循环HTTP后开始出现故障亚马逊SES

Question

我最初发布这个在亚马逊SES论坛在这里：https://forums.aws.amazon.com/thread.jspa?threadID=74561&tstart=0

但由于计算器社会更加活跃，我会在这里:)张贴

基本上我有一个围绕cURL帖子的forecah循环（请参阅脚本代码片段的帖子底部）。它适用于几百个帖子，但对其他所有人来说都会失败。这里的最后一次成功后接着是第一次不成功的职位100的的...

这里的脚本片段

foreach($JSONarray['DATABASE'] as $E) 
{ 
     if ((array_diff($E['LISTS'], $FILTER) != $E['LISTS']) && $E['STATUS'] == "CONF") 
     { 
     $MAIL = "Action=SendEmail&Source=".$FROME."&ReturnPath=".$BOUNCE."&Destination.ToAddresses.member.1=".$TOE."&Message.Subject.Data=".$SUBE."&Message.Body.Html.Data=".$BODYE;   
     //curl 
     $aws = curl_init(); 
     curl_setopt($aws, CURLOPT_POSTFIELDS, $MAIL); 
     curl_setopt($aws, CURLOPT_HTTPHEADER, $headers); 
     curl_setopt($aws, CURLOPT_HEADER, false); 
     curl_setopt($aws, CURLOPT_URL, $url); 
     curl_setopt($aws, CURLOPT_RETURNTRANSFER, true); 
     curl_setopt($aws, CURLOPT_VERBOSE, true); 
     curl_setopt($aws, CURLOPT_STDERR, $SESLOG); 
     curl_exec($aws); 
     curl_close($aws); 
     } 
} 

有任何想法吗？

我想通了这个问题：

<ErrorResponse xmlns="http://ses.amazonaws.com/doc/2010-12-01/"> 
<Error> 
<Type>Sender</Type> 
<Code>RequestExpired</Code> 
<Message>Request timestamp: Mon, 22 Aug 2011 15:49:11 UTC expired. It must be within 300 secs/ of server time.</Message> 
</Error> 
<RequestId>0e3899cb-ccd7-11e0-9f09-c5d12d442026</RequestId> 
</ErrorResponse> 

我的头都SET-在卷曲附近的forecah循环之外。卫生署！所以我只是将这些代码移入循环来解决超时问题。

Answer 2

它可能是一个DOS预防mecanism踢？如何在你的代码中加入一些睡眠？我肯定会放一些保护措施，制止潜在的DOS攻击，如果我是亚马逊..

只是一个猜测，但...
