Webový server
Vibe.d allows writing HTTP(S) web servers in no
time:
auto settings = new HTTPServerSettings;
settings.port = 8080;
listenHTTP(settings, &foo);
This starts a web server on port 8080 where all
requests are handled by a foo function:
void foo(HTTPServerRequest req,
HTTPServerResponse res) { ... }
To ease typical usage patterns and the configuration
of different paths, a URLRouter class is provided
which either allows registering GET, POST etc.
handlers using the .get("path", handler)
and .post("path", handler) member functions, or
registering a custom web interface class which implements
web server paths as member functions:
auto router = new URLRouter;
router.registerWebInterface(new WebService);
listenHTTP(settings, router);
The paths of the custom web interface WebService's member functions
will automatically be deduced using a simple scheme:
index() will handle/index
getName() will handle the GET request /name
postUsername() will handle to POST request
to /username
Custom paths can be set by attributing a member
function with a @path("/hello/world") attribute.
Parameters for POST requests will be made available
to the function using _ prefixed variable names. It is
also possible to specify parameters directly
in the path itself:
@path("/my/api/:id")
void foo(int _id)
You don't need to pass HTTPServerResponse and
HTTPServerRequest as parameter to each function.
Vibe.d statically checks whether it is in a function's parameter list
and just passes it if needed.
