我正在尝试使用Buffalo将Elastic APM和Sentry集成到我的网站中。有趣的文件如下:
handlers/sentryHandler.go

package handlers

import (
    sentryhttp "github.com/getsentry/sentry-go/http"
    "github.com/gobuffalo/buffalo"
)

func SentryHandler(next buffalo.Handler) buffalo.Handler {
    handler := buffalo.WrapBuffaloHandler(next)
    sentryHandler := sentryhttp.New(sentryhttp.Options{})

    return buffalo.WrapHandler(sentryHandler.Handle(handler))
}
handlers/elasticAPMHandler.go
package handlers

import (
    "fmt"

    "github.com/gobuffalo/buffalo"
    "go.elastic.co/apm/module/apmhttp"
)

func ElasticAPMHandler(next buffalo.Handler) buffalo.Handler {
    fmt.Println("AAA")
    handler := apmhttp.Wrap(buffalo.WrapBuffaloHandler(next))
    return buffalo.WrapHandler(handler)
}
actions/app.go
package actions

import (
    "github.com/gobuffalo/buffalo"
    "github.com/gobuffalo/envy"
    forcessl "github.com/gobuffalo/mw-forcessl"
    paramlogger "github.com/gobuffalo/mw-paramlogger"
    "github.com/unrolled/secure"

    "my_website/handlers"
    "my_website/models"

    "github.com/gobuffalo/buffalo-pop/pop/popmw"
    csrf "github.com/gobuffalo/mw-csrf"
    i18n "github.com/gobuffalo/mw-i18n"
    "github.com/gobuffalo/packr/v2"
)

func App() *buffalo.App {
    if app == nil {
        app = buffalo.New(buffalo.Options{
            Env:         ENV,
            SessionName: "_my_website_session",
        })

        // Automatically redirect to SSL
        app.Use(forceSSL())

        // Catch errors and send them to Sentry.
        app.Use(handlers.SentryHandler)

        // Get tracing information and send it to Elastic.
        app.Use(handlers.ElasticAPMHandler)

        // Other Buffalo middleware stuff goes here...

        // Routing stuff goes here...
    }

    return app
}

我遇到的问题是,如果我在顶部有Sentry / APM处理程序,那么我会得到类似application.html: line 24: "showPagePath": unknown identifier的错误。但是,如果我在设置路由之前将其移动到,则将出现未找到事务的错误。因此,我猜测处理程序包装程序正在删除buffalo.Context信息。那么,从尝试重新实现其包装程序之后,我需要做什么才能将Sentry和Elastic集成到Buffalo助手中?

最佳答案

因此,我猜想处理程序包装程序将删除buffalo.Context信息。

没错问题是buffalo.WrapHandler(Source)丢弃了除底层http.Request / http.Response之外的所有上下文:

// WrapHandler wraps a standard http.Handler and transforms it
// into a buffalo.Handler.
func WrapHandler(h http.Handler) Handler {
    return func(c Context) error {
        h.ServeHTTP(c.Response(), c.Request())
        return nil
    }
}

那么,从尝试重新实现其包装程序之后,我需要做什么才能将Sentry和Elastic集成到Buffalo助手中?

我可以看到两个选项:
  • 重新实现buffalo.WrapHandler / buffalo.WrapBuffaloHandler以停止丢弃buffalo.Context。这将涉及将buffalo.Context存储在基础http.Request的上下文中,然后在另一侧再次将其拉出,而不是创建一个全新的上下文。
  • 无需使用Wrap*函数即可为Sentry和Elastic APM实现Buffalo专用的中间件。

  • Elastic APM代理中的后一个选项存在一个未解决的问题:elastic/apm#39
