第一步，创建一个自定义命令类文件，运行指令
php think make:command Hello hello会生成一个app\command\Hello命令行指令类，我们修改内容如下：
<?phpnamespace app\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 . '!' . $city); }}这个文件定义了一个叫hello的命令，并设置了一个name参数和一个city选项。
第二步，配置config/console.php文件
<?phpreturn [ 'commands' => [ 'hello' => 'app\command\Hello', ]];第三步，测试-命令帮助-命令行下运行
php think输出
Think Console version 0.1Usage: command [options] [arguments]Options: -h, --help Display this help message -V, --version Display this console version -q, --quiet Do not output any message --ansi Force ANSI output --no-ansi Disable ANSI output -n, --no-interaction Do not ask any interactive question -v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debugAvailable commands: build Build Application Dirs clear Clear runtime file hello Say Hello help Displays help for a command list Lists commands make make:controller Create a new resource controller class make:model Create a new model class optimize optimize:autoload Optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production. optimize:config Build config and common file cache. optimize:schema Build database schema cache.第四步，运行hello命令
php think hello输出
Hello thinkphp!添加命令参数
php think hello kancloud输出
Hello kancloud!添加city选项
php think hello kancloud --city shanghai输出
Hello kancloud!From shanghai注意看参数和选项的调用区别
如果需要生成一个指定的命名空间，可以使用：
php think make:command app\index\Command second支持在控制器的操作方法中直接调用命令，例如：
<?phpnamespace app\index\controller;use think\facade\Console;class Index{ public function hello($name) { $output = Console::call('hello', [$name]); return $output->fetch(); }}访问该操作方法后，例如：
http://serverName/index/hello/name/thinkphp页面会输出
Hello thinkphp!use think\\console\\input\\Option; // 无需传值 Option::VALUE_NONE = 1; // 必须传值 Option::VALUE_REQUIRED = 2; // 可选传值 Option::VALUE_OPTIONAL = 4; // 传数组值 Option::VALUE_IS_ARRAY = 8;/*** 添加选项* @param string $name 选项名称* @param string $shortcut 别名* @param int $mode 类型* @param string $description 描述* @param mixed $default 默认值* @return Command*/ public function addOption(string $name, string $shortcut = null, int $mode = null, string $description = '', $default = null)定义如下:
->addOption('adminname', 'p', Option::VALUE_OPTIONAL, '管理员账号')调用方式可以如下:
// 无需任何参数php think install// 使用全名参数php think install --adminuser admin// 使用缩写php think install -u admin指令逻辑中可以这样获取:
$input->getOption('adminname');
