+
+<p class="summary"><code><strong>EventSource</strong></code> 是服务器推送的一个网络事件接口。一个EventSource实例会对HTTP服务开启一个持久化的连接，以<code>text/event-stream</code> 格式发送事件, 会一直保持开启直到被要求关闭。</p>
+
+<p>一旦连接开启，来自服务端传入的消息会以事件的形式分发至你代码中。如果接收消息中有一个事件字段，触发的事件与事件字段的值相同。如果没有事件字段存在，则将触发通用事件。</p>
+
+<p>与 <a href="/en-US/docs/Web/API/WebSockets_API">WebSockets</a>,不同的是，服务端推送是单向的。数据信息被单向从服务端到客户端分发. 当不需要以消息形式将数据从客户端发送到服务器时，这使它们成为绝佳的选择。例如，对于处理社交媒体状态更新，新闻提要或将数据传递到客户端存储机制（如IndexedDB或Web存储）之类的，EventSource无疑是一个有效方案。</p>

+ <dd>Fired when a connection to an event source has opened.</dd>
+</dl>
+
+<p>Additionally, the event source itself may send messages with an event field, which will create ad-hoc events keyed to that value.</p>
+
+<h2 id="示例">示例</h2>
+
+<p>In this basic example, an <code>EventSource</code> is created to receive unnamed events from the server; a page with the name <code>sse.php</code> is responsible for generating the events.</p>
+
+<pre class="brush: js">var evtSource = new EventSource('sse.php');
+var eventList = document.querySelector('ul');
+
+evtSource.onmessage = function(e) {
+  var newElement = document.createElement("li");
+
+  newElement.textContent = "message: " + e.data;
+  eventList.appendChild(newElement);
+}</pre>
+
+<p>Each received event causes our <code>EventSource</code> object's <code>onmessage</code> event handler to be run. It, in turn, creates a new {{HTMLElement("li")}} element and writes the message's data into it, then appends the new element to the list element already in the document.</p>
+
+<div class="note">
+<p><strong>Note</strong>: You can find a full example on GitHub — see <a href="https://github.com/mdn/dom-examples/tree/master/server-sent-events">Simple SSE demo using PHP.</a></p>
+</div>
+
+<p>To listen to named events, you'll require a listener for each type of event sent.</p>
+
+<pre class="brush: js">  const sse = new EventSource('/api/v1/sse');
+
+  /* This will listen only for events
+   * similar to the following:
+   *
+   * event: notice
+   * data: useful data
+   * id: someid
+   *
+   */
+  sse.addEventListener("notice", function(e) {
+    console.log(e.data)
+  })
+
+  /* Similarly, this will listen for events
+   * with the field `event: update`
+   */
+  sse.addEventListener("update", function(e) {
+    console.log(e.data)
+  })
+
+  /* The event "message" is a special case, as it
+   * will capture events without an event field
+   * as well as events that have the specific type
+   * `event: message` It will not trigger on any
+   * other event type.
