HTTPS Web Server for the ESP32 Chip based on the mbed TLS library packaged with the ESP-IDF SDK.
Include header file:
#include "https_server.h"Define or load TLS certificates and key.
const uint8_t tls_cert[] = "-----BEGIN CERTIFICATE-----\n\
MIIF6jCCA9KgAwIBAgIJANmaOM7RFLbfMA0GCSqGSIb3DQEBCwUAMIGJMQswCQYD\n\
-----END CERTIFICATE-----\n\n";
/* note: truncated for brevity */
const uint8_t tls_key[] = "-----BEGIN PRIVATE KEY-----\n\
MIIJQgIBADANBgkqhkiG9w0BAQEFAASCCSwwggkoAgEAAoICAQDN3BvDFah/ObFA\n\
-----END PRIVATE KEY-----\n\n";
/* note: truncated for brevity */Define a HTTP response callback function:
https_server_response_t hello_response(https_request_t request,
https_response_t *response,
void *user_args)
{
char body[] = "<html>\
<head><title>Hello World</title></head>\
<body><h1>Hello World</h1></body>\
</html>";
https_response_set_body(&response, body);
return HTTPS_SERVER_RESPONSE_OK;
}Initialize the HTTPS server:
https_server_t server;
https_server_config_t server_config = {};
server_config.port = 443;
server_config.tls_cert = tls_cert;
server_config.tls_key = tls_key;
ESP_ERROR_CHECK(https_server_init(&server_config, &server));Associate routes to HTTP response callback:
ESP_ERROR_CHECK(https_server_add_route(&server, "/hello.html", &hello_response));Establish network connection such as WiFi. See the esp-idf wifi examples or the esp-idf ethernet examples.
Start the HTTPS server once the ESP32 is connected to a network:
ESP_ERROR_CHECK(https_server_start(server));
