上传的图像无法使用multer

我正在尝试使用express和multer上传图片。这是我用来上传图片的表单:

<form action="/uploadProfilePicture" method="POST" id="form-upload-profile-picture">
  <div class="row center">
      <div class="row">
          <input type="file" name="uploadProfilePicture" id="add-friend-search-input">
      </div>
      <div class="row">
          <button class="button-green-large" class="u-full-width" id="add-friend-search-submit">Upload</button>
      </div>
  </form>

这是我的后端:

var mkdirp           = require("mkdirp"),
    multer           = require("multer");

// MULTER CONFIGURATION
    var storage = multer.diskStorage({
    destination: function (req, file, cb) {
        //var code = JSON.parse(req.body.model).empCode;
        var dest = "/public/images";
        mkdirp(dest, function (err) {
            console.log(dest);
            if (err) cb(err, dest);
            else cb(null, dest);
        });
    },
    filename: function (req, file, cb) {
        cb(null, Date.now()+'-'+file.originalname);
    }
});

// POST ROUTE: Upload profile picture
app.post("/uploadProfilePicture", upload.any(), function(req, res) {
    console.log(req.body);
    res.send(req.files);
});

但是,每当我上传图片时,它都不会出现在/ public / images中。我的代码出了什么问题?非常感谢!

您的html表单标记中缺少

enctype="multipart/form-data"。如果没有它,它会将您的表单发布为application / x-www-form-urlencoded,它不包含任何文件数据。
