// HTTP server example. This server serves both static and dynamic content.
|
|
// It opens two ports: plain HTTP on port 8000 and HTTP on port 8443.
|
|
// It implements the following endpoints:
|
|
// /api/f1 - respond with JSON string {"result": 123}
|
|
// /api/f2/:id - wildcard example, respond with JSON string {"result": "URI"}
|
|
// any other URI serves static files from s_root_dir
|
|
//
|
|
// To enable SSL/TLS (using self-signed certificates in PEM files),
|
|
// 1. make MBEDTLS_DIR=/path/to/your/mbedtls/installation
|
|
// 2. curl -k https://127.0.0.1:8443
