Obtenir un jeton
Si vous voulez simplement générer un jeton d'accès pour tester une demande d'API, vous pouvez utiliser cet exemple d'application.
Les jetons sont obtenus à partir de l'API Brightcove OAuth. Avant de pouvoir obtenir des jetons d'accès, vous devez d'abord obtenir des informations d'identification client (un identifiant client et un secret client) spécifiques à l'API et aux opérations auxquelles vous souhaitez accéder. Pour obtenir vos informations d'identification client, reportez-vous à la section Gestion des informations d'identification API
Une fois que vous avez vos identifiants, vous obtenez un jeton d'accès en faisant une POST
demande à :
https://oauth.brightcove.com/v4/access_token
Vous devez passer les en-têtes suivants avec cet appel :
Content-Type: application/x-www-form-urlencoded
Authorization: Basic {client_id}:{client_secret}
La {client_id}:{client_secret}
chaîne entière doit être codée en Base64 (curl encode automatiquement la chaîne en Base64-si vous la transmettez comme --user
informations d'identification ; dans d'autres langues, vous devrez gérer l'encodage Base64 vous-même).
Vous devez également envoyer la paire clé/valeur suivante en tant que corps de requête ou paramètre URL :
grant_type=client_credentials
La réponse ressemblera à ceci (jolie-imprimé ici pour plus de lisibilité) :
{
"access_token": "ANB7xKhiUZmwltVd3f1odcHHM9VAwg02kwmLwtZwHv3SxGCOWLUf5W4G7X22PRjmR9StvFUqzpVZ1suOfyfOigdi-rnohxyEaSSuZceeLw_9OBW7fXldOG05HEgkeK3N-DBZZZyilodmjA1JWZHbgI3IU7Rmz5IPGyi-sDxHN3KlOr1BDZlLZpXPdFPwEyb6idq-z8AL-blKTSMtNI3_fz3oNBisfrHGUv5tXHoQT4B7FYcvdrap16gTOO7_wNt1zmgLJiUHvyxZgsgBchm_AhohVL-AYgcfCbCR0v7d2hgI4ag35pnZNeujDiBLfnCFcVMlqQGq8UEVZrmU9a8y4pVAGih_EImmghqmSrkxLPYZ800-vIWX-lw",
"token_type": "Bearer",
"expires_in": 300
}
La access_token
valeur est ce que vous devez passer dans un Authorization
en-tête avec votre appel API sous cette forme :
Authorization: Bearer {access_token}
La expires_in
valeur correspond au nombre de secondes pendant lesquelles le jeton d'accès est valide.
Stratégies d'application
Si votre application effectue uniquement des appels sporadiques aux API Brightcove, vous pouvez aussi bien ignorer le expires_in
paramètre et simplement récupérer un nouveau jeton d'accès pour chaque appel. Dans ce cas, la séquence de traitement ressemblera à ceci :

D'un autre côté, si vous savez que votre application effectuera fréquemment de nombreux appels API en succession rapide (pour, disons, générer des rapports longs), alors il sera plus efficace de récupérer les jetons d'accès uniquement lorsque vous en avez besoin. Il y a deux façons de faire ceci :
- Allez-y et essayez l'appel API et si vous obtenez une
UNAUTHORIZED
erreur en réponse, allez chercher un nouveau jeton et réitère l'appel de l'API. Dans ce cas, la séquence de traitement ressemblera à ceci :Obtenir un jeton avec Check for Call Fail - Une autre approche consisterait à ajouter la
expires_in
valeur à l'heure actuelle en secondes Epoch chaque fois que vous récupérez un jeton, puis sur les appels d'API ultérieurs, vérifiez l'heure d'expiration par rapport à l'heure actuelle pour voir si vous avez besoin d'extraire un nouveau jeton. Dans ce cas, votre séquence de traitement ressemblera à ceci :Obtenir un jeton avec Vérifier l'expiration
Facteur et insomnie
Plusieurs outils de test utiles pour les API REST peuvent être configurés pour fonctionner avec le système OAuth Brightcove pour obtenir des jetons d'accès. Nous avons des guides qui incluent des étapes pour ce faire pour deux des outils multiplateformes les plus populaires :
Échantillons de code
Voici quelques exemples de code pour vous aider à démarrer.
Exemple de script Shell
Le premier exemple est un script shell qui implémente la première logique d'implémentation ci-dessus : il prend les entrées de l'utilisateur, obtient toujours un nouveau jeton, puis effectue l'appel d'API. Le script fonctionnera sur n'importe quelle API Brightcove, et vous pouvez le trouver utile pour tester les appels d'API lors de la création de votre application.
Code de script Shell

Exemple Ruby
L'exemple suivant est un script Ruby qui utilise également la première logique d'implémentation : toujours obtenir un jeton, puis faire l'appel d'API. Cet exemple effectue un appel à l'API Analytics, mais peut être adapté pour fonctionner avec n'importe laquelle des API.
Code Ruby
#!/usr/bin/env ruby
# view id --> content,
#!/usr/bin/env ruby
require 'rest-client'
require 'json'
client_id = '5eb0f20e-29a8-4f19-8cb5-80336e2789ab'
client_secret = 'Zqpb_2YrvnGUEjqQUndx6GsjQ3JyAgXoA2gNbhoj-yUV4scij0jwCN0OBz9FILEwHupjeqwdbOUSFMi7zkhpVg'
response = RestClient.post 'https://oauth.brightcove.com/v4/access_token', :client_id=>client_id,:client_secret=>client_secret,:grant_type=>'client_credentials'
token = JSON.parse(response)["access_token"]
puts "The extracted token is:" + token + "\n\n\n"
data = RestClient.get 'https://data.brightcove.com/analytics-api/videocloud/account/1234567890001/report?dimensions=video&from=2014-01-01&to=2014-03-30', { 'Authorization' => "Bearer #{token}", 'Accept' => 'application/json' }
puts "This is the result from the query: \n" + data
Exemple Python
Cet exemple est un script Python qui implémente la troisième logique d'implémentation ci-dessus. Il tente d'effectuer un Analytics API appel, mais si l'appel échoue sur une erreur NON AUTORISÉE, il récupère un nouveau jeton d'accès et tente de nouveau l'appel.
Ce script lit également les informations d'identification client à partir d'un fichier externe - le fichier de données d'identification est affiché sous le code Python.

# To use this script, edit the configuration file brightcove_oauth.txt
