Method jobs.list

Elenca le prestazioni di segnalazione che sono state programmate per un canale o un proprietario dei contenuti. Ogni risorsa nella risposta contiene una proprietà id, che specifica l'ID utilizzato da YouTube per identificare in modo univoco il job. Questo ID è necessario per recuperare l'elenco dei report generati per il job o per eliminare il job.

Richiesta

Richiesta HTTP

GET https://youtubereporting.googleapis.com/v1/jobs

Autorizzazione

Tutte le richieste all'API di reporting di YouTube devono essere autorizzate. La guida all'autorizzazione spiega come utilizzare il protocollo OAuth 2.0 per recuperare i token di autorizzazione.

Le richieste all'API di reporting di YouTube utilizzano i seguenti ambiti di autorizzazione:

Ambiti
https://www.googleapis.com/auth/yt-analytics.readonly Visualizzare i report Analytics su YouTube per i tuoi contenuti di YouTube. Questo ambito consente di accedere alle metriche relative all'attività utente, come il numero di visualizzazioni e di valutazioni.
https://www.googleapis.com/auth/yt-analytics-monetary.readonly Visualizzare i report di YouTube Analytics relativi al valore monetario per i tuoi contenuti di YouTube. Questo ambito consente di accedere alle metriche relative all'attività utente e alle metriche sul rendimento degli annunci e sulle entrate stimate.

Parametri

Parametri di ricerca

Parametri
onBehalfOfContentOwner string
L'ID del proprietario dei contenuti per il quale viene effettuata la richiesta API. Se la richiesta non specifica un valore per questo parametro, il server API presume che la richiesta venga effettuata per il canale dell'utente.
pageSize number
Le dimensioni di pagina richieste. Se non viene specificato alcun valore, il server API sceglie un valore predefinito appropriato.

Tieni presente che il server potrebbe restituire un numero inferiore di tipi di report rispetto a quelli richiesti.
pageToken string
Un token che identifica una pagina di risultati che il server deve restituire. In genere, corrisponde al valore della proprietà nextPageToken restituita in risposta alla precedente chiamata al metodo jobs.list.
includeSystemManaged boolean
Imposta il valore del parametro su true per indicare che la risposta dell'API deve includere job per i report gestiti dal sistema.

YouTube genera automaticamente report gestiti dal sistema per i proprietari dei contenuti YouTube che hanno accesso agli stessi report nel menu Report. Pertanto, i proprietari dei contenuti non devono chiamare il metodo jobs.create per indicare a YouTube di iniziare a generare i report e questo metodo restituisce un errore se la proprietà reportTypeId identifica un report gestito dal sistema.

Il valore predefinito del parametro è false.

Corpo della richiesta

Il corpo della richiesta deve essere vuoto.

Risposta

In caso di esito positivo, questo metodo restituisce un corpo della risposta con la seguente struttura:

{
  "jobs": [
    Job resource
  ],
  "nextPageToken": string
}
Proprietà
jobs[] list
Un elenco di segnalazioni di lavori che sono stati programmati per il canale o il proprietario dei contenuti associato alla richiesta. Ogni elemento nell'elenco è una risorsa job.
nextPageToken string
Se la risposta dell'API contiene un valore per questa proprietà, saranno disponibili offerte di lavoro aggiuntive per il canale o il proprietario dei contenuti associato. Per recuperare questi job, invia un'ulteriore richiesta jobs.list, impostando il valore del parametro pageToken su questo valore.

Esempi

Nota: gli esempi di codice riportati di seguito potrebbero non rappresentare tutti i linguaggi di programmazione supportati. Consulta la documentazione relativa alle librerie client per un elenco delle lingue supportate.

Java

L'esempio riportato di seguito utilizza la libreria client Java.

Questo esempio mostra come recuperare i report creati da un job specifico. Chiama il metodo jobs.list per recuperare i job di reporting. Quindi chiama il metodo reports.list con il parametro jobId impostato su un ID job specifico per recuperare i report creati dal job. Infine, nell'esempio viene stampato l'URL di download di ciascun report.

# This script retrieves YouTube Reporting API reports. Use cases:
# 1. If you specify a report URL, the script downloads that report.
# 2. Otherwise, if you specify a job ID, the script retrieves a list of
#    available reports for that job and prompts you to select a report.
#    Then it retrieves that report as in case 1.
# 3. Otherwise, the list retrieves a list of jobs for the user or,
#    if specified, the content owner that the user is acting on behalf of.
#    Then it prompts the user to select a job, and then executes case 2 and
#    then case 1.
