I have some problems when trying to receive http response message of a website.
This is my function:
void Reveive_response(char *resp, SSL *ssl) {
const int BUFFER_SIZE = 1024;
char response[1048576];
char *buffer = NULL; // to read from ssl
char *check = (char *) malloc(BUFFER_SIZE*sizeof(char));
int bytes; // number of bytes actually read
int received = 0; // number of bytes received
buffer = (char *) malloc(BUFFER_SIZE*sizeof(char)); // malloc
memset(response, '\0', sizeof(response)); // response
assign = '\0'
do{
memset(buffer, '\0', BUFFER_SIZE); // empty buffer
bytes = SSL_read(ssl, buffer, BUFFER_SIZE);
if (bytes < 0) {
printf("Error: Receive response\n");
exit(0);
}
if (bytes == 0) break;
received += bytes;
printf("Received...%d bytes\n", received);
strncat(response, buffer, bytes); // concat buffer to response
} while (SSL_pending(ssl)); // while pending
response[received] = '\0';
printf("Receive DONE\n");
printf("Response: \n%s\n", response);
free(buffer);
strcpy(resp, response); // return via resp
}
When I call the function, it seems like the response message is not complete. Like this:
Received...1014 bytes
Received...1071 bytes
Receive DONE
Response:
HTTP/1.1 200 OK
<... something else....>
Vary: Accept-Encoding
Content-Type: text/html
Conne
Then if i call the function again, it returns:
Received...39 bytes
Receive DONE
Response:
ction: keep-alive
Content-Length: 0
The field Connection was split. Why my function didn't receive all the response message? I used do while loop inside. Please tell me where did i go wrong? Thank you.
