无法让推特小部件工作

Question

我想知道是否有人可以提供帮助？

我已经为客户购买了一个网络主题，但无法让 Twitter 小部件正常工作。这可能是非常简单的事情，但由于我不是Web开发人员，我正在努力找出阻止它工作的原因。

这是网页 http://www.blackrocksearch.co.uk/new/- Twitter 提要应显示在页脚中。它适用于模板演示站点，但我在项目评论中注意到其他客户有同样的问题，所以认为某处可能存在故障。

演示它在这里工作的地方：http：//vasterad.com/themes/sensation/index.html

这是 twitter.php 文件中的代码片段，这显然是我需要配置的唯一区域（为了安全起见，我省略了实际的访问令牌编号）：

    <?php
/**
* Usage:
* Send the url you want to access url encoded in the url paramater, for example (This is with JS):
* /twitter-proxy.php?url='+encodeURIComponent('statuses/user_timeline.json?screen_name=MikeRogers0&count=2')
*/
// The tokens, keys and secrets from the app you created at https://dev.twitter.com/apps
$config = array(
'oauth_access_token' => 'token-here',
'oauth_access_token_secret' => 'token-here',
'consumer_key' => 'token-here',
'consumer_secret' => 'token-here',
'use_whitelist' => true, // If you want to only allow some requests to use this script.
'base_url' => 'http://api.twitter.com/1.1/'
);
/*
* Ok, no more config should really be needed. Yay!
*/
// We'll get the URL from $_GET[]. Make sure the url is url encoded, for example encodeURIComponent('statuses/user_timeline.json?screen_name=MikeRogers0&count=10&include_rts=false&exclude_replies=true')
if(!isset($_GET['url'])){
die('No URL set');
}
$url = $_GET['url'];

if($config['use_whitelist'] && !isset($whitelist[$url])){
die('URL is not authorised');
}
// Figure out the URL parmaters
$url_parts = parse_url($url);
parse_str($url_parts['query'], $url_arguments);
$full_url = $config['base_url'].$url; // Url with the query on it.
$base_url = $config['base_url'].$url_parts['path']; // Url with the query.
/**
* Code below from http://stackoverflow.com/questions/12916539/simplest-php-example-retrieving-user-timeline-with-twitter-api-version-1-1 by Rivers

*/
function buildBaseString($baseURI, $method, $params) {
$r = array();
ksort($params);
foreach($params as $key=>$value){
$r[] = "$key=" . rawurlencode($value);
}
return $method."&" . rawurlencode($baseURI) . '&' . rawurlencode(implode('&', $r));

$oauth_signature = base64_encode(hash_hmac('sha1', $base_info, $composite_key, true));
$oauth['oauth_signature'] = $oauth_signature;
// Make Requests
$header = array(
buildAuthorizationHeader($oauth),
'Expect:'
);

//CURLOPT_POSTFIELDS => $postfields,

$feed = curl_init();
curl_setopt_array($feed, $options);
$result = curl_exec($feed);
$info = curl_getinfo($feed);
curl_close($feed);
// Send suitable headers to the end user.
if(isset($info['content_type']) && isset($info['size_download'])){
header('Content-Type: '.$info['content_type']);
header('Content-Length: '.$info['size_download']);
}
echo($result);
?>

希望有人能帮忙！

Answer 1

通过在PHP文件上查看对Twitter响应的请求的网站，您的请求似乎需要建立安全连接。所以，我的猜测是：

1. 通过 https 连接

将变量$config上的base_url密钥更改为 https。

$config = array(
    'oauth_access_token' => 'token-here',
    'oauth_access_token_secret' => 'token-here',
    'consumer_key' => 'token-here',
    'consumer_secret' => 'token-here',
    'use_whitelist' => true,
    'base_url' => 'https://api.twitter.com/1.1/' //was http://api.twitter.com/1.1/
);

2. 添加 CA（证书颁发机构）证书文件

如果我的第一个猜测没有解决任何问题，在 cURL 请求中添加 CA 证书可能会有所帮助。首先，从这里获取您自己的cacert.pem。将其保存在您可以识别的路径上。然后只需将 cURL 选项CURLOPT_SSL_VERIFYPEER设置为 true，您也可以选择将 CURLOPT_SSL_VERIFYHOST 显式设置为其默认值 2。

例如，根据您的代码段，保存在与您的Twitter cURL PHP文件相同的路径中。

$options = array(
    CURLOPT_CAINFO => __DIR__ . '/cacert.pem', //or dirname(__FILE__) . '/cacert.pem' for PHP < 5.3
    CURLOPT_HTTPHEADER => $header,
    //CURLOPT_POSTFIELDS => $postfields,
    CURLOPT_HEADER => false,
    CURLOPT_URL => $full_url,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYHOST => 2,
    CURLOPT_SSL_VERIFYPEER => true,
);

作为一个选项，您还可以在 php.ini 配置文件中预定义 cacert.pem。只需添加/编辑以下行，也不要忘记路径

curl.cainfo = "some/path/cacert.pem"
