    <p>I would like to generate POST request to a server which requires authentication. I tried to use the following method:</p> <pre><code>private synchronized String CreateNewProductPOST (String urlString, String encodedString, String title, String content, Double price, String tags) { String data = "product[title]=" + URLEncoder.encode(title) + "&amp;product[content]=" + URLEncoder.encode(content) + "&amp;product[price]=" + URLEncoder.encode(price.toString()) + "&amp;tags=" + tags; try { URL url = new URL(urlString); URLConnection conn; conn = url.openConnection(); conn.setRequestProperty ("Authorization", "Basic " + encodedString); conn.setDoOutput(true); conn.setDoInput(true); OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream()); wr.write(data); wr.flush(); // Get the response BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); String line; while ((line = rd.readLine()) != null) { // Process line... } wr.close(); rd.close(); return rd.toString(); } catch (MalformedURLException e) { e.printStackTrace(); return e.getMessage(); } catch (IOException e) { e.printStackTrace(); return e.getMessage(); } } </code></pre> <p>but the server doesn't receive the authorization data. The line which is supposed to add authorization data is the following:</p> <pre><code>conn.setRequestProperty ("Authorization", "Basic " + encodedString); </code></pre> <p>and the line </p> <pre><code>BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream())); </code></pre> <p>also throws an IOException.</p> <p>Anyway I would be very thankful if anyone could suggest any fix of the logic above in order to enable authorization using POST with UrlConnection.</p> <p>but obviously it doesn't work as it is supposed to although if the same logic is used for GET request everything works fine.</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.
