AWS Pre signed URL
I'm Trying to upload image/Video Using PHP / Javascript to AWS S3
this is My PHP Code
<?php
use AwsS3ExceptionS3Exception;
$filename = isset($_GET['file']) ? $_GET['file'] : '';
$mime = isset($_GET['mime']) ? $_GET['mime'] : '';
function getSignedUrl($filename, $mime) {
require $_SERVER['DOCUMENT_ROOT'].'/ibrainmart/start.php';
$BUCKET = $config['S3']['bucket'];
$tmp_name = $filename;
try {
$command= $S3->getCommand('PutObject', array(
'Bucket' => $BUCKET,
'Key' => $tmp_name,
'ContentType' => $mime,
'Body' => ''
));
$signedUrl = $S3->createPresignedRequest($command, "1 week");
} catch (S3Exception $e) {
echo $e->getMessage() . "n";
}
echo $signedUrl->getUri();
return $signedUrl->getUri();
}
echo getSignedUrl($filename,$mime);
?>
This my Java Script Code
$(function(){
// run onLoad
$("#profilePic").uploadHandler("headerupload.php");
});
// Upload image to S3
$.fn.uploadHandler = function(s3presignedApiUri)
{
$(document).ready(function (e) {
$("#profilePic").on('change',(function(e) {
e.preventDefault();
console.log("ajax going to start..!");
var fileupload = $('input[name=file]');
var fileToUpload = fileupload[0].files[0];
if(fileToUpload !="undefined"){
var formData = new FormData();
formData.append("file", fileToUpload);
}
console.log("fileToUpload.name"+fileToUpload.name);
$.ajax({
url: s3presignedApiUri, // Url to which the request is send
type: "GET", // Type of request to be send, called as method
data: 'file='+ fileToUpload.name + '&mime=' + fileToUpload.type , // Data sent to server, a set of key/value pairs (i.e. form fields and values)
cache: false, // To unable request pages to be cached
})
.done(function(data) // A function to be called if request succeeds
{
console.log("data ............"+data);
$.ajax({
url : data.url,
type : "PUT",
data : fileToUpload,
cache : false,
contentType : fileToUpload.type,
processData : false
})
.done(function() {
console.info("s3-upload done: "); // REMOVE ME FOR PRODUCTION USE
})
.fail(function(e) {
console.error("s3-upload failed",e); // REMOVE ME FOR PRODUCTION USE
});
})
.fail(function(e)
{
console.log("file passing error.!");
})
}));
});
}
All these Functions Work Great i guess even after execute it gives me file Upload Successfully Message too.but when i check s3 nothing is there.
even in console it generate the Presignrd URL too like below.but when i try to Click it it gives me SignatureDoesNotMatch error.(Please Click the URL).what could be the Error..?

After trying days found this solution.
Use AWS Cognito Federate pools for generate session to AWS S3 and Upload files using temporary generated Secret key , accessID and Session.below i listed code sample for that.
getAuthenticateUser().getSession(function(err,session){
if (err) {
console.log("Error"+err);
return;
}
if(session.isValid())
{
const authenticator = 'cognito-idp.us-east-2.amazonaws.com/us-east-2_cfmOv3jSL';
AWS.config.region = 'us-east-2'; // Region
AWS.config.credentials = new AWS.CognitoIdentityCredentials({
IdentityPoolId: 'us-east-2:XXXXX-d2b7-XXXX-85c7-929aadf450b2',
Logins: {
[authenticator]: session.getIdToken().getJwtToken()
}
});
AWS.config.credentials.refresh((error) => {
if (error) {
console.error(error);
} else {
console.log('Successfully logged!');
}
});
AWS.config.getCredentials(function(err) {
if (err) console.log(err.stack); // credentials not loaded
else {
console.log("Access Key:", AWS.config.credentials.accessKeyId);
console.log("Access Key:", AWS.config.credentials.secretAccessKey);
console.log("Access Key:", AWS.config.credentials);
AWS.config.update({
AccessKeyId : AWS.config.credentials.AccessKeyId,
SecretAccessKey : AWS.config.credentials.SecretAccessKey ,
SessionToken : AWS.config.credentials.SessionToken
});
}
});
}
if(!session.isValid())
{
console.log("Session is not valid..!");
//Please Login to Continue
}
});
