--- title: Sentry menu: docs_patterns weight: 1020 --- # Sentry崩溃报告 [Sentry](https://sentry.io/)是一个崩溃报告系统,它支持基于actix错误报告的failure crate。使用Sentry中间件,可以自动将服务器错误报告给Sentry。 # Sentry中间件 该中间件捕获服务器错误范围(500-599)中的任何错误,并通过其堆栈跟踪将附加的错误发送给哨兵。 要使用中间件,需要初始化和配置Sentry,并且需要添加sentry-actix中间件。此外,注册panic处理程序以通知困难panic也是有意义的。 ```rust extern crate sentry; extern crate sentry_actix; use sentry_actix::SentryMiddleware; use std::env; fn main() { sentry::init("SENTRY_DSN_GOES_HERE"); env::set_var("RUST_BACKTRACE", "1"); sentry::integrations::panic::register_panic_handler(); let mut app = App::with_state(state) .middleware(SentryMiddleware::new()) // ... } ``` # Reusing the Hub 如果使用这种集成,默认的sentry hub(Hub::current())通常是错误的。要获得特定的请求,您需要使用ActixWebHubExt trait: ```rust use sentry::{Hub, Level}; use sentry_actix::ActixWebHubExt; let hub = Hub::from_request(req); hub.capture_message("Something is not well", Level::Warning); ``` The hub can also be made current for the duration of a call. Then Hub::current() works correctly until the end of the run block. ```rust use sentry::{Hub, Level}; use sentry_actix::ActixWebHubExt; let hub = Hub::from_request(req); Hub::run(hub, || { sentry::capture_message("Something is not well", Level::Warning); }); ```
