求高手,模拟浏览器抓取网页
如抓取http://map.sogou.com/api/这个网页,我写的程序,如果不带网址后面的"/",会抓取得不到,但是站上网(http://tool.chinaz.com/Tools/PageCode.aspx),不带最后面的"/"即可抓取到(即:http://map.sogou.com/api),他是什么原理?下面贴出我的代码,请改进

<br />
<br />
function file_get($url){<br />
	 ob_start();<br />
	 $ch = curl_init();<br />
	 <br />
	 curl_setopt($ch, CURLOPT_COOKIEJAR, "./cookie.txt");<br />
	 curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 2.0.50727; InfoPath.1; CIBA)");<br />
	curl_setopt($ch, CURLOPT_URL, $url);<br />
	 curl_setopt($ch, CURLOPT_HEADER, FALSE);<br />
	 curl_setopt($ch, CURLOPT_COOKIESESSION, TRUE);<br />
	 curl_setopt($ch, CURLOPT_NOBODY, FALSE);<br />
<br />
	 curl_exec($ch);<br />
	 curl_close($ch);<br />
	 $content = ob_get_clean();<br />
	 <br />
	 <br />
<br />
	return $content;<br />
<br />
}<br />
