    我们将`SessionLocal()`请求的创建和处理放在一个`try`块中。

    然后我们在finally块中关闭它。

    通过这种方式，我们确保数据库会话在请求后始终关闭。即使在处理请求时出现异常。

    但是您不能从退出代码中引发另一个异常（在yield之后）。可以查阅 [Dependencies with yield and HTTPException](https://fastapi.tiangolo.com/zh/tutorial/dependencies/dependencies-with-yield/#dependencies-with-yield-and-httpexception)

*然后，当在路径操作函数*中使用依赖项时，我们使用`Session`，直接从 SQLAlchemy 导入的类型声明它。

*这将为我们在路径操作函数*中提供更好的编辑器支持，因为编辑器将知道`db`参数的类型`Session`：

					if b['tophash'][i] != 0:
						k = b['keys'][i]
						v = b['values'][i]
						if flags & 1:
							k = k.dereference()
						if flags & 2:
							v = v.dereference()
						yield str(cnt), k
						yield str(cnt + 1), v
						cnt += 2
				bp = b['overflow']

will use arguments n+1, n+2, etc. unless otherwise directed.

For example,

	fmt.Sprintf("%[2]d %[1]d\n", 11, 22)

will yield "22 11", while

	fmt.Sprintf("%[3]*.[2]*[1]f", 12.0, 2, 6)

equivalent to

	fmt.Sprintf("%6.2f", 12.0)

will yield " 12.00". Because an explicit index affects subsequent verbs,
this notation can be used to print the same values multiple times
