Httpclient simulated login (set cookie using js)
The Code is as follows:
<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 way is to customize an httpclient through the cookie. Based on the example above, the method is as follows:
The Code 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"); // The URL corresponds to <span style = "font-family: Arial, Helvetica, sans-serif;"> window. location. host return value </span>
Cookie. setPath ("/");
CookieStore. addCookie (cookie );
}
// Set the store
CloseableHttpClient httpclient = HttpClients. custom ()
. Setdefacookcookiestore (cookieStore)
. Build ();
Android:
I haven't found the API corresponding to the above method for a long time. I can only add a cookie before each access.
The Code is as follows:
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 + = ";";
}
/*
* Network Access
*/
HttpGet httpget = new HttpGet (url );
Httpget. addHeader ("Cookie", cookie );
// If httpclient already has a cookie, you may need to set the httpclient cookie policy. For details, see the official API (:
HttpResponse response = httpclient.exe cute (httpget );
