Httpclient mock login (using js to set cookie)
H4ttpclient 4.3:
The simplest method is to customize an httpclient through the obtained cookie. According to the above example, the method is as follows:
Android:
I searched for a long time but could not find the API corresponding to the above method, so I had to add cookie before each access
Ps: if you are using Java SE, you can also use the htmlunit class, which executes js.
<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'>
H4ttpclient 4.3:
The simplest method is to customize an httpclient through the obtained cookie. According to the above example, the method is as follows:
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"); //This url corresponds to <Span style="font-family: Arial, Helvetica, sans-serif;> Return value of window.location.host </ span>
cookie.setPath("/");
cookieStore.addCookie(cookie);
}
// Set the store
CloseableHttpClient httpclient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.build();
Android:
I searched for a long time but could not find the API corresponding to the above method, so I had to add cookie before each access
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+=";";
}
HttpGet httpget = new HttpGet(url);
httpget.addHeader("Cookie",cookie);
//If there is already a cookie in httpclient, it may be necessary to set the cookie policy of httpclient. For details, please refer to the official API (:
HttpResponse response = httpclient.execute(httpget);
