NetWorker. Как сделать ответ JSON в командной строке REST API удобочитаемым
Summary: Ответы интерфейса прикладного программирования (API) командной строки REST представлены в неформатированном формате JSON, что может быть затруднительно для анализа. В этой статье базы знаний представлены методы для форматирования ответа API REST в «удобочитаемые» выходные данные. ...
Instructions
Вызовы API REST (Representational State Transfer) NetWorker можно выполнять из командной строки на сервере Linux NetWorker с помощью команды curl . Пример.
curl -k -u USERNAME:'PASSWORD' https://localhost:9090/nwrestapi/v3/global/RESTAPI-ENDPOINT
Полезные данные отклика на операцию GET представлены в формате JSON. Ответ по умолчанию может быть сложным для анализа, поскольку обычно это одна непрерывная строка. Пример.
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global

Выходные данные JSON не отформатированы, и их может быть трудно проанализировать; Тем не менее, вывод может быть отформатирован в более удобный для чтения формат «красивой печати».
Для систем NetWorker Virtual Edition (NVE) можно добавить python -m json.tool к curl . Пример.
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | python -m json.tool

Для других систем Linux этого можно достичь, добавив jq к curl :
[root@nsr ~]# curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | jq

jq не входит в состав NetWorker, это сторонняя утилита, которую можно установить в системе. Проконсультируйтесь с системным администратором по установке jq или другие утилиты форматирования JSON по желанию.
На хостах Windows для этого вряд ли будет использоваться командная строка. Обычно это делается с помощью PowerShell, для чего требуются дополнительные функции, часто включающие сценарии. Большинство систем на базе Windows используют пользовательский интерфейс, например Post-Man, для форматирования запросов GET API-интерфейса REST.
