调用阿里云API 的demo示例（java/python）

Java 示例

// 创建DefaultAcsClient实例并初始化
        DefaultProfile profile = DefaultProfile.getProfile(vo.getAliRegionId(),AliAccessKeyId,AliAccessKeySecret);
        IAcsClient client = new DefaultAcsClient(profile);

        // 创建API请求并设置参数
        DescribeVirtualBorderRoutersRequest request = new DescribeVirtualBorderRoutersRequest();

        //组装filter数据
        List<DescribeVirtualBorderRoutersRequest.Filter> list = new ArrayList<DescribeVirtualBorderRoutersRequest.Filter>();
        DescribeVirtualBorderRoutersRequest.Filter filter = new DescribeVirtualBorderRoutersRequest.Filter();
        filter.setKey(AliEdgeRouterConstant.FILTER_KEY);
        List list1 = new ArrayList();
        list1.add(vo.getVbrUuid());
        filter.setValues(list1);
        list.add(filter);

        request.setFilters(list);

        DescribeVirtualBorderRoutersResponse response ;
        try{
            response = client.getAcsResponse(request);

            DescribeVirtualBorderRoutersResponse.VirtualBorderRouterType virtualBorderRouterType = new DescribeVirtualBorderRoutersResponse.VirtualBorderRouterType();
            virtualBorderRouterType = response.getVirtualBorderRouterSet().get(0);

            routerInventory.setName(virtualBorderRouterType.getName());
            routerInventory.setVbrUuid(virtualBorderRouterType.getVbrId());
            routerInventory.setDescription(virtualBorderRouterType.getDescription());
            routerInventory.setCreateDate(vo.getCreateDate());
            routerInventory.setVlan(vo.getVlan());
            routerInventory.setAliAccountUuid(vo.getAliAccountUuid());
            routerInventory.setAliRegionId(vo.getAliRegionId());

            inventory.setAccessPoint(virtualBorderRouterType.getAccessPointId());
            inventory.setStatus(virtualBorderRouterType.getStatus());
            inventory.setPhysicalLineOwerUuid(virtualBorderRouterType.getPhysicalConnectionOwnerUid());
            inventory.setLocalGatewayIp(virtualBorderRouterType.getLocalGatewayIp());
            inventory.setPeerGatewayIp(virtualBorderRouterType.getPeerGatewayIp());
            inventory.setPeeringSubnetMask(virtualBorderRouterType.getPeeringSubnetMask());

        }catch (ClientException e){
            e.printStackTrace();
            if(e.getErrCode().equals("InvalidAccessKeyId.NotFound")){
                flag = false;
            }else{
                throw new ApiMessageInterceptionException(argerr(e.getMessage()));
            }

        }

　　Python示例

sdk:

def ModifyVirtualBorderRouterAttribute(key, value, RegionId, VBRId, LocalGatewayIp, PeerGatewayIp, PeeringSubnetMask, Name, Description):

    from aliyunsdkvpc.request.v20160428 import ModifyVirtualBorderRouterAttributeRequest
    request = ModifyVirtualBorderRouterAttributeRequest.ModifyVirtualBorderRouterAttributeRequest()
    request.set_accept_format('json')
    request.set_VbrId(VBRId)
    request.set_LocalGatewayIp(LocalGatewayIp)
    request.set_PeerGatewayIp(PeerGatewayIp)
    request.set_PeeringSubnetMask(PeeringSubnetMask)
    request.set_Name(Name)
    request.set_Description(Description)
    client.set_access_key(key)
    client.set_access_secret(value)
    client.set_region_id(RegionId)

    reponse = client.do_action_with_exception(request)
    return reponse
