OpenAPI 有一种定义多个安全「方案」的方法。

通过使用它们，你可以利用所有这些基于标准的工具，包括这些交互式文档系统。

OpenAPI 定义了以下安全方案：

* `apiKey`：一个特定于应用程序的密钥，可以来自：
    * 查询参数。
    * 请求头。
    * cookie。
* `http`：标准的 HTTP 身份认证系统，包括：
    * `bearer`: 一个值为 `Bearer ` 加令牌字符串的 `Authorization` 请求头。这是从 OAuth2 继承的。
    * HTTP Basic 认证方式。
    * HTTP Digest，等等。
* `oauth2`：所有的 OAuth2 处理安全性的方式（称为「流程」）。
    *以下几种流程适合构建 OAuth 2.0 身份认证的提供者（例如 Google，Facebook，X (Twitter)，GitHub 等）：
