问题描述

我正在使用 asmack 库在 Android 中开发聊天应用程序.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，

I'm working on developing chat application in Android with asmack library. I'm using EJABBERD XMPP server. I have done some functionality including login, registration and roster entries etc.,

现在我想从 XMPP 服务器搜索注册用户以发送好友请求.我用谷歌搜索并尝试了一些代码，但仍然没有成功.

Now i want to search Registered users from XMPP server to send Buddy request. I googled and tried some codes but still not get succeed.

我正在使用以下代码从 XMPP 服务器搜索用户.

I'm using the following code, to Search the user from XMPP server.

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();
}

当我执行上述代码时.我在 LogCat 中收到以下错误.

When i execute the above Code. I'm getting the following error in LogCat.

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

需要进行哪些更改才能获得搜索结果?

推荐答案

由于 ejabberd 的默认配置是将搜索服务保留在 vjud.example.com 上，而不是 search.example.com，您需要更改此行:

As the default configuration of ejabberd is to keep the search service on vjud.example.com, not search.example.com, you'd need to change this line:

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

到此:

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