Python3 如何开启自带http服务_Python

开启Web服务

1.基本方式

Python中自带了简单的服务器程序，能较容易地打开服务。

在python3中将原来的SimpleHTTPServer命令改为了http.server，使用方法如下：

1. cd www目录

2. python -m http.server

开启成功，则会输出“Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) …”，表示在本机8000端口开启了服务。

如果需要后台运行，可在命令后加"&"符号，Ctrl+C不会关闭服务，如下：

				?

									python -m http.server &

如果要保持服务，则在命令前加nohup以忽略所有挂断信号，如下：

				?

									nohup python -m http.server 8001

2.指定端口

如果不使用默认端口，可在开启时附带端口参数，如：

				?

									python -m http.server 8001

则会在8001端口打开http服务。

使用Web服务

可以使用http://0.0.0.0:8000/查看www目录下的网页文件，若无index.html则会显示目录下的文件。

也可以使用ifconfig命令查看本机IP并使用。

补充：python创建http服务

背景

用java调用dll的时候经常出现 invalid memory access，改用java-Python-dll，

Python通过http服务给java提供功能。

环境

Python3.7

通过 http.server.BaseHTTPRequestHandler 来处理请求，并返回response

打印日志

filename为输入日志名称，默认是同目录下，没有该文件会新创建

filemode a 是追加写的模式，w是覆盖写

				?

									import logging

									logging.basicConfig(

									    level=logging.INFO,

									    format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',

									    filename="hhh.txt",

									    filemode='a'

									)

									logging.info("xxxx")

调用dll

pchar - ctypes.c_char_p

integer 用了 bytes(0)，byref(ctypes.c_void_p(0)) 都OK，没有更深入去研究，如有错误请指正。

				?

									import ctypes

									from ctypes import *

									dll = ctypes.windll.LoadLibrary('C:\\xxx\\xxx.dll')

									print("dll版本号为 ： "+ str(dll.GetVersion()) )

									 name = ctypes.c_char_p(b"gc")

									            roomno = ctypes.c_char_p(bytes(room.encode("utf-8")))

									            begintime = ctypes.c_char_p(bytes(begin.encode("utf-8")))

									            endtime = ctypes.c_char_p(bytes(end.encode("utf-8")))

									            cardno = ctypes.c_void_p(0)

									            dll.invoke...

http方案一

要注意必须有 response = response_start_line + response_headers + “\r\n” + response_body

拼接应答报文后，才能给浏览器正确返回

				?

									# coding:utf-8

									import socket

									from multiprocessing import Process

									def handle_client(client_socket):

									    # 获取客户端请求数据

									    request_data = client_socket.recv(1024)

									    print("request:", request_data)

									    # 构造响应数据

									    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)

									    # 向客户端返回响应数据

									    client_socket.send(bytes(response, "utf-8"))

									    # 关闭客户端连接

									    client_socket.close()

									if __name__ == "__main__":

									    server_socket = socket.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]用户连接上了" % client_address)

									        handle_client_process = Process(target=handle_client, args=(client_socket,))

									        handle_client_process.start()

									        client_socket.close()

另外一种http方式

				?

									#-.- coding:utf-8 -.-

									from http.server import  HTTPServer

									import ctypes

									from ctypes import *

									# HTTPRequestHandler class

									import http.server

									import socketserver

									import logging

									# pyinstaller -F

									class testHTTPServer_RequestHandler(http.server.BaseHTTPRequestHandler):

									    # GET

									  def do_GET(self):

									        logging.error('start make ')

									        str2 =  str(self.path)

									        print("revice： " + str2)

									        if "xxx" in str2:

									            # todo 你的具体业务操作

									            if "xxx" in str2:

									                print("hahaha")

									                logging.error('hahaha')

									                # response_body = "0"

									                self.send_response(200)

									                # Send headers

									                self.send_header('Content-type','text/html')

									                self.end_headers()

									                # Send message back to client

									                message = "Hello world!"

									                # Write content as utf-8 data

									                self.wfile.write(bytes(message, "utf8"))

									                return

									        else:

									            print("1else")

									            self.send_response(200)

									            # Send headers

									            self.send_header('Content-type', 'text/html')

									            self.end_headers()

									            # Send message back to client

									            message = "Hello world222333!"

									            # Write content as utf-8 data

									            self.wfile.write(bytes(message, "utf8"))

									            return

									def run():

									  print('starting server...')

									  logging.basicConfig(

									      level=logging.INFO,

									      format='%(asctime)s %(filename)s[line:%(lineno)d] %(levelname)s %(message)s',

									      filename="http_make_card.txt",

									      filemode='a+'

									  )

									  # Server settings

									  server_address = ('127.0.0.1', 8888)

									  httpd = HTTPServer(server_address, testHTTPServer_RequestHandler)

									  print('running server...')

									  httpd.serve_forever()

									run()
