[英]SSL_do_handshake() get stuck
in my code i call SSL_do_handshake() function. 在我的代码中,我调用SSL_do_handshake()函数。 Everything works fine if the server gets the "right" messages.
如果服务器收到“正确的”消息,一切正常。 BUT, for security issues I tried sending a dummy message.
但是,出于安全性问题,我尝试发送虚拟消息。 just "hello" to the right port and the right ip address.
只是“ hello”到正确的端口和正确的ip地址。 in this case, SSL_do_handshake() gets stuck forever.
在这种情况下,SSL_do_handshake()会永远卡住。 I want the function to return in that case, so that my server will not get stuck.
在这种情况下,我希望函数返回,这样我的服务器就不会卡住。
What are the options ? 有什么选择 ?
I read about setting bio to non-blocking.. I added to my code : BIO_set_nbio(bio, 1); 我阅读了有关将bio设置为非阻塞的信息。我在代码中添加了:BIO_set_nbio(bio,1); before the connection is established.. but it didn't do thew work...
在建立连接之前..但是它没有做...
What can I do ? 我能做什么 ?
BIO_set_nbio sets only the flag, that the bio should be considered non-blocking. BIO_set_nbio仅设置标志,即应将bio视为非阻塞标志。 You have to actually make the socket itself non-blocking.
您实际上必须使套接字本身无阻塞。
