### Errors

XML error response for this API is similar to [AWS STS AssumeRoleWithWebIdentity](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html#API_AssumeRoleWithWebIdentity_Errors)

## Sample `POST` Request

```
http://minio.cluster:9000?Action=AssumeRoleWithLDAPIdentity&LDAPUsername=foouser&LDAPPassword=foouserpassword&Version=2011-06-15&DurationSeconds=7200
```

## Sample Response

```

// Returns a storage rest client.
func newStorageRESTClient(endpoint Endpoint, healthCheck bool, gm *grid.Manager) (*storageRESTClient, error) {
	serverURL := &url.URL{
		Scheme: endpoint.Scheme,
		Host:   endpoint.Host,
		Path:   path.Join(storageRESTPrefix, endpoint.Path, storageRESTVersion),
	}

	restClient := rest.NewClient(serverURL, globalInternodeTransport, newCachedAuthToken())
	if healthCheck {

在這些情況下，你可以使用「路徑操作裝飾器」參數 `response_model`，而不是函式的回傳型別。

你可以在任何「路徑操作」上使用 `response_model` 參數：

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 等等。

{* ../../docs_src/response_model/tutorial001_py310.py hl[17,22,24:27] *}

/// note | 注意

注意 `response_model` 是「裝飾器」方法（`get`、`post` 等）的參數。不是你的「路徑操作函式」的參數（像其他參數與請求主體那樣）。
