Struct RequestContext 

Source 
pub struct RequestContext {
    pub user_id: i64,
    pub tenant_id: Option<i64>,
    pub username: String,
}
Expand description

请求上下文（网关透传的用户信息）

网关验证 JWT 后，将用户信息通过 HTTP 头透传到下游服务：

  • X-User-Id: 用户 ID
  • X-Tenant-Id: 租户 ID（可选）
  • X-Username: 用户名

Fields§

§user_id: i64

用户 ID

§tenant_id: Option<i64>

租户 ID（可选，无租户时为 None）

§username: String

用户名

Trait Implementations§

impl Clone for RequestContext

Source§

fn clone(&self) -> RequestContext

Returns a duplicate of the value. Read more
1.0.0 · Source§

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source. Read more
Source§

impl Debug for RequestContext

Source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
Source§

impl<S> FromRequestParts<S> for RequestContext
where S: Send + Sync,

Axum Extractor：从请求扩展中提取 RequestContext（必须认证）

使用方式：

async fn handler(ctx: RequestContext) -> impl IntoResponse {
    format!("Hello, user {}", ctx.user_id)
}

如果请求未经网关认证（无 X-User-Id header），返回 401。

Source§

type Rejection = Response<Body>

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.
Source§

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
Source§

impl<S> OptionalFromRequestParts<S> for RequestContext
where S: Send + Sync,

Axum 0.8 可选提取器：支持 Option<RequestContext> 参数

使用方式：

async fn handler(ctx: Option<RequestContext>) -> impl IntoResponse {
    match ctx {
        Some(c) => format!("Hello, user {}", c.user_id),
        None => "Hello, anonymous".to_string(),
    }
}

当请求未附带用户上下文时返回 Ok(None)，不会触发 401 错误。

Source§

type Rejection = Infallible

If the extractor fails, it will use this “rejection” type. Read more
Source§

async fn from_request_parts( parts: &mut Parts, _state: &S, ) -> Result<Option<Self>, Self::Rejection>

Perform the extraction.
