标题是我的问题。Boost Asio如何读取/写入不使用SSL的SSL套接字?
我已经发现了与此相关的话题在这里 - >Using SSL sockets and non-SSL sockets simultaneously in Boost.Asio?
,基本上我在同样的情况,但由于某种原因,我不能发表评论,有和/或咨询提问直接,所以我这样做作为一个新问题。
我有一个设置SSL插座ssl::stream<ip::tcp::socket> socket_;
,在这里客户可以与
socket_.async_handshake(ssl::stream_base::server, session::handle_handshake)
连接就好了,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)
但是现在写我想使用相同类型的插座建立不使用SSL的连接。所有的
首先我不确定该怎么办了“握手”,因为它与SSL连接正如我上面提到完成。
通过查看一些正常的boost.asio示例,我假设我不需要为非ssl连接执行此操作,并且只需在它被接受后直接读取/写入套接字?
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,我加了一个布尔SSL会话,以检查其是否SSL连接或没有。
然后,我使用socket_.lowest_layer()
而不是在异步函数中使用socket_
。
这里的推荐代码:
if (sslEnabled)
boost::asio::async_write(secureSocket_);
} else {
boost::asio::async_write(secureSocket_.lowest_layer());
}
但是似乎编译犯规接受这个解决方案。当我尝试使用具有socket_.lowest_layer()作为流这个错误显示了一个异步函数编译代码(其只对async_read,ASYNC_WRITE也有类似的一个):

Build FAILED.
所以我现在几乎卡住了,我真的希望你能帮助我。搜索带来的误差高达不信邪,因为按理说应该有工作,我不知道这个错误可能是什么...
