## Özet

**FastAPI** ile kısa, sezgisel ve standart Python tip tanımlamaları kullanarak şunları elde edersiniz:

* Editör desteği: hata denetimi, otomatik tamamlama, vb.
* Veri "<abbr title="HTTP isteği ile birlikte gelen string'i Python verisine dönüştürme">dönüştürme</abbr>"
* Veri doğrulama

```Python hl_lines="9"
{!> ../../docs_src/query_params_str_validations/tutorial011.py!}
```

Dann, mit einer URL wie:

```
http://localhost:8000/items/?q=foo&q=bar
```

bekommen Sie alle `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-Liste – `list` – in ihrer *Pfadoperation-Funktion*, im Funktionsparameter `q`, überreicht.

Die Response für diese URL wäre also:

```JSON
{
  "q": [

server["Server auf http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip | "Tipp"

Die IP `0.0.0.0` wird üblicherweise verwendet, um anzudeuten, dass das Programm alle auf diesem Computer/Server verfügbaren IPs abhört.

### Starten

Führen Sie den Server aus:

<div class="termy">

```console

            if (declaration.matchesNameAndIsSince(classSimpleName, version)) true
            else super.visit(declaration, arg)

        override fun visit(declaration: AnnotationDeclaration, arg: Unit?): Boolean? =
            if (declaration.matchesNameAndIsSince(classSimpleName, version)) true
            else super.visit(declaration, arg)

        override fun visit(declaration: EnumDeclaration, arg: Unit?): Boolean? =

    if (cmp < 0) {
      return aggregateBelowRange(aggr, node.left);
    } else if (cmp == 0) {
      switch (range.getLowerBoundType()) {
        case OPEN:
          return aggr.nodeAggregate(node) + aggr.treeAggregate(node.left);
        case CLOSED:
          return aggr.treeAggregate(node.left);
      }
      throw new AssertionError();
    } else {
      return aggr.treeAggregate(node.left)

          logger.log("--> END ${request.method}")
        } else if (bodyHasUnknownEncoding(request.headers)) {
          logger.log("--> END ${request.method} (encoded body omitted)")
        } else if (requestBody.isDuplex()) {
          logger.log("--> END ${request.method} (duplex request body omitted)")
        } else if (requestBody.isOneShot()) {

						primaryFields = append(primaryFields, ref.PrimaryKey)
