datetimestamp = Date.now();
cb(null, file.fieldname + '-' + datetimestamp + '.' + file.originalname.split('.')[file.originalname.split('.').length -1]);
}
});
var upload = multer({ //multer settings
storage: storage
}).single('file');
/** API path that will upload the files */
app.post('/upload', function(req, res) {
console.log(req.body);
upload(req,res,function(err){
if(err){
res.json({error_code:1,err_desc:err});
return;
}
res.json({error_code:0,err_desc:null});
});
});
app.listen('3000', function(){
console.log('running on 3000...');
});
我试过这样
Upload.upload({
url: 'http://localhost:3000/upload', //webAPI exposed to upload the file
data:{file:file, name:vm.name, email:vm.email} //pass file as data, should be user ng-model
})
后端
app.post('/upload', function(req, res) {
console.log(req.body);
console.log(req.file);
upload(req,res,function(err){
if(err){
res.json({error_code:1,err_desc:err});
return;
}
res.json({error_code:0,err_desc:null});
});
});

你是用Cloudinary上传文件吗，也可以看看你的上传方式
