我遇到了这个奇怪的错误，CURL ERROR: Recv failure: Connection reset by peer
这就是它的发生方式，如果我没有连接到服务器并且突然尝试通过 PHP 中的 CURL 连接到服务器，我会收到错误消息。当我再次运行 CURL 脚本时，错误消失，然后一直运行良好，如果我让远程服务器空闲大约 30 分钟或重新启动远程服务器并尝试再次连接，我再次收到错误。所以看起来连接是空闲的，然后服务器突然醒来，然后工作，然后再次休眠。
这就是我的 CURL 脚本的外观。
$url = Yii::app()->params['pdfUrl'];
$body = 'title='.urlencode($title).'&client_url='.Yii::app()->params['pdfClientURL'].'&client_id='.Yii::app()->params['pdfClientID'].'&content='.urlencode(htmlentities($content));
$c = curl_init ($url);
$body = array(
"client_url"=>Yii::app()->params['pdfClientURL'],
"client_id"=>Yii::app()->params['pdfClientID'],
"title"=>urlencode($title),
"content"=>urlencode($content)
);
foreach($body as $key=>$value) { $body_str .= $key.'='.$value.'&'; }
rtrim($body_str,'&');
curl_setopt ($c, CURLOPT_POST, true);
curl_setopt ($c, CURLOPT_POSTFIELDS, $body_str);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($c, CURLOPT_CONNECTTIMEOUT , 0);
curl_setopt ($c, CURLOPT_TIMEOUT , 20);
$pdf = curl_exec ($c);
$errorCode = curl_getinfo($c, CURLINFO_HTTP_CODE);
$curlInfo = curl_getinfo($c);
$curlError = curl_error($c);
curl_close ($c);
我完全没有想法和解决方案，请帮助，我将不胜感激！！！
如果我详细说明输出以查看使用时会发生什么
curl_setopt ($c, CURLOPT_VERBOSE, TRUE);
curl_setopt($c, CURLOPT_STDERR, $fp);
我得到以下

我在以下脚趾中添加了删除默认标题，但仍然没有运气：
curl_setopt ($c, CURLOPT_HTTPHEADER, array( 'Expect:' ) );
