错误码
错误码格式
当用户访问API出现错误时，会返回给用户相应的错误码和错误信息，便于定位问题，并做出适当的处理。请求发生错误时通过Response Body返回详细错误信息，遵循如下格式：
| 参数名 | 类型 | 说明 |
|---|---|---|
| code | String | 错误码 |
| message | String | 错误描述 |
| requestId | String | 本次请求的requestId |
例如：
{
"requestId" : "ae2225f7-1c2e-427a-a1ad-5413b762957d",
"code" : "NoSuchKey",
"message" : "The resource you requested does not exist"
