### FastAPI Experts - 1 Year

These are the users that have been [helping others the most with questions in GitHub](help-fastapi.md#help-others-with-questions-in-github){.internal-link target=_blank} during the last year. 🧑‍🔬

{% if people %}
<div class="user-list user-list-center">
{% for user in people.one_year_experts[:20] %}

你可以查看不同时期的 **FastAPI 专家**：

* [上个月](#fastapi-experts-last-month) 🤓
* [三个月](#fastapi-experts-3-months) 😎
* [六个月](#fastapi-experts-6-months) 🧐
* [一年](#fastapi-experts-1-year) 🧑‍🔬

## FastAPI 专家 - 上个月

这些是在过去一个月中 [在 GitHub 上帮助他人解答最多问题](help-fastapi.md#github_1){.internal-link target=_blank} 的用户。 🤓

{% if people %}

* ♻️ Refactor computing FastAPI People, include 3 months, 6 months, 1 year, based on comment date, not discussion date. PR [#11304](https://github.com/tiangolo/fastapi/pull/11304) by [@tiangolo](https://github.com/tiangolo).

!!! warning
    Before setting `convert_underscores` to `False`, bear in mind that some HTTP proxies and servers disallow the usage of headers with underscores.

## Duplicate headers

It is possible to receive duplicate headers. That means, the same header with multiple values.

Then, near the end of the `Dockerfile`, we copy all the code. As this is what **changes most frequently**, we put it near the end, because almost always, anything after this step will not be able to use the cache.

```Dockerfile
COPY ./app /code/app
```
