節點js s3fs圖像上傳到aws amazon s3服務器並設置ContentType

Question

以下是我的節點JavaScript代碼，用於使用s3fs庫將圖像上傳到Amazon S3。圖像正確上傳，但是當我嘗試在瀏覽器中查看該圖像時，它提供了下面提到的錯誤。

我檢查了內容類型，默認保存爲octet-stream。如果我手動將其設置爲image/jpeg，那麼該圖像可在瀏覽器中查看。任何人都可以告訴我只能在上傳完成後才能設置Content-Type嗎？

我試圖設置內容類型，但它不工作S3fs圖像上傳。

錯誤代碼： -

<Error> 
<Code>NoSuchKey</Code> 
<Message>The specified key does not exist.</Message> 
</Error> 

我的實際代碼： -

var AWS= require('aws-sdk'); 

    var fs = require('fs'); 

    var S3FS = require('s3fs'); 

    var s3fsImpl = new S3FS('bbqmobileimages/images/banners',{ 
     accessKeyId:'A********A', 
     secretAccessKey:'****************' 
    }); 

    var multiparty = require('connect-multiparty'), 
     multipartyMiddleware = multiparty(); 

    router.use(multipartyMiddleware); 

     router.post('/api/v1/backoffice/upload/image',function(req,res){ 

      console.log(JSON.stringify(req.files)); 
      var file = req.files; 
      console.log("file",JSON.stringify(file)) 
      console.log("original name:- "+file.fileUpload.originalFilename); 
      console.log("Path:- ",file.fileUpload.path); 
      var stream = fs.createReadStream(file.fileUpload.path); 
      return s3fsImpl.writeFile(file.fileUpload.originalFilename, stream).then(function(){ 
       fs.unlink(file.fileUpload.path, function(err){ 
        console.error(err); 
       }) 
       console.log("Sucessfully uploaded to Amazon S3 server"); 
      }); 
     });

嘗試

s3fsImpl.writeFile(file.fileUpload.originalFilename, stream, {"ContentType":"image/jpg"})
