## 多次使用同一個相依項 { #using-the-same-dependency-multiple-times }

如果你的某個相依項在同一個路徑操作中被宣告了多次，例如多個相依共用同一個子相依，**FastAPI** 會知道只需在每次請求中呼叫該子相依一次。

它會把回傳值儲存在一個 <dfn title="用來儲存已計算/產生之值的工具／系統，以便重複使用而不必再次計算。">「快取」</dfn> 中，並在該次請求中傳遞給所有需要它的「相依者」，而不是為同一個請求多次呼叫相同的相依項。

## 同じ依存関係の複数回の使用 { #using-the-same-dependency-multiple-times }

依存関係の1つが同じ*path operation*に対して複数回宣言されている場合、例えば、複数の依存関係が共通のサブ依存関係を持っている場合、**FastAPI** はリクエストごとに1回だけそのサブ依存関係を呼び出します。

        int expected =
            force32(aUnsigned.bigIntegerValue().multiply(bUnsigned.bigIntegerValue()).intValue());
        UnsignedInteger unsignedMul = aUnsigned.times(bUnsigned);
        assertWithMessage("%s * %s", aUnsigned, bUnsigned)
            .that(unsignedMul.intValue())
            .isEqualTo(expected);
      }
    }
  }

  * Renamed Kubelet metric certificate_manager_server_expiration_seconds to certificate_manager_server_ttl_seconds and changed to report the second until expiration at read time rather than absolute time of expiry. 
  * Improved accuracy of Kubelet metric rest_client_exec_plugin_ttl_seconds.

- Fixed the reporting of elapsed times during evaluation of `ValidatingAdmissionPolicy` decisions and annotations. The apiserver_validating_admission_policy_check_duration metrics will now show elapsed times and no longer be zero.
