使用 (a)smack 检查 XMPP 中的服务器上是否存在用户 [英] Check if a user exist on server in XMPP with (a)smack

问题描述

我正在使用 asmack 作为库并在 android 平台上开发聊天应用程序.有什么办法可以在添加好友之前先查看服务器上是否存在该好友?

I'm working on a chat application using asmack as a library and on android platform. Is there is any way that before adding friend in Roster can I check that friend exist on server or not?

推荐答案

我找到了答案:

UserSearchManager search = new UserSearchManager(mXMPPConnection);
Form searchForm = search
    .getSearchForm("search." + mXMPPConnection.getServiceName());

Form answerForm = searchForm.createAnswerForm();
answerForm.setAnswer("Username", true);
answerForm.setAnswer("search", user);
ReportedData data = search
    .getSearchResults(answerForm, "search." + mXMPPConnection.getServiceName());

if (data.getRows() != null) {
    for (ReportedData.Row row: data.getRows()) {
        for (String value: row.getValues("jid")) {
            Log.i("Iteartor values......", " " + value);
        }
    }
    Toast.makeText(_service, "Username Exists", Toast.LENGTH_SHORT).show();
}

如果服务器没有任何指定名称的输入，则 Itearator 它没有值并且代码不会进入 while(it.hasNext)..

if Server has not any entery with that specified name then Itearator it has no value and code will not go inside while(it.hasNext)..
