    <p>I'm trying to use the Reddit API to do some stuff. I have everything working but changing pages and logging in.</p> <p>I need to login to use my program, I know how to use the cookie I get, but I just can't manage to login.</p> <p>Here's the code:</p> <pre><code>public static Login POST(URL url, String user, String pw) throws IOException { String encodedData = URLEncoder.encode("api_type=json&amp;user=" + user +"&amp;passwd="+pw, "UTF-8"); HttpURLConnection ycConnection = null; ycConnection = (HttpURLConnection) url.openConnection(); ycConnection.setRequestMethod("POST"); ycConnection.setDoOutput(true); ycConnection.setUseCaches (false); ycConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded; charset=UTF-8"); PrintWriter out = new PrintWriter(ycConnection.getOutputStream()); out.print(encodedData.getBytes()); out.close(); BufferedReader in = new BufferedReader(new InputStreamReader(ycConnection.getInputStream())); String response = in.readLine(); Map&lt;String, List&lt;String&gt;&gt; headers = ycConnection.getHeaderFields(); List&lt;String&gt; values = headers.get("Set-Cookie"); String cookieValue = null; for (java.util.Iterator&lt;String&gt; iter = values.iterator(); iter.hasNext(); ) { String v = iter.next(); if (cookieValue == null) cookieValue = v; else cookieValue = cookieValue + ";" + v; } return new Login(cookieValue, response); } </code></pre> <p>The most typical exception I get is:</p> <blockquote> <p>java.io.IOException: Server returned HTTP response code: 504 for URL: <a href="http://www.reddit.com/api/login/kagnito/" rel="noreferrer">http://www.reddit.com/api/login/kagnito/</a> at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source)</p> </blockquote> <p>But I have also received a lot of "invalid password" messages.</p> <p>How might I resolve this? Been at it for hours!</p> <p>Btw. This is what I'm having trouble understanding: <a href="https://github.com/reddit/reddit/wiki/API%3A-login" rel="noreferrer">https://github.com/reddit/reddit/wiki/API%3A-login</a> I'm not sure how to POST this? Should it go into the header, or ? I'm not that familiar with the HTTP protocol. (Hence my project - I'm learning)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
