Python搭建静态web服务器

核心还是使用Python的socket实现的，socket的具体用法前面文章有写，这里不写太多注释。

1.本地搭建python静态web服务器

在资源目录打开命令终端，输入命令：python -m http.server [端口号]，端口号不写默认8000即可

然后在浏览器输入localhost:8000/资源路径即可访问你想访问的页面

2.返回固定数据的静态web服务器

'''返回固定数据的静态web服务器'''# 导入模块import socket# 创建socket对象static_web_server_socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)static_web_server_socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True) # 设置端口复用static_web_server_socket.bind(('',7777))static_web_server_socket.listen(128)# 接收请求()while True:client,ip_port=static_web_server_socket.accept()print(f'客户端{ip_port[0]}使用端口{ip_port[1]}连接成功...')# 接收客户端的请求信息request_data=client.recv(1024).decode('gbk')print(request_data)# 读取资源内容，无论客户端访问的哪个文件，返回的都是这个文件with open('static/index.html','rb') as file:file_content=file.read() # 作为响应体# 响应行response_line='HTTP/1.1 200 OK\r\n'# 响应头response_header='Server: Tengine\r\nContent-Type: text/html; charset=UTF-8\r\nConnection: keep-alive\r\n'# 拼接相应报文(响应行+响应头+空行+响应体)，需是二进制数据response_data=(response_line+response_header+'\r\n').encode('utf-8')+file_content# 发送报文client.send(response_data)# 关闭客户端连接client.close()print(f'客户端{ip_port[0]}关闭连接')# 关闭服务器static_web_server_socket.close()print('Stop!')

3.返回指定数据的静态web服务器

4.多任务版静态web服务器
