# Request Parameters

Here's the reference information for the request parameters.

These are the special functions that you can put in *path operation function* parameters or dependency functions with `Annotated` to get data from the request.

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python

# Request-Parameter

Hier die Referenzinformationen für die Request-Parameter.

Dies sind die Sonderfunktionen, die Sie mittels `Annotated` in *Pfadoperation-Funktion*-Parameter oder Abhängigkeitsfunktionen einfügen können, um Daten aus dem Request abzurufen.

Dies beinhaltet:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

Sie können diese alle direkt von `fastapi` importieren:

```python

    {!> ../../../docs_src/body/tutorial004.py!}
    ```

The function parameters will be recognized as follows:

* If the parameter is also declared in the **path**, it will be used as a path parameter.
* If the parameter is of a **singular type** (like `int`, `float`, `str`, `bool`, etc) it will be interpreted as a **query** parameter.

Um diese zu konfigurieren, übergeben Sie das Argument `swagger_ui_parameters` beim Erstellen des `FastAPI()`-App-Objekts oder an die Funktion `get_swagger_ui_html()`.

`swagger_ui_parameters` empfängt ein Dict mit den Konfigurationen, die direkt an die Swagger-Oberfläche übergeben werden.

!!! info
    `Form` is a class that inherits directly from `Body`.

!!! tip
    To declare form bodies, you need to use `Form` explicitly, because without it the parameters would be interpreted as query parameters or body (JSON) parameters.

## About "Form Fields"

The way HTML forms (`<form></form>`) sends the data to the server normally uses a "special" encoding for that data, it's different from JSON.

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

            override fun publish(record: LogRecord) {
              super.publish(record)

              val parameters = record.parameters
              if (sslDebug && record.loggerName == "javax.net.ssl" && parameters != null) {
                System.err.println(parameters[0])
              }
            }
          }

        if (debug) {
          handler.level = Level.ALL

     * Builds a project descriptor from the specified POM file.
     *
     * @param projectFile The POM file to build the project from, must not be {@code null}.
     * @param request The project building request that holds further parameters, must not be {@code null}.
     * @return The result of the project building, never {@code null}.
     * @throws ProjectBuildingException If the project descriptor could not be successfully built.

        text(
            "additional.gradle.parameters",
            "",
            display = ParameterDisplay.NORMAL,
            allowEmpty = true,
            description = "The extra gradle parameters you want to pass to this build, e.g. `-PrerunAllTests` or `--no-build-cache`"
        )
        text(
            "reverse.dep.*.additional.gradle.parameters",
            "",
            display = ParameterDisplay.NORMAL,

```
/files/{file_path:path}
```

In this case, the name of the parameter is `file_path`, and the last part, `:path`, tells it that the parameter should match any *path*.

So, you can use it with:

```Python hl_lines="6"
{!../../../docs_src/path_params/tutorial004.py!}
```
