HTTP Admin

The HTTP admin provides a service tracker and starts a HTTP web server. The civetweb web server is used as an embedded web server. Websockets are supported by the HTTP admin.

Services can register and implement HTTP requests or websocket support for a specified URI. The supported HTTP requests are: GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS and PATCH. The websocket service can support different callback handlers: connect, ready, data and close.

Aliasing is also supported for both HTTP services and websocket services. Multiple aliases can be added by using the comma as seperator. Adding aliasing is done by adding the following function to the target CMakeFile (fill in and ):

celix_bundle_headers(<TARGET>
        "X-Web-Resource: /<Alias path>$<SEMICOLON>/<Path to destination>, /<Alias path 2>$<SEMICOLON>/<Path to destination>"
)

Bundle alias resources can be added by the with the following function in the bundle CMakefile:

celix_bundle_add_dir(<TARGET> <Document root of bundle> DESTINATION ".")
