// Bind incoming JSON request to a struct type User struct { Name string `json:"name" binding:"required"` Email string `json:"email" binding:"required,email"` } func createUser(c *gin.Context) { var user User if err := c.ShouldBindJSON(&user); err != nil { c.JSON(http.StatusBadRequest, gin.H{"error": err.Error()}) return } // Validate user data, then create user } // Bind incoming form data to a struct type LoginForm struct { Username string `form:"username" binding:"required"` Password string `form:"password" binding:"required"` } func login(c *gin.Context) { var form LoginForm if err := c.ShouldBind(&form); err != nil { c.HTML(http.StatusBadRequest, "login.html", gin.H{"error": err.Error()}) return } // Authenticate user with login form data }In both examples, the Context Bind package is used to parse and validate incoming requests. It is used to extract data from the request and validate it against the specified struct tags. If the data fails validation, an error is returned and appropriate action taken.
