hi，我是温新，一名PHPer。

为了保持文章完整性，本篇文章仍旧采用从第一步开始的方式进行进行。关于win10实现定时任务那一步本篇文章不再记录，请查看 Laravel进阶系列笔记--(9)Laravel win10下的简单定时任务 这篇文章。

Laravel中使用command实现定时任务

第一步：创建command

php artisan make:command TestCommand

该命令会在app/Console/Commands目录下生成对应的文件。Commands目录默认不存在，执行命令时会自动创建。生成的文件内容如下：

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(152, 26, 26)"><?</span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">php</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">namespace</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">App\Console\Commands</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">use</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">Illuminate\Console\Command</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">class</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">TestCommand</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">extends</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">Command</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 命令名称</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(119, 0, 136)">protected</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$signature</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(170, 17, 17)">'command:name'</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"> <span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 命令描述</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(119, 0, 136)">protected</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$description</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(170, 17, 17)">'Command description'</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(119, 0, 136)">public</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">function</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">__construct</span>()</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    {</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">        <span style="box-sizing: border-box;color: rgb(119, 0, 136)">parent</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">__construct</span>();</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    }</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 定时任务处理逻辑</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(119, 0, 136)">public</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">function</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">handle</span>()</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    {</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">        <span style="box-sizing: border-box;color: rgb(119, 0, 136)">return</span> <span style="box-sizing: border-box;color: rgb(17, 102, 68)">0</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    }</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span>

第二步：修改生成的文件

文件：app/Console/Commands/TestCommand.php

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">use</span> <span style="box-sizing: border-box;color: rgb(0, 0, 0)">Illuminate\Support\Facades\Log</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">protected</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$signature</span> <span style="box-sizing: border-box;color: rgb(152, 26, 26)">=</span> <span style="box-sizing: border-box;color: rgb(170, 17, 17)">'sche:test'</span>;</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">public</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">function</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">handle</span>()</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 需要处理的任务</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(0, 0, 0)">Log</span>::<span style="box-sizing: border-box;color: rgb(0, 0, 0)">info</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'command命执行的定时任务'</span>);</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span>

第三步：调用定时任务

文件：app/Console/Kernel.php

<span style="box-sizing: border-box;padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(119, 0, 136)">protected</span> <span style="box-sizing: border-box;color: rgb(119, 0, 136)">function</span> <span style="box-sizing: border-box;color: rgb(0, 0, 255)">schedule</span>(<span style="box-sizing: border-box;color: rgb(0, 0, 0)">Schedule</span> <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$schedule</span>)</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">{</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(170, 85, 0)">// 传入TestCommand中定义的命令名称</span></span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(0, 85, 170)">$schedule</span><span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">command</span>(<span style="box-sizing: border-box;color: rgb(170, 17, 17)">'sche:test'</span>)<span style="box-sizing: border-box;color: rgb(152, 26, 26)">-></span><span style="box-sizing: border-box;color: rgb(0, 0, 0)">everyMinute</span>()</span><br></br><span style="box-sizing: border-box;padding-right: 0.1px">}</span>

第四步：执行定时任务

这一步跟上篇文章中的 第四步 完全一致，因此本篇文章不再记录。请参考 Laravel进阶系列笔记--(9)Laravel win10下的简单定时任务
