cakephp HttpResponseがクラス名かぶってる

概要

• cakephp 2.2でhttpSocket使ってスクレイピングしようとしたけど、戻り値のHttpResponseにあるべきプロパティやメソッドがない

参考

• cakephp2.0のHttpSocket
  • http://book.cakephp.org/2.0/en/core-utility-libraries/httpsocket.html
• 1系からの使い方の変更
  • http://weble.org/2011/10/31/oauth-consumer-class-a-support-to-2-0

サンプルコード

    public function index(){
        // disable view
        $this->autoRender = false;

        App::uses('HttpSocket', 'Network/Http');
        $http = new HttpSocket();
        $url = "http://cakephp.jp/";
        $response = $http->get( $url );
        if( ! $response ){
            return false;
        }

        echo $response->body();
    }

画面表示

Fatal error: Call to undefined method HttpResponse::body() in /home/atsushi-kambayashi/www/app/Controller/HogeController.php on line 29

メソッド一覧確認

下記コードでメソッド一覧確認

    public function index(){
        // disable view
        $this->autoRender = false;

        App::uses('HttpSocket', 'Network/Http');
        $http = new HttpSocket();
        $url = "http://cakephp.jp/";
        $response = $http->get( $url );
        if( ! $response ){
            return false;
        }

        echo "<pre>";
        var_dump( get_class_methods( $response ) );
        echo "</pre>";

        echo $response->body();
    }

出力はこんな感じ

  string(9) "setHeader"

cakephpのバグか

• 名前変えてくれと言う要望が出てる
  • http://cakephp.lighthouseapp.com/projects/42648/tickets/2765-rfc-rename-httpresponse-to-cakehttpresponse

クラス名変えて確認

$ ls -la lib/Cake/Network/Http/

HttpSocketに使用するレスポンスクラスの名称があるので変更

/**
 * Response classname
 *
 * @var string
 */
    public $responseClass = 'CakeHttpResponse'; // 元はHttpResponse

同ディレクトリにクラスコピーして内部のクラス名を変更

$ cp lib/Cake/Network/Http/HttpResponse.php lib/Cake/Network/Http/CakeHttpResponse.php 

/**
 * HTTP Response from HttpSocket.
 * 
 * @package       Cake.Network.Http
 */
class CakeHttpResponse implements ArrayAccess { 

メソッド名出力外して確認

とりあえずページ情報はとれた
