type: string default: This value is not a valid URL.
This message is shown if the URL is invalid.
type: array default: array('http', 'https')
The protocols that will be considered to be valid. For example, if you also
needed ftp:// type URLs to be valid, you’d redefine the protocols
array, listing http, https, and also ftp.
type: mixed default: null
2.6 新版功能: The payload option was introduced in Symfony 2.6.
This option can be used to attach arbitrary domain-specific data to a constraint. The configured payload is not used by the Validator component, but its processing is completely up to.
For example, you may want to used several error levels to present failed constraint differently in the front-end depending on the severity of the error.
