## 重新启动

与确保应用程序在启动时运行类似，您可能还想确保它在挂掉后**重新启动**。

### 我们会犯错误

作为人类，我们总是会犯**错误**。 软件几乎*总是*在不同的地方隐藏着**bug**。 🐛

作为开发人员，当我们发现这些bug并实现新功能（也可能添加新bug😅）时，我们会不断改进代码。

### 自动处理小错误

使用 FastAPI 构建 Web API 时，如果我们的代码中存在错误，FastAPI 通常会将其包含到触发错误的单个请求中。 🛡

对于该请求，客户端将收到 **500 内部服务器错误**，但应用程序将继续处理下一个请求，而不是完全崩溃。

### 更大的错误 - 崩溃
