我正在尝试配置 SimplePie RSS 解析器以将提要缓存到 mySQL 数据库中，但当我尝试加载 SimplePie 页面时，我不断收到此错误消息:

  • fatal error :在非对象上调用成员函数 set_cache_location()
  • 警告:substr() 期望参数 1 为字符串，数组中给出
  • 警告:PDO::__construct() 期望参数 2 为字符串，给定数组

当我将“port”设置为“port”时，我收到以下错误消息:

Warning: mysql:// "IT DISPLAYS MY DB USERNAME AND PASSWORD HERE" is not writeable. Make sure you've set the correct relative or absolute path, and that the location is server-writable. in /home/...../SimplePie.php on line 1357

有人熟悉SimplePie吗？

编辑

在下面的代码中，我显然遗漏了 mySQL 设置的用户名和密码。但我只是想承认我“知道”我应该替换这些值(value)观。另外，我使用“3306”作为端口号，因为我被告知这是 mysql 的默认端口号...以及“localhost”作为主机名

$feed->set_cache_location('mysql://用户名:密码@localhost:3306/database');

<?php

include('./base.php');
require_once('./php/autoloader.php');

$feed = new SimplePie();
$feed->set_cache_location('mysql://username:password@hostname:3306/database');

$rssurl = $_GET['r'];
$feedlimit = $_GET['limit'];

if (!empty($feedlimit)) {
$feedlimit = $_GET['limit'];
}

else {

$feedlimit = 10;

}

// Set which feed to process.
if (!empty($rssurl)) {

    $feed->set_feed_url($rssurl);

}

else 

    $rss_results = mysql_query("SELECT feed_id, feed_url, feed_title, feed_order, feed_page_id FROM user_feeds  WHERE ((feed_owner = '" . $_SESSION['UserId'] . "') AND (feed_page_id = '" . $pageid . "')) ORDER BY feed_order ASC LIMIT 1;");

        if ($rss_results) {

        while($row = mysql_fetch_array($rss_results))
        {
        $feed->set_feed_url($row[feed_url]);

        }

        }
        else {
          // something went wrong.
          echo mysql_error();
}



$feed->enable_cache(true);

// Run SimplePie.
$feed->init();

// This makes sure that the content is sent to the browser as text/html and the UTF-8 character set (since we didn't change it).
$feed->handle_content_type();

// Let's begin our XHTML webpage code.  The DOCTYPE is supposed to be the very first thing, so we'll keep it on the same line as the closing-PHP tag.

最佳答案

我检查了php代码，发现问题出在MySQL.php中。

作为一个快速修复，只需注释掉 Cache 目录中的 MySQL.php(第 90-94 行):

public function __construct($location, $name, $type)
{
    $this->options = array(
          //'user' => null,
          //'pass' => null,
          //'host' => '127.0.0.1',
          //'port' => '3306',
          //'path' => '',
          'extras' => array(
                'prefix' => '',
          ),
    );
    $this->options = array_merge_recursive($this->options, SimplePie_Cache::parse_URL($location));

然后它应该可以工作。
