如何要求用户在自定义控制台命令中提供输入?
除了用户6827096的答案之外:还有
interactive()
方法,该方法可用于使用问题帮助器从交互输入中预填充所需选项,并且将被调用,除非--没有交互传递给命令:
/**
* Interacts with the user.
*
* This method is executed before the InputDefinition is validated.
* This means that this is the only place where the command can
* interactively ask for values of missing required arguments.
*
* @param InputInterface $input An InputInterface instance
* @param OutputInterface $output An OutputInterface instance
*/
protected function interact(InputInterface $input, OutputInterface $output)
{
}
在Symfony附带的Sensio的Generator捆绑包中可以找到它与问题助手组合使用的一个很好的例子:Hum,是的,在提问之前阅读文档会很有帮助^^当然,但更有用的是谷歌如何要求用户在自定义控制台命令中提供输入?
并移动到这里
/**
* Interacts with the user.
*
* This method is executed before the InputDefinition is validated.
* This means that this is the only place where the command can
* interactively ask for values of missing required arguments.
*
* @param InputInterface $input An InputInterface instance
* @param OutputInterface $output An OutputInterface instance
*/
protected function interact(InputInterface $input, OutputInterface $output)
{
}
