I need to get the HttpOnly cookies set as Session cookie in my java code.
To get non HttpOnly cookies I used Jsoup but now am stucked with HttpOnly cookies ?
Note :
Don't know if it matters but the site from which I want to get HttpCookies is developed in ASP.net.
I would expect Jsoup to make those available:
Connection connection = Jsoup.connect("http://example.com");
Connection.Response response = connection.execute();
...then use the cookies map on response.
If the HttpOnly cookies aren't there, you may have to read the contents of the URL directly (e.g., via URLConnection or similar) before passing them on to JSoup.parse, and look for the cookie headers in that stream.
Side note: To get a Document after connecting as with the above, without repeating the request, use Connection#parse:
Document doc = connection.parse();
I just mention this because you're likely to want the document as well as the cookies.

I am using spring security with angular 6. When i login using basic Auth server sends a cookie JessionID with response. I want to send this cookie with other request for authentication purpose but it gives me error Refused to set unsafe header 'Cookie' . When i hit the same endpoint from postman with same cookie in header it works.
Below is the method in angular:
Note: Currently i am manually adding it with headers.
private heroesUrl = 'http://localhost:8080/hi';
header = new HttpHeaders().set("Cookie", "JSESSIONID=A2A75EC9A3E1172D60060C6E708549B5");
getMessage() :Observable<Message>{
return this.http.get<Message>(this.heroesUrl,{headers:this.header});
}
Response which i get when i login using basic Auth
You can't do this, cause the browser doesn't allow you to do it. Let me describe the problem here:
Did you notice the Set-Cookie: JSESSIONID=......; Path=/; HttpOnly in your response headers? Well, The problem is the HttpOnly flag. Actually :) it's not a problem, it's a feature to prevent attacks that aim to steal your browser cookies:
HttpOnly is a flag added to cookies that tell the browser not to display the cookie through client-side scripts (document.cookie and others). ... When you set a cookie with the HttpOnly flag, it informs the browser that this special cookie should only be accessed by the server
So the browser doesn't allow any javascript code to access this variable. If you could change that value, then it's not a HttpOnly flagged cookie anymore:)
If you want to send this cookie via javascript, you should send it via the Authorization header for example and write middleware in Java server so that it captures these values from the Authorization header and think of them as JSESSIONID cookie. No more options for you :)
I also had this issue, and i just fixed it right now.
I realized that is you pass option {withCredentials: true} your browser will automatically send all available cookies along with your request. That way you don't have to add the cookies manually, so it's fluent and i thinks it also safer.
Change your code to this and see and check.
Cookies are available when the path is same as your front end.
private heroesUrl = 'http://localhost:8080/hi';
getMessage() :Observable<Message>{
return this.http.get<Message>(this.heroesUrl, {withCredentials: true});
}
so I am using Jsoup and I am trying to get the cookies set for the site subdomain. The Connection.Response#cookies only returns the one set for that domain. I would like to grab the cookies so that I can use them to request data from the subdomain.
Example:
Connection.Response res = Jsoup.connect("https://www.tvplayer.com/watch/dave").userAgent("Mozilla/5.0").timeout(10000).method(Connection.Method.GET).execute();
Document doc = Jsoup.connect("https://live.tvplayer.com/").timeout(10000).cookies(res.cookies()).get();
If you request it throws a 403 due to the cookie not being set, this is because the cookies for the response doesn't have the ones from the subdomain live. just the main domain.
Outputting the cookies gives the cookies AWSELB and PHPSESSID only.
I have a problem when used HttpURLConnection in Java, The connection to rest server give client cookie after authenticated. I can save the cookies from response header (Set-Cookie) after requesting and use them for next request but cookies that has !httponly flag is not available in response header (Set-Cookie).
I need the session_id cookie with !httponly flaged to be sent to next request so the connection no need to be authenticated in next request after the app exiting.
How can I save all cookies (basic cookies, secure cookies, httponly cookies) in Java just like cURL does?
After searching for a long time, I found the solution: http://jaunt-api.com/
I realize this question is old, but it was the first answer that came up in an internet search.
To resolve, use CookieHandler.setDefault( new CookieManager( null, CookiePolicy.ACCEPT_ALL ) ); per here: Should HttpURLConnection with CookieManager automatically handle session cookies?
I access a webpage by passing the session id and url and output is a HTML response.
I want to use jSoup to parse this response and get the tag elements.
I see the examples in Jsoup takes a String for establishing connection. How do i proceed.
pseudo code:
I tried the above method and got this exception
java.io.IOException: 401 error loading URL http://www.abc.com/index
at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:387)
at org.jsoup.helper.HttpConnection$Response.execute(HttpConnection.java:364)
at org.jsoup.helper.HttpConnection.execute(HttpConnection.java:143)
at org.jsoup.helper.HttpConnection.get(HttpConnection.java:132)
Basically the entity.getContent() has the HTML response which has to be passed as a String to the connect method. But it doesn't work.
Apache Commons HttpClient and Jsoup do not share the same cookie store. You basically need to pass the very same cookies as HttpClient has retrieved back through Jsoup's Connection. You can find some concrete examples here:
Sending POST request with username and password and save session cookie
how to maintain variable cookies and sessions with jsoup?
Alternatively, you can also just continue using HttpClient for firing HTTP requests and maintaining the cookies and instead feeds its HttpResponse as String through Jsoup#parse().
So this should do:
HttpResponse httpResponse = httpclient1.execute(httpget, httpContext);
String html = EntityUtils.toString(httpResponse.getEntity());
Document doc = Jsoup.parse(html, testUrl);
// ...
By the way, you do not necessarily need to create a whole new HttpClient for a subsequent request. Just reuse httpclient which you already created. Also your way of obtaining the response as String is clumsy. The second line in the above example shows how to do it at simplest.
It shows an http error 401 which means
Similar to 403 Forbidden, but specifically for use when authentication is possible but has failed or not yet been provided.
Therefore, i think you need to login into the website using your java code or identify yourself by sending cookies through your code.
How can I get a cookie from a web page using Java? I mean only Java not with Servlets or etc..
You can use java.net.URLConnection for this. It offers a getHeaderFields() method to get the response headers. The cookies are set by Set-Cookie header.
URLConnection connection = new URL("http://google.com").openConnection();
List<String> cookies = connection.getHeaderFields().get("Set-Cookie");
// ...
You can either get the cookies from the header,
or you can use Apache commons and use their functionality.
