很抱歉这个问题,但是我已经3天不知道错误在哪里了。我在自己的网站上有一个页面,其中显示了用户的IP地址,如下所示:
<?php
echo "<br>"."Your IP address :"."<br>";
echo @$_SERVER['HTTP_CLIENT_IP']."<br>";
echo @$_SERVER['HTTP_X_FORWARDED_FOR']."<br>";
echo @$_SERVER['REMOTE_ADDR']."<br>"
?>
并且当我仅通过curl发送一个请求时,此页面将完全按照我的意愿显示代理的地址:
$ch = curl_init("http://mysite/youIp.php");
$proxy = '180.210.205.107:3128';
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$curl_scraped_page = curl_exec($ch);
$result = curl_exec($ch);
echo $result;
curl_close($ch);
结果:
但是当我尝试通过curl函数使用多个请求时,所有操作都会失败:
$proxy = '180.210.205.107:3128';
function multirequest($urls)
{
$multi = curl_multi_init();
$handles = [];
$htmls = [];
for($i=0; $i<count($urls);$i++)
{
$url = $urls[$i];
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_multi_add_handle($multi, $ch);
$handles[$url] = $ch;
}
do {
$mrc = curl_multi_exec($multi, $active);
} while ($mrc == CURLM_CALL_MULTI_PERFORM);
while ($active && $mrc == CURLM_OK)
{
if (curl_multi_select($multi) == -1)
{
usleep(1);
}
do
{
$mrc = curl_multi_exec($multi, $active);
}while($mrc == CURLM_CALL_MULTI_PERFORM);
}
foreach($handles as $channel)
{
$html = curl_multi_getcontent($channel);
$htmls[] = $html;
curl_multi_remove_handle($multi, $channel);
}
curl_multi_close($multi);
return $htmls;
}
运行来自数组的url请求(实际上,$urls
仅包含1个url-到我自己的页面):
var_dump($urls);
// only 1 url -> http://mysite/youIp.php
foreach($urls as $url)
{
$htmls = multirequest($url);
foreach($htmls as $html)
{
echo $html;
}
}
结果是,我看到了我的服务器IP地址:
我不知道为什么这段代码不起作用。如果您发现我在哪里弄错了,请提供帮助。谢谢!
答案 0 :(得分:0)
也许改变这个
$proxy = '180.210.205.107:3128';
function multirequest($urls)
{
$multi = curl_multi_init();
$handles = [];
$htmls = [];
// ...
对此
function multirequest($urls)
{
$proxy = '180.210.205.107:3128';
$multi = curl_multi_init();
$handles = [];
$htmls = [];
// ...
换句话说,在函数内部定义$proxy
