playframework - 如何在 play 框架 1.2.4 中自定义社交安全模块中的 authenticate() 方法

Question

我想在 play framework 1.2.4 中的 controllers.securesocial 中自定义 authenticate()，因为我需要在登录到使用 play 框架的应用程序之前验证一些事情。

您可以尝试在您的自定义类扩展中验证您的东西，这里UserServicePlugin可以使用 scala 和 java 中的示例：

class MyUserService(application: Application) extends UserServicePlugin(application) {
  /**
   * Finds a user that maches the specified id
   *
   * @param id the user id
   * @return an optional user
   */
  def find(id: UserId):Option[Identity] = {
    // implement me
  }

  /**
   * Finds a user by email and provider id.
   *
   * Note: If you do not plan to use the UsernamePassword provider just provide en empty
   * implementation.
   *
   * @param email - the user email
   * @param providerId - the provider id
   * @return
   */
  def findByEmailAndProvider(email: String, providerId: String):Option[Identity] =
  {
    // implement me
  }

  /**
   * Saves the user.  This method gets called when a user logs in.
   * This is your chance to save the user information in your backing store.
   * @param user
   */
  def save(user: Identity) {
    // implement me
  }

  /**
   * Saves a token.  This is needed for users that
   * are creating an account in the system instead of using one in a 3rd party system.
   *
   * Note: If you do not plan to use the UsernamePassword provider just provide en empty
   * implementation
   *
   * @param token The token to save
   * @return A string with a uuid that will be embedded in the welcome email.
   */
  def save(token: Token) = {
    // implement me
  }


  /**
   * Finds a token
   *
   * Note: If you do not plan to use the UsernamePassword provider just provide en empty
   * implementation
   *
   * @param token the token id
   * @return
   */
  def findToken(token: String): Option[Token] = {
    // implement me
  }

  /**
   * Deletes a token
   *
   * Note: If you do not plan to use the UsernamePassword provider just provide en empty
   * implementation
   *
   * @param uuid the token id
   */
  def deleteToken(uuid: String) {
    // implement me
  }

  /**
   * Deletes all expired tokens
   *
   * Note: If you do not plan to use the UsernamePassword provider just provide en empty
   * implementation
   *
   */
  def deleteExpiredTokens() {
    // implement me
  }
}

这些方法在您的 play 应用程序的整个登录过程生命周期中使用 securesocial 插件调用。
