titanium appcelerator php mcrypt_问答_开发者_运维开发者技术经验分享

i have tried lots of stuff, and im still having trouble... im working w/ titanium appcelerator studio (newest version) on a pc (win7) creating desktop apps with php. all my other tests have been going great so far, but i have run into trouble using the mcrypt functions.

here's the code im working with:

<html>
<head>
<title> crypto </title>
<style type="text/css">
*, html, body {
    margin: 0;
    padding: 0;
    border: 0;      
}
body {
    background: #000;
    color: #fff;
    font: normal 12pt Arial, Helvetica, San-serif;
}
.wrap {
    margin: 20px auto;
    width: 80%;
    border: 1px solid #ccc;
    background: #333;
}
.row {
    padding: 5px;
    border-bottom: 1px solid #666;
}
</style>
<script type="text/php">

function check($name) {
    $d = '<div class="row">';
    $e = '</div>';
    if(function_exists($name)) {
        return $d.$name.": found".$e;
    } else {
        return $d.$name.": not found".$e;
    }
}
function test1() {
    $key = "this is a secret key";
    $input = "Let us meet at 9 o'clock at the secret place.";
    $encrypted_data = mcrypt_cbc('tripledes', $key, $input, 'mcrypt_encrypt');    

    $d = '<div class="row">';
    $b = '<br/>';
    $e = '</div>';
    return $d."key:".$b.$key.$e.$d."clear     text:".$b.$input.$e.$d."encrypted:".$b.$encrypted_data.$e;
}
function test2() {
    $key = "this is a secret key";
    $input = "Let us meet at 9 o'clock at the secret place.";

    $td = mcrypt_module_open('tripledes', '', 'cbc', '');
    $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), 'mcrypt_rand');//alt_mcrypt_create_iv(8));
    mcrypt_generic_init($td, $key, $iv);
    $encrypted_data = mcrypt_generic($td, $input);
    mcrypt_generic_deinit($td);
    mcrypt_module_close($td);
    $d = '<div class="row">';
    $b = '<br/>';
    $e = '</div>';
    return $d."key:".$b.$key.$e.$d."clear     text:".$b.$input.$e.$d."encrypted:".$b.$encrypted_data.$e;
}
function alt_mcrypt_create_iv($size) {
    $iv = '';
    for($i = 0; $i < $size; $i++) {
        $iv .= chr(rand(0,255));
    }
    return $iv;
}
</script>

    function ready() {
        $("#box").html(check("md5"));
        $("#box").append(check("sha1"));
        $("#box").append(check("xero")); // a fake function name for testing
        $("#box").append(check("mcrypt_encrypt"));

<div id="box" class="wrap">

</html>

basically there are 3 div, then you press the 'test' button a series of tests are run. first i call function_exists lots of times to see if the mcrypt functions are available (the are showing up correctly). then i execute test1 and test2 functions, each of which try and do a simple string encryption and return the results. one uses the old method mcrypt_cbc and the other the newer one mcrypt_generic.

when i run the app, everything seems to execute ok, e.g. im not seeing any error in the debugger (though php开发者_开发知识库 error handling is a bit weird in Ti). but when i return the $encrypted_data variable from ether function nothing is returned. if i remove it from the return statement, i get all the other variables, but not the part i want.

any other Ti users have any suggestions for me?

thanx in advance.
