<p>api订阅策略在admin后台，你可以通过<code>Rate Limiting Policies>Subscription Policies</code>来添加和修改自定义的策略，并且它可以在使用次数(count)，使用带宽( Bandwidth)，异常事件数量等方面对请求进行限制。</p>

<p><strong>被限流后，将返回这个错误</strong></p>
<pre><code># http 429

"code": "900804",
"message": "Message throttled out",
"description": "You have exceeded your quota .You can access API after 2025-Jun-10 09:40:00+0000 UTC",

<h1 id="api订阅的锁定">api订阅的锁定</h1>
<p><strong>开发者平台，在应用中看到api的锁定状态</strong></p>

<p><strong>发布者对api管理员，可以锁定某个api，可能对发布者管理员来说，某个应用使用不太正常，需要禁用它对api的访问</strong></p>
<p><img src="https://images.cnblogs.com/cnblogs_com/lori/2430318/o_250610090924_block2.png"></p>
<p><strong>应用订阅的api被锁定后，应用再调用api时，返回这个错误</strong></p>
<pre><code># http 401
{
"code": "900907",
"message": "The requested API is temporarily blocked",
"description": "Access failure for API: /user-register/1.0.0, version: 1.0.0 status: (900907) - The requested API is temporarily blocked"
}
</code></pre>
<p><strong>锁定api的接口</strong></p>
<pre><code>/api/am/publisher/v4/subscriptions/block-subscription?subscriptionId=e55f1158-e291-4de4-a6e4-c500b902d025&blockState=BLOCKED
</code></pre>
<p><strong>api订阅状态修改后生效的缓存时间</strong></p>
<ul>
<li>从文档上看，缓存是15分钟，如果你把api里的应用订阅改成blocking，15分钟后应用将不能访问当前api</li>

<p><strong>关闭缓存，配置实时生效</strong></p>
<blockquote>
<p>如果您不接受缓存的时长，或者需要实时让配置生效，那可以把缓存关闭</p>
