socket编程python+c

python版：

server:

def socket_loop_server_function(): HOST = '192.168.56.1' PORT = 21567 sk = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sk.bind((HOST, PORT)) sk.listen(1) while True: sock, addr = sk.accept() sock.sendall(b'begin') flag=True while flag: data=sock.recv(1024) print("recevied:%s" % data) if data == bytes("msg1",encoding="utf-8"): feedback=input("please input the feedback:") sock.send(bytes(feedback, encoding='utf-8')) if feedback == "over": flag=False if data == bytes("msg3",encoding="utf-8"): feedback = input("please input the feedback:") sock.send(bytes(feedback, encoding='utf-8')) if feedback == "over": flag = False if data == bytes("msg5",encoding="utf-8"): feedback = input("please input the feedback:") sock.send(bytes(feedback, encoding='utf-8')) if feedback == "over": flag = False sock.close() break print("connect finished")client: def socket_loop_customer_function(): HOST = '192.168.56.1' PORT = 21567 client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) client.connect((HOST, PORT)) client.settimeout(10) flag=True while flag: reveived_data=client.recv(1024) print(reveived_data) if reveived_data == bytes("over",encoding="utf-8"): client.close() flag=False time.sleep(2) if reveived_data == bytes("begin",encoding="utf-8"): client.sendall(bytes('msg1', encoding="utf-8")) if reveived_data == bytes("msg2",encoding="utf-8"): client.sendall(bytes('msg3', encoding="utf-8")) if reveived_data == bytes("msg4",encoding="utf-8"): client.sendall(bytes('msg5', encoding="utf-8")) print("connect closed")c语言版：在windows上用codeblocks编写socket需要导入socket的库，在complier中导入libws2_32.a和libwsock32.a

代码如下：

#include <winsock2.h>

#pragma comment(lib , "ws2_32.lib")  #导入库

void socket_function(){ WSADATA wsd; struct sockaddr_in dest; char buf[400]; char sendbuf[400]; WSAStartup( MAKEWORD(2, 2), &wsd);           #加载库 SOCKET socketfd= socket(AF_INET, SOCK_STREAM,IPPROTO_TCP); dest.sin_family=AF_INET; dest.sin_port=htons(21567); dest.sin_addr.s_addr=inet_addr("192.168.56.1"); memset(&(dest.sin_zero),0,sizeof(struct sockaddr_in)); if(connect(socketfd,(struct sockaddr*)&dest,sizeof(struct sockaddr_in)) == -1){ printf("failed %d\n",WSAGetLastError()); } while(1){ printf("connect success\n"); recv(socketfd,buf,1024,0); printf("buf=%s\n",buf);// strcpy(sendbuf,"msg1"); printf("please input the msg:\n"); scanf("%s",sendbuf); send(socketfd,sendbuf,strlen(sendbuf),0); } closesocket(socketfd); WSACleanup();}
