Struct RequestSign 

pub struct RequestSign { /* private fields */ }

Query/body signing helper. 查询串/表单体签名。

Implementations

impl RequestSign

pub fn new(secret: impl Into<String>, window_secs: i64) -> Self

Create a signer with secret and timestamp window (seconds). 使用密钥与时间窗（秒）创建签名器。

pub fn with_dao(self, dao: Arc<SaTokenDao>) -> Self

Attach Dao so nonce values can be consumed once. 挂载 Dao，使 nonce 只能使用一次。

pub fn sign_params( &self, params: &BTreeMap<String, String>, ) -> SaTokenResult<String>

Hex HMAC-SHA256 over the canonical query (excludes the sign field). 对规范查询串做 Hex HMAC-SHA256（排除 sign 字段）。

pub fn create_signed( &self, params: BTreeMap<String, String>, ) -> SaTokenResult<BTreeMap<String, String>>

Insert timestamp + nonce then compute sign. Caller sends the whole map. 写入 timestamp 与 nonce 再计算 sign。调用方发送完整 map。

pub async fn verify_params( &self, params: &BTreeMap<String, String>, provided_sign: &str, ) -> SaTokenResult<()>

Verify signature, timestamp window, and optional nonce uniqueness. 校验签名、时间窗与可选 nonce 唯一性。
