在两个文件中都定义文件头和用到的宏:
#define MAX_SIZE 10#define ONE_PAGE 4096struct FileHead{ char str[260]; int size;};
在客户端发送接收阶段:
//1.发送文件头 char path[260] = { 0}; cout<<"请输入文件路径"<>path; //截取文件名 char* ptemp = path; while(*ptemp++ != '\0'); while(*(--ptemp) != '\\'); ptemp++; fstream fs; fs.open(path,fstream::in|fstream::binary); fs.seekg(0,fstream::end);//以最后的位置为基准不偏移 int nlen = fs.tellg();//取得文件大小 fs.seekg(0,fstream::beg); FileHead fh; fh.size = nlen; memcpy(fh.str,ptemp,MAX_PATH); nlen = send(sockConnect ,(char*)&fh,sizeof(fh),0); //2,.如果接受到的内容为是 char szResult[MAX_SIZE] = { 0}; recv(sockConnect,szResult,sizeof(szResult),0); char szBuf[ONE_PAGE] ={ 0}; if(0 == strcmp(szResult,"是")) { //读文件 while(!fs.eof()) { fs.read(szBuf,ONE_PAGE); int len = fs.gcount(); //if(len == 0 ) break; send(sockConnect,szBuf,len,0); } } //3.关闭文件流 fs.close();
在服务器端,接收和发送阶段
char str[1024] = { 0}; int nlen; nlen = recv(sockWaiter,(char*)&fh,sizeof(fh),0); cout<<"是否要接受文件"<>str; send(sockWaiter ,str,sizeof(str),0); char szPath[MAX_SIZE] = { 0}; cout<<"请输入要存储的路径"< >szPath; char szPathName[MAX_SIZE] = { 0}; sprintf(szPathName,"%s%s",szPath,fh.str);//拼接路径和文件名 cout< < 0) { fs.write(content,len); FileSize -= len; } } fs.close();
