用与上一章同样的方式实现应用授权。

使用如下凭证：

用户名: `johndoe` 密码: `secret`

/// check | 检查

注意，代码中没有明文密码**`secret`**，只保存了它的哈希值。

调用 `/users/me/` 端点，收到下面的响应：

```JSON
{
  "username": "johndoe",

   </ResponseMetadata>
</AssumeRoleWithCertificateResponse>
```

## Authentication Flow

A client can request temp. S3 credentials via the STS API. It can authenticate via a client certificate and obtain a access/secret key pair as well as a session token. These credentials are associated to an S3 policy at the MinIO server.

		// Retrieve the credential's claims.
		secret, err := getTokenSigningKey()
		if err != nil {
			c.Fatalf("Error getting token signing key: %v", err)
		}
		claims, err := getClaimsFromTokenWithSecret(value.SessionToken, secret)
		if err != nil {
			c.Fatalf("Error getting claims from token: %v", err)
		}

		// Validate claims.

                            },

                        "required": ["name", "secret_name"],
                        "title": "Hero",
                    },
