我使用 Google 只是为了测试。allow_url_fopen在我的php.ini文件中启用。

You should use the PHP cURLextension if it's available, as it's many times faster, more powerful, and easier to debug. Here is an example that does the same thing you were trying:
您应该使用PHP cURL扩展（如果可用），因为它速度快许多倍、功能更强大且更易于调试。这是一个执行与您尝试相同的操作的示例：
function curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$feed = 'http://twitter.com/statuses/user_timeline.rss?screen_name=google&count=6';
$tweets = curl($feed);

Most probably, your server have mod_security enabled. Add the below lines in your .htaccess after any existing rules and then try to see the issue is still there, after that addition.
最有可能的是，您的服务器启用了 mod_security。在任何现有规则之后在 .htaccess 中添加以下几行，然后尝试在添加之后查看问题仍然存在。
<IfModule mod_security.c>
SecFilterScanPost
</IfModule>
