yahoocn邮箱登录脚本

最近发现线上登录Yahoo邮箱取地址薄的代码不能用了，调试发现是登录方式变换了，特通过HttpFox关注，重构代码如下：

define("USERAGENT","Mozilla/99.99 (compatible; MSIE 99.99; Windows XP 99.99)");
define("COOKIEJAR",tempnam("/tmp/cookie/","cookie"));
define("TIMEOUT",10);
define("REFER", "http://mail.cn.yahoo.com");
define("LOGIN_HOME", "http://mail.cn.yahoo.com");
define("LOGINURL", "https://edit.bjs.yahoo.com/config/login?"); 
........

 /**
     *get login parameters
     *@return @mixed
     *
     */
    public function getParam()
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, LOGIN_HOME);
        curl_setopt($ch, CURLOPT_USERAGENT,USERAGENT);
        curl_setopt($ch, CURLOPT_COOKIEJAR,COOKIEJAR);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $contents = curl_exec($ch);
        curl_close($ch);
		
	preg_match_all("/name=\".challenge\" value=\"(.*?)\"/", $contents, $arr_challenge);
	$challenge = $arr_challenge[1][0];
	preg_match_all("/name=.done value=\"(.*?)\"/", $contents, $arr_done);
	$done = $arr_done[1][0];
        return array('challenge'=>$challenge,
                      'done'=>$done);
    }
    
    /**

     */
    public function checkLogin($user,$password)
    {
        $params = $this->getParam();
        $done = $params['done'];
        $challenge = $params['challenge'];
	$postfields = ".intl=cn&.done={$done}&.src=ym&.cnrid=ymhp_&challenge=${challenge}&login={$user}&passwd={$password}&submit=";

        curl_setopt($ch, CURLOPT_POSTFIELDS,$postfields);

	$r = curl_exec($ch);
        curl_close($ch);

        if(strpos($r,"Caps Lock")) {
	    return False;
        } else {
	    return True;
