Kode sampel
Anda dapat mengirim permintaan anotasi dengan file yang disimpan secara lokal, atau menggunakan file yang disimpan di Cloud Storage.
Menggunakan file yang disimpan secara lokal
Gunakan contoh kode berikut untuk mendapatkan fitur anotasi untuk file yang disimpan secara lokal.
REST
Untuk melakukan deteksi fitur PDF/TIFF/GIF online untuk file batch kecil, buat permintaan POST dan berikan isi permintaan yang sesuai:
Sebelum menggunakan salah satu data permintaan, lakukan penggantian berikut:
- BASE64_ENCODED_FILE: Representasi base64
(ASCII string) data file biner Anda. String ini akan terlihat seperti
string berikut:
JVBERi0xLjUNCiW1tbW1...ydHhyZWYNCjk5NzM2OQ0KJSVFT0Y=
- PROJECT_ID: ID project Google Cloud Anda.
Pertimbangkan khusus kolom:
inputConfig.mimeType
- Salah satu dari berikut ini: "aplikasi/pdf", "gambar/tiff", atau "gambar/gif".pages
- menentukan halaman tertentu dari file untuk melakukan deteksi fitur.
Metode HTTP dan URL:
POST https://vision.googleapis.com/v1/files:annotate
Isi JSON permintaan:

Permintaan annotate
yang berhasil akan segera menampilkan respons JSON.
Untuk fitur ini (DOCUMENT_TEXT_DETECTION
), respons JSON mirip dengan
permintaan deteksi teks dokumengambar. Responsnya
berisi kotak pembatas untuk blok yang dipecah menurut paragraf, kata, dan simbol
individual. Teks lengkap juga terdeteksi. Responsnya juga berisi kolom context
yang menunjukkan lokasi PDF atau TIFF yang ditentukan dan nomor halaman hasil pada
file tersebut.
