</div>
<h1 id="创建rest服务"><span class="header-section-number">1</span> 创建REST服务</h1>
<h2 id="数据库迁移"><span class="header-section-number">1.1</span> 数据库迁移</h2>
<p>这个名字是源自于Ruby On Rails在那时候的印象，不直接使用MySQL的目的在于让我们可以专注于过程。</p>
<h3 id="创建表"><span class="header-section-number">1.1.1</span> 创建表</h3>
<p>表的概念，类似于在Excel中的表，如果你真实不懂数据库。 让我们创建一个athomes的表，为什么是athomes，因为以前在写android程序的时候就叫的是athome，忽略掉这些次要的因素吧。</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash">$ <span class="kw">php</span> artisan migrate:make create_athomes_table</code></pre></div>
<p>打开 app/database/migrations/<strong><em>create_athomes_table.php这里的</em></strong>是由日期和某些东西组成的，修改生成的代码为下面。</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">use</span> Illuminate\Database\Schema\Blueprint<span class="ot">;</span>  
<span class="kw">use</span> Illuminate\Database\Migrations\Migration<span class="ot">;</span>  

<span class="kw">class</span> CreateAthomesTable <span class="kw">extends</span> Migration {
    <span class="kw">public</span> <span class="kw">function</span> up<span class="ot">()</span>  
    {  
        Schema::create<span class="ot">(</span><span class="st">&#39;athomes&#39;</span><span class="ot">,</span> <span class="kw">function</span><span class="ot">(</span>Blueprint <span class="kw">$table</span><span class="ot">)</span>  
        {  
            <span class="kw">$table</span>---&gt;increments<span class="ot">(</span><span class="st">&#39;id&#39;</span><span class="ot">);</span>  
            <span class="kw">$table</span>-&gt;float<span class="ot">(</span><span class="st">&#39;temperature&#39;</span><span class="ot">);</span>  
            <span class="kw">$table</span>-&gt;float<span class="ot">(</span><span class="st">&#39;sensors1&#39;</span><span class="ot">);</span>  
            <span class="kw">$table</span>-&gt;float<span class="ot">(</span><span class="st">&#39;sensors2&#39;</span><span class="ot">);</span>  
            <span class="kw">$table</span>-&gt;boolean<span class="ot">(</span><span class="st">&#39;led1&#39;</span><span class="ot">);</span>  
            <span class="kw">$table</span>-&gt;timestamps<span class="ot">();</span>  
        }<span class="ot">);</span>  
    }  
    <span class="kw">public</span> <span class="kw">function</span> down<span class="ot">()</span>  
    {  
        Schema::drop<span class="ot">(</span><span class="st">&#39;athomes&#39;</span><span class="ot">);</span>  
    }  
}</code></pre></div>
<p>意思大致就是id是自加的，也就是我们在localhost/athome/{id}，当我们创建一个新的数据的时候，会自动加上去，最后一个timestamps批的是时间，会包含创建时间和修改时间。 剩下的temperature,sensors1,sensors2是小数，以及只有真和假的led1。</p>
<h3 id="数据库迁移-1"><span class="header-section-number">1.1.2</span> 数据库迁移</h3>
<p>我们只是写了我们需要的数据的格式而并没有丢到数据库里，</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash">$ <span class="kw">php</span> artisan migrate</code></pre></div>
<p>这个就是我们执行迁移的命令，如果你用phpmyadmin可以直接打开查看，没有的话，可以。</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash">$ <span class="kw">mysql</span> -uroot -p</code></pre></div>
<div class="sourceCode"><pre class="sourceCode sql"><code class="sourceCode sql"><span class="kw">use</span> iot;
<span class="kw">select</span> * <span class="kw">from</span> athomes;</code></pre></div>
<p>就可以看到我们写的东西，那么接下来就是创建RESTful服务了</p>
<h2 id="创建restful"><span class="header-section-number">1.2</span> 创建RESTful</h2>
<p>用下面的代码实现我们称之为Athomes控制器的创建</p>
<div class="sourceCode"><pre class="sourceCode bash"><code class="sourceCode bash">$ <span class="kw">php</span> artisan controller:make AthomesController  </code></pre></div>
<p>就会在app/controllers下面生成下面的代码</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">class</span> AthomesController <span class="kw">extends</span> \BaseController {  
    <span class="kw">public</span> <span class="kw">function</span> index<span class="ot">()</span> {}  
    <span class="kw">public</span> <span class="kw">function</span> create<span class="ot">()</span>  {} 
    <span class="kw">public</span> <span class="kw">function</span> store<span class="ot">()</span> {}  
    <span class="kw">public</span> <span class="kw">function</span> show<span class="ot">(</span><span class="kw">$id</span><span class="ot">)</span> {}  
    <span class="kw">public</span> <span class="kw">function</span> edit<span class="ot">(</span><span class="kw">$id</span><span class="ot">)</span> {}  
    <span class="kw">public</span> <span class="kw">function</span> update<span class="ot">(</span><span class="kw">$id</span><span class="ot">)</span> {}  
    <span class="kw">public</span> <span class="kw">function</span> destroy<span class="ot">(</span><span class="kw">$id</span><span class="ot">)</span> {} 
}</code></pre></div>
<h2 id="laravel-resources"><span class="header-section-number">1.3</span> Laravel Resources</h2>
<p>上面的代码过于沉重，请让我用 Ctrl+C 来带来点知识吧。</p>
<table>

<tr class="header">

<td align="left">/resource/{resource}</td>
<td align="left">destroy</td>
<td align="left">resource.destroy</td>

</tbody>
</table>
<p>所以我们只需要专注于创建 create, edit, show, destory 等等。好吧，你可能没有耐心了，但是在修改这个之前我们需要先在 app/model 加个 class</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">class</span> Athomes <span class="kw">extends</span> Eloquent {  
    <span class="kw">protected</span> <span class="kw">$table</span> = <span class="st">&#39;athomes&#39;</span><span class="ot">;</span>  
}</code></pre></div>
<p>如果你想要的只是控制器Athomes的代码的话。。</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">class</span> AthomesController <span class="kw">extends</span> \BaseController {
    <span class="kw">public</span> <span class="kw">$restful</span>=<span class="kw">true</span><span class="ot">;</span>

<p>希望你能读懂，没有的话，继续。</p>
<p>下面这部分来自于之前的博客，这里就不多加论述了。 这个也就是我们要的模板，</p>
<h3 id="修改create"><span class="header-section-number">1.3.1</span> 修改Create()</h3>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">public</span> <span class="kw">function</span> create<span class="ot">()</span>
{
    <span class="kw">$maxid</span>=Athomes::<span class="fu">max</span><span class="ot">(</span><span class="st">&#39;id&#39;</span><span class="ot">);</span>
    <span class="kw">return</span> View::make<span class="ot">(</span><span class="st">&#39;athome.create&#39;</span><span class="ot">)</span>-&gt;with<span class="ot">(</span><span class="st">&#39;maxid&#39;</span><span class="ot">,</span><span class="kw">$maxid</span><span class="ot">);</span>
}</code></pre></div>
<p>这里需要在app/views/创建一个athome里面创建一个create.blade.php，至于maxid，暂时还不需要，后面会用到show。如果只需要模板，可以简化为</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">public</span> <span class="kw">function</span> create<span class="ot">()</span>

    <span class="kw">return</span> View::make<span class="ot">(</span><span class="st">&#39;athome.create&#39;</span><span class="ot">);</span>
}</code></pre></div>
<p>这里只是对其中代码的进行一下说明。</p>

<h4 id="创建表单之前"><span class="header-section-number">1.3.2.1</span> 创建表单之前</h4>

<p>开关一开始打算用 checkbox，加上 bootstrap-switch 实现 ON OFF 弱弱地觉得还是没掌握好的节奏，所以最后用 select 来实现。</p>
<p>还需要修改一下之前的 create()，添加一行</p>
<div class="sourceCode"><pre class="sourceCode php"><code class="sourceCode php"><span class="kw">return</span> Redirect::to<span class="ot">(</span><span class="st">&#39;athome&#39;</span><span class="ot">);</span></code></pre></div>
