Question

可能是一个愚蠢的问题，但也许有人可以帮助我。

使用multer上传文件并表达后，上传文件的网址是uploads/？

var storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, 'uploads/')
    }
});

如果它是一张图片，我该如何链接到它： http://localhost:3000/uploads/image.jpg？

我应该将上传的文件放在公共目录中吗？

感谢

这就是我为expressjs设置Multer的方法。首先，如果要保留原始文件名，则必须覆盖重命名功能。然后，您必须将uploads文件夹移动到公用文件夹。

// this uploads a single input[file] field called 'image'
var express = require('express'),
    multer = require('multer'),
    upload = multer({
        storage: multer.diskStorage({
            destination: 'public/images/uploads/',
            filename: function(req, file, cb) {
                // this overwrites the default multer renaming callback
                // and simply saves the file as it is
                cb(null, file.originalname)
            }
        })
    }),
    router = express.Router()

// add route
router.post('/uploadimage', upload.single('image'), function(req, res, next) {
    if (!req.file) return next(new Error('Select a file!'))
    // be careful here as the upload path has 'public' at the start 
    // which is the static mounted directory so doesn't show
    // here the path is build manually
    var imagePath = '/images/uploads/' + req.file.filename;
    res.end('<img src=" + imagePath + " />')        
})

另外，您可以将默认上传路径保留为/uploads并将其安装为静态文件夹

  // Mount uploads
  app.use(express.static(path.resolve('./uploads')));

在您的案例中设置静态磁盘位置＆＃39;上传＆＃39;文件夹应该是静态的
