Enum Outcome 

pub enum Outcome {
    Continue,
    Respond(Response),
}

插件控制流

插件阶段返回此枚举，决定网关是继续执行后续插件/流程，还是由插件主动响应并终止。

Variants

Continue

继续执行下一个插件或后续流程

Respond(Response)

主动响应，会终止后续流程，当某个插件处理后，不想继续后续流程时，返回该值

Implementations

impl Outcome

pub fn goon() -> PluginResult

继续执行，等价于 Ok(Outcome::Continue)

pub fn respond( status: u16, headers: Vec<(String, String)>, body: Vec<u8>, ) -> PluginResult

主动响应，会终止后续流程

pub fn reject(status: u16, msg: impl Into<String>) -> PluginResult

拒绝请求，等价于 respond(status, vec![], msg)

用于限流(429)、鉴权失败(403)、参数校验(400) 等场景。

pub fn execute_error(msg: impl Into<String>) -> PluginResult

pub fn not_found(msg: impl Into<String>) -> PluginResult
