## Sobre os códigos de status HTTP

/// note | "Nota"

Se você já sabe o que são códigos de status HTTP, pule para a próxima seção.

///

   *   <li>If a constructor or factory method takes a parameter whose type is interface, a dynamic
   *       proxy will be passed to the method. It's possible that the method body expects an
   *       instance method of the passed-in proxy to be of a certain value yet the proxy isn't aware
   *       of the assumption, in which case the equality check before and after serialization will
   *       fail.

## 什么是容器

容器（主要是 Linux 容器）是一种非常**轻量级**的打包应用程序的方式，其包括所有依赖项和必要的文件，同时它们可以和同一系统中的其他容器（或者其他应用程序/组件）相互隔离。
