Validation

To access the validator call the function GetValidator() in the context object The validator takes two parameters, the first parameter is a map of the data to be validated, and the second parameter is a map of the rules of validation Below is an example for validating an input of email and password

func Login(c *core.Context) *core.Response {
    v := c.GetValidator()
    // the data
    data := map[string]interface{}{
        "email":    "mail@example.com",
        "password": "secret",
    }
    // the validation rules
    rules := map[string]interface{}{
        "email":    "required|email",
        "password": "required|length:6,10",
    }
    // Validate
    vResult := v.Validate(data, rules)
    // check to see if validation failed
    if vResult.Failed() {
        // get error messages in json format
        errorsJson := vResult.GetErrorMessagesJson()
        return c.Response.SetStatusCode(422).Json(errorsJson)
    }
    // Proceed with logging in the user
}
