# Verificação Estrita de Content-Type { #strict-content-type-checking }

Por padrão, o **FastAPI** usa verificação estrita do cabeçalho `Content-Type` para corpos de requisição JSON; isso significa que requisições JSON devem incluir um `Content-Type` válido (por exemplo, `application/json`) para que o corpo seja interpretado como JSON.

## Risco de CSRF { #csrf-risk }

# 엄격한 Content-Type 확인 { #strict-content-type-checking }

기본적으로 **FastAPI**는 JSON 요청 본문에 대해 엄격한 `Content-Type` 헤더 검사를 사용합니다. 이는 JSON 요청의 본문을 JSON으로 파싱하려면 유효한 `Content-Type` 헤더(예: `application/json`)를 반드시 포함해야 함을 의미합니다.

## CSRF 위험 { #csrf-risk }

이 기본 동작은 매우 특정한 시나리오에서 **Cross-Site Request Forgery (CSRF)** 공격의 한 유형에 대한 보호를 제공합니다.

이러한 공격은 브라우저가 다음과 같은 경우 CORS 사전 요청(preflight) 검사를 수행하지 않고 스크립트가 요청을 보내도록 허용한다는 점을 악용합니다:
