JAVA CLIENT DEFINE SESSION ID CODE
If a required session is not present, by default a 403 HTTP status code is returned.
JAVA CLIENT DEFINE SESSION ID FULL
You can require a session to be present, optionally require a session or get a full description of possible session decode outcomes.Ĭheck java and scala examples for details. Note that when using cookies, their size is limited to 4KB, so you shouldn't put too much data in there (the signature To create a new client-side session (createĪnd set a new session cookie), you need to use the setSession directive.
The basic directives enable you to set, read and invalidate the session.
JAVA CLIENT DEFINE SESSION ID HOW TO
Here are code samples in scala and java illustrating how to create a session manager where the session content will be a single Long number. Usage can be found here for scala and here for java. Examples of SessionSerializer and MultiValueSessionSerializer (nested types are not supported on purpose, as session data should be small & simple). For case classes, it's mostĬonvenient to use a MultiValueSessionSerializer or ( MultiValueSessionSerializer) which should convert the instance into a String -> String map Support for other types can be added by providing a (an implicit for scala) SessionSerializer ( SessionSerializer). The T type parameter in SessionManager (or SessionManager) determines what data is stored in the session.īasic types like String, Int, Long, Float, Double and Map ( Map) are supported out-of-the box. on the user-agent or other request properties. You can dynamically decide which transport to use, basing e.g. When using headers, you need to store the session (and, if used, refresh-) tokens yourself. Scenarios, session data can be transported using custom headers (the names of the headers are configurable in However, cookies have some security vulnerabilities, and are typically not used in mobile applications. The first approach is the simplest to use,Īs cookies are automatically sent to the server on each request. Session data can be sent to the client using cookies or custom headers. Typically, you would create aliases for the session-related directives which use the right parameters basing on theĬurrent request and logic specific to your application. session transport: usingCookies vs usingHeaders.If refreshableĪnd a refresh token is present, the session will be re-created. session continuity: oneOff vs refreshable specifies what should happen when the session expires.Client-side sessionsĪll session-related directives take at least two parameters: Recommended that all sites use https and all cookies have this attribute set. When using cookies, by default the secure attribute of cookies is not set (for development), however it is
Type Option, you can set it to None by using a none value in the config file (for both java and scala). You can customize any of the default config optionsĮither by modifying them through nf or by modifying the SessionConfig case class. Preferably via nf (then you can safely call omConfig) or by using The only value that you need to provide is -secret, Note that when you change the secret,Ī SessionConfig instance can be created using Typesafe config.
You can generate one with SessionUtil.randomServerSecret(). The secret should be a long, random string unique to each environment your app is You can try out a simple example by running or and opening SessionManager & configurationĪll directives require an (implicit for scala) instance of a SessionManager (or SessionManager), which can be created by providing a server Session data that is sent to the client, and verified when the session token is received back. To prevent forging, serialized session data is signed using a server secret. Storage, while using the latter (which is supported by this library) sessions can be easily deserialized on any server.Ī session is a string token which is sent to the client and should be sent back to the server on every request. The former approach requires sticky sessions or additional shared Or entirely on the client in a serialized format. Sessions can be stored on the server, either in-memory or in a database, with the session id sent to the client, Session cannot be "stolen" or forged easily. Session data typically contains at least the id or username of the logged in user. Or custom headers + local storage, with optional Json Web Tokens format support.Ī comprehensive FAQ is available, along with code examples (in Java, but easy to translate to Scala) which answers many common questions on how sessions work, how to secure them and implement using akka-http. Is a need to maintain user sessions, make sure session data is secure and cannot be tampered with.Īkka-http-session provides directives for client-side session management in web and mobile applications, using cookies Module, originating from spray.io, for building reactive REST services with an elegant DSL.Īkka-http is a great toolkit for building backends for single-page or mobile applications.
