Örneğin, aşağıdaki bağlantıda:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...sorgu parametreleri şunlardır:

* `skip`: değeri `0`'dır
* `limit`: değeri `10`'dır

Parametreler bağlantının bir parçası oldukları için doğal olarak string olarak değerlendirilirler.

    def __init__(self, q: str | None = None, skip: int = 0, limit: int = 100):
        self.q = q
        self.skip = skip
        self.limit = limit


@app.get("/items/")
async def read_items(commons: Annotated[Any, Depends(CommonQueryParams)]):
    response = {}
    if commons.q:
        response.update({"q": commons.q})
    items = fake_items_db[commons.skip : commons.skip + commons.limit]
    response.update({"items": items})

from fastapi import FastAPI

app = FastAPI()

fake_items_db = [{"item_name": "Foo"}, {"item_name": "Bar"}, {"item_name": "Baz"}]


@app.get("/items/")
async def read_item(skip: int = 0, limit: int = 10):

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/{item_id}")
async def read_user_item(
    item_id: str, needy: str, skip: int = 0, limit: Union[int, None] = None
):
    item = {"item_id": item_id, "needy": needy, "skip": skip, "limit": limit}

      input: String,
      pos: Int,
      limit: Int,
    ): Int {
      var i = pos
      while (i < limit) {
        when (input[i]) {
          '[' -> {
            while (++i < limit) {
              if (input[i] == ']') break
            }
          }
          ':' -> return i
        }
        i++
      }
      return limit // No colon.
    }

Zum Beispiel sind in der URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

... die Query-Parameter:

* `skip`: mit dem Wert `0`
* `limit`: mit dem Wert `10`

Da sie Teil der URL sind, sind sie „naturgemäß“ Strings.
