在openfire中搜索用户时出现错误请求400

我试图在明火中搜索用户 .

public void searchUser(String username) {
        UserSearchManager userSearchManager = new UserSearchManager(
                xmppConnection);
        Form searchForm;
        try {

            searchForm = userSearchManager.getSearchForm("search."
                    + xmppConnection.getServiceName());

            Form answerForm = searchForm.createAnswerForm();
            answerForm.setAnswer("Username", true);

            answerForm.setAnswer("search", username);

            org.jivesoftware.smackx.ReportedData data = userSearchManager
                    .getSearchResults(answerForm,
                            "search." + xmppConnection.getServiceName());

            if (data.getRows() != null) {
                Iterator<Row> it = data.getRows();
                while (it.hasNext()) {
                    Row row = it.next();
                    Iterator<?> iterator = row.getValues("jid");
                    if (iterator.hasNext()) {
                        String value = iterator.next().toString();
                        System.out.println(value);
                    }

                }

            }
        } catch (XMPPException e) {
            e.printStackTrace();
        }
    }

有一些类似的线程所以我跟着他们并在连接之前添加了这个提供者管理器 .
