以下のような感じです:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

しかし、`item-query`は有効なPythonの変数名ではありません。

最も近いのは`item_query`でしょう。

しかし、どうしても`item-query`と正確に一致している必要があるとします...

それならば、`alias`を宣言することができます。エイリアスはパラメータの値を見つけるのに使用されます:

```Python hl_lines="9"
{!../../docs_src/query_params_str_validations/tutorial009.py!}
```

## 非推奨パラメータ

さて、このパラメータが気に入らなくなったとしましょう

alias(
    name = "is_cuda_enabled",
    actual = if_oss(
        "@local_config_cuda//:is_cuda_enabled",
        "@local_config_cuda//cuda:using_config_cuda",
    ),
)

# Config setting that is satisfied when CUDA device code should be compiled
# with clang. It does not imply that CUDA support has been enabled.
alias(
    name = "is_cuda_compiler_clang",

pkg encoding/csv, type Reader struct, ReuseRecord bool
pkg encoding/json, func Valid([]uint8) bool
pkg go/ast, type TypeSpec struct, Assign token.Pos

## Create a bucket and upload some data

Create a bucket named `functionbucket`
```
mc alias set myminio/ http://localhost:9000 minioadmin minioadmin
mc mb myminio/functionbucket
```

Create a file `testobject` with some test data that will be transformed
```
cat > testobject << EOF
