Request ID middleware for Gin Framework. Adds an indentifier to the response using the X-Request-ID header. Passes the X-Request-ID value back to the caller if it's sent in the request headers.
Usage
Start using it
Download and install it.
go get github.com/gin-contrib/requestid
Import it in your code, then use it:
import"github.com/gin-contrib/requestid"
Config
define your custom generator function:
funcmain() {
r:=gin.New()
r.Use(
requestid.New(
requestid.WithGenerator(func() string {
return"test"
}),
requestid.WithCustomHeaderStrKey("your-customer-key"),
),
)
// Example ping request.r.GET("/ping", func(c*gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080r.Run(":8080")
}
Example
package main
import (
"fmt""net/http""time""github.com/gin-contrib/requestid""github.com/gin-gonic/gin"
)
funcmain() {
r:=gin.New()
r.Use(requestid.New())
// Example ping request.r.GET("/ping", func(c*gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080r.Run(":8080")
}
How to get the request identifier:
// Example / request.r.GET("/", func(c*gin.Context) {
c.String(http.StatusOK, "id:"+requestid.Get(c))
})
You can also get the request identifier from response header:
