<div>{{APIRef("Fetch")}}</div>
<p> {{domxref("Body")}} 对象中的<strong><code>formData()</code></strong> 方法将 {{domxref("Response")}} 对象中的所承载的数据流读取并封装成为一个对象，该方法将返回一个 <strong><code>Promise</code></strong> 对象，该对象将产生一个{{domxref("FormData")}} 对象。</p>
<div class="note">
<p><strong>注意</strong>: 该方法主要与 <a href="/en-US/docs/Web/API/ServiceWorker_API">service workers</a> 有关. 如果客户端提交的一个表单请求被Service Worker 所截取，您可以像下述的样例一样，调用 <code>formData()</code> 方法来获取一个key-value 字典, 对该字典可以进行修饰, 然后将修饰后的表填提交给远端服务器 (或在本地应用)。</p>
