### 可选文档升级

访问 <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>。

* 可选文档同样会体现新加入的请求参数和请求体：

            }
            // If failure rate is moderate but response time is very high, be stricter

          // pause slightly after half way to make result more predictable
          Thread.sleep(100)
        }
      } catch (e: IOException) {
        break
      }
      i++
    }
    // Halfway +/- 0.5%
    assertThat(i.toFloat()).isCloseTo(512f, 5f)
  }

  @Test
  fun disconnectResponseHalfway() {
    server.enqueue(

        .Builder()
        .body("ab")

**FastAPI**'ın header ve çerez tanımlamak için fonksiyonlarda `response` parametresini belirtmesinde de Hug'dan ilham alındı.

**FastAPI**'ı geliştirmeye başlamadan hemen önce **APIStar** sunucusunu buldum. Benim aradığım şeylerin neredeyse hepsine sahipti ve harika bir tasarımı vardı.

* Şimdi "Execute" butonuna tıklayalım, kullanıcı arayüzü API'ımız ile bağlantı kurup parametreleri gönderecek ve sonucu ekranımıza getirecek:
