<p>emoji表情对于移动端来说，十分常见。可是，最近才发现我们项目还不支持emoji表情。数据库使用的字符集是<code>UTF-8</code>,WTF?还有UTF-8搞不定的？那该用什么？该用<code>utf8mb4</code>。那么，改吧。</p>
<p>要想支持emoji表情，首先数据库版本必须是5.5.3及其以上。如果你的数据库版本还没有达到要求，那么请<a target="_blank" rel="noopener" href="https://dev.mysql.com/downloads/mysql/">升级</a>。版本符合要求的，开始修改数据库、表、字段信息吧。</p>
<ul>
<li>数据库</li>
</ul>
<pre class="line-numbers language-none"><code class="language-none">ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;</code></pre>
<ul>
<li>表</li>
</ul>
<p>将要存储emoji表情的表修改如下:</p>
<pre class="line-numbers language-none"><code class="language-none">ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;</code></pre>
<ul>
<li>字段</li>
</ul>
<pre class="line-numbers language-none"><code class="language-none">ALTER TABLE table_name CHANGE column_name column_name VARCHAR(200) CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;</code></pre>
<p>对于字段，除了字符集设置，其他信息字段类型，长度等请根据自己项目的实际情况设置。</p>
