This is a JWT auth Gin middleware to validate JWT token issued by AWS Cognito identity manager. The implementation of this middleware is based on the AWS documentation on how to verify the JWT token
Here is an example of how can this be invoked. It should be attached to all endpoint you would want to authenticate against the user.
package main
import (
"github.com/gin-gonic/gin"
"github.com/akhettar/gin-jwt-cognito"
)
func main() {
// Creates a gin router with default middleware:
router := gin.Default()
// Create Cognito JWT auth middleware and set it in all authenticated endpoints
mw, err := jwt.AuthJWTMiddleware("<some_iss>", "<some_userpool_id>", "region")
if err != nil {
panic(err)
}
router.GET("/someGet", mw.MiddlewareFunc(), func(context *gin.Context) {
// some implementation
})
router.POST("/somePost", mw.MiddlewareFunc(), func(context *gin.Context) {
// some implementation
})
router.PUT("/somePut", mw.MiddlewareFunc(), func(context *gin.Context) {
// some implementation
})
// By default it serves on :8080 unless a
// PORT environment variable was defined.
router.Run()
}
