I find example in WiFiS3 -> WifiWebClientSSL after connecting he show result with all page using
void read_request() {
/* -------------------------------------------------------------------------- */
uint32_t received_data_num = 0;
while (client.available()) {
/* actual data reception */
char c = client.read();
/* print data to serial port */
Serial.print(c);
/* wrap data to 80 columns*/
received_data_num++;
if(received_data_num % 80 == 0) {
}
}
}
And show all data
15:15:14.383 -> connected to server
15:15:15.319 -> HTTP/1.1 200 OK
15:15:15.319 -> Server: nginx
15:15:15.319 -> Content-Type: text/html; charset=UTF-8
15:15:15.319 -> Transfer-Encoding: chunked
15:15:15.319 -> Connection: close
15:15:15.319 -> Vary: Accept-Encoding
15:15:15.521 -> Cache-Control: no-cache, private
15:15:15.521 -> Date: Wed, 29 May 2024 12:15:13 GMT
15:15:15.521 -> Set-Cookie: zU0NTk5IiwidGFnIjoiIn0%3D; expires=Wed, 29 May 2024 14:15:13 GMT; Max-Age=7200; path=/; httponly; samesite=lax
15:15:15.890 -> Strict-Transport-Security: max-age=63072000; includeSubdomains;
15:15:15.890 -> All page data - many many lines
How can I tell him to check and display only the header with the status (15:15:15.319 -> HTTP/1.1 200 OK) , thereby saving traffic and time, there is no need to load the entire page.
int st = -1;
if (client.findUntil((char*) "HTTP/1.1 ", (char*) "\n")) {
int l = client.readBytesUntil(' ', buff, sizeof(buff)); // status code
if (l >= 0) {
buff[l] = 0;
if (strlen(buff) == 3) {
st = atoi(buff);
} else {
st = -4;
}
} else {
st = -3;
}
} else {
st = -2;
}
if (st == 200) {
Can you add this in complete code, i try but allready have error
This is full of original code

I try to add this code block in void read_request() but have an error
'buff' was not declared in this scope
if add char buff[256]; its compile good, but not working in serialmonitor.
Can you add you code in right place, very grateful in advance.
For this client/board, a default CA bundle is used when you don't set the cert. I didn't see any reference to what is included in that bundle though. (Google would be in there of course.) Might be baked into the firmware.
