标签： javascript php angularjs node.js file-upload

我正在使用带上传功能的网络文件浏览器。我正在使用Angular File Upload指令和angular web file browser。

首先我已经下载了文件网页浏览器并进行了配置。

其次我已经下载了文件上传指令，并且一步一步完成了所有操作，我的页面工作正常

但是当我试图上传我正在上传的东西时

  

FileUploader.js：479 POST http://localhost:3000/ 404（未找到）

据我所知，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：

  var uploader = $scope.uploader = new FileUploader({
            url: 'upload.php'
        });

它的外观如下：

    }
  ]);

}());

我的错误在哪里？我感谢任何帮助。

我使用了这个example并取出了我的upload.php，修复了server / app.j和controller.js，但仍然出现同样的错误

更新

我将此代码放入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");
    });
});

现在帖子返回200，但文件夹“upload”中没有任何内容。有没有想法，现在有什么不对？

1 个答案:

答案 0 :(得分：4)

错误为POST http://localhost:3000/ 404 (Not Found)

您没有/

的邮寄路线

你可以这样创建一个：

router.post('/', function(req, res) { // do something w/ req.body or req.files });

但是，我建议使用 express或upload.php

要使用express，您还需要更新角度FileUploader网址
