SaStorageDistributedStorage

Struct SaStorageDistributedStorage 

Source
pub struct SaStorageDistributedStorage { /* private fields */ }
Expand description

基于 SaStorage 的分布式 Session 存储实现 把分布式 Session、登录索引、服务凭证统一持久化到任意 SaStorage 后端(Redis / 内存 / 数据库)

§存储键格式

  • Session: {prefix}dsession:{session_id}
  • 登录索引: {prefix}dsession:index:{login_id}
  • 服务凭证: {prefix}dservice:{service_id}

Implementations§

Source§

impl SaStorageDistributedStorage

Source

pub fn new(storage: Arc<dyn SaStorage>, key_prefix: impl Into<String>) -> Self

创建适配器

§参数
  • storage: 底层存储实现(可直接复用全局 SaTokenManager 使用的同一个 storage)
  • key_prefix: 存储键前缀,建议传入 config.storage_key_prefix.clone() 以保持一致

Trait Implementations§

Source§

impl DistributedSessionStorage for SaStorageDistributedStorage

Source§

fn save_session<'life0, 'async_trait>( &'life0 self, session: DistributedSession, ttl: Option<Duration>, ) -> Pin<Box<dyn Future<Output = Result<(), SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

保存 Session

  1. 写入会话本体(带 TTL,由后端控制过期)
  2. 更新登录索引(永久保存,去重;过期 session 在读取时被过滤清理)
Source§

fn get_session<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<DistributedSession>, SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

按 session_id 读取会话 未找到或已过期返回 None

Source§

fn delete_session<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

删除会话

  1. 先读出会话以获得 login_id(用于维护索引)
  2. 删除会话本体
  3. 从登录索引中移除该 session_id(无剩余则删除整个索引键)
Source§

fn get_sessions_by_login_id<'life0, 'life1, 'async_trait>( &'life0 self, login_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<DistributedSession>, SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

获取某用户全部会话 顺带清理索引中已过期/丢失的 session_id(best-effort 清理,避免索引无限膨胀)

Source§

fn save_credential<'life0, 'async_trait>( &'life0 self, credential: ServiceCredential, ) -> Pin<Box<dyn Future<Output = Result<(), SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

保存服务凭证(永久保存)

Source§

fn get_credential<'life0, 'life1, 'async_trait>( &'life0 self, service_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Option<ServiceCredential>, SaTokenError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

按 service_id 读取服务凭证 未找到返回 None
