Question

我如何处理通过curl上传的文件。我有快递js动作/路线

router.route('/images')    
  .post (function(req, res) {
       res.status(200);
       res.json({ message: 'file uploaded' });
    });

app.use('/api', router);

我尝试使用此命令上传文件 $ curl -v -F filedata=@image.jpg https://webapp.com/api/images

我回来了

在服务器日志中，我看到了

` at=info method=POST path="/api/images" host=webapp.herokuapp.com request_id=e6c18dc4-4a3f-4fe7-ab70-198a83c985c8 fwd="99.89.114.63" dyno=web.1 connect=1ms service=189ms status=200 bytes=229`

` 的问题

如何获取对实际文件（filedata）的访问权限并执行我想要的操作？提前谢谢。

经过一番研究，我遇到了connect-bus-boy。这就是我实现上传路径的方式。首先安装busboy npm install busboy然后在你的代码中实现这个......

  var busboy = require('connect-busboy');
  app.use(busboy()); 
//...

router.route('/images')    
  .post (function(req, res) {

    var fstream;
    req.pipe(req.busboy);
    req.busboy.on('file', function (fieldname, file, filename) {
        console.log("Uploading: " + (fieldname)); 
        fstream = fs.createWriteStream(__dirname + '/public/img/'+ filename);
        file.pipe(fstream);
        fstream.on('close', function () {
        res.status(200);
        res.json({ message: 'File uploaded' });

        });
    });


    });
