Tek yapmamız gereken, request'i bir `try`/`except` bloğu içinde handle etmek:

{* ../../docs_src/custom_request_and_route/tutorial002_an_py310.py hl[14,16] *}

Bir exception oluşursa, `Request` instance'ı hâlâ scope içinde olacağı için, hatayı handle ederken request body'yi okuyup kullanabiliriz:

{* ../../docs_src/custom_request_and_route/tutorial002_an_py310.py hl[17:19] *}

  }

  private static long random() {
    return randomSource.nextLong();
  }

  // A random value that cannot be 0 and that is unsigned-less-than or equal
  // to the given dividend, so that we don't have half of our divisions being
  // trivial because the divisor is bigger than the dividend.
  // Using remainder here does not give us a uniform distribution but it should
  // not have a big impact on the measurement.

FastAPI’de `BackgroundTask`’i tek başına kullanmak hâlâ mümkündür; ancak bu durumda objeyi kendi kodunuzda oluşturmanız ve onu içeren bir Starlette `Response` döndürmeniz gerekir.

Örneğin, bir Pydantic model'i, önce JSON-uyumlu tiplere çevrilmeden (`datetime`, `UUID` vb.) doğrudan bir `JSONResponse` içine koyamazsınız. Önce tüm veri tipleri JSON-uyumlu hale gelecek şekilde `dict`'e çevrilmesi gerekir.

Bu gibi durumlarda, response'a vermeden önce verinizi dönüştürmek için `jsonable_encoder` kullanabilirsiniz:

{* ../../docs_src/response_directly/tutorial001_py310.py hl[5:6,20:21] *}

        // Test that full-width characters are converted to half-width
        List<String> results = converter.convert("アイウ", null);
        for (String result : results) {
            assertFalse(result.contains("Ａ")); // Full-width A

 * The class also utilizes ICU4J's {@link com.ibm.icu.text.Transliterator} to convert full-width characters
 * to half-width and to convert any characters to lowercase, ensuring consistency in the output.

 * Example:
 * For the input "キャ", the converter might return a list containing "kya".
