核心還是使用Python的socket實現的，socket的具體用法前面文章有寫，這里不寫太多注釋。

1.本地搭建python靜態web服務器

在資源目錄打開命令終端，輸入命令：python -m http.server [端口號]，端口號不寫默認8000即可

然后在瀏覽器輸入localhost:8000/資源路徑即可訪問你想訪問的頁面

2.返回固定數據的靜態web服務器

''' 返回固定數據的靜態web服務器 ''' # 導入模塊 import socket# 創建socket對象 static_web_server_socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM) static_web_server_socket.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True) # 設置端口復用 static_web_server_socket.bind(('',7777)) static_web_server_socket.listen(128)# 接收請求() while True:client,ip_port=static_web_server_socket.accept()print(f'客戶端{ip_port[0]}使用端口{ip_port[1]}連接成功...')# 接收客戶端的請求信息request_data=client.recv(1024).decode('gbk')print(request_data)# 讀取資源內容，無論客戶端訪問的哪個文件，返回的都是這個文件with open('static/index.html','rb') as file:file_content=file.read() # 作為響應體# 響應行response_line='HTTP/1.1 200 OK\r\n'# 響應頭response_header='Server: Tengine\r\nContent-Type: text/html; charset=UTF-8\r\nConnection: keep-alive\r\n'# 拼接相應報文(響應行+響應頭+空行+響應體)，需是二進制數據response_data=(response_line+response_header+'\r\n').encode('utf-8')+file_content# 發送報文client.send(response_data)# 關閉客戶端連接client.close()print(f'客戶端{ip_port[0]}關閉連接')# 關閉服務器 static_web_server_socket.close() print('Stop!')

3.返回指定數據的靜態web服務器

''' 返回指定數據的靜態web服務器 '''import socketdef server_start(port):web_server=socket.socket(socket.AF_INET,socket.SOCK_STREAM)web_server.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,True)web_server.bind(('',port))web_server.listen(128)while True:client,ip_port=web_server.accept()print(f'客戶端{ip_port[0]}使用{ip_port[1]}端口連接成功')request_info=client.recv(1024).decode('gbk')if len(request_info)==0:client.close()continue# print(request_info)resource_path=request_info.split()[1]print(f'{ip_port[0]}請求的資源路徑是：{resource_path}')if resource_path=='/':resource_path='index.html'try:with open(f'static/{resource_path}','rb') as f:response_body=f.read()except Exception as e:print('請求的文件不存在，請檢查',e)with open('static/404.html','rb') as f:response_body=f.read()response_line = 'HTTP/1.1 404 NOT FOUND\r\n'else:print('資源請求成功！')response_line='HTTP/1.1 200 OK'finally:response_header='Server:PSWS1.0\r\nContent-Type:text/html;Charset=UTF-8\r\n'response_data=(response_line+response_header+'\r\n').encode()+response_bodyclient.send(response_data)client.close()if __name__ == '__main__':server_start(7777)print('Stop')
