方法一:

function request_by_other($remote_server,$post_string){
    $context = array(  
    'http'=>array(  
        'proxy'=>'127.0.0.1:8787', // 代理IP
        'request_fulluri'=>true, // 是否使用代理
        'method'=>'POST',  
        'header'=>'Content-type: application/x-www-form-urlencoded'."\r\n".  
            'User-Agent : Jimmy\'s POST Example beta'."\r\n".  
            'Content-length: '.strlen($post_string)+8,  
        'content'=>'article_id='.$post_string)  
    );  
    $stream_context = stream_context_create($context);  
    $data = @file_get_contents($remote_server,FALSE,$stream_context);  
    return $data;  
} 

$remote_server = "http://www.xxxxx.com/article/yj/views.jhtml";
$post_string = "10898";

var_dump(request_by_other($remote_server, $post_string));

方法二:

function curl_string ($url,$user_agent,$proxy){
    $ch = curl_init();
    if (!empty($proxy)) { // 有代理IP就使用代理
        curl_setopt ($ch, CURLOPT_PROXY, $proxy); // 使用代理IP
        // 伪造客户端来源IP
        $xforip = rand(1, 254).".".rand(1, 254).".".rand(1, 254).".".rand(1, 254);
        curl_setopt ($ch, CURLOPT_HTTPHEADER, array('CLIENT-IP:'.$xforip, 'X-FORWARDED-FOR:'.$xforip));
    }
    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_POSTFIELDS, 'article_id=10898');
    curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent); //模拟用户使用的浏览器
    curl_setopt ($ch, CURLOPT_COOKIEJAR, dirname(__FILE__)."\cookie.txt");
    // curl_setopt ($ch, CURLOPT_HEADER, 1); //输出头信息
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转
    curl_setopt ($ch, CURLOPT_AUTOREFERER, 1 ); // 自动设置Referer
    curl_setopt ($ch, CURLOPT_TIMEOUT, 120);
    $result = curl_exec ($ch);
    curl_close($ch);

    return $result;

}

$url_page = "http://www.xxxxxx.com/article/yj/views.jhtml";
$user_agentArray = array(
    "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36",
);

$proxyArray = array(
    "http://125.39.68.180:80",
    "http://111.206.81.248:80",
);

$proxy = empty($proxyArray) ? "" : $proxyArray[rand(0, count($proxyArray) - 1)];
$user_agent = $user_agentArray[rand(0, count($user_agentArray) - 1)];

var_dump(curl_string($url_page,$user_agent, $proxy));
