Copia eso a un archivo `main.py`.

Corre el servidor en vivo:

<div class="termy">

```console
$ uvicorn main:app --reload

Copiez ce code dans un fichier nommé `main.py`.

Démarrez le serveur :

/// warning | "Achtung"

Denken Sie daran, die Option `--reload` zu entfernen, wenn Sie diese verwendet haben.

Die Option `--reload` verbraucht viel mehr Ressourcen, ist instabiler, usw.

Sie hilft sehr während der **Entwicklung**, aber Sie sollten sie **nicht** in der **Produktion** verwenden.

最简单的 FastAPI 文件可能像下面这样：

```Python
{!../../docs_src/first_steps/tutorial001.py!}
```

将其复制到 `main.py` 文件中。

运行实时服务器：

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
<span style="color: green;">INFO</span>:     Started reloader process [28720]

        }

        return false;
    }

    public SynonymMap getSynonymMap() {
        return synonymMap;
    }

    protected void createSynonymMap(final boolean reload) {
        try (Reader rulesReader = getReader(reload)) {
            if (rulesReader instanceof StringReader && ((StringReader) rulesReader).toString().length() == 0) {
                synonymMap = null;
                return;
            }

  - If the error says "Context Parameter 'Branch' missing", it's ok. Click into the error and add a context parameter `Branch` with value `myTestBranch`. Go back and it automatically reloads.
  - If there are any errors, read the error and fix your code.
  - IMPORTANT NOTE: if the first import fails, you have to select and apply `Synchronization disabled`, then repeat the step above.
