This's a bug ?

ErrorException in Upload.php line 131: rand() expects parameter 2 to be integer, float given

 $randNum = rand(1, 10000000000) . rand(1, 10000000000);

changed to `

    $randNum = rand(1, 100000000) . rand(1, 100000000);

`

建议改成下面样，兼容32位和64位 $randNum = rand(1, 2000000000) . rand(1, 2000000000);
