Google Drive memungkinkan Anda untuk menyimpan file Anda di cloud, yang dapat Anda akses kapan saja dan di mana saja di dunia. Dalam tutorial ini, Anda akan belajar cara membuat daftar file Google drive Anda, mencarinya, mengunduh file yang disimpan, dan bahkan mengunggah file lokal ke drive Anda secara terprogram menggunakan Python
Berikut adalah daftar isi
Untuk memulai, mari instal pustaka yang diperlukan untuk tutorial ini
pip3 install google-api-python-client google-auth-httplib2 google-auth-oauthlib tabulate requests tqdmAktifkan API Drive
Mengaktifkan Google Drive API sangat mirip dengan Google API lainnya seperti Gmail API, YouTube API, atau Google Search Engine API. Pertama, Anda harus memiliki akun Google dengan Google Drive diaktifkan. Buka halaman ini dan klik tombol "Enable the Drive API" seperti yang ditunjukkan di bawah ini
Jendela baru akan muncul; . Saya akan tetap menggunakan "Aplikasi desktop" dan kemudian menekan tombol "Buat". Setelah itu, Anda akan melihat jendela lain muncul mengatakan Anda sudah siap
Unduh kredensial Anda dengan mengklik tombol "Unduh Konfigurasi Klien" dan kemudian "Selesai"
Terakhir, Anda perlu memasukkan import pickle import os from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow from google.auth.transport.requests import Request from tabulate import tabulate # If modifying these scopes, delete the file token.pickle. SCOPES = ['//www.googleapis.com/auth/drive.metadata.readonly'] def get_gdrive_service(): creds = None # The file token.pickle stores the user's access and refresh tokens, and is # created automatically when the authorization flow completes for the first # time. if os.path.exists('token.pickle'): with open('token.pickle', 'rb') as token: creds = pickle.load(token) # If there are no (valid) credentials available, let the user log in. 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( 'credentials.json', SCOPES) creds = flow.run_local_server(port=0) # Save the credentials for the next run with open('token.pickle', 'wb') as token: pickle.dump(creds, token) # return Google Drive API service return build('drive', 'v3', credentials=creds)_8 yang diunduh ke direktori kerja Anda (mis. e. , tempat Anda menjalankan skrip Python yang akan datang)
Daftar File dan Direktori
Sebelum kita melakukan apapun, kita perlu mengautentikasi kode kita ke akun Google kita. Fungsi di bawah melakukan itu

Fungsi di atas diambil dari halaman quickstart Google Drive. Ini pada dasarnya mencari file import pickle import os from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow from google.auth.transport.requests import Request from tabulate import tabulate # If modifying these scopes, delete the file token.pickle. SCOPES = ['//www.googleapis.com/auth/drive.metadata.readonly'] def get_gdrive_service(): creds = None # The file token.pickle stores the user's access and refresh tokens, and is # created automatically when the authorization flow completes for the first # time. if os.path.exists('token.pickle'): with open('token.pickle', 'rb') as token: creds = pickle.load(token) # If there are no (valid) credentials available, let the user log in. 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( 'credentials.json', SCOPES) creds = flow.run_local_server(port=0) # Save the credentials for the next run with open('token.pickle', 'wb') as token: pickle.dump(creds, token) # return Google Drive API service return build('drive', 'v3', credentials=creds)_9 untuk mengautentikasi dengan akun Google Anda. Jika tidak menemukannya, itu akan menggunakan import pickle import os from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow from google.auth.transport.requests import Request from tabulate import tabulate # If modifying these scopes, delete the file token.pickle. SCOPES = ['//www.googleapis.com/auth/drive.metadata.readonly'] def get_gdrive_service(): creds = None # The file token.pickle stores the user's access and refresh tokens, and is # created automatically when the authorization flow completes for the first # time. if os.path.exists('token.pickle'): with open('token.pickle', 'rb') as token: creds = pickle.load(token) # If there are no (valid) credentials available, let the user log in. 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( 'credentials.json', SCOPES) creds = flow.run_local_server(port=0) # Save the credentials for the next run with open('token.pickle', 'wb') as token: pickle.dump(creds, token) # return Google Drive API service return build('drive', 'v3', credentials=creds)8 untuk meminta Anda untuk otentikasi di browser Anda. Setelah itu, itu akan memulai layanan Google Drive API dan mengembalikannya
Pergi ke fungsi utama, mari kita tentukan fungsi yang mencantumkan file di drive kita
def main(): """Shows basic usage of the Drive v3 API. Prints the names and ids of the first 5 files the user has access to.

Perhatikan kita menggunakan fungsi def main(): """Shows basic usage of the Drive v3 API. Prints the names and ids of the first 5 files the user has access to.

Ingat setelah Anda menjalankan skrip, Anda akan diminta di browser default Anda untuk memilih akun Google Anda dan mengizinkan aplikasi Anda untuk cakupan yang Anda tentukan sebelumnya, jangan khawatir, ini hanya akan terjadi saat pertama kali Anda menjalankannya, lalu
Catatan. Terkadang, Anda akan menemukan peringatan "Aplikasi ini tidak divalidasi" (karena Google tidak memverifikasi aplikasi Anda) setelah memilih akun Google Anda. Tidak apa-apa untuk pergi ke bagian "Lanjutan" dan mengizinkan aplikasi ke akun Anda

Unduh File
Untuk mendownload file, kita perlu terlebih dahulu mendapatkan file yang ingin kita download. Kami dapat mencarinya menggunakan kode sebelumnya atau secara manual mendapatkan ID drive-nya. Di bagian ini, kita akan mencari file berdasarkan nama dan mengunduhnya ke disk lokal kita

Baiklah, begitulah. Ini pada dasarnya adalah fungsi inti dari Google Drive. Sekarang Anda tahu cara melakukannya dengan Python tanpa klik mouse manual
Ingat, setiap kali Anda mengubah daftar def list_files(items): """given items returned by Google Drive API, prints them in a tabular way""" if not items: # empty drive print('No files found.') else: rows = [] for item in items: # get the File ID id = item["id"] # get the name of file name = item["name"] try: # parent directory ID parents = item["parents"] except: # has no parrents parents = "N/A" try: # get the size in nice bytes format (KB, MB, etc.) size = get_size_format(int(item["size"])) except: # not a file, may be a folder size = "N/A" # get the Google Drive type of file mime_type = item["mimeType"] # get last modified date time modified_time = item["modifiedTime"] # append everything to the list rows.append((id, name, parents, size, mime_type, modified_time)) print("Files:") # convert to a human readable table table = tabulate(rows, headers=["ID", "Name", "Parents", "Size", "Type", "Modified Time"]) # print the table print(table)3, Anda perlu menghapus file import pickle import os from googleapiclient.discovery import build from google_auth_oauthlib.flow import InstalledAppFlow from google.auth.transport.requests import Request from tabulate import tabulate # If modifying these scopes, delete the file token.pickle.
