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：
<?php
namespace 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 . '!' . $city);
}
}
这个文件定义了一个叫hello的命令，并设置了一个name参数和一个city选项。
第二步，配置config/console.php文件
<?php
return [
'commands' => [
'hello' => 'app\command\Hello',
]
];
第三步，测试-命令帮助-命令行下运行
php think
输出
Think Console version 0.1
Usage:
command [options] [arguments]
Options:
-h, --help Display this help message
-V, --version Display this console version
-q, --quiet Do not output any message
--ansi Force ANSI output
--no-ansi Disable ANSI output
-n, --no-interaction Do not ask any interactive question
-v|vv|vvv, --verbose Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
Available commands:
build Build Application Dirs
clear Clear runtime file
hello Say Hello
help Displays help for a command
list Lists commands
make
make:controller Create a new resource controller class
make:model Create a new model class
optimize
optimize:autoload Optimizes PSR0 and PSR4 packages to be loaded with classmaps too, good for production.
optimize:config Build config and common file cache.
optimize:schema Build database schema cache.
第四步，运行hello命令
php think hello
输出
Hello thinkphp!
添加命令参数
php think hello kancloud
输出
Hello kancloud!
添加city选项
php think hello kancloud --city shanghai
输出
Hello kancloud!
From shanghai
注意看参数和选项的调用区别
如果需要生成一个指定的命名空间，可以使用：
php think make:command app\index\Command second
支持在控制器的操作方法中直接调用命令，例如：
<?php
namespace app\index\controller;
use think\facade\Console;
class Index
{
public function hello($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!
