Probably this is often problem, but I can’t solve it.
I need to automaticallly fill out some fields on the web form, which is given from server.
I use Apache HttpClient to make more easy my life)
By now, one can consider my steps to acheive the aim:

http://trac.edgewall.org/

2. I locally use Trac without any SSL(SSL tunnel). (It’s not difficult to change my program to be able to use HTTPS).

3. By now, I can authenticate and perform GET request, but I can’t perform POST request

http://localhost:8000/tracenvir/newticket

http://s04.radikal.ru/i177/0912/cb/d43971cebc02.png

“input type=”text” id=”field-summary” name=”field_summary” size=”70″ “

“textarea id=”field-description” name=”field_description” class=”wikitext” rows=”10″ cols=”68″/textarea”‘

5. So, I write this:


        int status = 0;
        int cookLength=0;
        Cookie[] cookies = null;

        HttpClient client = new HttpClient();
        client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
        HttpState initialState = new HttpState();
        client.setState(initialState);

        //**********//
        //**Log in**//
        //**********//

        GetMethod login = new GetMethod("http://localhost:8000/tracenvir/login");
        client.getState().setCredentials(AuthScope.ANY,
                new UsernamePasswordCredentials("rauch", "qwert"));
        login.setDoAuthentication(true);
        System.setProperty("javax.net.ssl.trustStore", "/home/rauch/NetBeansProjects/jssecacerts");

        try {
            status = client.executeMethod(login);

        System.out.println("response code = "+status);
        cookies = client.getState().getCookies();
        cookLength = cookies.length;

        for(int i=0;i (less than) cookLength;i++) {
            System.out.println(cookies[i].toString());
        }
        login.releaseConnection();
        } catch(IOException ex) {
            ex.printStackTrace();
        }


        //*********************//
        //**Create New Ticket**//
        //*********************//

        PostMethod post = new PostMethod("http://localhost:8000/tracenvir/newticket");

        NameValuePair[] data = {
            new NameValuePair("field-summary","second error"),
            new NameValuePair("field-descryption","Some stupid descryption..."),
            new NameValuePair("field-type","defect"),
            new NameValuePair("field-priority","major"),
            new NameValuePair("field-version","1.0"),
            new NameValuePair("field-owner","moscow server"),
            new NameValuePair("submit","create ticket"),
        };


        //post.setRequestBody(data);
        post.addParameters(data);
        post.addRequestHeader("Referer","http://localhost:8000/tracenvir/login");
        for(int i=0;i (less than) cookLength;i++) {
            initialState.addCookie(cookies[i]);
        }
        client.setState(initialState);


        try {
            status = client.executeMethod(post);

        System.out.println("response code = "+status);

        byte[] buf = new byte[10];
        int r=0;
        BufferedInputStream is = new BufferedInputStream(post.getResponseBodyAsStream());

        while((r = is.read(buf)) > 0) {
            System.out.write(buf, 0, r);
        }
        post.releaseConnection();
        } catch(IOException ex) {
            ex.printStackTrace();
        }
    }

And I have this:

400 Error: Bad Request

Missing or invalid form token. Do you have cookies enabled?

What’s wrong?

trac_form_token=e9648f17987551b8f97e1953

Probably I nedd change this:

client.getParams().setCookiePolicy(CookiePolicy.BROWSER_COMPATIBILITY);
