# 安全性

有许多方法可以处理安全性、身份认证和授权等问题。

而且这通常是一个复杂而「困难」的话题。

在许多框架和系统中，仅处理安全性和身份认证就会花费大量的精力和代码（在许多情况下，可能占编写的所有代码的 50％ 或更多）。

**FastAPI** 提供了多种工具，可帮助你以标准的方式轻松、快速地处理**安全性**，而无需研究和学习所有的安全规范。

但首先，让我们来看一些小的概念。

## 没有时间？

如果你不关心这些术语，而只需要*立即*通过基于用户名和密码的身份认证来增加安全性，请跳转到下一章。

## OAuth2

OAuth2是一个规范，它定义了几种处理身份认证和授权的方法。

它是一个相当广泛的规范，涵盖了一些复杂的使用场景。

它包括了使用「第三方」进行身份认证的方法。

	_ = x[ErrReplicationBandwidthLimitError-47]

	_ = x[ErrBucketRemoteAlreadyExists-49]
	_ = x[ErrBucketRemoteLabelInUse-50]
	_ = x[ErrBucketRemoteArnTypeInvalid-51]
	_ = x[ErrBucketRemoteArnInvalid-52]
	_ = x[ErrBucketRemoteRemoveDisallowed-53]
	_ = x[ErrRemoteTargetNotVersionedError-54]
	_ = x[ErrReplicationSourceNotVersionedError-55]

    return response.body().string();
  }
}
```

Requirements
------------

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

On Android, OkHttp uses [AndroidX Startup][androidx_startup]. If you disable the initializer in the manifest,
