如何选择协议？
因此，我制作了将图片发送给客户端的服务器。但是，当扣除数据包时，我看到数据包的协议是http。为什么是HTTP，但没有其他？
import socket
file_to_return = open(r"C:\Users\hadad\Desktop\webroot\imgs\abstract.jpg", 'rb')
file_content = file_to_return.read()
server_socket = socket.socket()
server_socket.bind(("0.0.0.0", 80))
server_socket.listen()
client_socket, client_address = server_socket.accept()
client_socket.send(file_content)
so I have made server which sends a picture to client. but when snaffing the packets I see that the protocol of the packet is HTTP. why would it be HTTP but no other?
import socket
file_to_return = open(r"C:\Users\hadad\Desktop\webroot\imgs\abstract.jpg", 'rb')
file_content = file_to_return.read()
server_socket = socket.socket()
server_socket.bind(("0.0.0.0", 80))
server_socket.listen()
client_socket, client_address = server_socket.accept()
client_socket.send(file_content)

端口80通常是HTTP服务的端口。但是，没有什么可以阻止某人在80港口上忽略惯例并运行完全不同的服务 /协议。
当然，这样做这种事情的人有可能为自己造成麻烦和对他人烦恼。
协议映射的标准端口＃由IANA定义：
在典型的linux/unix系统上，标准端口分配也列在
/etc/code>文件中。因为明智人们遵循惯例。
Port 80 is conventionally the port for an HTTP service. But nothing stops someone from ignoring the conventions and running a completely different service / protocol on port 80.
Of course, people who do that kind of thing are liable to cause trouble for themselves and annoyance for other people.
The standard port # to protocol mappings are defined by IANA:
On a typical Linux / UNIX system, the standard port assignments are also listed in the
/etc/servicesfile.Because sensible people follow the conventions.
