Debugging

Developers can use a test server for file uploading. For that they should add a parameter debug to the server url. The url would be 'https://services.krediidiinfo.ee/soap.php?name=KiDocExchange&debug'.

Example in PHP

<?php
/**

 */
$wsdl_url = 'http://services.krediidiinfo.ee/KiDocExchange.wsdl';
$params = array('location'      => 'https://services.krediidiinfo.ee/soap.php?name=KiDocExchange&debug'
              , 'login'       => 'username' // <-- username. Make sure username is string type (PHP bug?).
              , 'password'    => 'password'   // <-- password
	        );
    	
$client = new SoapClient($wsdl_url, $params);

// Uploading file.
$content = 'I am a little test file!';
$docID = $client->startUpload('test.txt');
$client->uploadChunk($docID, $content);		

$md5 = md5($content);
$result = $client->finishUpload($docID, $md5);
if ($result != 0) {
    die("upload failed.! Error code: {$result}\n");
}

// Downloading file
$start = 0;
$count = 512; // can be a big number if you do not have to display download progress.
$data = '';
while ($chunk = $client->downloadChunk($docID, $start, $count)) {
    $start += $count;
    $data .= $chunk;
}

if ($content != $data) {
    echo "Something is not right!\n";
} else {
    echo "We got back: {$data}\n";
}
