升压短耳如何阅读，这并不使用SSL一个SSL插座/写？ [英] Boost Asio how to read/write on a SSL socket that doesnt use SSL?
问题描述
标题是我的问题。
我已经找到与此相关的这里主题 - > <一个href=\"http://stackoverflow.com/questions/4720120/using-ssl-sockets-and-non-ssl-sockets-simultaneously-in-boost-asio\">Using SSL套接字和非SSL套接字同时在Boost.Asio的？结果
基本上我在同样的情况，但由于某种原因，我不能有意见和/或直接接触，所以我这样做，作为一个新的问题提问。
I already found a topic related to this here -> Using SSL sockets and non-SSL sockets simultaneously in Boost.Asio?
and basically I'm in the same situation but for some reason I couldn't comment there and/or contact the questioner directly so I'm doing this as a new question.
我有一个设置SSL插座 SSL ::流＆LT; IP :: TCP ::插座＆GT;插座_; ，其中客户端可以与连接就好了。
I have a set up ssl socket ssl::stream<ip::tcp::socket> socket_; where clients can connect just fine with
socket_.async_handshake(ssl::stream_base::server, session::handle_handshake)
，然后读/
async_write(socket_, buffer(send_data, send_length), session::handle_read)
socket_.async_read_some(buffer(recieved_data, max_length), session::handle_read)
但现在我想使用相同类型的插槽，建立了不使用SSL连接。
However now I want to use the same type of socket to build up connections that dont use SSL.
所有我不确定该怎么做了握手，因为它是用SSL连接正如我上面提到做的第一。结果通过查看一些正常的Boost.Asio的例子，我认为我没有这样做，对于非SSL连接，只需直接一旦被接受读/写的socket？
First of all I'm unsure how to do the "handshaking" as it is done with a SSL connection as I mentioned above.
By looking at some normal boost.asio example I assume that I dont have to do that for non-ssl connections and just directly read/write to the socket once it has been accepted?
然后作为下一步我试图做到这一点正如我上面提到的话题decsribed，我添加了一个布尔SSL会话，检查其是否SSL连接或没有。结果这时，而不是使用插座_ 中的异步功能，我使用了 socket_.lowest_layer（）。
Then as a next step I tried to do it as decsribed in the topic I mentioned above, I added a boolean ssl to session to check whether its a SSL connection or not.
Then instead of using socket_ in the async functions, I used socket_.lowest_layer().
下面是建议code：
if ( sslEnabled )
boost::asio::async_write( secureSocket_ );
} else {
boost::asio::async_write( secureSocket_.lowest_layer() );
}
但是它似乎是编译犯规接受该溶液中。当我尝试编译code与具有socket_.lowest_layer（）作为流这个错误显示了一个异步函数（其只对async_read，async_write也有类似的一个）：
However it seems that the compiler doesnt accept this solution. When I try to compile the code with an async function that has socket_.lowest_layer() as a stream this error shows up (its only for async_read, async_write has a similar one):

Build FAILED.
所以我现在pretty多卡住，我真的希望你能帮助我。搜索错误长大不信邪，因为它应该按说工作，我不知道这个错误可能是什么...
So now I'm pretty much stuck and I really hope you can help me. Searching for the error brought up nothing and since it should supposedly work I dont know what the mistake could be...
推荐答案
其实我觉得我现在解决了。
Actually I think I solved it now.
1）非SSL的握手的确是没有必要的，我马上做async_reading后接受
1) The "handshaking" on a non-ssl is indeed not necessary, I immediately do async_reading after the accept
2），而不是 async_read /写（socket_.lowest_layer（），...）我不得不使用 socket_.next_layer（）。 async_read_some（缓冲，处理器）和结果 async_write（socket_.next_layer（），...）
2) Instead of async_read/write( socket_.lowest_layer(), ... ) I had to use socket_.next_layer().async_read_some( buffer, handler) and
async_write( socket_.next_layer(), ... )
我仍然不知道为什么它不与socket_.lowest_layer工作（）（如果有人知道，请解释），但至少它的工作原理只是上述方法的罚款。我希望这将帮助其他人有类似的问题太多; - ）
I still dont know why it doesnt work with socket_.lowest_layer() (if someone knows, please explain) but at least it works just fine with the above methods. And I hope this will help other people with a similar problem too ;-)
