You can get the token header with c.Request.Header["Token"]
.
Here is a sample code.
package main
import (
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.GET("/test", func(c *gin.Context) {
c.JSON(200, gin.H{
"token data": c.Request.Header["Token"],
})
})
r.Run() // listen and serve on 0.0.0.0:8080
}
