I am uploading PDF's to AmazonS3 manually, using Panic Transmis and via a PHP script/API.
For some reason, some display in your browser, and some force download.
I have checked permission and can not seem to see any issues, Can anyone help explain how to make PDF's always display in browser ( unless the user specifies otherwise ).
I don't think it is as browser issue.
You need to change the Content-Type and Content-Disposition.
Content-Type: application/pdf;
Content-Disposition: inline;
Using the AWS S3 console, find the file and using the context menu (right click) select Properties then it's under Metadata.
Or change this programmatically:
http://docs.aws.amazon.com/AWSSDKforPHP/latest/index.html#m=AmazonS3/create_object
In companion with well's answer, here an example:
public function save($bucket, $name, $content, $options = [])
{
$this->s3->putObject([
'Bucket' => $bucket,
'Key' => $name,
'Body' => $content,
] + $options);
}
$this->bucket->save('my-bucket', 'SofiaLoren.pdf', $content, [
'ContentType' => 'application/pdf',
'ContentDisposition' => 'inline',
]);

I'm trying to upload a file with presigned AWS url.
I generate a presigned url like that :
use AsyncAws\S3\S3Client;
$s3 = new S3Client();
$bucket = 'my-bucket';
$key = 'myfile.pdf';
$date = new \DateTimeImmutable('+15minutes');
$contentType = 'application/pdf';
$input = new GetObjectRequest([
'Bucket' => $bucket,
'Key' => $key,
'ContentType' => $contentType
]);
$presignUrl = $s3->presign($input, $date);
This code above works fine, I get a presigned url like this : "https://my-bucket.s3.eu-west-3.amazonaws.com/myfile.pdf?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20220809T141153Z&X-Amz-Expires=900&X-Amz-Credential=XXXXXXXXXXXXXXX%2F20220809%2Feu-west-3%2Fs3%2Faws4_request&x-amz-content-sha256=UNSIGNED-PAYLOAD&X-Amz-SignedHeaders=host&X-Amz-Signature=XXXXXXXXXXXXXXXXXXXXXXXXXX"
Next, I try to use this url to upload a file with Postman.
I select my pdf file via Body / binary / Select file
This is my postman config and response :
As you can see, I have a 403 code response.
These are my headers (of course I've tried with differents Content-Type but nothing better than the exactly same 403 response.
Important information : With the same $s3 instance and authentification, if I try to get object url ($content = $s3->getObject($input); with AsyncAws), it works well. So I suppose, it is not an authentification issue.
Thanks in advance if you have any idea for me !
Summary:
I tried to obtain AWS Cognito User name (OAuth2 from Google) with Perl module Paws::CognitoIdp::GetUser but I failed the code:
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
with the error Invalid Access Token.
Environment
I am developing Web service with following environment:
AWS + EC2 + Ubuntu 20.04 + nginx 1.20.1 + Perl 5.30.0
Using Cognito with Google OAuth2.0
What I can do now
When you access my Web service, Sign In with Google button will appear. If you click it, you can run my Perl CGI script.
What I cannot do now
I want to obtain your Google user name and mail address, but I cannot.
What I did
I wrote the following code:
my $cognito_idp = Paws->service('CognitoIdp',
region => "ap-northeast-1",
max_attempts => 3,
);
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
my $uname = $GetUserResponse->Username;
Then...
When I access my Web service, it failed with the Software error:
Software error:

For help, please send mail to this site's webmaster, giving this error message and the time and date of the error.
Maybe...
I referred following to the documentation
Maybe 'MyTokenModelType' is just the placeholder and I should specify the correct code.
But I don't know how I can make it.
In addition, I want to know how can I obtain not only user name but also user email address.
(Additional Info 2021-11-12)
Thanks to the comment, I read the article:
How to generate access token for an AWS Cognito user?
and I hacked AWS CLI command but I have not got the answer yet.
I think I got to do $ aws connito-idp initiate-auth but I cannot find what arguments I should pass.
In the AWS => Cognito => Users and groups menu, I see the entry of a user of my Web app.
Username: google_??????????
Enabled: Enabled
Account status: EXTERNAL_PROVIDER
Email: (users_email)
I changed my code like this for the experiment to find what information my Web app has.
use Data::Dumper;
my $cognito_idp = Paws->service('CognitoIdp',
region => "ap-northeast-1",
max_attempts => 3,
);
# my $GetUserResponse = $cognito_idp->GetUser(
# AccessToken => 'MyTokenModelType',
# );
# my $uname = $GetUserResponse->Username;
print "Content-type: text/html\n\n\n";
print '<!DOCTYPE html>';
print '<html><pre>';
print Dumper $cognito_idp;
print '</pre></html>';
and I see the contents of $cognito_idp like this:
$VAR1 = bless( {
'_region_for_signature' => 'ap-northeast-1',
...
'credentials' => bless( {
...
'selected_provider' => bless( {
'expiration' => 1636712506,
'actual_creds' => {
'Type' => 'AWS-HMAC',
'SecretAccessKey' => '??????????????',
'Code' => 'Success',
'AccessKeyId' => '???????????????',
'LastUpdated' => '2021-11-12T03:54:16Z',
'Token' => '?????????????????????????????????????',
'Expiration' => '2021-11-12T10:21:46Z'
},
...
I hope I could get the information of the user from the data above.
My question is, how I can specify the MyTokenModelType value of the code:
my $GetUserResponse = $cognito_idp->GetUser(
AccessToken => 'MyTokenModelType',
);
Still I want your info.
Thanks again.
I try to get from PHP the information about the currently connected clients.
http://10.0.0.2:8000/admin/listclients?mount=/stream.mpeg
but this required an authenfication, which is not possible from a program. So I tried
http://10.0.0.2:8000/admin/listclients?mount=/stream.mpeg&user=xyz&pass=wert
but Icecast does not accept the user and pass. If I do it inside a browser it works?
In which way I have to provide user and pass?
Or is some additional information required?
Google did not help me.
It's not possible to put user and pass directlyin the URL. These information has to be base64 encoded and put into the header. Below you find a php example:
$url = "http://www.domain.eu:80004/admin/listclients?mount=/stream.mpeg";
$user = "source";
$pass= "password";
$opts = array('http' =>
array(
'method' => 'GET',
'header' => array ('Authorization: Basic '.base64_encode("$user:$pass"))
)
);
$context = stream_context_create($opts);
$list1 = file_get_contents($url1, false, $context);
You can use the admin password or the source password. I the example I have used the source password.
what path is actually in source?:
$photo = $facebook->api("/me/photos", "POST", array(
source => "#" . "YOUR_IMAGE_PATH",
message => "YOUR_MESSAGE"
));
Image path from the server (should I upload image first to my server?) or $_FILES['photo']['tmp_name']?
I just get CurlExceptionfailed creating formpost data
Where can I get image path?
Thanks
I'm trying to add a tab to a fanpage using the graph api/PHP SDK and I'm receiving an error :
(#210) Subject must be a page I've tried using both the user access_token AND the page access_token but neither work. I've tried using the page id of numerous accounts and still no go. Here is my code:
<?php
$path="/PAGE_ID/tabs/";
$access_token="ACCESS_TOKEN";
$params = array(
'app_id' => "APP_ID",
'access_token' => $access_token
);
try{
$install = $facebook->api($path, "POST", $params);
}catch (FacebookApiException $o){
print_r($o);
}
?>
And here is the error I get:
FacebookApiException Object
(
[result:protected] => Array
(
[error] => Array
(
[message] => (#210) Subject must be a page.
[type] => OAuthException
)
)
[message:protected] => (#210) Subject must be a page.
[string:Exception:private] =>
[code:protected] => 0
Thanks for any help you can provide!
If you are not limited to using the API to add your application to your page then you can follow the instructions provided by Facebook at this link :
https://developers.facebook.com/docs/reference/dialogs/add_to_page/
Essentially you can use a dialog ( see the link above ) or this direct URL to add tab apps to your page :
https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&display=popup&next=YOUR_URL
Dont forget to substitute APP_ID for your app id and next for a different URL
API Call is atm bugged: https://developers.connect.facebook.com/bugs/149252845187252?browse=search_4f31da351c4870e34879109
But here is a solution for JS: OAuthException "(#210) Subject must be a page." - just do not use the library and do your own call.
I did it with PHP:
<?php
$url = 'https://graph.facebook.com/<PAGE ID>/tabs?app_id=<APP ID>&method=POST&access_token=<PAGE ACCESS TOKEN>&callback=test';
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
?>
Echo value should be something like "test(true)".
