自定义指令

创建自定义指令

第一步，创建一个自定义命令类文件，新建application/common/command/Hello.php

<?php
namespace app\common\command;
use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;
class Hello extends Command
{
    protected function configure()
    {
        $this->setName('hello')
            ->addArgument('name', Argument::OPTIONAL, "your name")
            ->addOption('city', null, Option::VALUE_REQUIRED, 'city name')
            ->setDescription('Say Hello');
    }
    protected function execute(Input $input, Output $output)
    {
        $name = trim($input->getArgument('name'));
        $name = $name ?: 'thinkphp';
        if ($input->hasOption('city')) {
            $city = PHP_EOL . 'From ' . $input->getOption('city');
        } else {
            $city = '';
        }
        $output->writeln("Hello," . $name . '!' . $city);
    }
}

这个文件定义了一个叫hello的命令，并设置了一个name参数和一个city选项。

第二步，配置application/command.php文件

<?php
return [
    'app\common\command\Hello',
];

第三步，测试-命令帮助-命令行下运行

第四步，运行hello命令

添加命令参数

添加city选项

注意看参数和选项的调用区别
