PubSubHubbub 确认订阅时出错
我使用此代码：
<?php
if(isset($_GET["hub_challenge"])) {
echo $_GET["hub_challenge"];
}
else {
}
$ch = curl_init("http://pubsubhubbub.appspot.com");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,"hub.mode=subscribe&hub.verify=sync&hub.callback=http://rssreaderbg.net/pubsubbub/example/index.php&hub.topic=http://rssreaderbg.net/blog/?feed=comments-rss2");
curl_exec($ch);
file_put_contents("logmeme.txt",$HTTP_RAW_POST_DATA);
?><?php
if(isset($_GET["hub_challenge"])) {
echo $_GET["hub_challenge"];
}
else {
}
$ch = curl_init("http://pubsubhubbub.appspot.com");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,"hub.mode=subscribe&hub.verify=sync&hub.callback=http://rssreaderbg.net/pubsubbub/example/index.php&hub.topic=http://rssreaderbg.net/blog/?feed=comments-rss2");
curl_exec($ch);
file_put_contents("logmeme.txt",$HTTP_RAW_POST_DATA);
?>
但是 pubsubhubbub.appspot.com 的中心给我“尝试确认订阅时出错”，为什么？
I use this code:
<?php
if(isset($_GET["hub_challenge"])) {
echo $_GET["hub_challenge"];
}
else {
}
$ch = curl_init("http://pubsubhubbub.appspot.com");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,"hub.mode=subscribe&hub.verify=sync&hub.callback=http://rssreaderbg.net/pubsubbub/example/index.php&hub.topic=http://rssreaderbg.net/blog/?feed=comments-rss2");
curl_exec($ch);
file_put_contents("logmeme.txt",$HTTP_RAW_POST_DATA);
?><?php
if(isset($_GET["hub_challenge"])) {
echo $_GET["hub_challenge"];
}
else {
}
$ch = curl_init("http://pubsubhubbub.appspot.com");
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch,CURLOPT_POSTFIELDS,"hub.mode=subscribe&hub.verify=sync&hub.callback=http://rssreaderbg.net/pubsubbub/example/index.php&hub.topic=http://rssreaderbg.net/blog/?feed=comments-rss2");
curl_exec($ch);
file_put_contents("logmeme.txt",$HTTP_RAW_POST_DATA);
?>
But the hub at pubsubhubbub.appspot.com gives me "Error trying to confirm subscription" ,why?

最简单的解决方案是尝试自己执行订阅验证。
使用规范中所述的参数向您的回调发送 GET 请求。确保您的回调返回 2XX 并且仅回显集线器提供的
hub.challenge。The simplest solution is to try performing a subcription verification yourself.
Send a GET request to your callback with the params as explained in the spec. Make sure your callback returns a 2XX and only echoes the
hub.challengeprovided by the hub.
