WecomBackend

Struct WecomBackend 

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

统一出网后端:所有请求都经它转发,负责

  • 持有 token 即注入 Authorization: Bearer <token>(无论端点是否挂 RequireAuth;无 token 则忽略不注入);挂 RequireAuth 的端点在 前置门禁 校验:无可用 token 直接报 AuthError::MissingCredentials, 请求不发出。携带 SuppressAuth 的端点(换取 token 的引导接口)即使有 token 也不注入;
  • 捕获 853004(token 失效)→ 经 TokenProvider 重新换取 token (存储持久化 + 内存缓存)→ 重放原请求一次(未注入 token 的请求不参与刷新)。

扁平响应等请求/响应封装由 wecomx-transport 的 endpoint envelope 驱动, 本层不做特殊分流。

所有载荷均可重放:经 HttpRequestPayload 工厂克隆(Arc 零成本),重放 = 再次 build。

Implementations§

Source§

impl WecomBackend

Source

pub fn new( inner: Arc<dyn TransportBackend>, provider: Option<Arc<dyn TokenProvider>>, token: Option<String>, ) -> Self

Wrap an inner backend with authentication.

provider 为认证来源(None 表示无凭据:不注入、不刷新); token 为初始缓存的 token(如来自凭据存储 / 环境变量)。

Source

pub fn with_bin_name(self, bin_name: impl Into<String>) -> Self

设置错误提示中的命令名(影响门禁 / 刷新失败的引导文案)。

Source

pub fn cached_token(&self) -> Option<String>

当前缓存的 token(构建时注入或刷新后更新)。
