Question

我正在尝试为Facebook群组构建一个抓取工具，而且我在运行此工具时获得了页面内容：

<?php
    $url = "https://www.facebook.com/groups/theGroupId/";

    $ch = curl_init($url);                              // initialize the CURL library in my PHP script so we can later work on it - inside the handler. 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     // curl_setopt() function is used to set options on the $ch handler.// in this case we use the CURLOPT_RETURNTRANSFER option
    $curl_scraped_page = curl_exec($ch);                //  "run all the stuff we've set" - return the data scraped to the variable $curl_scraped_page

    var_dump($curl_scraped_page);
    if ($curl_scraped_page === false) {
        die(curl_error($ch));
    }
    curl_close($ch);
    echo $curl_scraped_page;
?>

我收到此错误：“SSL证书问题：无法获取本地颁发者证书”。

我在本教程中运行：http://unitstep.net/blog/2009/05/05/using-curl-in-php-to-access-https-ssltls-protected-sites/解释了为什么会发生这种情况，以及如何通过两种不同的方式解决它，我尝试了两种方法但仍然得到相同的错误消息：

<?php
    $url = "https://www.facebook.com/groups/{theGroupId}/";

    $ch = curl_init($url);                              // initialize the CURL library in my PHP script so we can later work on it - inside the handler. 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     // curl_setopt() function is used to set options on the $ch handler.// in this case we use the CURLOPT_RETURNTRANSFER option
    //curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_CAINFO, getcwd() . "/CAcerts/GTECyberTrustGlobalRoot.crt");


    $curl_scraped_page = curl_exec($ch);                //  "run all the stuff we've set" - return the data scraped to the variable $curl_scraped_page

    var_dump($curl_scraped_page);
    if ($curl_scraped_page === false) {
        die(curl_error($ch));
    }


    curl_close($ch);



    echo $curl_scraped_page;
?>

这是确切的输出（使用var_dump）：

boolean false
SSL certificate problem: unable to get local issuer certificate

我做错了吗？这是否是正确的方法呢？

<?php

$url = "http://www.facebook.com/groups/4189052132/";
function curl($url) {
  $options = Array(
    CURLOPT_RETURNTRANSFER => TRUE,  
    CURLOPT_FOLLOWLOCATION => TRUE,  
    CURLOPT_AUTOREFERER => TRUE, 
    CURLOPT_CONNECTTIMEOUT => 120,   
    CURLOPT_TIMEOUT => 120,  
    CURLOPT_MAXREDIRS => 10, 
    CURLOPT_USERAGENT => "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1a2pre) Gecko/2008073000 Shredder/3.0a2pre ThunderBrowse/3.2.1.8", 
    CURLOPT_URL => $url, 
    CURLOPT_COOKIE => $session
);
    $ch = curl_init();  
    curl_setopt_array($ch, $options);   
    $data = curl_exec($ch); 
    curl_close($ch);    
    return $data;   
}   
$scraped_page = curl($url);
echo $scraped_page;
?>

无需验证其证书。这就是你遇到问题的原因。

如何在没有收到错误的情况下在facebook组上运行CURL：“SSL证书问题：无法获取本地颁发者证书”
