我有这个奇怪的错误， CURL ERROR: Recv failure: Connection reset by peer

这就是它发生的方式，如果我没有连接到服务器并突然试图通过PHP中的CURL连接到服务器我得到错误 . 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 . 所以似乎连接是空闲的，然后突然服务器唤醒然后工作然后再次睡眠 .

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，我会很感激!!!

如果我详细说明输出，看看会发生什么

curl_setopt ($c, CURLOPT_VERBOSE, TRUE);

curl_setopt($c, CURLOPT_STDERR, $fp);

我得到以下内容

我在下面的脚趾中添加了删除默认 Headers 但仍然没有运气：

curl_setopt ($c, CURLOPT_HTTPHEADER, array( 'Expect:' ) );
