func handleLogin(c *gin.Context) { username := c.PostForm("username") password := c.PostForm("password") // Authenticate user with the provided credentials }
func handleImageUpload(c *gin.Context) { file, err := c.FormFile("image") if err != nil { // Handle error } // Continue with image upload }In this example, we are using DefaultPostForm to retrieve an uploaded image from a form using c.FormFile. The uploaded file is then processed accordingly. Both code examples demonstrate the usefulness of DefaultPostForm to retrieve data submitted in a form within the Context of a Gin application.
