Again, it will convert the data types, validate, document, etc.

## Multiple body params and query

Of course, you can also declare additional query parameters whenever you need, additional to any body parameters.

    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

* Editor support (completion, etc.), even for nested models
* Data conversion
* Data validation
* Automatic documentation

## Special types and validation

	}

	// Parse address to extract host and scheme field
	u, err := url.Parse(hostAddr)
	if err != nil {
		return "", "", err
	}

	addr = u.Host
	scheme = u.Scheme

	// Use the given parameter again if url.Parse()
	// didn't return any useful result.
	if addr == "" {
		addr = hostAddr
		scheme = "http"
	}

	// At this point, addr can be one of the following form:
	//	":9000"
	//	"localhost:9000"

### Generate a TypeScript Client with Custom Operation IDs

Now if you generate the client again, you will see that it has the improved method names:

<img src="/img/tutorial/generate-clients/image07.png">

	// sets the bucket policy using the policy statement generated from `getWriteOnlyObjectStatement` so that the
	// unsigned request goes through and its validated again.
	ExecObjectLayerAPIAnonTest(t, obj, "PutBucketPolicyHandler", bucketName, "", instanceType, apiRouter, anonReq, getAnonWriteOnlyBucketPolicy(bucketName))

	// HTTP request for testing when `objectLayer` is set to `nil`.

				}
				if len(incorrectConfigs) > 0 {
					logger.Info(fmt.Sprintf("Following servers have mismatching configuration %s", incorrectConfigs))
				}
				retries = 0 // reset to log again after 20 retries.
			}
			offlineEndpoints = nil
			incorrectConfigs = nil
		}
	}
	return nil
}

## Soft delete (creates delete markers)
./mc rm -r --force myminio/versioned >/dev/null
./mc rm -r --force myminio/versioned-1 >/dev/null

## mirror again to create another set of version on top

```Python
commons: CommonQueryParams = Depends()
```

////

You declare the dependency as the type of the parameter, and you use `Depends()` without any parameter, instead of having to write the full class *again* inside of `Depends(CommonQueryParams)`.

The same example would then look like:
