rds： SDK 报错， 服务端返回值的层次结构与SDK的struct不一致

[wanglong001]

调用了rds这个接口

// DescribeAvailableZones invokes the rds.DescribeAvailableZones API synchronously
func (client *Client) DescribeAvailableZones(request *DescribeAvailableZonesRequest) (response *DescribeAvailableZonesResponse, err error) {
	response = CreateDescribeAvailableZonesResponse()
	err = client.DoAction(request, response)
	return
}

返回报错：

Failed to unmarshal response, but you can get the data via response.GetHttpStatusCode() and response.GetHttpContentString()

有数据返回，但是解析数据时报错

type DescribeAvailableZonesResponse struct {
	*responses.BaseResponse
	RequestId      string          `json:"RequestId" xml:"RequestId"`
	AvailableZones []AvailableZone `json:"AvailableZones" xml:"AvailableZones"`
}

type AvailableZone struct {
	RegionId         string                                      `json:"RegionId" xml:"RegionId"`
	ZoneId           string                                      `json:"ZoneId" xml:"ZoneId"`
	Status           string                                      `json:"Status" xml:"Status"`
	NetworkTypes     string                                      `json:"NetworkTypes" xml:"NetworkTypes"`
	SupportedEngines SupportedEnginesInDescribeAvailableResource `json:"SupportedEngines" xml:"SupportedEngines"`
}

type SupportedEnginesInDescribeAvailableResource struct {
	SupportedEngine []SupportedEngineInDescribeAvailableResource `json:"SupportedEngine" xml:"SupportedEngine"`
}

type SupportedEngineInDescribeAvailableResource struct {
	Engine                  string                                             `json:"Engine" xml:"Engine"`
	SupportedEngineVersions SupportedEngineVersionsInDescribeAvailableResource `json:"SupportedEngineVersions" xml:"SupportedEngineVersions"`
}

理论上json应该得这样

SupportedEngines : {SupportedEngine:[{"SupportedEngineVersions": xxx}]}

我同样的问题，在k8s内报错，直接build的没问题
