    Create an invoice.

    This will (let's imagine) let the API user (some external developer) create an
    invoice.

    And this path operation will:

    * Send the invoice to the client.
    * Collect the money from the client.
    * Send a notification back to the API user (the external developer), as a callback.
        * At this point is that the API will somehow send a POST request to the

	}
	z.Free, err = dc.ReadUint64()
	if err != nil {
		err = msgp.WrapError(err, "Free")
		return
	}
	z.Used, err = dc.ReadUint64()
	if err != nil {
		err = msgp.WrapError(err, "Used")
		return
	}
	z.UsedInodes, err = dc.ReadUint64()
	if err != nil {
		err = msgp.WrapError(err, "UsedInodes")
		return
	}

    "typescript": "^4.6.2"
  }
}
```

在这里添加 NPM `generate-client` 脚本后，您可以使用以下命令运行它:

<div class="termy">

```console
$ npm run generate-client

frontend-app@1.0.0 generate-client /home/user/code/frontend-app
> openapi-ts --input http://localhost:8000/openapi.json --output ./src/client --client axios
```

</div>

此命令将在 `./src/client` 中生成代码，并将在其内部使用 `axios`（前端HTTP库）。

## Forbid Extra Headers { #forbid-extra-headers }

In some special use cases (probably not very common), you might want to **restrict** the headers that you want to receive.

You can use Pydantic's model configuration to `forbid` any `extra` fields:
