FileUploader.js:479 POST http://localhost:3000/404 (Not Found)
FileUploader.js:479 POST http://localhost:3000/404（未找到）
I understand that FileUploader.js can't find upload.php file, but I put it to the root folder and provided path:
我知道 FileUploader.js 找不到 upload.php 文件，但我把它放到了根文件夹并提供了路径：

Where is my mistake? I appreciate any help.
我的错误在哪里？我很感激任何帮助。
I used this exampleand take out my upload.php at all, fixed server/app.j s and controller.js , but still getting same error
我使用了这个例子并删除了我的 upload.php，修复了 server/app.js 和 controller.js ，但仍然得到同样的错误

I put this code into routes.js
我把这段代码放到了 routes.js
var multer = require('multer');
var storage = multer.diskStorage({
destination: function (req, file, callback) {
callback(null, './upload');
},
filename: function (req, file, callback) {
callback(null, file.fieldname + '-' + Date.now());
}
});
var upload = multer({ storage : storage}).single('test');
router.post('/',function(req,res){
upload(req,res,function(err) {
if(err) {
return res.end("Error uploading file.");
}
res.end("File is uploaded");
});
});
Now post returns 200, but nothing appears in folder "upload". Are there any ideas, what's wrong now?
现在 post 返回 200，但文件夹“upload”中没有任何内容。有什么想法吗，现在出了什么问题？

The error is POST http://localhost:3000/ 404 (Not Found)
错误是 POST http://localhost:3000/ 404 (Not Found)
You don't have a post route for /
你没有邮寄路线 /
You can create one like so:
您可以像这样创建一个：
router.post('/', function(req, res) {
// do something w/ req.body or req.files
});
router.post('/', function(req, res) {
// do something w/ req.body or req.files
});
But also, I recommend using eitherexpress or upload.php
但同时，我建议使用任何明示或upload.php的
To use express, you'll need to update your angular FileUploader url as well
要使用 express，您还需要更新有角度的 FileUploader url
