httpclient模拟登陆(使用js设置cookie)
复制代码 代码如下:
<html>
<meta http-equiv='Content-Type' content='text/html; charset=gb2312'>
<link rel=stylesheet type=text/css href='https://www.jb51.net/bbs.css'>
<script>document.cookie='utmpnum=51;path=https://www.jb51.net/;domain=.' + window.location.host</script>
<script>document.cookie='utmpkey=20154732;path=https://www.jb51.net/;domain=.' + window.location.host</script>
<script>document.cookie='utmpuserid=yay;path=https://www.jb51.net/;domain=.' + window.location.host</script>
<meta http-equiv='Refresh' content='0; url=https://www.jb51.net/firstpage.php'>
h4ttpclient 4.3:
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：
复制代码 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("."); //这个网址对应的是<span>window.location.host的返回值</span>
cookie.setPath("https://www.jb51.net/");
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
复制代码 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。
