    Python3 如何开启自带http服务

    作者:HanZhizhi 时间:2021-06-04 17:44

    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()
    

    打包exe

    pip install pyinstaller

    pyinstaller -F xxx.py 即可,当前目录下生成

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

    当时自己建了一个py叫http,删掉后正常

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

    另存为utf-8即可

    以上为个人经验,希望能给大家一个参考,也希望大家多多支持站长博客。
