使用 asmack 连接服务器时出现 SSL 异常答案

【问题标题】：SSL Exception on Connecting to Server using asmack使用 asmack 连接服务器时出现 SSL 异常
【发布时间】：2015-03-19 11:34:14
【问题描述】：

我正在为我的聊天应用程序使用 asmack-android-16。有时，在创建连接时，我遇到 SSL 异常，然后我无法登录服务器。我的服务器正在使用 SSL 身份验证进行连接。有人可以帮帮我吗？几周以来我一直在努力解决这个问题

这是我的连接配置：

    HOST = "my_ejabbered_url";
    PORT = "5223";
    connectionConfiguration = new ConnectionConfiguration(HOST,PORT);
    connectionConfiguration.setDebuggerEnabled(true);
    SASLAuthentication.supportSASLMechanism("PLAIN");
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
        connectionConfiguration.setTruststoreType("AndroidCAStore");
        connectionConfiguration.setTruststorePassword(null);
        connectionConfiguration.setTruststorePath(null);
    } else {
        connectionConfiguration.setTruststoreType("BKS");
        String path = System.getProperty("javax.net.ssl.trustStore");
        if (path == null)
            path = System.getProperty("java.home") + File.separator + "etc"
                    + File.separator + "security" + File.separator
                    + "cacerts.bks";
        connectionConfiguration.setTruststorePath(path);
    }
    connectionConfiguration.setSASLAuthenticationEnabled(true);

XMPPConnection 连接 = 新 XMPPConnection(connectionConfiguration); 连接.连接（）； // 尽管创建了连接，但调用此行给了我异常。

以下是日志：

【解决方案1】：

您的日志中有一些奇怪的东西：

您正在使用端口 5223，通常是 SSL
您的会话表明您正在尝试使用 starttls。

我本来希望是其中之一。

您是否尝试过使用端口 5222？

【讨论】：

我的服务器需要 tls 身份验证。那么，如果我将端口更改为 5222，这是否会使我的身份验证保持为 tls？
5222 可以配置为 starttls，这意味着您的客户端将在连接时协商加密。看起来这是您的客户尝试做的事情（请参阅日志中的 startls）。参考：xmpp.org/rfcs/rfc6120.html#tls
端口 5222 不起作用。您对进一步调查有何建议，因为这已成为我的应用程序的严重问题。
该配置似乎适用于 android 5.0.1 及更高版本。问题出在密钥库中。收到错误提示“未找到密钥库 jks 实现”
