HTTPD_SSL_CONFIG_DEFAULT used to be a MACRO and hence used to return
a const pointer. With a recent change it started not returning a
const variable. This change reverts the function to its MACRO form.
Updated the https_server example to use static declration
Previously with HTTPD_SSL_CONFIG_DEFAULT being a MACRO, the
configuration options could not be applied to it. This was casuing
error in multiple scenarios. For e.g., here user_cert_cb is a part
of httpd_ssl_config_t which this macro defines. But the type of
user_cert_cb (esp_tls_server_callback_t) is only available when it is enabled
in esp-tls. The MACRO however cannot be modified to set the defaults
based on configuration option. This fix solves the issue without
breaking the compatibility
- Can be used to get connection or client information (SSL context)
- E.g. Client certificate, Socket FD, Connection state, etc.
- Added example callback for getting client certificate information in 'https_server/simple' example
Closes https://github.com/espressif/esp-idf/issues/7479
https-server uses the open_fn() callback and potentially overwrites user defined callback. This commit adds the user defined open_fn() to https-server's context and calls it upon openning a session
transport_mode accepts enum httpd_ssl_transport_t instead of true/false.
This will allow for extension to dual mode (server running on both secure and insecure ports) in the future.
