NetWorker: Jak sprawić, by odpowiedź JSON interfejsu API REST wiersza poleceń była czytelna dla człowieka
Summary: Odpowiedzi interfejsu programowania aplikacji (API) REST w wierszu polecenia są w niesformatowanym formacie JSON, który może być trudny do przeanalizowania. Ten artykuł bazy wiedzy zawiera metody formatowania odpowiedzi interfejsu API REST na dane wyjściowe "czytelne dla człowieka". ...
Instructions
Wywołania interfejsu API REST (Representational State Transfer) NetWorker można wykonywać z wiersza poleceń na serwerze Linux NetWorker przy użyciu curl . Na przykład:
curl -k -u USERNAME:'PASSWORD' https://localhost:9090/nwrestapi/v3/global/RESTAPI-ENDPOINT
Ładunek odpowiedzi w operacji GET jest w formacie JSON. Domyślna odpowiedź może być trudna do przeanalizowania, ponieważ zwykle jest to jedna linia ciągła. Na przykład:
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global

Dane wyjściowe JSON są niesformatowane i mogą być trudne do przeanalizowania; Jednak dane wyjściowe można sformatować do łatwiejszego do odczytania formatu
"ładny druk".W przypadku systemów NetWorker Virtual Edition (NVE) można dodać python -m json.tool do curl . Na przykład:
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | python -m json.tool

W przypadku innych systemów Linux można to osiągnąć, dodając jq do curl :
[root@nsr ~]# curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | jq

jq nie jest dołączony do NetWorker, jest to narzędzie innej firmy, które można zainstalować w systemie. Skonsultuj się z administratorem systemu w celu instalacji jq lub inne narzędzia do formatowania JSON, jak chcesz.
W przypadku hostów z systemem Windows jest mało prawdopodobne, aby w tym celu używany był wiersz poleceń. Zazwyczaj odbywa się to za pomocą programu PowerShell, który wymaga dodatkowych funkcji, często obejmujących skrypty. Większość systemów z systemem Windows używa interfejsu użytkownika, takiego jak Post-Man, do formatowania żądań REST API GET.
