Menggunakan plugin TIP untuk mengakses Layanan AWS

Untuk menggunakan plugin TIP dalam AWS SDK untuk Java proyek Anda, Anda perlu mendeklarasikannya sebagai dependensi dalam file proyek Anda. pom.xml

<dependency>
<groupId>software.amazon.awsidentity.trustedIdentityPropagation</groupId>
<artifactId>aws-sdk-java-trustedIdentityPropagation-java-plugin</artifactId>
   <version>2.0.0</version>
</dependency>

Dalam kode sumber Anda, sertakan pernyataan paket yang diperlukan untuksoftware.amazon.awssdk.trustedidentitypropagation.

Contoh berikut menunjukkan dua cara untuk membuat instance plugin propagasi identitas tepercaya dan menambahkannya ke klien layanan. Kedua contoh menggunakan Amazon S3 sebagai layanan dan digunakan S3AccessGrantsPlugin untuk mengelola izin khusus pengguna, tetapi dapat diterapkan ke semua Layanan AWS yang mendukung propagasi identitas tepercaya (TIP).

Opsi 1: Bangun dan lewati klien OIDC dan STS

SsoOidcClient oidcClient = SsoOidcClient.builder()
    .region(Region.US_EAST_1)
    .credentialsProvider(credentialsProvider).build();

StsClient stsClient = StsClient.builder()
    .region(Region.US_EAST_1)
    .credentialsProvider(credentialsProvider).build();

TrustedIdentityPropagationPlugin trustedIdentityPropagationPlugin = TrustedIdentityPropagationPlugin.builder()
        .webTokenProvider(() -> webToken)
        .applicationArn(idcApplicationArn)
        .accessRoleArn(accessRoleArn)
        .ssoOidcClient(oidcClient)
        .stsClient(stsClient)
        .build();

S3AccessGrantsPlugin accessGrantsPlugin = S3AccessGrantsPlugin.builder()
        .build();

S3Client s3Client =
        S3Client.builder().region(Region.US_EAST_1)
                .crossRegionAccessEnabled(true)
                .addPlugin(trustedIdentityPropagationPlugin)
                .addPlugin(accessGrantsPlugin)
                .build();

final var resp = s3Client.getObject(GetObjectRequest.builder()
        .key("path/to/object/fileName")
        .bucket("bucketName")
        .build());

Opsi 2: Lulus applicationRoleArn dan tunda pembuatan klien ke plugin

TrustedIdentityPropagationPlugin trustedIdentityPropagationPlugin = TrustedIdentityPropagationPlugin.builder()
        .webTokenProvider(() -> webToken)
        .applicationArn(idcApplicationArn)
        .accessRoleArn(accessRoleArn)
        .applicationRoleArn(applicationRoleArn)
        .build();

S3AccessGrantsPlugin accessGrantsPlugin = S3AccessGrantsPlugin.builder()
        .build();

S3Client s3Client =
        S3Client.builder().region(Region.US_EAST_1)
                .crossRegionAccessEnabled(true)
                .addPlugin(trustedIdentityPropagationPlugin)
                .addPlugin(accessGrantsPlugin)
                .build();

final var resp = s3Client.getObject(GetObjectRequest.builder()
        .key("path/to/object/fileName")
        .bucket("bucketName")
        .build());

Jalankan perintah berikut untuk menginstal paket plugin otentikasi TIP dalam AWS SDK untuk JavaScript proyek Anda:

$  npm i @aws-sdk-extension/trusted-identity-propagation

Final package.json harus mencakup ketergantungan yang mirip dengan yang berikut:

  "dependencies": {
"@aws-sdk-extension/trusted-identity-propagation": "^2.0.0"
  },

Dalam kode sumber Anda, impor TrustedIdentityPropagationExtension dependensi yang diperlukan.

Contoh berikut menunjukkan dua cara untuk membuat instance plugin propagasi identitas tepercaya dan menambahkannya ke klien layanan. Kedua contoh menggunakan Amazon S3 sebagai layanan dan memanfaatkan Amazon S3 Access Grants untuk mengelola izin khusus pengguna, tetapi dapat diterapkan ke semua yang mendukung propagasi identitas Layanan AWS tepercaya (TIP).
