我在亚马逊上托管了Ejabberd聊天服务器，并在那里添加了两个用户，当我尝试通过Adium连接Ejabberd服务器时，它要求提供证书然后才连接，现在我正在开发聊天使用Ejabberd服务器和XMPP在Swift中的应用程序，我配置了所有代码，传递了主机名和端口号：5222，但它没有连接到服务器。
我是否需要编写程序来获取服务器证书并将我的计算机证书（.p12）文件传递给服务器？
注意：我在localhost和iOS Swift Code中配置了Ejabberd服务器，当我从iOS应用程序发送消息然后它在Adium中显示，当Adium用户发送消息然后我去Ejabberd时，它工作正常Web管理员面板，可以离线检查消息。
以下是Swift中用于连接在亚马逊上托管的Ejabberd的代码：

func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.

答案 0 :(得分：0)
最后，我设法解决了这个问题，使用亚马逊上托管的Ejabberd服务器实现聊天应用程序真的很让人惊讶。
问题：
1。当我运行我的应用程序时，它没有连接？
答案：证书问题（服务器 - 客户端证书握手解决问题）
2。无法获取在线好友？ 答：我使用Adium让所有用户在线，然后运行我的应用程序，它就像一个魅力。
对于这个应用程序我很好的学习。 如果any1有任何聊天问题，请随时发表评论我期待着提供帮助。感谢
