Question

我有以下CURL代码：

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url);
if ($postParameters != '') {
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $postParameters);
}
curl_setopt($ch, CURLOPT_COOKIEFILE, __DIR__.'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, __DIR__.'/cookie.txt');
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_TIMEOUT, 60); 
curl_setopt($ch, CURLOPT_REFERER, $referer);
$pageResponse = curl_exec($ch); 
curl_close($ch);

当我尝试获取页面时，大部分时间我都会收到我要求的整个页面。但是，我不时会得到页面的一部分，例如：

DOCTYPE html PUBLIC“ - // W3C // DTD XHTML 1.0 Transitional // EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd” ＆GT; HTML xmlns =“http://www.w3.org/1999/xhtml”dir =“ltr”lang =“en”＆gt;头＆GT; meta http-equiv =“Content-Type”content =“text / html; charset = windows-1251“/＆gt; meta name =”generator“content =”

我删除了“＆lt;”在标签前面，HTML代码将显示在堆栈交换中。有谁知道为什么突然停止接收？我注意到数据经常在打开双引号后突然停止（即content =“或username =”）。不确定100％是否总是以这种方式发生。无论如何，这可能是编码问题吗？还有其他想法吗？

任何帮助都将不胜感激。

You can try to add some debugging.

Add these options:

curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_STDERR,$f = fopen(__DIR__ . "/error.log", "w+"));

And these before curl_close():

if($errno = curl_errno($ch)) {
    $error_message = curl_strerror($errno);
    echo "cURL error ({$errno}):\n {$error_message}";
}

If that doesn't work try increasing the timeout and see if it goes away:

curl_setopt($ch, CURLOPT_TIMEOUT, 300);

If the timeout increase works, then find out why.
