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,那么我会收到类似application.html: line 24: "showPagePath": unknown identifier
的错误。但是,如果我将其移动到设置路线之前,则会收到未找到事务的错误。因此,我猜测处理程序包装程序正在丢弃buffalo.Context
信息。那么,从尝试重新实现包装程序开始,我该怎么做才能将Sentry和Elastic集成到Buffalo助手中?
答案 0 :(得分:0)
因此,我猜想处理程序包装程序将删除buffalo.Context信息。
是的。问题在于,buffalo.WrapHandler
(Source)会丢弃除基础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,从尝试重新实现包装程序开始,我该怎么做才能将Sentry和Elastic集成到Buffalo助手中?
我可以看到两个选项:
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。Wrap*
函数的情况下为Sentry和Elastic APM实现Buffalo专用的中间件。Elastic APM代理中的后一种选项elastic/apm#39中存在一个未解决的问题。
