# Dateien im Request

Mit `File` können sie vom Client hochzuladende Dateien definieren.

/// info

Um hochgeladene Dateien zu empfangen, installieren Sie zuerst <a href="https://andrew-d.github.io/python-multipart/" class="external-link" target="_blank">`python-multipart`</a>.

Z. B. `pip install python-multipart`.

Das, weil hochgeladene Dateien als „Formulardaten“ gesendet werden.

///

## `File` importieren

///

/// warning

You can declare multiple `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `application/x-www-form-urlencoded` instead of `application/json`.

This is not a limitation of **FastAPI**, it's part of the HTTP protocol.

### Decrypt the Request { #decrypt-the-request }

The TLS Termination Proxy would use the encryption agreed to **decrypt the request**, and would transmit the **plain (decrypted) HTTP request** to the process running the application (for example a process with Uvicorn running the FastAPI application).

### 확장된 테스트 파일

이제는 `test_main.py` 를 확장된 테스트들로 수정할 수 있습니다:

{* ../../docs_src/app_testing/app_b/test_main.py *}


클라이언트가 요청에 정보를 전달해야 하는데 방법을 모르겠다면, `httpx`에서 해당 작업을 수행하는 방법을 검색(Google)하거나, `requests`에서의 방법을 검색해보세요. HTTPX는 Requests의 디자인을 기반으로 설계되었습니다.

그 후, 테스트에서도 동일하게 적용하면 됩니다.

예시:

* *경로* 혹은 *쿼리* 매개변수를 전달하려면, URL 자체에 추가한다.
* JSON 본문을 전달하려면, 파이썬 객체 (예를들면 `dict`) 를 `json` 파라미터로 전달한다.
