将复杂的哈希存储在Apache :: Sessions：MySQL会话中

Question

So, I'm trying to store a decoded JSON object into a tied apache session. This is my code:

    $url="https://apilink";

    $content = get($url);
    die "Can't Get $url" if (! defined $content);

    $jsonOb = decode_json($content);
    %aprecords = %$jsonOb;

    #Push the jsonOb in the session
    $session{apirecords} = \%aprecords ;

$session{apirecords} does not store the %aprecords reference. Although, when I substitute the statement to $session{apirecords} = \\%jsonOb ; , it stores apirecords in the sessions table but the reference to %jsonOb has no values in it.

PS: I have tried the following and none of them seem to work: 1) $session{apirecords} = \\%$jsonOb ; 2) $session{apirecords} = { %aprecords } ;

JSON object is perfectly well structured.

Code for tying a session:

  tie %session, "Apache::Session::MySQL", $sessionID, 
   {
    Handle => $dbObject,
    LockHandle => $dbObject,
    TableName => 'sessions',
    };

  #If a session ID doesn't exist, create a new session and get new session ID
  if (!defined ($sessionID)){
     $sessionID = $session{_session_id};
     $session{count}=0;
}

A helping hand would be much much appreciated!

Answer 1

As pointed out by GMB. The blob size(64 KB) wasn't big enough for the JSON object. The solution is to change blob datatype to mediumblob .
