未返回Luracast Restler多格式XML

Question

i have a question regarding Luracast Restler v2.

I have created my index.php with the following content:

require_once 'framework/restler.php';

spl_autoload_register('spl_autoload');

$r = new Restler();
$r->setSupportedFormats('JsonFormat', 'XmlFormat');
$r->addAPIClass('PROCESSOR');
$r->handle();

Now i have my processor.php with the following code sample - this is just a small part of the codebase ! :

class PROCESSOR {
    private $api_ver    = '0.1';
    private $allowed    = array('xxx.xxx.xxx.xxx');

    public function index( $request_data ) {
        if(empty($request_data)) throw new RestException(400,"parameter missing");
        $this->checkHost();
        $this->get_vars = $request_data;

    $result = new stdClass();               
    $result->version    = $this->api_ver;
        $result->timestamp  = date(DATE_RFC822);
        $result->generated  = $totaltime.' sec.';
        $result->type       = 'success';
        $result->filesize   = $this->res_filesize;
        $result->url        = $this->res_saved; 

        return $result;     
    }
}

My Problem is now, that when i send the request to http://api.myserver.xx/processor/?url=http://www.test.fr

The API does what it has to do and returns JSON string.

But when i type http://api.myserver.xx/processor .xml /?url=http://www.test.fr it also returns JSON - and not XML?!?

What's wrong here?

Thanks.

与JsonFormat不同， XmlFormat不包含在restler.php它存在于xmlformat.php确保已将其复制到与restler.php相同的文件夹中；如果仍无法正常工作，请尝试手动包含该类。

I found this post while dealing with the same issue. I have located an issue with the code, at least with the GitHub code retrieved on 13 Feb 2012. In the restler.php class function getResponseFormat() , starting at line 503, the extensions are pulled from the request url.

The first line in the while loop (512) extracts the ".xml" extension just fine, but the following lines manipulate the variable so when the conditional statement evaluates $extension , it is no longer the expected value. I simply added a variable after the first line in the while loop to hold the original value of extension, then check if that value exists in the $format_map . The example project works as expected once doing this.

FYI, I do not think this is a platform dependent issue, but if so, here is my environment:

OS: Mac OSX 10.7.3
PHP: v5.3.6
Apache: 2.2.21

Hope this helps.

In addition to Rhoderunner: I think the more precise bug is in line 514 of the restler.php file. This line has to be:

$extension = array_shift($extension);

and NOT :

$extension = array_shift($extensions);

So we have to get rid of the s .
