我正在开发一个客户端,需要解析分块类型的HTTP传输。我一直在努力解决以下问题,但是无法成功,希望有人能够更快地捕捉到我的错误。总结一下问题:似乎客户端没有接收到所有的块,因此导致了后续过程的混乱。提前感谢!
while(cflag){
pfile_chunk = malloc(CHUNK_SIZE+1);
memset(pfile_chunk, 0, CHUNK_SIZE);
cPtr = pfile_chunk;
cPtr2 = NULL;
k=0;
while(*(cPtr-1) != '\n'){
k++;
recv(sock, cPtr, 1, 0);
cPtr = pfile_chunk+k;
}
cPtr2 = strchr(pfile_chunk, '\r');
*cPtr2 = '\0';
sscanf(pfile_chunk, "%x", &l);
if(l == 0)
break;
printf("\nServer wants to deliver %ld bytes.\n", l);
pfile_chunk = realloc(pfile_chunk, l+1);
memset(pfile_chunk, 0, l);
recv(sock, pfile_chunk, l, 0);
fputs(pfile_chunk, f);
printf("GOT THIS, SIZE %ld:\n%s\n", strlen(pfile_chunk), pfile_chunk);
//get next \r\n bytes.
recv(sock, NULL, 2, 0);
}
