This module provides a reusable authentication middleware for Gin-based Go applications. It validates JWT tokens by making a request to an authentication service.
go get github.com/yourusername/go-auth-middlewareHere's how to use the middleware in your Gin application:
import (
"github.com/gin-gonic/gin"
"github.com/yourusername/go-auth-middleware"
)
func main() {
r := gin.Default()
// Create a new instance of AuthMiddleware with configuration
authMiddleware := authmiddleware.New(authmiddleware.Config{
AuthServiceURL: "http://auth-service-url", // Use your actual auth service URL here
})
// Use the middleware for protected routes
protected := r.Group("/")
protected.Use(authMiddleware.Middleware())
{
protected.GET("/profile", getProfile)
}
r.Run(":8080")
}
func getProfile(c *gin.Context) {
// The user ID is now available in the context
userID, _ := c.Get("userID")
// Use the userID...
}The AuthMiddleware can be configured with the following options:
AuthServiceURL: The URL of the authentication service used to validate tokens
You can extend the Config struct with additional options as needed for your specific use case.
