getfilelistpy
Overview
This is a python library to retrieve the file list with the folder tree from the specific folder of Google Drive.
Description
When I create applications for using Google Drive, I often retrieve a file list from a folder in the application. So far, I had created the script for retrieving a file list from a folder for each application. Recently, I thought that if there is the script for retrieving the file list with the folder tree from the folder of Google Drive as a library, it will be useful for me and other users. So I created this.
Features
- This library retrieves all files from a folder in Google Drive.
- All files include the folder structure in Google Drive.
- Only folder tree can be also retrieved.
Install
$ pip install getfilelistpy
You can also check this library at https://pypi.org/project/getfilelistpy/.
Method
Method | Explanation |
---|---|
GetFolderTree(object) | Retrieve only folder structure from a folder |
GetFileList(object) | Retrieve file list with folder structure from a folder |
Usage
There are 3 patterns for using this library.
1. Use API key
This is a sample script using API key. When you want to retrieve the API key, please do the following flow.
- Login to Google.
- Access to https://console.cloud.google.com/?hl=en.
- Click select project at the right side of "Google Cloud Platform" of upper left of window.
- Click "NEW PROJECT"
- Input "Project Name".
- Click "CREATE".
- Open the created project.
- Click "Enable APIs and get credentials like keys".
- Click "Library" at left side.
- Input "Drive API" in "Search for APIs & Services".
- Click "Google Drive API".
- Click "ENABLE".
- Back to https://console.cloud.google.com/?hl=en.
- Click "Enable APIs and get credentials like keys".
- Click "Credentials" at left side.
- Click "Create credentials" and select API key.
- Copy the API key. You can use this API key.
Sample script
from getfilelistpy import getfilelist
resource = {
"api_key": "#####",
"id": "### Folder ID ###",
"fields": "files(name,id)",
}
res = getfilelist.GetFileList(resource) # or r = getfilelist.GetFolderTree(resource)
print(res)
Note
- When you want to retrieve the file list from the folder using API key, the folder is required to be shared.
- You can modify the property of
fields
. When this is not used, the default fields are used.
2. Use OAuth2
Document of OAuth2 is here.
Sample script 1
In this sample script for oauth2client
.
from httplib2 import Http
from oauth2client import file, client, tools
from getfilelistpy import getfilelist
SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'
store = file.Storage('token.json')
creds = store.get()
if not creds or creds.invalid:
flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
creds = tools.run_flow(flow, store)
resource = {
"oauth2": creds.authorize(Http()),
"id": "### Folder ID ###",
"fields": "files(name,id)",
}
res = getfilelist.GetFileList(resource) # or r = getfilelist.GetFolderTree(resource)
print(res)
Sample script 2
In this sample script for google_auth_oauthlib
, the process of OAuth2 uses the quickstart of Google. Please check this.
import pickle
import os.path
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request
from getfilelistpy import getfilelist
SCOPES = 'https://www.googleapis.com/auth/drive.metadata.readonly'
creds = None
creFile = 'token.pickle'
if os.path.exists(creFile):
with open(creFile, 'rb') as token:
creds = pickle.load(token)
if not creds or not creds.valid:
if creds and creds.expired and creds.refresh_token:
creds.refresh(Request())
else:
flow = InstalledAppFlow.from_client_secrets_file(
'client_secret.json', SCOPES)
creds = flow.run_local_server()
with open(creFile, 'wb') as token:
pickle.dump(creds, token)
resource = {
"oauth2": creds,
"id": "### Folder ID ###",
"fields": "files(name,id)",
}
res = getfilelist.GetFileList(resource) # or r = getfilelist.GetFolderTree(resource)
print(res)
Note
- Here, as a sample, the script of the authorization uses the script of quickstart.
- You can modify the property of
fields
. When this is not used, the default fields are used.
3. Use Service account
Document of Service account is here.
Sample script
from google.oauth2 import service_account
from getfilelistpy import getfilelist
SCOPES = ['https://www.googleapis.com/auth/drive']
SERVICE_ACCOUNT_FILE = 'service-account-credentials.json'
credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES)
resource = {
"service_account": credentials,
"id": "### Folder ID ###",
"fields": "files(name,id)",
}
res = getfilelist.GetFileList(resource) # or r = getfilelist.GetFolderTree(resource)
print(res)
Note
- You can modify the property of
fields
. When this is not used, the default fields are used.
Values
As a sample, when the values are retrieved from above structure, the results of GetFolderTree()
becomes as follows.
