Python3 how to turn on its own http service

Enabling Web Services

1. Basic approach

Python comes with a simple server program that makes it easier to open services.

The original SimpleHTTPServer command has been changed in python3 to use the following:

1. cd www directory

2. python -m

If it is successfully opened, the output will be "Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...", indicating that the service is opened on port 8000 of the local machine.

If you need to run in the background, you can add the "&" symbol after the command, and Ctrl+C will not close the service, as follows:

python -m  &

If you want to keep the service, prefix the command with nohup to ignore all hangup signals, as follows:

nohup python -m  8001

2. Specify the port

If the default port is not used, it can be turned on with a port parameter such as:

python -m  8001

Then the http service will be opened on port 8001.

Using Web Services

You can use http://0.0.0.0:8000/ferret outwwwWeb files in the directory, if not it will show the files in the directory.

You can also use the ifconfig command to view the local IP and use it.

Addendum: python create http service

contexts

Invalid memory access often occurs when calling dlls with java, use java-Python-dll instead.

Python provides functionality to java via http services.

Python3.7

to process the request and return a response.

Print Log

filename is the name of the input log, the default is the same directory, without the file will create a new

filemode a is the append mode, w is the overwrite mode

import logging
(
    level=,
    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',
    filename="",
    filemode='a'
)
("xxxx")

Calling the dll

pchar - ctypes.c_char_p

integer used bytes(0), byref(ctypes.c_void_p(0)) are OK, did not go more in-depth study, if there is any error, please correct me.

import ctypes
from ctypes import *
dll = ('C:\\xxx\\')
print("The dll version number is: "+ str(()) )
 name = ctypes.c_char_p(b"gc")
            roomno = ctypes.c_char_p(bytes(("utf-8")))
            begintime = ctypes.c_char_p(bytes(("utf-8")))
            endtime = ctypes.c_char_p(bytes(("utf-8")))
            cardno = ctypes.c_void_p(0)
            ...

http Program I

Be aware that you must have response = response_start_line + response_headers + "\r\n" + response_body

Splicing the answer message is required to return the correct answer to the browser.

# coding:utf-8
import socket
from multiprocessing import Process
def handle_client(client_socket):
    # Get client request data
    request_data = client_socket.recv(1024)
    print("request:", request_data)
    # Construct response data
    response_start_line = "HTTP/1.1 200 OK\r\n"
    response_headers = "Server: My server\r\n"
    response_body = "helloWorld!"
    response = response_start_line + response_headers + "\r\n" + response_body
    print("response:", response)
    # Return response data to the client
    client_socket.send(bytes(response, "utf-8"))
    # Close the client connection
    client_socket.close()
if __name__ == "__main__":
    server_socket = (socket.AF_INET, socket.SOCK_STREAM)
    server_socket.bind(("", 8888))
    server_socket.listen(120)
    print("success")
    while True:
        client_socket, client_address = server_socket.accept()
        print("[%s, %s] user is connected." % client_address)
        handle_client_process = Process(target=handle_client, args=(client_socket,))
        handle_client_process.start()
        client_socket.close()

Packaging exe

pip install pyinstaller

pyinstaller -F will do the trick, and the current directory will generate the

defraud

1、No module named ‘'; ‘http' is not a package

At that time, I built a py called http myself, and deleted it as normal

2、UnicodeDecodeError: ‘utf-8' codec can't decode byte 0xce in position 130: invalid continuat

Just save as utf-8

The above is a personal experience, I hope it can give you a reference, and I hope you can support me more.
