  1. POHandling non ASCII characters with principals in CQ5 REST interface
    text
    copied!<p>We are managing CQ5 groups using the REST interface. To add a user we do</p> <pre><code>POST http://$host:$port/home/groups/t/test_group.rw.html Content-Type: application/x-www-form-urlencoded addMembers:my_principal_name </code></pre> <p>which works as expected as long as the the name contains ASCII characters only.</p> <p>We tried to use latin 1 (ISO-8859-1). For example for a principal name <code>ü</code>:</p> <pre><code>POST http://$host:$port/home/groups/t/test_group.rw.html Content-Type: application/x-www-form-urlencoded addMembers:%FC </code></pre> <p>In this case no error is generated but the principal is not added.</p> <p>Our workaround is to use UTF-8 and URL-encode it <strong>twice</strong>. <code>ü</code> is <code>C3BC</code>, URL-encoded it becomes <code>%C3%BC</code> and encoded another time <code>%25C3%25BC</code></p> <p>Summarizing, to add a member <code>ü</code> we have to submit</p> <pre><code>POST http://$host:$port/home/groups/t/test_group.rw.html Content-Type: application/x-www-form-urlencoded addMembers:%25C3%25BC </code></pre> <p>which works as expected.</p> <p>Is this a bug or the API really requires to send UTF-8-encoded strings URL encoded twice?</p> <p><strong>Edit</strong> I tried with the additional <code>_charset_</code> parameter</p> <pre><code>telnet ******** 8000 Trying ********...
