php cutycapt 权限,CutyCapt与php exec

我设法让CutyCapt在最后使用php成功运行. $_parameters通过AJAX传递给php脚本.希望这可以帮助…

case 'Output_Chart': {

// We always create the .png. We use the ImageMagick convert (IMC) command to make .pdfs

if ($_Suffix == 'pdf') {

$IMC = ";convert -page 735x850 '$_PathOut/$_ChartName.png' '$_PathOut/$_ChartName.pdf'";

} else {

$IMC = '';

}

// Prepare the query string for the CutyCapt URL

$sQuery_Pattern = '?Path=%s&iDL=%d';

$sQuery = sprintf($sQuery_Pattern, $_Path, $_iDL);

// Prepare CutyCapt's command and parameters (NB: query string and out parameter are enclosed in aposts for the shell)

$sCC_Cmd = '/var/www/LF/Includes/CutyCapt';

$sCC_URL = "http://localhost/LF/LFPrint.html'$sQuery'"; // Note: Inner apostrophes

$sCC_Out = "'$_PathOut/$_ChartName.png'";

$sCC_Pattern = ' --url=%s --out=%s --delay=%d --min-width=%d';

$sCC_Options = sprintf($sCC_Pattern, $sCC_URL, $sCC_Out, $_Delay, $_MinWidth);

//$sCC_CmdLine = $sCC_Cmd . $sCC_Options . " 2> CutyCapt.err.txt";

$sCC_CmdLine = $sCC_Cmd . $sCC_Options . " 2> /dev/null";

// Prepare the final command line with xvfb-run, CutyCapt, and the URL?QueryString

$sCC_CmdLine = 'xvfb-run --auto-servernum --server-args="-screen 0, 800x1000x24" ' . $sCC_CmdLine . $IMC;

exec( $sCC_CmdLine, $aOutput = array(), $ret);

// Wait for and then return the results. sCC_CmdLine and aOutput are just for debugging

echo json_encode(array("ret" => $ret, "cmd" => $sCC_CmdLine, "Output" => $aOutput));

break;
