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.
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"
define your custom generator function:
func main() {
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 0.0.0.0:8080
r.Run(":8080")
}
package main
import (
"fmt"
"net/http"
"time"
"github.com/gin-contrib/requestid"
"github.com/gin-gonic/gin"
)
func main() {
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 0.0.0.0:8080
r.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:
> curl -i "http://127.0.0.1:8080" HTTP/1.1 200 OK Content-Type: text/plain; charset=utf-8 X-Request-ID: 77966910-3912-4193-9b74-267491c51700 Content-Length: 39 id:77966910-3912-4193-9b74-267491c51700
When http request with custom identifier, gin server return the custom identifier in response header.
> curl -i -H "X-Request-ID:test" "http://127.0.0.1:8080" HTTP/1.1 200 OK Content-Type: text/plain; charset=utf-8 X-Request-Id: test Content-Length: 13 id:test
