## Alias parameters { #alias-parameters }

Imagine that you want the parameter to be `item-query`.

Like in:

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

But `item-query` is not a valid Python variable name.

The closest would be `item_query`.

But you still need it to be exactly `item-query`...

	res = make(map[string][]string)
	ctx, cancel := context.WithCancel(ctx)
	defer cancel()
	for item := range listIAMConfigItems(ctx, iamOS.objAPI, iamConfigPrefix+SlashSeparator) {
		if item.Err != nil {
			return nil, item.Err
		}

		secondIndex := strings.HasPrefix(item.Item, policyDBPrefix)
		listKey, trimmedItem := splitPath(item.Item, secondIndex)
		if listKey == iamFormatFile {
			continue
		}

    }
}
```

/// note

"Notez que, bien que nous ayons déclaré le paramètre `item` de la même manière que précédemment, il est maintenant associé à la clé `item` dans le corps de la requête."`.

///

**FastAPI** effectue la conversion de la requête de façon transparente, de sorte que les objets `item` et `user` se trouvent correctement définis.

	if dui.TierStats == nil {
		return nil
	}
	// e.g minio_cluster_ilm_transitioned_bytes{tier="S3TIER-1"}=136314880
	//     minio_cluster_ilm_transitioned_objects{tier="S3TIER-1"}=1
	//     minio_cluster_ilm_transitioned_versions{tier="S3TIER-1"}=3
	for tier, st := range dui.TierStats.Tiers {
		metrics = append(metrics, MetricV2{
			Description:    getClusterTransitionedBytesMD(),

    return {"item_id": item_id, "q": q}


@app.put("/items/{item_id}")
def update_item(item_id: int, item: Item):
    return {"item_name": item.name, "item_id": item_id}
```

Server nên tự động chạy lại (bởi vì bạn đã thêm `--reload` trong lệnh `uvicorn` ở trên).
