Java Netty 未知 SSL 内容类型错误
Java Netty Unknown SSL content type error
我正在尝试使用 Netty 5.0.0.Alpha2 编写一个 HTTP 客户端来连接到专有服务器。我只能将连接描述为类似于 Websockets 但不是。服务器使用 StartTLS,它预计在服务器以 200 和内容类型响应后由客户端初始化,如果您不这样做,服务器将断开您的连接。一旦连接安全,服务器将在响应客户端命令时无限期地保持连接。无论如何,下面是我的 SSLDump 日志和关于行 "Unknown SSL content type 1",一旦我尝试将我的第一个命令发送到服务器,就会发生这种情况。来自服务器的流量似乎不受阻碍,因为服务器每 30-60 秒发送一次 ping 心跳,我可以很好地读取它。

有人可以向我解释为什么会出现此错误以及我可以采取什么措施来补救吗?我一开始以为是我用来写数据的对象类型,即ByteBuf,但是我尝试了很多其他对象,它似乎没有效果。我确定有一个明显的原因,我只是没有看到它。我对将 SSL 与 Netty 结合使用还很陌生,遗憾的是我找不到足够多的文档,因为我认为 Netty 会像现在这样被广泛使用。
如果有人能提供任何帮助,我将不胜感激。
编辑:
有趣的是,使用服务器(还有 Netty 和 Java)我使用相同的 SSL 引擎编程声称它也可以建立连接但是它应该接收我的命令,它会打印此错误。这会让我相信我的客户端没有正确编码 ssl 数据包,因为它报告的记录是纯文本的。

看来我是个彻头彻尾的白痴。就像我说的,我不熟悉将 SSL 与 Netty 结合使用。
原来在我的代码中,在我的 SslHandler() 构造函数下,还有一个名为 startTLS 的可选布尔值。如果设置为 True,SslHandler 将以明文形式输出您的第一条消息。我对说 StartTLS is the communication pattern that secures the wire in the middle of the plaintext connection. Please note that it is different from SSL/TLS, that secures the wire from the beginning of the connection.
的 javadoc 感到困惑,因为我在发送 HTTP headers 后启动 SSL,所以我认为 StartTLS 是我想要的。
同样,我对找不到的 Netty 文档感到失望。这个愚蠢的问题现在已经解决,我感到很欣慰,我可以继续对该网络协议进行逆向工程。
我正在尝试使用 Netty 5.0.0.Alpha2 编写一个 HTTP 客户端来连接到专有服务器。我只能将连接描述为类似于 Websockets 但不是。服务器使用 StartTLS,它预计在服务器以 200 和内容类型响应后由客户端初始化,如果您不这样做,服务器将断开您的连接。一旦连接安全,服务器将在响应客户端命令时无限期地保持连接。无论如何,下面是我的 SSLDump 日志和关于行 "Unknown SSL content type 1",一旦我尝试将我的第一个命令发送到服务器,就会发生这种情况。来自服务器的流量似乎不受阻碍,因为服务器每 30-60 秒发送一次 ping 心跳,我可以很好地读取它。

有人可以向我解释为什么会出现此错误以及我可以采取什么措施来补救吗?我一开始以为是我用来写数据的对象类型,即ByteBuf,但是我尝试了很多其他对象,它似乎没有效果。我确定有一个明显的原因,我只是没有看到它。我对将 SSL 与 Netty 结合使用还很陌生,遗憾的是我找不到足够多的文档,因为我认为 Netty 会像现在这样被广泛使用。
如果有人能提供任何帮助,我将不胜感激。
编辑:
有趣的是,使用服务器(还有 Netty 和 Java)我使用相同的 SSL 引擎编程声称它也可以建立连接但是它应该接收我的命令,它会打印此错误。这会让我相信我的客户端没有正确编码 ssl 数据包,因为它报告的记录是纯文本的。

看来我是个彻头彻尾的白痴。就像我说的,我不熟悉将 SSL 与 Netty 结合使用。
原来在我的代码中,在我的 SslHandler() 构造函数下,还有一个名为 startTLS 的可选布尔值。如果设置为 True,SslHandler 将以明文形式输出您的第一条消息。我对说 StartTLS is the communication pattern that secures the wire in the middle of the plaintext connection. Please note that it is different from SSL/TLS, that secures the wire from the beginning of the connection.
的 javadoc 感到困惑,因为我在发送 HTTP headers 后启动 SSL,所以我认为 StartTLS 是我想要的。
同样,我对找不到的 Netty 文档感到失望。这个愚蠢的问题现在已经解决,我感到很欣慰,我可以继续对该网络协议进行逆向工程。
