httpclient模拟登陆具体实现(使用js设置cookie)

httpclient模拟登陆(使用js设置cookie)

代码如下:

<html> 
<meta http-equiv='Content-Type' content='text/html; charset=gb2312'> 
<link rel=stylesheet type=text/css href='/bbs.css'> 
<script>document.cookie='utmpnum=51;path=/;domain=.' + window.location.host</script> 
<script>document.cookie='utmpkey=20154732;path=/;domain=.' + window.location.host</script> 
<script>document.cookie='utmpuserid=yay;path=/;domain=.' + window.location.host</script> 
<meta http-equiv='Refresh' content='0; url=/firstpage.php'>

最简单的方法就是通过得到的cookie定制一个httpclient,根据上面的例子,方法如下:

代码如下:

CookieStore cookieStore = new BasicCookieStore(); 

for (int i = 0; i < 3; i++) { 
String name; 
String value; 
int flag=s.indexOf("document.cookie"); 
s=s.substring(flag+17); 
flag=s.indexOf('='); 
name=s.substring(0, flag); 
value=s.substring(flag+1, s.indexOf(';')); 
BasicClientCookie cookie = new BasicClientCookie(name, 
value); 
cookie.setVersion(0); 
cookie.setDomain(".www.zju88.org"); //这个网址对应的是<span style="font-family: Arial, Helvetica, sans-serif;">window.location.host的返回值</span> 
cookie.setPath("/"); 
cookieStore.addCookie(cookie); 
} 
// Set the store 
CloseableHttpClient httpclient = HttpClients.custom() 
.setDefaultCookieStore(cookieStore) 
.build();

我找了半天也没找到上面方法对应的API,只能在每次访问前加cookie了

代码如下:

String cookie=""; 
for (int i = 0; i < 3; i++) { 
String name; 
String value; 
int flag=s.indexOf("document.cookie"); 
s=s.substring(flag+17); 
flag=s.indexOf('='); 
name=s.substring(0, flag); 
value=s.substring(flag+1, s.indexOf(';')); 
cookie +=name +"="+value; 
if(i!=2) 
cookie+=";"; 
} 

/* 
* 每次访问网络 
*/ 
HttpGet httpget = new HttpGet(url); 
httpget.addHeader("Cookie",cookie); 
//如果httpclient中已经有cookie可能需要设置httpclient的cookie策略,具体可查官方API (: 
HttpResponse response = httpclient.execute(httpget);

ps:如果是用java SE,也可以使用htmlunit类,它会执行js。
