# 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);
|
|||
|
|
});
|
|||
|
|
```
