java与C语言socket通信（C客户端java服务端）

服务器端代码 MyServer.java

1. import java.io.*;
2. import java.net.*;
3. import java.util.*;
5. public class MyServer {
6. public static void main(String[] args) throws IOException{
7. ServerSocket server=new ServerSocket(5678);
8. while(true){
9. Socket client=server.accept();
10. BufferedReader in=new BufferedReader(new InputStreamReader(client.getInputStream()));
11. String str=in.readLine();
12. System.out.println(str);
13. client.close();
14. }
15. }
16. }

客户端client.c代码：

2. #include <sys/socket.h>
3. #include <stdio.h>
4. #include <netinet/in.h>
5. #include <arpa/inet.h>
6. #include <unistd.h>
7. #include <stdlib.h>
8. #include <string.h>
10. int main() {
11. int sockfd;
12. int len;
13. struct sockaddr_in address;
14. int result;
15. char ch[100];
16. while(1){
17. sockfd = socket(AF_INET,SOCK_STREAM,0);
18. address.sin_family = AF_INET;
19. address.sin_addr.s_addr = inet_addr("192.168.11.169");
20. address.sin_port = htons(5678);
21. len = sizeof(address);
22. result = connect(sockfd,(struct sockaddr *)&address,len);
23. if(result == -1) {
24. perror("oops:client\n");
25. exit(1);
26. }
27. printf("请输入你要传输的数据\n");
28. gets(ch);
29. len = strlen(ch);
30. printf("vcluster %d, %s\n", len, ch);
31. ch[len] = '\0';
32. printf("%d, %s\n", len, ch);
33. write(sockfd,ch,len+1);
34. close(sockfd);
35. }
36. exit(0);
