Nginx supports SNI certificate, which has been used by ssl_server_name

I have compiled some information online and recorded it here for your reference What is SNI? In traditional application scenarios, a server corresponds to an IP address and a domain name, using a certificate containing domain name information. With the popularization of cloud computing technology, the virtual machine in the cloud has an IP, corresponds […]

stm32 serial port sends data packets for analysis to achieve human-computer interaction

Serial port sending and receiving parsing data packets Students who have studied stm32 know that it is very convenient to use the serial port to communicate with 32. In the official process of punctual atoms, we can see that in the serial port interrupt service function, a sixteen-bit data is used for the received data. […]
