这段代码总是在2m左右出现504 Proxy Timeout错误,什么原因?
这段代码当$fucknum比较大时,比如1000时,就会出现504 Proxy Timeout错误,而且报错后程序不再继续执行,好像停止不前了,$fucknum值比较小时不会出现这个错误,什么原因?请各位指点下
function autonewnewegg($arr){ $fucknum=intval($arr['fucknum']); // # 获取抓取条数的整数值 $outime=$fucknum*2+100; set_time_limit($outime);//设置脚本执行时间 $nextnum=20;//连续查找10次不存在则终止 $sn=$arr['sn']; $acl=explode("-",$sn); $acl_1=preg_replace('/[^0-9]+/','',$acl[1]); //二次 $a=$b=0; //二次 while($fucknum>0){ $arr1 = $arr2 = array(); if($acl[2]<1000&&$acl_1<100){ $acl[2]=str_pad("$acl[2]",3,'0',STR_PAD_LEFT); $acl_1=str_pad("$acl_1",2,'0',STR_PAD_LEFT); $acl[1]="c".$acl_1; $arr_in=implode("-",$acl); $url=$GLOBALS['competitor'][1]['product'].$arr_in.'.htm'; if($acl[2]==999){ $acl_1=$acl_1+1; $acl[2]=001; }else { ++$acl[2]; } }elseif($acl[0]<=99){ $acl[0]=str_pad("$acl[0]",2,'0',STR_PAD_LEFT); $arr_in=implode("-",$acl); $acl[2]=001; $acl_1=01; ++$acl[0]; $url=$GLOBALS['competitor'][1]['product'].$arr_in.'.htm'; } $str = file_get_contents($url); if(!$str){ $fucknum--; }else{ $preg ='/href="http:\/\/www\.newegg\.com\.cn\/SubCategory\/(\d*)\.htm">/'; $preg2 ='/<h1>(.*)<\/h1>/'; $str = iconv("gbk","UTF-8",$str); preg_match($preg,$str,$arr1); preg_match($preg2,$str,$arr2); if(empty($arr1) || empty($arr2)){ $fucknum--; }else{ $price = $this->ocr_newegg($url); if ($price == false||$price=='.'){ $price = $this->ocr_newegg1($url); } if($price == false){ }else{ $autoarr=array('cid'=>$arr1[1],'name_newegg'=>$arr2[1],'price_newegg'=>$price,'sn_newegg'=>$arr_in); $this->addnew_newegg($autoarr); } $fucknum--; } } } return true; }

超时,就没办法了。
set_time_limit(0);
?
让脚本永不超时:set_time_limit(0);
超时,就没办法了。
set_time_limit(0);
?
已经设置了,$outime是根据$fucknum动态改变的啊,小数据量时怎么不超时,
set_time_limit($outime);//设置脚本执行时间
让脚本永不超时:set_time_limit(0); 设置了,还是会出现那个错误,不是这个原因
报:504 Proxy Timeout的原因很可能是
外网卡在收到了内网卡来自客户端的访问请求以后,在同一时间,马上转发给了目的地网站服务器,但是目的地网站服务器没有及时响应。3秒之后重发一次,6秒之后再重发一次,由于一直没有收到响应内网卡不得不返回给客户端HTTP/1.1 504 Proxy Timeout。

你可以在每次循环之后都sleep长点时间,看是否还有这样的现象出现!~应该是远程服务器的问题!
