急:用snoopy抓取EMS验证码,远程模拟查询单号,无法获取JSessionID的问题?
会员life169之前在PHP版块发过一篇文章叫(用snoopy抓取EMS验证码,远程模拟查询单号,取得查询结果)
链接是:http://topic.csdn.net/u/20100715/23/d58f2006-40ea-4cab-82e3-3bbcf4cd1e9f.html


可是我在测试的过程中却遇到一个问题,JsessionID,经常会取不到,

session_start(); 
include("Snoopy.class.php"); 
$url = "http://www.ems.com.cn/qcgzOutQueryNewAction.do?reqCode=gotoSearch"; 
$url2 = "http://www.ems.com.cn/qcgzOutQueryNewAction.do"; 

$snoopy = new Snoopy;
$snoopy->fetch($url); //获取所有内容 
print_r($snoopy->headers);

打印头信息,返回的是:
Array ( [0] => HTTP/1.1 200 OK [1] => Content-Type: text/html; charset=GB2312 [2] => X-Powered-By: Servlet/2.4 JSP/2.0 [3] => Accept-Ranges: bytes [4] => Connection: close [5] => Date: Tue, 15 Mar 2011 11:24:53 GMT [6] => Age: 1876 [7] => Content-Length: 22804 ) 

正确的返回信息应当是:
Array ( [0] => HTTP/1.1 200 OK [1] => Cache-Control: no-cache="set-cookie" [2] => Connection: close [3] => Date: Fri, 11 Mar 2011 07:42:04 GMT [4] => Content-Type: text/html; charset=GB2312 [5] => Set-Cookie: JSESSIONID=N5SMs1dMW1Wy8LJ48Z1ZhP1p2kS1GSgY5twTNxcYpz1MvgYZk0LQ!195316506; path=/ [6] => X-Powered-By: Servlet/2.4 JSP/2.0 ) 

前面返回的里面没有JSESSIONID, 导致在后面的查询中返回不了查询结果, 我已经整了2天了,在网上查了大量资料,还是没有头绪,现在有一个奇怪现象,如果在浏览器打开ems.php页面,过一段时间再刷新页面后,又会返回正确的headers信息,但是过一阵又不能正确返回,为什么会出现这种情况, 希望有大虾能帮我看看是怎么回事? 急
