旧输出参数cli-output-rows,cli-output-cols,cli-output-num如何使用?
通过KooCLI调用云服务API,默认会返回json格式的调用结果。KooCLI支持使用“--cli-output-rows”,“--cli-output-cols”,“--cli-output-num”参数,以table格式输出,方便提炼调用结果中的关键信息,如下:
hcloud ECS NovaListServers --cli-region="cn-north-4" --project_id="0dd8cb****************19b5a84546" { "servers": [ { "name": "ecs-a6b4", "links": [ { "rel": "self", "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/4f06****-****-****-****-****04dd856a" }, { "rel": "bookmark", "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/4f06****-****-****-****-****04dd856a" } ], "id": "4f06****-****-****-****-****04dd856a" }, { "name": "hdn-docker", "links": [ { "rel": "self", "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/6731****-****-****-****-****0bc463f0" }, { "rel": "bookmark", "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/6731****-****-****-****-****0bc463f0" } ], "id": "6731****-****-****-****-****0bc463f0" }, { "name": "ecs-8f88", "links": [ { "rel": "self", "href": "https://ecs.cn-north-4.myhuaweicloud.com/v2.1/0dd8cb****************19b5a84546/servers/06a2****-****-****-****-****c79a1a26" }, { "rel": "bookmark", "href": "https://ecs.cn-north-4.myhuaweicloud.com/0dd8cb****************19b5a84546/servers/06a2****-****-****-****-****c79a1a26" } ], "id": "06a2****-****-****-****-****c79a1a26" } ] }
以table输出调用结果时,“--cli-output-rows”指定json结构体的层级,即表格的数据来源;“--cli-output-cols”指定表格的列名,需要与json结构体中的字段相对应;“--cli-output-num”指定是否打印表格行号,默认值为true,如下图所示:
hcloud ECS NovaListServers --cli-region="cn-north-4" --project_id="0dd8cb******************b5a84546" --cli-output-rows="servers" --cli-output-cols="name,id"
使用“--cli-output-rows”,“--cli-output-cols”,“--cli-output-num”参数也可以用于系统命令中,如下所示:
hcloud configure list --cli-output-rows="profiles[]"
hcloud configure list --cli-output-rows="profiles[0]" --cli-output-cols="name,accessKeyId,secretAccessKey,projectId,region"
使用“--cli-output-rows”,“--cli-output-cols”,“--cli-output-num”进行table输出时的其他注意事项如下所示。
