## Caveat

*Applications that use direct S3 API will work fine, however interactive users uploading content using (when POSTing to the presigned URL an app generates) a popup becomes visible on browser to provide client certs, you would have to manually cancel and continue. This may be annoying to use but there is no workaround for now.*

# 自托管自定义文档 UI 静态资源 { #custom-docs-ui-static-assets-self-hosting }

API 文档使用 Swagger UI 和 ReDoc，它们各自需要一些 JavaScript 和 CSS 文件。

默认情况下，这些文件从一个 <abbr title="Content Delivery Network - 内容分发网络: 一种服务，通常由多台服务器组成，用于提供静态文件，如 JavaScript 和 CSS。它常用于从更接近客户端的服务器提供这些文件，从而提升性能。">CDN</abbr> 提供。

不过你可以自定义：可以指定特定的 CDN，或自行提供这些文件。
