# Mendapatkan informasi unduhan file

> Panggil API ini untuk mendapatkan informasi unduhan file di ruang penyimpanan, termasuk URL unduhan, guna menerapkan proses unduh file di DingTalk.

Panggil API ini untuk mendapatkan informasi unduhan file di ruang penyimpanan.

## Deskripsi panggilan API

Langkah 1: Panggil API ini untuk mendapatkan informasi unduhan file, termasuk URL unduhan dan header.

Langkah 2: Jalankan proses unduh. Lihat contoh berikut:

```java theme={"theme":{"light":"github-light","dark":"github-dark"}}
public static void main(String[] args) {
        String url = ""; // internalResourceUrls yang dikembalikan oleh API dapatkan informasi unduhan.
        String path = "/Users/xxxxx/Downloads/test.txt"; // Jalur target untuk unduhan file.
        // Header yang dikembalikan oleh API dapatkan informasi unduhan.
        Map<String, String> headers = "" // Header yang diperoleh dari API dapatkan informasi unduhan.
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url(url)
                .headers(Headers.of(headers))
                .build();
        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                Sink sink = null;
                BufferedSink bufferedSink = null;
                try {
                    File dest = new File(path);
                    sink = Okio.sink(dest);
                    bufferedSink = Okio.buffer(sink);
                    bufferedSink.writeAll(response.body().source());
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    if (bufferedSink != null) {
                        bufferedSink.close();
                    }
                    if (sink != null) {
                        sink.close();
                    }
                }
            }
        });
    }
```

<Note>
  Jika file terlalu besar dan Anda perlu mengambilnya secara bertahap, tambahkan bidang headers pada contoh di atas: `headers.put("Range","bytes=0-499");`. Untuk detailnya, lihat [Mengunduh sebagian konten dengan menentukan Range](/id/open/development/use-range-download-a-part-of-content).
