插件上下文接口

宿主侧通过 HttpContext 实现，WASM 侧通过 WasmHttpContext 实现。 插件开发者面向此 trait 编程，不依赖具体实现。

Required Methods

fn request_id(&self) -> String

请求 ID

fn request_ts(&self) -> i64

请求时间戳（毫秒）

fn is_sse(&self) -> bool

是否为 SSE 连接

fn is_websocket(&self) -> bool

是否为 WebSocket 连接

fn get_route_name(&self) -> Option<String>

路由名称

fn get_routing_url(&self) -> Option<String>

路由目标地址

fn get_response_body_size(&self) -> Option<i64>

响应体大小

fn set_response_body_size(&mut self, size: i64)

设置响应体大小

fn log(&self, level: i32, msg: &str)

输出日志（底层接口，level 使用 LOG_* 常量）

fn as_any_mut(&mut self) -> &mut dyn Any

类型擦除，供宿主侧 downcast 获取 HttpContext

Provided Methods

fn log_error(&self, msg: &str)

输出 ERROR 级别日志

fn log_warn(&self, msg: &str)

输出 WARN 级别日志

fn log_info(&self, msg: &str)

输出 INFO 级别日志

fn log_debug(&self, msg: &str)

输出 DEBUG 级别日志

fn log_trace(&self, msg: &str)

输出 TRACE 级别日志

fn http_request(&self, _req: &HttpRequest) -> Result<HttpResponse, PluginError>

发起 HTTP 请求（默认实现返回错误，WASM 侧通过宿主函数重写）

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
