我这个ftp上传文件有时成功，但也比较慢，有时却不成功，TYPE == TYPE_A
void command_put(char *filename)
{
    int infile;
    unsigned char databuf[FILEBUF_SIZE] = "";
    int bytes=0, bytessend = 0;
    
    infile = open(filename,O_RDONLY);
    if(infile == 0)
    {
        rt_kprintf("fopen() failed");
	//close(data_sock);
	return;
    }
    
    if(command_port() == -1) return;
    send_msg("STOR", filename, 1);
    z = lwip_read(server_sock, buffer, sizeof(buffer));
    buffer[z-2] = 0;
    rt_kprintf("%s\n", buffer);

while((bytes = read(infile, databuf, FILEBUF_SIZE)) > 0)
    {
        rt_kprintf("read infile\n");
        rt_kprintf("bytes = %d\n", bytes);
        rt_kprintf("TYPE%d\n", TYPE);
        if(TYPE == TYPE_A)
        {
            rt_kprintf("lwip_write TYPE_A\n");
            //replace((char *)databuf, "\r\n", "\n", FILEBUF_SIZE-1);
            //replace((char *)databuf, "\n", "\r\n", FILEBUF_SIZE-1);
            lwip_write(data_sock, databuf, sizeof(databuf));
        }
        else if(TYPE == TYPE_I)
        {

            lwip_write(data_sock, (const char *)databuf, bytes);
        }

bytessend += bytes;
        memset(&databuf, 0, FILEBUF_SIZE);
    }
    memset(&databuf, 0, FILEBUF_SIZE);
    rt_kprintf("close(infile)\n");
    close(infile);

    return;
