HttpSession class - dart:io library (original) (raw)
The HttpRequest.session of an HttpRequest.
Stores arbitrary information about a browser session on the server. This information is stored in memory so it will be lost when the server exits.
A cookie named "DARTSESSID" is stored on the browser to associate theHttpSession with a particular client.
import 'dart:io';
void main() async {
HttpServer.bind("localhost", 8080).then((server) {
server.listen((request) {
final session = request.session;
if (session.isNew) {
session["cart"] = [];
}
if (request.uri.queryParameters['buy'] != null) {
final item = request.uri.queryParameters['buy'];
session["cart"].add(item);
}
session["cart"].cast<String>().forEach(request.response.writeln);
request.response.close();
});
});
}

inherited
addEntries(Iterable<MapEntry> newEntries)→ void
Adds all key/value pairs of newEntries to this map.
inherited
Provides a view of this map as having RK keys and RV instances, if necessary.
inherited
clear()→ void

inherited
containsKey(Object? key)→ bool
Whether this map contains the given key.
inherited
containsValue(Object? value)→ bool
Whether this map contains the given value.
inherited
destroy()→ void
Destroys the session.
forEach(void action(dynamic key, dynamic value))→ void
Applies action to each key/value pair of the map.
inherited
map<K2, V2>(MapEntry<K2, V2> convert(dynamic key, dynamic value))→ Map<K2, V2>
Returns a new map where all entries of this map are transformed by the given convert function.
inherited
noSuchMethod(Invocation invocation)→ dynamic
Invoked when a nonexistent method or property is accessed.
inherited
putIfAbsent(dynamic key, dynamic ifAbsent())→ dynamic
Look up the value of key, or add a new entry if it isn't there.
inherited
Removes key and its associated value, if present, from the map.
inherited
removeWhere(bool test(dynamic key, dynamic value))→ void

inherited
Operators
operator ==(Object other)→ bool
The equality operator.
inherited
operator [](Object? key)→ dynamic

inherited
operator []=(dynamic key, dynamic value)→ void
Associates the key with the given value.
