SimplePie错误- Wordpress上的卷曲超时

Question

我在我的Wordpress插件中使用fetch_feed()方法得到了error WP HTTP Error: cURL error 28: Operation timed out after 1001 milliseconds with 0 bytes received。

这是为了尝试获取更大的RSS提要，我需要增加Curl超时。不确定为什么设置为1秒而不是5秒？

关于这一点的WP文档不是非常详细的WP_Feed_Cache，特别是没有SimplePie_Cache类文档。

如果有任何帮助，我将不胜感激，因为我不确定是否能够连接到SimplePie来增加卷曲超时。另外，我尝试重写我自己的fetch_feed()方法，但没有成功：

    public function fetchFeed( $url ) {
    if( ! class_exists('\SimplePie', false) ) {
        require_once( ABSPATH . WPINC . '/class-simplepie.php' );
    }

    require_once( ABSPATH . WPINC . '/class-wp-feed-cache.php' );
    require_once( ABSPATH . WPINC . '/class-wp-feed-cache-transient.php' );
    require_once( ABSPATH . WPINC . '/class-wp-simplepie-file.php' );
    require_once( ABSPATH . WPINC . '/class-wp-simplepie-sanitize-kses.php' );

    $feed = new \SimplePie();

    $feed->set_sanitize_class( 'WP_SimplePie_Sanitize_KSES' );
    // We must manually overwrite $feed->sanitize because SimplePie's
    // constructor sets it before we have a chance to set the sanitization class
    $feed->sanitize = new \WP_SimplePie_Sanitize_KSES();


    /* Customize sanitization */
    $feed->sanitize->enable_cache = false;
    $feed->sanitize->timeout = 60;
    $feed->sanitize->useragent = "Custom Testing Feed Reader";

    $feed->set_cache_class( 'WP_Feed_Cache' );
    $feed->set_file_class( 'WP_SimplePie_File' );

    $feed->set_feed_url( $url );
    $feed->set_timeout( 30 );
    /** This filter is documented in wp-includes/class-wp-feed-cache-transient.php */
    $feed->set_cache_duration( apply_filters( 'wp_feed_cache_transient_lifetime', 60, $url ) ); //changing cache time to 60 seconds (instead of 12 hours)
    /**
     * Fires just before processing the SimplePie feed object.
     *
     * @since 3.0.0
     *
     * @param object $feed SimplePie feed object (passed by reference).
     * @param mixed  $url  URL of feed to retrieve. If an array of URLs, the feeds are merged.
     */
    do_action_ref_array( 'wp_feed_options', array( &$feed, $url ) );
    $feed->init();
    // $feed->set_output_encoding( get_option( 'blog_charset' ) );
    $feed->set_output_encoding( "UTF-8" ); //set statically to UTF-8

    if ( $feed->error() )
        return new \WP_Error( 'simplepie-error', $feed->error() );

    return $feed;
}

我可以通过使用以下代码来增加Curl超时：

//Set HTTP Request Timeout
add_filter('http_request_args', 'my_http_request_args', 100, 1);
function my_http_request_args( $r ) {
    $r['timeout'] = 30;
    return $r;
}

//Setting WP HTTP API Timeout
add_action('http_api_curl', 'my_http_api_curl', 100, 1);
function my_http_api_curl( $handle ) {
    curl_setopt( $handle, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt( $handle, CURLOPT_TIMEOUT, 30 );
}

// Setting custom timeout for the HTTP request
add_filter('http_request_timeout', 'my_custom_http_request_timeout', 101 );
function my_custom_http_request_timeout( $timeLimit ) {
    return 30;
}
