URL：http://www.baidu.com/s?wd=site:www.cnblogs.com
代碼：

def get_html(url)
    uri = URI(url)
    p resp = Net::HTTP.get(uri)
end

而獲取到的結(jié)果是百度首頁的源碼，并不是搜索site:www.cnblogs.com的結(jié)果

不知道，Ruby中有關(guān)于網(wǎng)絡(luò)編程方面的好書籍沒？
剛接觸ruby，很多東西不知道從何找（目前都是到官網(wǎng)看文檔）。

使用PHP簡單實現(xiàn)了下：

<?php
set_time_limit(0);
function _rand()
{
    $length = 26;
    $chars = "0123456789abcdefghijklmnopqrstuvwxyz";
    $max = strlen($chars) - 1;
    mt_srand((double)microtime() * 1000000);
    $string = '';
    for ($i = 0; $i < $length; $i++) {
        $string.= $chars[mt_rand(0, $max) ];
    }
    return $string;
}
$HTTP_SESSION = _rand();
$HTTP_SESSION;
$HTTP_Server = "www.baidu.com";
$HTTP_URL = "/s?wd=site:www.cnblogs.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://" . $HTTP_Server . $HTTP_URL);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)");
$res = curl_exec($ch);
curl_close($ch);
print_r($res);
