Hyperf 的命令列預設由 [hyperf/command](https://github.com/hyperf/command) 元件提供,而該元件本身也是基於 [symfony/console](https://github.com/symfony/console) 的抽象。

# 安裝

|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
通常來說該元件會預設存在,但如果您希望用於非 Hyperf 專案,也可通過下面的命令依賴 [hyperf/command](https://github.com/hyperf/command) 元件:
|
2019-06-21 18:14:17 +08:00
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
composer require hyperf/command
|
|
|
|
|
```
|
|

# 檢視命令列表

|
|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
直接執行 `php bin/hyperf.php` 不帶任何的引數即為輸出命令列表。

## 生成命令
|
|
|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
如果你有安裝 [hyperf/devtool](https://github.com/hyperf/devtool) 元件的話,可以通過 `gen:command` 命令來生成一個自定義命令:
|
2019-06-21 18:14:17 +08:00
|
|
|
|
|
|
|
|
|
```bash
|
|
|
|
|
php bin/hyperf.php gen:command FooCommand
|
|
|
|
|
```
|
2019-12-12 16:24:04 +08:00
|
|
|
|
執行上述命令後,便會在 `app/Command` 資料夾內生成一個配置好的 `FooCommand` 類了。
|
2019-06-21 18:14:17 +08:00
|
|
|
|

2019-12-12 16:24:04 +08:00
|
|
|
|
### 定義命令

|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
定義該命令類所對應的命令有兩種形式,一種是通過 `$name` 屬性定義,另一種是通過建構函式傳參來定義,我們通過程式碼示例來演示一下,假設我們希望定義該命令類的命令為 `foo:hello`:
|
2019-06-21 18:14:17 +08:00
|
|
|
|

2019-12-12 16:24:04 +08:00

#### `$name` 屬性定義:

### 定義命令類邏輯
|
2019-06-21 18:14:17 +08:00
|
|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
命令類實際執行的邏輯是取決於 `handle` 方法內的程式碼,也就意味著 `handle` 方法就是命令的入口。
|

protected $name = 'foo:hello';
|

|
|

public function handle()
|
|
|
|

{
|
2019-12-12 16:24:04 +08:00
|
|
|
|
// 通過內建方法 line 在 Console 輸出 Hello Hyperf.
|
2019-06-21 18:14:17 +08:00
|
|
|
|
$this->line('Hello Hyperf.', 'info');
|

### 定義命令類的引數
|
2019-06-21 18:14:17 +08:00
|
|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
在編寫命令時,通常是通過 `引數` 和 `選項` 來收集使用者的輸入的,在收集一個使用者輸入前,必須對該 `引數` 或 `選項` 進行定義。
|
2019-06-21 18:14:17 +08:00
|

2019-12-12 16:24:04 +08:00

#### 引數

|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
假設我們希望定義一個 `name` 引數,然後通過傳遞任意字串如 `Hyperf` 於命令一起並執行 `php bin/hyperf.php foo:hello Hyperf` 輸出 `Hello Hyperf`,我們通過程式碼來演示一下:
|
2019-06-21 18:14:17 +08:00
|
|
|
|
|
|
|
|
|
```php

declare(strict_types=1);

public function handle()
|

2019-12-12 16:24:04 +08:00
|

$argument = $this->input->getArgument('name') ?? 'World';
|

$this->line('Hello ' . $argument, 'info');
|
|
|

}
|
|
|
|
|
|
|
|
|
|
protected function getArguments()
|
|
|
|
|
{
|
|
|
|
|
return [
|
2019-12-12 16:24:04 +08:00
|
|
|
|
['name', InputArgument::OPTIONAL, '這裡是對這個引數的解釋']

2019-06-21 18:14:17 +08:00

```
|
|
|
|
|
|
2019-12-12 16:24:04 +08:00
|
|
|
|
執行 `php bin/hyperf.php foo:hello Hyperf` 我們就能看到輸出了 `Hello Hyperf` 了。
