Today, the editor will share with you the relevant knowledge points about how to quickly establish web services in python. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

1. Description

(1) sometimes we need a simple and quick way to build RPC services. Just let program B call program A.

(2) you don't need to know any technology about this, but we only need something so simple. We can use a protocol (the corresponding Python library implementation SimpleXMLRPCServer) to handle this kind of thing.

2. Instance from SimpleXMLRPCServer import SimpleXMLRPCServer def file_reader (file_name): with open (file_name,'r') as f: return f.read () server = SimpleXMLRPCServer (('localhost', 8000)) server.register_introspection_functions () server.register_function (file_reader) server.serve_forever ()

Instance expansion:

Python implements a simple web server

Import reimport socket def service_cilent (new_socket): request = new_socket.recv (1024). Decode ("utf-8") # Python splitlines () separated by line (',',') returns a list of lines as elements, if the parameter keepends is False and does not contain newline characters, if True, the newline character is retained. Request_lines = request.splitlines () print (request_lines) file_name = "" ret = re.match (r "[^ /] + (/ [^] *)", request_lines [0]) if ret: file_name = ret.group (1) if file_name = = "/": file_name = "index.html" try: F = open (file_name "rb") except: response = "HTTP/1.1 404 NOT FOUND" response + = "- file not found-" new_socket.send (response.encode ("utf-8")) else: # Open the file successfully read the file and then close the file pointer html_content = f.read () f.close () # data to be sent to the browser -header response = "HTTP/1.1 200 OK" # send response header to browser new_socket.send (response.encode ("utf-8")) # send response body to browser new_socket.send (html_content) # close socket new_socket.close () def main (): # create socket tcp_server_socket = socket.socket (socket.AF_INET Socket.SOCK_STREAM) # tcp_server_socket.setsockopt (socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) # bind tcp_server_socket.bind ((", 7089)) # listening socket tcp_server_socket.listen (128C) while True: new_socket Cilent_addr = tcp_server_socket.accept () service_cilent (new_socket) # turn off the listening socket tcp_server_socket.close () if _ _ name__ ='_ _ main__': main () these are all the contents of the article "how to quickly set up web Services in python" Thank you for reading!
