|
|
// is processed by a http-handler-function of the following form:
|
|
//
|
|
// void HTTP_METHOD_HANDLER( struct mg_connection *, struct http_message *);
|
|
//
|
|
// The purpose of these functions are generally to produce dynamically generated
|
|
// HTTP responses, like JSON. These handler-functions are installed into the HTTP_Server
|
|
// with the member-function <HTTP_Server-object>.install_API_GET_handler. For example:
|
|
//
|
|
// http.server.install_API_GET_handler("vs_connections", &handle_HTTP_GET_vs_connections);
|
|
//
|
|
// installs the function handle_HTTP_GET_vs_connections() with the key "vs_connections".
|
|
// So if, for example the host and port of the webserver is "localhost:8888", and the API_PREFIX is "/api/v1/",
|
|
// then loading the URL "localhost:8888/api/v1/vs_connections" in your browser will cause

// handle_HTTP_GET_vs_connections() to run and return its response, which in this case is a JSON object
|

// describing the variable server connections.

// Variable Server Connections.
