is there a way to iterate over all items in some album, in google photos? I'm using the google photos provided API, and from what im aware of, I can only get access to 100 media items at a time, using the following:
def create_service(client_secret_file, api_name, api_version, scopes):
print(client_secret_file, api_name, api_version, scopes, sep=', ')
SCOPES = [scope for scope in scopes[0]]
cred = None
pickle_file = f'token_{api_name}_{api_version}.pickle'
if os.path.exists(pickle_file):
with open(pickle_file, 'rb') as token:
cred = pickle.load(token)
if not cred or not cred.valid:
if cred and cred.expired and cred.refresh_token:
cred.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
client_secret_file, SCOPES)
cred = flow.run_local_server()
with open(pickle_file, 'wb') as token:
pickle.dump(cred, token)
service = build(api_name, api_version, credentials=cred)
print(api_name, 'service created successfully')
return service
service = create_service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)
media = service.mediaItems().list(pageSize=MEDIA_TO_SHOW).execute()
where all the upper case are some non relevant string and int constants, that indicate the api's name, the scopes accessible, etc...(for readability). specifically, MEDIA_TO_SHOW = 100
thanks for the help
At the method of "mediaItems.list" in Google Photos API, the maximum value of pageSize is 100. When you want to retrieve more items, it is required to use pageToken. At the official document of pageToken, it says as follows.
pageToken: A continuation token to get the next page of the results. Adding this to the request returns the rows after the pageToken. The pageToken should be the value returned in the nextPageToken parameter in the response to the listMediaItems request.
When this is reflected to your script, it becomes as follows.
service = create_service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)
# I modified below script.
MEDIA_TO_SHOW = 100
mediaItemList = []
pageToken = ""
while True:
res = service.mediaItems().list(pageSize=MEDIA_TO_SHOW, pageToken=pageToken if pageToken != "" else "").execute()
mediaItems = res.get('mediaItems', [])
mediaItemList.extend(mediaItems)
pageToken = res.get('nextPageToken')
if not pageToken:
break
print(len(mediaItemList)) # You can see the number of items here.
service can be used for the method of service.mediaItems().list().If you want to retrieve the item list from the specific album, please use the following script.
service = create_service(CLIENT_SECRET_FILE, API_NAME, API_VERSION, SCOPES)
# I modified below script.
album_id = "###" # Please set the album ID.
MEDIA_TO_SHOW = 100
mediaItemList = []
pageToken = ""
while True:
body = {
"albumId": album_id,
"pageToken": pageToken if pageToken != "" else "",
"pageSize": MEDIA_TO_SHOW
}
res = service.mediaItems().search(body=body).execute()
mediaItems = res.get('mediaItems', [])
mediaItemList.extend(mediaItems)
pageToken = res.get('nextPageToken')
if not pageToken:
break
print(len(mediaItemList)) # You can see the number of items here.
