Dann gehen Sie zur Theke 🔀, zur ursprünglichen Aufgabe, die nun erledigt ist ⏯, nehmen die Burger auf, sagen Danke, und bringen sie zum Tisch. Damit ist dieser Schritt / diese Aufgabe der Interaktion mit der Theke abgeschlossen ⏹. Das wiederum schafft eine neue Aufgabe, „Burger essen“ 🔀 ⏯, aber die vorherige Aufgabe „Burger holen“ ist erledigt ⏹.

### Parallele Hamburger

This includes, for example:

* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
* Processing data:

                            "content": {"application/json": {"schema": {}}},
                        },
                        "500": {
                            "description": "Internal Server Error",
                            "content": {
                                "application/json": {
                                    "schema": {

Because you are running the Uvicorn server directly from your code, you can call your Python program (your FastAPI application) directly from the debugger.

---

For example, in Visual Studio Code, you can:

* Go to the "Debug" panel.
* "Add configuration...".
* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

!!! tip "提示"

    IP `0.0.0.0` 常用于指程序监听本机或服务器上的所有有效 IP。

API 文档还需要 OpenAPI 概图声明 API `server` 位于 `/api/v1`（使用代理时的 URL）。例如：

```JSON hl_lines="4-8"
{
    "openapi": "3.0.2",
    // More stuff here

class HTTPException(StarletteHTTPException):
    """
    An HTTP exception you can raise in your own code to show errors to the client.

    This is for client errors, invalid authentication, invalid data, etc. Not for server
    errors in your code.

    Read more about it in the
    [FastAPI docs for Handling Errors](https://fastapi.tiangolo.com/tutorial/handling-errors/).
