## Zugriff auf den Requestbody in einem Exceptionhandler

/// tip | Tipp

Um dasselbe Problem zu lösen, ist es wahrscheinlich viel einfacher, den `body` in einem benutzerdefinierten Handler für `RequestValidationError` zu verwenden ([Fehlerbehandlung](../tutorial/handling-errors.md#den-requestvalidationerror-body-verwenden){.internal-link target=_blank}).

    return if (cookies != null) {
      Collections.unmodifiableList(cookies)
    } else {
      emptyList()
    }
  }

  /**
   * Convert a request header to OkHttp's cookies via [HttpCookie]. That extra step handles
   * multiple cookies in a single request header, which [Cookie.parse] doesn't support.
   */
  private fun decodeHeaderAsJavaNetCookies(
    url: HttpUrl,
    header: String,
  ): List<Cookie> {

            // Assert
            assertEquals(0, written, "Should report 0 bytes written");
            assertArrayEquals(original, buffer, "Buffer must remain unchanged");
        }

        @Test
        @DisplayName("Handles null destination without throwing and returns 0")
        void allowsNullBuffer() {
            // Arrange
            Smb2LogoffResponse resp = newResponse();

            // Act & Assert
