我正在使用curl從URL檢索數據。curl返回「從對等方接收數據時失敗」
如果PHP代碼是通過HTTP請求調用的,或者URL是在Firefox中輸入的,那麼一切正常。如果從PHP CLI腳本執行完全相同的代碼,curl_exec將返回false。錯誤信息是「從對方接收數據時失敗」。
任何想法爲什麼捲曲不起作用?
當我設置捲曲輸出到長篇大論,我得到:
Setting curl to verbose gives:

* Trying 153.46.254.70... * Closing connection #0
* Failure when receiving data from the peer
這是代碼:
// if curl is not installed we trigger an alert, and exit the function
if (!function_exists('curl_init')){
watchdog('sixtk_api', 'curl is not installed, api call cannot be executed',array(),WATCHDOG_ALERT);
return $this;
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $this->request);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 180);
// Download the given URL, and return output
$output = curl_exec($ch);
if (!$output) {
$error = curl_error($ch);
echo($error);
}
// Close the cURL resource, and free system resources
curl_close($ch);
您提供的代碼不完整。請將其降至所需的最小值以顯示您的案例:刪除'$ this'依賴項,而不是'watchdog'函數調用,只需'die()'。否則,這裏的人不能重現你的問題。有問題的URL也丟失。 – hakre
對不起,我不能發佈URL,因爲我必須保密(這不是我的決定!)。 – BetaRide
畢竟,我認爲從cli和通過Web服務器調用curl是有區別的嗎? – BetaRide
