## 多次使用不同的 `prefix` 包含同一个路由器

你也可以在*同一*路由器上使用不同的前缀来多次使用 `.include_router()`。

在有些场景这可能有用，例如以不同的前缀公开同一个的 API，比方说 `/api/v1` 和 `/api/latest`。

这是一个你可能并不真正需要的高级用法，但万一你有需要了就能够用上。

## 在另一个 `APIRouter` 中包含一个 `APIRouter`

与在 `FastAPI` 应用程序中包含 `APIRouter` 的方式相同，你也可以在另一个 `APIRouter` 中包含 `APIRouter`，通过：

```Python

)

//msgp:clearomitted

//go:generate msgp -file $GOFILE -unexported

// dataUsageHash is the hash type used.
type dataUsageHash string

// sizeHistogramV1 is size histogram V1, which has fewer intervals esp. between
// 1024B and 1MiB.
type sizeHistogramV1 [dataUsageBucketLenV1]uint64

// sizeHistogram is a size histogram.
type sizeHistogram [dataUsageBucketLen]uint64

		g1.Status != g2.Status ||
		g1.Policy != g2.Policy {
		return false
	}
	if len(g1.Members) != len(g2.Members) {
		return false
	}
	for _, v1 := range g1.Members {
		var found bool
		if slices.Contains(g2.Members, v1) {
			found = true
		}
		if !found {
			return false
		}
	}
	return true
}

func isUserInfoEqual(u1, u2 madmin.UserInfo) bool {

		a.Scale = int16(scale)
	}
}

// registerList parses an ARM or ARM64 register list expression, a list of
// registers in []. There may be comma-separated ranges or individual
// registers, as in [R1,R3-R5] or [V1.S4, V2.S4, V3.S4, V4.S4].
// For ARM, only R0 through R15 may appear.
// For ARM64, V0 through V31 with arrangement may appear.
//
// For 386/AMD64 register list specifies 4VNNIW-style multi-source operand.

            )
            response_name = "Response_" + self.unique_id
            if annotation_is_pydantic_v1(self.response_model):
                raise PydanticV1NotSupportedError(
                    "pydantic.v1 models are no longer supported by FastAPI."
                    f" Please update the response model {self.response_model!r}."
                )
            self.response_field = create_model_field(

                **Example**

                ```python
                from fastapi import FastAPI

                app = FastAPI(openapi_url="/api/v1/openapi.json")
                ```
                """
            ),
        ] = "/openapi.json",
        openapi_tags: Annotated[
            Optional[list[dict[str, Any]]],
            Doc(

with the precision of that type argument. For example, given the function:
</p>

<pre>
func dotProduct[F ~float32|~float64](v1, v2 []F) F {
	var s F
	for i, x := range v1 {
		y := v2[i]
		s += x * y
	}
	return s
}
</pre>

<p>
the product <code>x * y</code> and the addition <code>s += x * y</code>

	batchReplVersion      = batchReplVersionV1
	batchJobName          = "job.bin"
	batchJobPrefix        = "batch-jobs"
	batchJobReportsPrefix = batchJobPrefix + "/reports"

	batchReplJobAPIVersion        = "v1"
	batchReplJobDefaultRetries    = 3
	batchReplJobDefaultRetryDelay = time.Second
)

func getJobPath(job BatchJobRequest) string {
	return pathJoin(batchJobPrefix, job.ID)
}
