python高级学习笔记Day02--python静态Web服务器的搭建 开发自己静态Web服务器

pycharm打开包含服务器资源（html文件，图片资源等）的文件夹，创建新py文件

代码如下：

 import socket

if __name__ == '__main__':
    tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcp_server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True)
    tcp_server_socket.bind(('', 8080))
    tcp_server_socket.listen(128)
    while True:
        client_socket, client_ip = tcp_server_socket.accept()
        client_request_data = client_socket.recv(1024).decode()
        print(client_request_data)
        with open('./index.html', 'rb') as fp:
            file_data = fp.read()
        response_line = 'HTTP/1.1 200 OK rn'
        response_header = 'Server:pwbrn'
        response_body = file_data
        response_data = (response_line + response_header + 'rn').encode() + response_body
        client_socket.send(response_data)
        client_socket.close()

静态Web服务器升级版本（多任务,解决访问文件不存在等报错问题）

import socket
import threading

def handle_client(client_socket):
    client_request_data = client_socket.recv(1024).decode()
    if len(client_request_data)==1:
        client_socket.close
        return
    requestspath = client_request_data.split(' ')[1]
    if requestspath == '/':
        requestspath = '/index.html'
    try:
        with open('.' + requestspath, 'rb') as fp:
            file_data = fp.read()
    except Exception as e:
        response_line = 'HTTP/1.1 404 Not Found rn'
        response_header = 'Server:pwbrn'
        response_body = "404 Not Found"
        response_data = (response_line + response_header + 'rn' + response_body).encode()
        client_socket.send(response_data)
    else:
        response_line = 'HTTP/1.1 200 OK rn'
        response_header = 'Server:pwbrn'
        response_body = file_data
        response_data = (response_line + response_header + 'rn').encode() + response_body
        client_socket.send(response_data)
    finally:
        client_socket.close()

if __name__ == '__main__':
    tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    tcp_server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True)
    tcp_server_socket.bind(('', 8080))
    tcp_server_socket.listen(128)
    while True:
        client_socket, client_ip = tcp_server_socket.accept()
        client_thread = threading.Thread(target=handle_client, args=(client_socket,))
        client_thread.start()

面向对象版本（方便代码复用）

import socket
import threading

class HttpWebServer:
    def __init__(self):
        self.tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.tcp_server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True)
        self.tcp_server_socket.bind(('', 8080))
        self.tcp_server_socket.listen(128)

    def handle_client(self, client_socket):
        client_request_data = client_socket.recv(1024).decode()
        request_data = client_request_data.split(' ')

        if len(request_data) == 1:
            client_socket.close
            return
        requestspath = request_data[1]
        if requestspath == '/':
            requestspath = '/index.html'
        try:
            with open('.' + requestspath, 'rb') as fp:
                file_data = fp.read()
        except Exception as e:
            response_line = 'HTTP/1.1 404 Not Found rn'
            response_header = 'Server:pwbrn'
            response_body = "404 Not Found"
            response_data = (response_line + response_header + 'rn' + response_body).encode()
            client_socket.send(response_data)

        else:
            response_line = 'HTTP/1.1 200 OK rn'
            response_header = 'Server:pwbrn'
            response_body = file_data
            response_data = (response_line + response_header + 'rn').encode() + response_body
            client_socket.send(response_data)
        finally:
            client_socket.close()

    def start(self):
        while True:
            client_socket, client_ip = self.tcp_server_socket.accept()
            client_thread = threading.Thread(target=self.handle_client, args=(client_socket,))
            client_thread.start()

if __name__ == '__main__':
    my_web_server = HttpWebServer()
    my_web_server.start()

命令行启动动态绑定端口号（最终版）

在文件中引入sys模块用来获取命令行输入内容，在代码中输出sys.argv即可看到如下结果

 在代码中对获取到的argv[1]即输入的端口号进行验证，然后传入方法中，错误则发出提示，结果如下

现在就可以在命令行启动服务器并指定端口号了！！！！

 代码如下：

import socket
import threading
import sys

class HttpWebServer:
    def __init__(self, port):
        self.tcp_server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.tcp_server_socket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, True)
        self.tcp_server_socket.bind(('', port))
        self.tcp_server_socket.listen(128)

    def handle_client(self, client_socket):
        client_request_data = client_socket.recv(1024).decode()
        request_data = client_request_data.split(' ')

        if len(request_data) == 1:
            client_socket.close
            return
        requestspath = request_data[1]
        if requestspath == '/':
            requestspath = '/index.html'
        try:
            with open('.' + requestspath, 'rb') as fp:
                file_data = fp.read()
        except Exception as e:
            response_line = 'HTTP/1.1 404 Not Found rn'
            response_header = 'Server:pwbrn'
            response_body = "404 Not Found"
            response_data = (response_line + response_header + 'rn' + response_body).encode()
            client_socket.send(response_data)

        else:
            response_line = 'HTTP/1.1 200 OK rn'
            response_header = 'Server:pwbrn'
            response_body = file_data
            response_data = (response_line + response_header + 'rn').encode() + response_body
            client_socket.send(response_data)
        finally:
            client_socket.close()

    def start(self):
        while True:
            client_socket, client_ip = self.tcp_server_socket.accept()
            client_thread = threading.Thread(target=self.handle_client, args=(client_socket,))
            client_thread.start()

def main():
    print(sys.argv)
    if len(sys.argv) != 2:
        print("Input Error:Should be python3 xxx.py port")
        return
    if not sys.argv[1].isdigit():
        print("Input Error:Should be python3 xxx.py port")
        return
    port = int(sys.argv[1])
    my_web_server = HttpWebServer(port)
    my_web_server.start()

if __name__ == '__main__':
    main()
