NetWorker : Comment rendre lisible par l’utilisateur la réponse JSON de l’API REST de ligne de commande
Summary: Les réponses de l’API (Application Programming Interface) REST en ligne de commande sont au format JSON non formaté, qui peut être difficile à analyser. Cet article de la base de connaissances fournit des méthodes pour formater la réponse de l’API REST en sortie « lisible par l’utilisateur ». ...
Instructions
Les appels d’API REST (NetWorker Representational State Transfer) peuvent être exécutés à partir de la ligne de commande sur un serveur NetWorker Linux à l’aide de curl . Par exemple :
curl -k -u USERNAME:'PASSWORD' https://localhost:9090/nwrestapi/v3/global/RESTAPI-ENDPOINT
La charge utile de réponse d’une opération GET est au format JSON. La réponse par défaut peut être difficile à analyser, car il s’agit généralement d’une ligne continue. Par exemple :
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global

La sortie JSON n’est pas formatée et peut être difficile à analyser. Cependant, la sortie peut être formatée dans un format plus facile à lire « joli imprimé ».
Pour les systèmes NetWorker Virtual Edition (NVE), vous pouvez ajouter python -m json.tool à l curl . Par exemple :
nve:~ # curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | python -m json.tool

Pour les autres systèmes Linux, cela peut être réalisé en ajoutant jq à l curl WMIC suivante :
[root@nsr ~]# curl -k -u Administrator:'!Password1' https://localhost:9090/nwrestapi/v3/global | jq

jq n’est pas inclus avec NetWorker. Il s’agit d’un utilitaire tiers qui peut être installé sur le système. Consultez l’administrateur système pour installer jq ou d’autres utilitaires de formatage JSON comme vous le souhaitez.
Pour les hôtes Windows , il est peu probable qu’il utilise la ligne de commande pour y parvenir. Cette opération s’effectue généralement via PowerShell, ce qui nécessite des fonctions supplémentaires, impliquant souvent la rédaction de scripts. La plupart des systèmes Windows utilisent une interface utilisateur telle que Post-Man pour formater les demandes GET de l’API REST.
