Contoh 1: Untuk mendapatkan metadata set gambar tanpa versi

Contoh get-image-set-metadata kode berikut mendapatkan metadata untuk kumpulan gambar tanpa menentukan versi.

Catatan: outfile adalah parameter yang diperlukan

aws medical-imaging get-image-set-metadata \
    --datastore-id 12345678901234567890123456789012 \
    --image-set-id ea92b0d8838c72a3f25d00d13616f87e \
    studymetadata.json.gz

Metadata yang dikembalikan dikompresi dengan gzip dan disimpan dalam file studymetadata.json.gz. Untuk melihat isi JSON objek yang dikembalikan, Anda harus terlebih dahulu mendekompresnya.

Output:

{
    "contentType": "application/json",
    "contentEncoding": "gzip"
}

Contoh 2: Untuk mendapatkan metadata set gambar dengan versi

Contoh get-image-set-metadata kode berikut mendapatkan metadata untuk set gambar dengan versi tertentu.

Catatan: outfile adalah parameter yang diperlukan

aws medical-imaging get-image-set-metadata \
    --datastore-id 12345678901234567890123456789012 \
    --image-set-id ea92b0d8838c72a3f25d00d13616f87e \
    --version-id 1 \
    studymetadata.json.gz

Metadata yang dikembalikan dikompresi dengan gzip dan disimpan dalam file studymetadata.json.gz. Untuk melihat isi JSON objek yang dikembalikan, Anda harus terlebih dahulu mendekompresnya.

Output:

{
    "contentType": "application/json",
    "contentEncoding": "gzip"
}
