要使用AWSS3TransferUtility进行上传时的Cognito身份验证配置,您可以按照以下步骤进行操作:
AWSCognitoIdentityUserPool
和AWSCognitoIdentityUserPoolConfiguration
的引用。AWSCognitoIdentityUserPoolConfiguration poolConfig = new AWSCognitoIdentityUserPoolConfiguration.Builder()
.clientId("YOUR_COGNITO_CLIENT_ID")
.clientSecret("YOUR_COGNITO_CLIENT_SECRET")
.poolId("YOUR_COGNITO_POOL_ID")
.build();
AWSCognitoIdentityUserPool userPool = new AWSCognitoIdentityUserPool(context, poolConfig);
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
context,
"YOUR_COGNITO_POOL_ID",
"YOUR_COGNITO_REGION"
);
AWSS3TransferUtility transferUtility = AWSS3TransferUtility.builder()
.context(context)
.defaultBucket("YOUR_S3_BUCKET")
.s3Client(new AmazonS3Client(credentialsProvider))
.cognitoAWSCredentialsProvider(credentialsProvider)
.build();
TransferObserver uploadObserver = transferUtility.upload(
"YOUR_S3_BUCKET",
"YOUR_OBJECT_KEY",
new File("YOUR_FILE_PATH"),
CannedAccessControlList.PublicRead // 设置对象的访问权限,根据需要进行更改
);
uploadObserver.setTransferListener(new TransferListener() {
@Override
public void onStateChanged(int id, TransferState state) {
if (state == TransferState.COMPLETED) {
// 上传完成
}
}
@Override
public void onProgressChanged(int id, long bytesCurrent, long bytesTotal) {
// 更新上传进度
}
@Override
public void onError(int id, Exception ex) {
// 上传出错
}
});
请确保替换代码中的"YOUR_COGNITO_CLIENT_ID","YOUR_COGNITO_CLIENT_SECRET","YOUR_COGNITO_POOL_ID","YOUR_COGNITO_REGION","YOUR_S3_BUCKET","YOUR_OBJECT_KEY"和"YOUR_FILE_PATH"与您的实际值相匹配。
