如何使用Smack在XMPP服务器中按名称搜索注册用户？

Question

我正在使用asmack库开发Android中的聊天应用程序.我正在使用EJABBERD XMPP服务器.我已经完成了一些功能,包括登录,注册和名册条目等,

现在我想从XMPP服务器搜索注册用户发送好友请求.我用Google搜索并尝试了一些代码,但仍未获得成功.

我正在使用以下代码从XMPP服务器搜索用户.

UserSearchManager userSearchManager = new UserSearchManager(connection);
Form searchForm = userSearchManager.getSearchForm("search." + connection.getServiceName());
Form answerForm = searchForm.createAnswerForm();
answerForm.setAnswer("Name", true);
answerForm.setAnswer("search", "test"); // here i'm passsing the Text value to search

ReportedData resultData;
resultData = userSearchManager.getSearchResults(answerForm, "search."+ connection.getServiceName());

Iterator<Row> it = resultData.getRows();
Row row = null;
while (it.hasNext()) {
    String value = it.next().toString();
    Log.i("Iteartor values......", " " + value);
    System.out.println("Jabber_id :" + row.getValues("jid").next().toString());
    System.out.println("Name :" + row.getValues("Name").next().toString());
    row = it.next();
}

当我执行上面的代码.我在LogCat中收到以下错误.

service-unavailable(503)

    at org.jivesoftware.smackx.search.UserSearch.getSearchForm(UserSearch.java:84)

    at org.jivesoftware.smackx.search.UserSearchManager.getSearchForm(UserSearchManager.java:73)

要获得搜索结果需要进行哪些更改？

由于ejabberd的默认配置是保持搜索服务vjud.example.com,不是search.example.com,您需要更改此行:

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

对此:

Form searchForm = userSearchManager.getSearchForm("vjud." + connection.getServiceName());
