handleRequest method
Attempts to handle a request, according to its hostname.
If none is matched, then true
is returned.
Also returns true
if all of the sub-app's handlers returned
true
.
Implementation
Future<bool> handleRequest(RequestContext req, ResponseContext res) async {
for (var pattern in _patterns) {
// print('${req.hostname} vs $_creators');
if (pattern.allMatches(req.hostname).isNotEmpty) {
// Resolve the entire pipeline within the context of the selected app.
var app = _apps[pattern] ??= (await _creators[pattern]!());
// print('App for ${req.hostname} = $app from $pattern');
// app.dumpTree();
var r = app.optimizedRouter;
var resolved = r.resolveAbsolute(req.path, method: req.method);
var pipeline = MiddlewarePipeline<RequestHandler>(resolved);
// print('Pipeline: $pipeline');
for (var handler in pipeline.handlers) {
// print(handler);
// Avoid stack overflow.
if (handler == handleRequest) {
continue;
} else if (!await app.executeHandler(handler, req, res)) {
// print('$handler TERMINATED');
return false;
} else {
// print('$handler CONTINUED');
}
}
}
}
// Otherwise, return true.
return true;
