HTTP Websocket server with SSL support
This example creates a SSL server and employs a simple Websocket request handler. It demonstrates handling multiple clients from the server including:
- PING-PONG mechanism
- Sending asynchronous messages to all clients
See the esp_https_server component documentation for details.
Before using the example, open the project configuration menu (idf.py menuconfig) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/README.md for more details.
Websocket support in http_server
Please refer to the documentation of Websocket server feature in the documentation, or to the description of using websocket handlers in httpd in the simple ws echo example.
Certificates
You will need to approve a security exception in your browser. This is because of a self signed certificate; this will be always the case, unless you preload the CA root into your browser/system as trusted.
You can generate a new certificate using the OpenSSL command line tool:
openssl req -newkey rsa:2048 -nodes -keyout prvtkey.pem -x509 -days 3650 -out cacert.pem -subj "/CN=ESP32 HTTPS server example"
Expiry time and metadata fields can be adjusted in the invocation.
Please see the openssl man pages (man openssl-req) for more details.
It is strongly recommended to not reuse the example certificate in your application; it is included only for demonstration.
