# 严格的 Content-Type 检查 { #strict-content-type-checking }

默认情况下，FastAPI 对 JSON 请求体使用严格的 `Content-Type` 头检查。这意味着，JSON 请求必须包含有效的 `Content-Type` 头（例如 `application/json`），其请求体才会被按 JSON 解析。

## CSRF 风险 { #csrf-risk }

此默认行为在一个非常特定的场景下，可防御一类跨站请求伪造（CSRF）攻击。

这类攻击利用了浏览器的一个事实：当请求满足以下条件时，浏览器允许脚本在不进行任何 CORS 预检的情况下直接发送请求：

- 没有 `Content-Type` 头（例如使用 `fetch()` 携带 `Blob` 作为 body）
- 且不发送任何认证凭据。

这种攻击主要在以下情况下相关：

- 应用在本地（如 `localhost`）或内网中运行
