重试超时CURL

Question

如果发生超时，重试卷曲请求的更好方法是什么？

我一直在使用邪恶GOTO

retry: 

$result = curlPost($ch, "something.php", $cookie, http_build_query($arg)); 

if (curl_errno($ch) == 28) { 
    goto retry; 
} 

// Do something 

在curlPost()功能想出了这个解决方案，有

curl_setopt($curl, CURLOPT_TIMEOUT, 3);

你可以使用一个do-while循环。

$count = 0; 
$max_tries = 5; 
$success = true; 
do { 
    $result = curlPost($ch, "something.php", $cookie, http_build_query($arg)); 
    $count++; 
    if($count >= $max_tries) { 
     $success = false; 
     break; 
    } 
} 
while(curl_errno($ch) == 28); 

if($success == false) { 
    // If it got here it tried 5 times and still didn't get a result. 
    // More code here for what you want to do... 
}
