PEAR::XML_RPCで更新通知pingのRESTサーバに送信してみた

PEARのXML_RPCを使って、RESTサーバに送信した場合どうなるか見てみた。

<?php
 
require_once "XML/RPC.php";
 
$title  = "KoshigoeBLOG";
$url    = "http://blog.koshigoe.jp/";
$rss    = "http://blog.koshigoe.jp/index.xml";
 
$params = array(
                new XML_RPC_Value("", "string"),
                new XML_RPC_Value("", "string"),
                );
$message = new XML_RPC_Message("weblogUpdates.ping", $params);
 
$clients = array();
 
$server    = "blogsearch.google.co.jp";
$endpoint  = "http://blogsearch.google.co.jp/ping?name=" . urlencode($title) .
    "&url=" . urlencode($url) . "&changeURL=" . urlencode($rss);
$cli       = new XML_RPC_Client($endpoint, $server);
$cli->setDebug(1);
$clients[] = $cli;
 
$server    = "api.my.yahoo.co.jp";
$endpoint  = "http://api.my.yahoo.co.jp/rss/ping?u=" . urlencode($rss);
$cli       = new XML_RPC_Client($endpoint, $server);
$cli->setDebug(1);
$clients[] = $cli;
 
foreach ($clients as $cli) {
    $resp = $cli->send($message);
    if (!$resp) {
        echo 'Communication error: ' . $cli->errstr;
        exit;
    }
    if (!$resp->faultCode()) {
        $val = $resp->value();
        $data = XML_RPC_decode($val);
        echo $data[0]['name'] . ' is at version ' . $data[0]['version'];
    } else {
        echo 'Fault Code: ' . $resp->faultCode() . "\n";
        echo 'Fault Reason: ' . $resp->faultString() . "\n";
    }
}

プログラムを正常終了出来て、pingサーバからのHTTPレスポンスもping受信完了のもの。ただ、RESTサーバからのレスポンスはtest/plainなので、XML-RPCのレスポンス処理で問題が起きる。といっても、HTTPステータスを確認して問題なかった後のXMLパーズでの問題。
