在llinux进行图片传输的时候 碰到了一个问题 希望大家能帮忙解决下 就是我在在服务器端不能接受到图片
我的客户端代码
include <stdio.h>
#include <sys/socket.h>
#include <stdlib.h>
#include <sys/types.h>
#include <string.h>
#include <unistd.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <netdb.h>
#define SER_PORT 1900
#define MAX_LEN 256
int main(int argc,char **argv)
{
int sd,rn;
struct sockaddr_in client,server;
char buf[MAX_LEN];
FILE *fq;
int len,opt = 1;
if( ( sd = socket(AF_INET,SOCK_STREAM,0)) == -1 )
{
perror("socket");
exit(1);
}
bzero(&server,sizeof(server));
server.sin_family = AF_INET;
server.sin_port = htons(SER_PORT);
server.sin_addr.s_addr = inet_addr("192.168.150.37");
setsockopt(sd,SOL_SOCKET,SO_REUSEADDR,&opt,sizeof(opt));
if( connect(sd,(struct sockaddr *)&server,sizeof(server)) < 0 )
{
perror("Connect");
close(sd);
exit(1);
}
if( ( fq = fopen("1.jpg","rb") ) == NULL )
{
perror("File open");
close(sd);
exit(1);
}
bzero(buf,sizeof(buf));
while( !feof(fq) )
{
len = fread(buf,1,MAX_LEN,fq);
if( len != write(sd,buf,len) )
{
perror("write");
break;
}
}
close(sd);
fclose(fq);
return 0;
}
这是我服务器代码

int main(int argc, char *argv[])
{
int sockfd,new_fd;
FILE* fp;
struct sockaddr_in server_addr;
struct sockaddr_in client_addr;
int sin_size;
int nbytes;
char buffer[256];
if((sockfd=socket(AF_INET,SOCK_STREAM,0))==-1) {
fprintf(stderr,"Socket error:%s\n\a",strerror(errno));
exit(1);
}
bzero(&server_addr,sizeof(struct sockaddr_in));
server_addr.sin_family=AF_INET;
server_addr.sin_addr.s_addr=htonl(INADDR_ANY);
server_addr.sin_port=htons(portnumber);
if(bind(sockfd,(struct sockaddr *)(&server_addr),sizeof(struct sockaddr))==-1)
{
fprintf(stderr,"Bind error:%s\n\a",strerror(errno));
exit(1);
}
if(listen(sockfd,5)==-1)
{
fprintf(stderr,"Listen error:%s\n\a",strerror(errno));
exit(1);
}
while(1)
{
sin_size=sizeof(struct sockaddr_in);
if((new_fd=accept(sockfd,(struct sockaddr *)(&client_addr),&sin_size))==-1)
{
fprintf(stderr,"Accept error:%s\n\a",strerror(errno));
exit(1);
}
if((nbytes=read(new_fd,buffer,256))==-1)
{
fprintf(stderr,"Read Error:%s\n",strerror(errno));
exit(1);
}
if(nbytes == 1 && buffer[0]=1)
{
break;
}
fp =fopen("mm.jpg","a+");
fwrite(buffer,1,nbytes,fp);
}
close(fp);
close(sockfd);
exit(0);
}
