在linxu寫server client的ftp程式 server傳檔至client端檔案會超過原本的file(EX:623655B -> 626688B) 抓不到錯ˊˋ... 奮戰了兩天~~仍然無解..懇請先知幫忙 server: void ftp_getfile(int sockfd,char *op2) { FILE *fp=fopen(op2,"rb"); if(!fp) { printf("cant open the file or filename error:%s\n",op2); strcpy(message.opt2,"error"); send(sockfd,&message,sizeof(message),0); ftp(sockfd);//keyword } while(!feof(fp)) { fread(&message.payload,sizeof(message.payload),1,fp); //fwrite(&message.payload,sizeof(message.payload),1,file); message.value++; send(sockfd,&message,sizeof(message),0); } strcpy(message.opt1,"ok"); printf("傳送%s\n",&message.opt1); send(sockfd,&message,sizeof(message),0); printf("All:%d time\n",message.value); fclose(fp); ftp(sockfd);//keyword } client: void ftp_getfile(FILE *fp,char *op2,int sockfd) { ssize_t n; FILE *file=fopen(op2,"wb"); for(;;){ recv(sockfd,&message,sizeof(message),0); if(strcmp(message.opt2,"error")==0) { printf("**Cant write the file or filename error:%s**\n",op2); ftp(fp,sockfd,message.value); } recv(sockfd,&message,sizeof(message),0); while(strcmp(message.opt1,"ok")!=0) { fwrite(&message.payload,sizeof(message.payload),1,file); recv(sockfd,&message,sizeof(message),0); } printf("接收File %s ok ,all %d time\n",op2,message.value); fclose(file); break; }//for(;;) message.value=0; ftp(fp,sockfd,message.value); } message.payload ->char[1024] value ->int opt1,opt2 ->char[50] 不知道client端的fwrite為什麼會多抓...懇請幫忙.. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.230.130.122
