我有个问题。我收到来自服务器的响应作为字符数组。例如:555#200#
。我将数组拆分为555
and200
因为那是我的命令。我想将该命令保存到另一个数组,但我得到了不好的结果。这是我的代码:
void READ_FROM_SERVER(void) {
int read_vkluci = read(sock_descriptor, read_from_server, sizeof(read_from_server));
if (read_vkluci < 0)
printf("Failed reading bytes from server\n");
printf(" %s \n", read_from_server);
if(read_vkluci>0){
char** tokens;
printf("naredbi=%s \n\n", read_from_server);
tokens = str_split(read_from_server, '#');
if (tokens){
int i;
for (i = 0; *(tokens + i); i++){
printf("naredba=%s\n", *(tokens + i));
naredbi_odelno[i]= *(tokens + i);
printf("naredba_odelno=%s\n", naredbi_odelno[i]);
brojnacomandi++;
//free(*(tokens + i));
}
printf("\n");
//free(tokens);
}
}
int p;
for(p=0;p<brojnacomandi;p++){
if (naredbi_odelno[p]==201) {
nadvoresna_komanda = VKLUCI;
printf("VKLUCEN UVLEKUVAC!!!!");
}
if (naredbi_odelno[p]==200) {
nadvoresna_komanda = ISKLUCI;
printf("ISLKUCEN UVLEKUVAC!!!!");
}
if (naredbi_odelno[p]==96) {
printf("TCP_CONN_OK!!!\n");
}
if (naredbi_odelno[p]==211) {
makeTXpaket(STACK_1);
p_tx_buffer_ = &tx_buffer[1];
nbytes = write(fd, tx_buffer, *p_tx_buffer_);
if (nbytes != tx_buffer[1]) {
/* problem! */
printf("error writing on serial port!!!");
}
printf("PRIMAM....\n");
isprateno=0;
}
if (naredbi_odelno[p]==210) {
makeTXpaket( RETURN);
p_tx_buffer_ = &tx_buffer[1];
nbytes = write(fd, tx_buffer, *p_tx_buffer_);
if (nbytes != tx_buffer[1]) {
/* problem! */
printf("error writing on serial port!!!");
}
printf("VRAKAM....\n");
isprateno=0;
}
// else {
// printf("TCP_NOT_OK!!!!\n");
// close(sock_descriptor);
// CONECT_T0_SERVER();
// }
Clean_read_from_server_buff();
Clean_naredbi_odelno();
}
}
char** str_split(char* a_str, const char a_delim){
char** result = 0;
size_t count = 0;
char* tmp = a_str;
char* last_comma = 0;
/* Count how many elements will be extracted. */
while (*tmp){
if (a_delim == *tmp){
count++;
last_comma = tmp;
}
tmp++;
}
/* Add space for trailing token. */
count += last_comma < (a_str + strlen(a_str) - 1);
/* Add space for terminating null string so caller
knows where the list of returned strings ends. */
count++;
result = malloc(sizeof(char*) * count);
if (result){
size_t idx = 0;
char* token = strtok(a_str, "#");
while (token){
assert(idx < count);
*(result + idx++) = strdup(token);
token = strtok(0, "#");
}
assert(idx == count - 1);
*(result + idx) = 0;
}
return result;
}
服务器只发给我 555#,但我得到了naredba_odelno
不好的结果!知道为什么会这样吗?
我怎么做naredba_odelno
=naredba
因为naredba
很好!
输出:
naredbi=555#
naredba=555
naredbi_odelno=
……成绩不好为什么?
