{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[5:10,16,21] title["app/routers/items.py"] *}

由于每个*路径操作*的路径都必须以 `/` 开头，例如：

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...前缀不能以 `/` 作为结尾。

因此，本例中的前缀为 `/items`。

我们还可以添加一个 `tags` 列表和额外的 `responses` 列表，这些参数将应用于此路由器中包含的所有*路径操作*。

	switch word {
	case "TEXT":
		// Defines text symbol in operands[0].
		if len(operands) > 0 {
			p.start(operands[0])
			if name, abi, ok := p.funcAddress(); ok {
				fmt.Fprintf(w, "def %s %s\n", name, abi)
			}
		}
		return
	case "GLOBL", "PCDATA":
		// No text definitions or symbol references.
	case "DATA", "FUNCDATA":
		// For DATA, operands[0] is defined symbol.

    assertFailsWith<IOException> {
      sink2.writeUtf8("abc")
      sink2.flush()
    }.also { expected ->
      assertThat(expected.message).isEqualTo("stream was reset: REFUSED_STREAM")
    }
    sink1.writeUtf8("def")
    sink1.close()
    assertFailsWith<ConnectionShutdownException> {
      connection.newStream(headerEntries("c", "cola"), true)
    }
    assertThat(stream1.isOpen).isTrue()

```Python
response = requests.get("http://example.com/some/url")
```

이에 대응하는 FastAPI의 API *경로 처리*는 다음과 같이 보일 수 있습니다:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

`requests.get(...)`와 `@app.get(...)`의 유사성을 확인해 보세요.

/// check | **FastAPI**에 영감을 준 것

* 단순하고 직관적인 API를 갖기.

用法非常簡單。例如，發出一個 `GET` 請求，你會寫：

```Python
response = requests.get("http://example.com/some/url")
```

相對地，FastAPI 的 API 路徑操作（path operation）可能像這樣：

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

看看 `requests.get(...)` 與 `@app.get(...)` 的相似之處。

/// check | 啟發 **FastAPI**

* 擁有簡單直觀的 API。
* 直接使用 HTTP 方法名稱（操作），以直接、直觀的方式表達。

    val k1Creator = cache.edit("k1")!!

    k2Creator.setString(1, "G")
    k2Creator.commit()
    val k1Snapshot = cache["k1"]!!
    k1Snapshot.close()
    cache.close()

  // Export to a graph def so we can import a graph with control dependencies
  TF_DeleteBuffer(graph_def);

各 *path operation* のパスは次のように `/` で始める必要があるため:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...prefix の末尾に `/` を含めてはいけません。

この場合の prefix は `/items` です。

また、`tags` のリストや追加の `responses` を、このルーターに含まれるすべての *path operations* に適用するよう追加できます。
