密码站点上的PHP curl multi

密码站点上的PHP curl multi,php,curl,curl-multi,Php,Curl,Curl Multi,我目前正在使用以下(旧)代码登录网站 public function login() { $url1 = 'https://...'; /* Initial page load to collect initial session cookie data */ $url2 = 'https://...'; /* The page to POST login data to */ $url3 = 'https://...'; /* The page redirecte

我目前正在使用以下(旧)代码登录网站

public function login() {
    $url1 = 'https://...';  /* Initial page load to collect initial session cookie data */
    $url2 = 'https://...';  /* The page to POST login data to */
    $url3 = 'https://...';  /* The page redirected to to test for success */
    $un = 'user';
    $pw = 'pass';

    $post_data = array(
        'authmethod' => 'on',
        'username'   => $un,
        'password'   => $pw,
        'hrpwd'      => $pw
    );

    $curlOpt1 = array(
        CURLOPT_URL            => $url1,
        CURLOPT_COOKIEJAR      => self::COOKIEFILE,
        CURLOPT_COOKIEFILE     => self::COOKIEFILE,
        CURLOPT_FOLLOWLOCATION => TRUE,
        CURLOPT_HEADER         => FALSE,
        CURLOPT_RETURNTRANSFER => TRUE,
        CURLOPT_SSL_VERIFYPEER => FALSE
    );

    $curlOpt2 = array(
        CURLOPT_URL            => $url2,
        CURLOPT_COOKIEJAR      => self::COOKIEFILE,
        CURLOPT_COOKIEFILE     => self::COOKIEFILE,
        CURLOPT_FOLLOWLOCATION => TRUE,
        CURLOPT_POST           => TRUE,
        CURLOPT_POSTFIELDS     => http_build_query($post_data)
    );

    $this->ch = curl_init();
    if ( !$this->ch ) {
        throw new Exception('Unable to init curl. ' . curl_error($curl));
    }

    /* Load the login page once to get the session ID cookies */
    curl_setopt_array( $this->ch, $curlOpt1 );
    if ( !curl_exec( $this->ch ) ) {            
        throw new Exception( 'Unable to retrieve initial auth cookie.' );
    }

    /* POST the login data to the login page */
    curl_setopt_array($this->ch, $curlOpt2);
    if ( !curl_exec( $this->ch ) ) {
        throw new Exception( 'Unable to post login data.' );
    }

    /* Verify the login by checking the redirected url. */
    $header  = curl_getinfo( $this->ch );
    $retUrl = $header['url'];

    if ( $retUrl == $url3 ) {
        /* Reload the login page to get the auth cookies */
        curl_setopt_array( $this->ch, $curlOpt1 );
        if ( curl_exec( $this->ch ) ) {
            return true;
        } else {
            throw new Exception( 'Unable to retrieve final auth cookie.' );
        }
    } else {
        throw new Exception( 'Login validation failure.' );
    }

    return false;
}
然后我用

public function getHtml($url) {
    $html = FALSE;

    try {
        curl_setopt($this->ch, CURLOPT_URL, $url);
        $page = curl_exec($this->ch);
    } catch (Exception $e) {
        ...
    }

    /* Remove all tabs and newlines from the HTML */
    $rmv = array("\n","\t");
    $html = str_replace($rmv, '', $page);

    return $html;
}
…对于每个页面请求。我的问题是,如何将其转换为使用curl\u multi\u exec来加快数百次查找?我找不到任何使用curl\u multi登录的示例。我是否简单地用curl\u multi\u exec替换所有curl\u exec? 此外,如果你看到任何其他明显的错误,评论当然是受欢迎的


说清楚一点,我想用一个用户/通行证登录,然后将这些凭证用于多个页面请求。

已经有一段时间了,但我想发布我的最终解决方案。我发现了一个很棒的多重卷曲库,这很有帮助。基本上,在收集了登录cookie(如我的原始问题所示)之后,我将其和其他选项反馈到每个多请求的rolling curl实例中,然后执行批处理。工作起来很有魅力

public function getMultiPage(array $urls, $url_prepend=NULL, $callback) {
    $rc = new RollingCurl(array('Att_Screen_Scraper', $callback));
    $rc->window_size = 15;   /* number of threads to run */
    $rc->options = array(
        CURLOPT_COOKIEJAR      => self::COOKIEFILE,
        CURLOPT_COOKIEFILE     => self::COOKIEFILE,
        CURLOPT_FOLLOWLOCATION => TRUE,
        CURLOPT_HEADER         => FALSE,
        CURLOPT_RETURNTRANSFER => TRUE,
        CURLOPT_SSL_VERIFYPEER => FALSE
    );

    foreach ($urls as $i=>$url) {
        $request = new RollingCurlRequest($url_prepend . $url);
        echo $url_prepend . $url . "<br>\n";
        $rc->add($request);
    }

    if(!$rc->execute()) {
        throw new Exception('RollingCurl execute failed');
    }

    return TRUE;
}
公共函数getMultiPage(数组$url,$url\u prepend=NULL,$callback){
$rc=新的RollingCurl(数组('Att_Screen_Scraper',$callback));
$rc->window_size=15;/*要运行的线程数*/
$rc->options=array(
CURLOPT_COOKIEJAR=>self::COOKIEFILE,
CURLOPT_COOKIEFILE=>self::COOKIEFILE,
CURLOPT_FOLLOWLOCATION=>TRUE,
CURLOPT_头=>FALSE,
CURLOPT_RETURNTRANSFER=>TRUE,
CURLOPT_SSL_VERIFYPEER=>FALSE
);
foreach($i=>$url的url){
$request=newrollingcurlrequest($url\u prepend.$url);
回显$url\u前缀。$url。“
\n”; $rc->add($request); } 如果(!$rc->execute()){ 抛出新异常(“RollingCurl执行失败”); } 返回TRUE; }

请注意,此解决方案需要回调来处理每个请求的返回。RollingCurl的文档很好地描述了这一点,所以我在这里不再重复。

为什么这看起来很邪恶?别担心,PHP不会造成任何真正的损害。因为curl中的所有东西看起来都很邪恶?我们在工作中使用它从其他部门收集产品数据,而不直接访问数据库。我同意这毫无意义,但这正是他们想要的。我们必须查找数百条记录,不想手动填写每一条记录的web表单。@isius,这很有意义,如果需要,数据库可以更改,“web服务”可以保持不变
