All Recipient's rights under this Agreement shall terminate if it

Agreement and does not cure such failure in a reasonable period of

/// note | 技術細節

你也可以使用 `from starlette.requests import Request`。

**FastAPI** 為了方便開發者而提供了它，但實際上它直接來自 Starlette。

///

### 在 `response` 之前與之後 { #before-and-after-the-response }

你可以在任何*路徑操作*接收 `request` 之前，加入要執行的程式碼。

也可以在產生出 `response` 之後、回傳之前執行程式碼。

例如，你可以新增一個自訂標頭 `X-Process-Time`，其內容為處理請求並產生回應所花費的秒數：

{* ../../docs_src/middleware/tutorial001_py310.py hl[10,12:13] *}

loating > .form-control:not(:-moz-placeholder-shown) ~ label::after {\n  position: absolute;\n  inset: 1rem 0.375rem;\n  z-index: -1;\n  height: 1.5em;\n  content: \"\";\n  background-color: var(--bs-body-bg);\n  border-radius: var(--bs-border-radius);\n}\n.form-floating > .form-control:focus ~ label::after,\n.form-floating > .form-control:not(:placeholder-shown) ~ label::after,\n.form-floating > .form-control-plaintext ~ label::after,\n.form-floating > .form-select ~ label::after {\n  position:...

 * <p>When iterating through the collections supplied by this class, the ordering of values for a
 * given key agrees with the order in which the values were added.
 *
 * <p>This multimap allows duplicate key-value pairs. After adding a new key-value pair equal to an
 * existing key-value pair, the {@code ArrayListMultimap} will contain entries for both the new
 * value and the old value.

        /**
         * Returns the algorithm end result as string, never {@code null}. After invoking this method, this instance should
         * be discarded and not reused. For new checksum calculation you have to get new instance.
         */
        @Nonnull
        String checksum();
    }

That way, using `secrets.compare_digest()` in your application code, it will be safe against this whole range of security attacks.

### Return the error { #return-the-error }

After detecting that the credentials are incorrect, return an `HTTPException` with a status code 401 (the same returned when no credentials are provided) and add the header `WWW-Authenticate` to make the browser show the login prompt again:

  // Example: If one calls `op->SetDeviceName("/device:GPU")`, the value
  // returned by DeviceName should be "/device:GPU:*" until a particular GPU is
  // chosen for the operation by the device placement logic in the
  // executor. After that, the value returned by DeviceName will be a full
  // device name such as "/job:localhost/replica:0/task:0/device:GPU:1".
  virtual const string& DeviceName() const = 0;

  // Sets the operation device name.
  //
