Question

How do I manage cookies with HttpClient in Android and/or Java?

Answer 1

+1 A:

You need to use HttpContext. Set cookie store to context and pass context long with HttpGet/HttpPost in execute method. Hope this should help.

See example: Complete code can be found here

   // Create a local instance of cookie store
    CookieStore cookieStore = new BasicCookieStore();

    // Create local HTTP context
    HttpContext localContext = new BasicHttpContext();
    // Bind custom cookie store to the local context
    localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

    HttpGet httpget = new HttpGet("http://www.google.com/"); 

    System.out.println("executing request " + httpget.getURI());

    // Pass local context as a parameter
    HttpResponse response = httpclient.execute(httpget, localContext);

Ok, how would I go about getting the header? Do I take it from the response, such as, response.getHeader("Set-Cookie")? Because I have tried to do something similar but there is only a getHeaders(); method which I guess returns an array? I'd have to look it up again.

Ok I managed to use the Header[] object and have successfully set the headers including the Cookie header but that didn't seem to solve my issue. I have edited my question with code that DOES work that I made, but for some reason as I moved it over to my actual application it broke. FYI the working code does nothing with headers, it just works? lol

Ok ;) I managed to find something which I see missing from your code and updated (rather changed ) my answer.

I appreciate the quick responses. I added the missing code but still no luck. Could splitting up the GET and POST section into 2 different methods somehow cause the client to no retain a session?

did you try to set cookiestore to HttpContext and passing HttpContext along with your method in execute of httpclient ?

YoK 2010-08-28 07:17:16

Yep, I created a method that sets the CookieStore to the context, and then made sure that I passed along the context client.execute(request, local context), but still no luck. I have no idea what it is at this point.

Strange... I am out now but will certainly give it a try sometime in next few days (when I am back). Can you post updated code ?

YoK 2010-08-28 08:28:19

Yes I will do just that, again I appreciate the help.

Alejandro Huerta 2010-08-28 08:43:55

In your code I don't see "setContext" defined being called anywhere ?Also why everything in your class static ? If this is only for testing then its fine.

setContext is called from the main activity at startup. It calls these methods in this order, setContext(); and getPage(url); at onCreate. Then when I press the login button, postPage(params, host, action). At compile I get a, cannot make a static reference to non static method, when I do HTTP.getPage(url), therefore the static.

Alejandro Huerta 2010-08-29 16:30:00

I've since edited and updated my code and have gotten rid of all static declarations. Everything compiles and runs, but of course no luck with the session issue.

Answer 2

A:

I was unable to get my own code working (I might work on it again later), but I found useful code here http://stackoverflow.com/questions/874227/android-project-using-httpclient-http-client-apache-post-get-method and I am using the class built by Charlie Collins, which is similar to the Http Code in the ZXing Android example. I may eventually move to the ZXing code.
