But when you declare them with Python types (in the example above, as `int`), they are converted to that type and validated against it.

All the same process that applied for path parameters also applies for query parameters:

* Editor support (obviously)
* Data <abbr title="converting the string that comes from an HTTP request into Python data">"parsing"</abbr>
* Data validation
* Automatic documentation

## Defaults

  // RFC-6335 and https://www.iana.org/assignments/service-names).

  // * Kubernetes-defined prefixed names:
  //   * 'kubernetes.io/h2c' - HTTP/2 over cleartext as described in https://www.rfc-editor.org/rfc/rfc7540
  //
  // * Other protocols should use implementation-defined prefixed names such as
  // mycompany.com/my-custom-protocol.
  // +optional

##  **FastAPI** tip belirteçleri

**FastAPI** birkaç şey yapmak için bu tür tip belirteçlerinden faydalanır.

**FastAPI** ile parametre tiplerini bildirirsiniz ve şunları elde edersiniz:

* **Editor desteği**.
* **Tip kontrolü**.

...ve **FastAPI** aynı belirteçleri şunlar için de kullanıyor:

<font color="#4E9A06">INFO</font>:     Application startup complete.
</pre>
```

</div>

It is **HIGHLY encouraged** that you write or copy the code, edit it and run it locally.

Using it in your editor is what really shows you the benefits of FastAPI, seeing how little code you have to write, all the type checks, autocompletion, etc.

---

## Install FastAPI

The first step is to install FastAPI:

    # XXX: if you enable this setting, unparam will report a lot of false-positives in text editors:
    # if it's called for subdir of a project it can't find external interfaces. All text editor integrations
    # with golangci-lint call it on a directory with the changed file.
    check-exported: false
  gci:
    sections:

IMG="${IMG:-${TOOLS_REGISTRY_PROVIDER}/${PROJECT_ID}/${IMAGE_NAME}:${IMAGE_VERSION}}"

CONTAINER_CLI="${CONTAINER_CLI:-docker}"

ENV_BLOCKLIST="${ENV_BLOCKLIST:-^_\|^PATH=\|^GOPATH=\|^GOROOT=\|^SHELL=\|^EDITOR=\|^TMUX=\|^USER=\|^HOME=\|^PWD=\|^TERM=\|^RUBY_\|^GEM_\|^rvm_\|^SSH=\|^TMPDIR=\|^CC=\|^CXX=\|^MAKEFILE_LIST=}"

# Remove functions from the list of exported variables, they mess up with the `env` command.

        Prefer to use the `Annotated` version if possible.

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial003.py!}
    ```

But declaring the type is encouraged as that way your editor will know what will be passed as the parameter `commons`, and then it can help you with code completion, type checks, etc:

## Shortcut

Die Abhängigkeiten funktionieren weiterhin wie erwartet, und das **Beste daran** ist, dass die **Typinformationen erhalten bleiben**, was bedeutet, dass Ihr Editor Ihnen weiterhin **automatische Vervollständigung**, **Inline-Fehler**, usw. bieten kann. Das Gleiche gilt für andere Tools wie `mypy`.

        Bevorzugen Sie die `Annotated`-Version, falls möglich.

    ```Python hl_lines="19"
    {!> ../../../docs_src/dependencies/tutorial003.py!}
    ```

Es wird jedoch empfohlen, den Typ zu deklarieren, da Ihr Editor so weiß, was als Parameter `commons` übergeben wird, und Ihnen dann bei der Codevervollständigung, Typprüfungen, usw. helfen kann:
