Memilih file dan folder Google Drive dengan Pemilih Google

Untuk mengizinkan pengguna memilih file atau folder dari Google Drive, Anda dapat mengonfigurasi widget SelectionInput agar menggunakan Pemilih Google. Panduan ini menjelaskan cara menyiapkan Pemilih Google di kartu konfigurasi add-on Anda.

Mengonfigurasi Pemilih Google

Untuk mengaktifkan widget input pilihan guna memilih file atau folder dari Google Drive, Anda harus mengonfigurasi PlatformDataSource-nya dengan CommonDataSource dan DriveDataSourceSpec.

  1. Tetapkan CommonDataSource ke DRIVE. Tindakan ini menetapkan Google Drive sebagai sumber untuk input pilihan.
  2. (Opsional) Untuk menentukan jenis file yang dapat dipilih pengguna, tambahkan DriveDataSourceSpec. Anda dapat menentukan satu atau beberapa jenis item berikut:
    • DOCUMENTS
    • SPREADSHEETS
    • PRESENTATIONS
    • PDFS
    • FORMS
    • FOLDERS

Contoh: Memilih spreadsheet dan PDF

Contoh berikut membuat kartu konfigurasi yang memungkinkan pengguna memilih beberapa spreadsheet atau file PDF dari Google Drive. Saat langkah berjalan, langkah ini akan menampilkan ID file item yang dipilih sebagai variabel output.
