如何在带有SSL的Mongoose嵌入式web服务器上使用http websocket？

#include "mongoose.h"

static void ev_handler(struct mg_connection *nc, int ev, void *ev_data) {
    if (ev == MG_EV_HTTP_REQUEST) {
        // Handle HTTP request
    } else if (ev == MG_EV_WEBSOCKET_HANDSHAKE_DONE) {
        // Handle WebSocket handshake
    } else if (ev == MG_EV_WEBSOCKET_FRAME) {
        // Handle WebSocket frame
    }
}

int main(void) {
    struct mg_mgr mgr;
    struct mg_connection *nc;

    mg_mgr_init(&mgr, NULL);
    nc = mg_bind(&mgr, "https://localhost:8000", ev_handler);
    mg_set_protocol_http_websocket(nc);

    // Load SSL certificate and private key
    mg_bind_opt_t bind_opts;
    bind_opts.ssl_cert = "path/to/ssl_certificate.pem";
    bind_opts.ssl_key = "path/to/ssl_private_key.pem";
    mg_bind_opt_set(nc, &bind_opts);

    // Enable WebSocket support
    nc->flags |= MG_F_WEBSOCKET;

    while (1) {
        mg_mgr_poll(&mgr, 1000);
    }

    mg_mgr_free(&mgr);

    return 0;
}
