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 \r\n'
response_header = 'Server:pwb\r\n'
response_body = file_data
response_data = (response_line + response_header + '\r\n').encode() + response_body
client_socket.send(response_data)
client_socket.close()
函数说明：setsockopt()用来设置参数s 所指定的socket 状态. 参数level 代表欲设置的网络层, 一般设成SOL_SOCKET 以存取socket 层
SO_REUSEADDR 允许在bind ()过程中本地地址可重复使用
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 \r\n'
response_header = 'Server:pwb\r\n'
response_body = "404 Not Found"
response_data = (response_line + response_header + '\r\n' + response_body).encode()
client_socket.send(response_data)
else:
response_line = 'HTTP/1.1 200 OK \r\n'
response_header = 'Server:pwb\r\n'
response_body = file_data
response_data = (response_line + response_header + '\r\n').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 \r\n'
response_header = 'Server:pwb\r\n'
response_body = "404 Not Found"
response_data = (response_line + response_header + '\r\n' + response_body).encode()
client_socket.send(response_data)
else:
response_line = 'HTTP/1.1 200 OK \r\n'
response_header = 'Server:pwb\r\n'
response_body = file_data
response_data = (response_line + response_header + '\r\n').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 \r\n'
response_header = 'Server:pwb\r\n'
response_body = "404 Not Found"
response_data = (response_line + response_header + '\r\n' + response_body).encode()
client_socket.send(response_data)
else:
response_line = 'HTTP/1.1 200 OK \r\n'
response_header = 'Server:pwb\r\n'
response_body = file_data
response_data = (response_line + response_header + '\r\n').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()
