Question

Aşağıdaki kod var: Ben neysem hiçbir fikrim yok

<Code>AccessDenied</Code><Message>Invalid according to Policy: Policy Condition failed: ["starts-with", "$Filename", ""]</Message>

: Bu istek aşağıdaki hatayı alıyorum geçer zaman

var fd = new FormData(); 

     var key = "events/" + (new Date).getTime() + '-'; 

     fd.append('key', key); 
     fd.append('acl', Acl); 
     fd.append('Content-Type', "image/jpeg"); 
     fd.append('AWSAccessKeyId', AWSAccessKeyId); 
     fd.append('policy', Policy); 
     fd.append('name', "Policy13492345"); 
     fd.append('success_action_status', "201"); 
     fd.append('signature', Signature);   
     fd.append("file", blob); 
     fd.append("filename", fileName + ".jpg"); 
     var xhr = new XMLHttpRequest(); 



     xhr.upload.addEventListener("progress", uploadProgress, false); 
     xhr.addEventListener("load", uploadComplete, false); 
     xhr.addEventListener("error", uploadFailed, false); 
     xhr.addEventListener("abort", uploadCanceled, false); 

     xhr.open('POST', 'https://s3.amazonaws.com/' + Bucket + '/', true); 

     xhr.send(fd); 

yanlış yaptığımda, blobumu şu şekilde oluşturur:
