无法将图像上传到云中

你能告诉我，当我尝试上传图片到云中时，我做错了什么？

app.js我不需要在服务器上存储图像，所以我把它存储在内存中。 var cloudinary = require('cloudinary'); cloudinary.config({ cloud_name: 'hidden', api_key: 'hidden', api_secret: 'hidden' }); var multer = require('multer'); var storage = multer.memoryStorage() var upload = multer({ storage: storage })

网站表单（jade / pug） form(action="/?_csrf="+csrfToken method="post" enctype='multipart/form-data') input(type="file" name="avatar") input(type="submit" value="upload")

应用信息

  app.post('/', upload.single('avatar'), function(req, res, next){ console.log('Should be undefined:', req.file.path); //yes console.log('Should be the buffer:', req.file.buffer); //yes cloudinary.uploader.upload(req.file.path, function(result) { console.log(result) }); }); 

和我得到错误{ error: { message: 'Missing required parameter - file', http_code: 400 } }

 i find out how (just use Datauri): 

  var dUri = new Datauri(); dUri.format(path.extname('TEST').toString(), req.file.buffer); cloudinary.uploader.upload(dUri.content, function (err, result) { if (err) { console.log(err); } else { console.log(result); } });
