這是PHP配置我用

function getHeaders() 
{ 
    $headers = array(); 
    $headers[] = 'Cache-Control: no-cache'; 
    $headers[] = 'Connection: Keep-Alive'; 
    $headers[] = 'Keep-Alive: 600'; 
    $headers[] = 'Accept-Language: en-us'; 
    $headers[] = 'X-CSRFToken: SeN9bHryRK8FWLTLJIs5c6u9AZ47a8pR'; 

    $headers[] = 'Content-Type: application/x-www-form-urlencoded'; 
    $headers[] = 'Origin: https://domain.com'; 
    $headers[] = 'Referer: https://domain.com'; 

    return $headers; 

} 

curl_setopt($connection, CURLOPT_URL, $url); 
    curl_setopt($connection, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($connection, CURLOPT_FOLLOWLOCATION, true); 
    curl_setopt($connection, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

    curl_setopt($connection, CURLOPT_COOKIEJAR, 'cookie.txt'); 
    curl_setopt($connection, CURLOPT_CONNECTTIMEOUT ,550000000); 
    curl_setopt($connection, CURLOPT_TIMEOUT, 5500000000); //timeout in seconds 
    curl_setopt($connection, CURLOPT_HTTPHEADER, getHeaders()); 
    curl_setopt($connection, CURLOPT_VERBOSE, 1);

你是否碰到負載平衡器或者像miracloud這樣的DDOS保護的服務器？他們可能會出於安全原因關閉長連接，即使您有數據流 – Bolovsky

我無法控制遠程服務器。但它加載完美鉻.. –

好的，經過一些搜索和IRC聊天之後，我發現瞭解決方案，但並非100％確定原因是什麼。看起來保持活力不足以保持連接。將在這裏發佈解決方案，希望我可以幫助別人。

什麼幫助對我來說是增加

--keepalive-time 2

捲曲選項的說明

--keepalive-time <seconds>

此選項設置的連接需要發送存活探測之前保持空閒的時間，個人保活探針之間的時間。它目前在提供TCP_KEEPIDLE和TCP_KEEPINTVL套接字選項（即Linux，最近的 AIX，HP-UX和更多）的操作系統上有效。如果使用--no-keepalive爲，則此選項無效。（在7.18.0中增加）

如果多次使用此選項，將使用最後一個。如果未指定，則該選項默認爲60秒。

看起來像默認值太高，不能保持我的連接打開。

下面是完整的命令我用我的電話

curl URL -H 'Accept-Encoding: gzip, deflate, sdch' -H 'Accept-Language: en-US,en;q=0.8,et;q=0.6,nl;q=0.4' -H 'Upgrade-Insecure-Requests: 1' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Connection: keep-alive' --compressed -v --keepalive-time 2

而且我在OSX

curl 7.43.0 (x86_64-apple-darwin15.0) libcurl/7.43.0 SecureTransport zlib/1.2.5 
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp 
Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz UnixSockets

運行此版本捲曲如果有人想在PHP中使用此選項curl，--keepalive-time選項自PHP 5.5起可用。你可以使用它如下：

curl_setopt($connection, CURLOPT_TCP_KEEPALIVE, 1); 
curl_setopt($connection, CURLOPT_TCP_KEEPIDLE, 2);

希望這可以幫助有人在同一個問題掙扎！

如何添加'CURLOPT_TCP_KEEPALIVE'＆'CURLOPT_TCP_KEEPIDLE'在PHP'Guzzle/HttpClient'？ – 2016-04-29 18:15:49

@ user6067756您只需將它們作爲捲髮設置傳遞：https：//justrocketscience.com/post/guzzle-transfer-closed-n-bytes-remaining-read – NaN

的libcurl只告訴你，連接被服務器在不潔淨的方式它並沒有提供它曾答應做數據削減。看起來分塊編碼並不表示傳輸結束。

瀏覽器因爲在接收到的內容時非常自由而臭名昭着，所以他們忽略了這些違反協議的行爲，並且違反了libcurl的規定。

遇到類似的問題，我的服務器在nginx後面。捲曲能夠，如果它直接連接到服務器，以接收響應，但是如果捲曲連接到經由nginx的服務器，捲曲投擲下面誤差

「會話*傳遞以優異的讀出的數據的剩餘*截止連接0捲曲關閉：（18 ）轉讓封閉以優異的讀取數據剩餘

當我連接到使用瀏覽器相同的nginx的URL，響應是顯示了罰款，這是很奇怪的，當我試圖使用curl連接到同一個nginx的URL，它被扔以上錯誤

比較瀏覽器和curl發送的報頭後發現，瀏覽器能夠接收因爲低於報頭的響應，其捲曲不發送

'Accept-Encoding: gzip'

使用捲曲以上標頭中發送，它工作正常。所以，上面的頭文件正在壓縮對gzip的響應，從而減少響應大小。

經過多次挖掘，發現nginx無法發送> 80kb的任何有效載荷。浪費大量的時間後，發現問題是與nginx的緩衝和nginx的在nginx.conf添加以下proxy_buffering財產

location/{ 
proxy_buffering off; 
}

接受的答案並沒有解決我的問題後，工作就像魅力。寫下這個答案，以便任何人如果面臨與我一樣的問題，就不必浪費時間。
