Android Amazon S3 TransferUtility

Question

我正在尝试使用以下代码将图像上传到亚马逊 (AWS SDK 2.3.0) s3

        CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
            getApplicationContext(),
            "XXXXXXX",
            // Identity Pool ID
            Regions.EU_WEST_1 // Region
    );
    AmazonS3Client s3Client = new AmazonS3Client(credentialsProvider);

    TransferUtility transferUtility = new TransferUtility(s3Client, this.
            getApplicationContext());

    TransferObserver observer = transferUtility.upload("testbucketzzzz", "test.jpg",
            file);

每次我尝试上传图片时都会收到以下错误

UploadTask: Failed to upload: 37 due to The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256. (Service: Amazon S3; Status Code: 400; Error Code: InvalidRequest; Request ID: 9787E53737D02BA7)

我认为这只会是旧版 AWS SDK 的问题。经过无数小时的修复尝试后，我发现了以下内容 "trick" 但这只会导致我出现另一个错误，根本不需要。

        System.setProperty(SDKGlobalConfiguration.ENABLE_S3_SIGV4_SYSTEM_PROPERTY, "true");

您可以使用以下代码片段将图片上传到 Amazon S3（确保您在 MainThread 中没有这样做）：

    BasicAWSCredentials basicAWSCredentials = new BasicAWSCredentials(
          ACCESS_KEY,
          SECRET_KEY
      );
    AmazonS3Client s3Client = new AmazonS3Client(basicAWSCredentials);
      s3Client.setEndpoint(ENDPOINT);
      s3Client.setRegion(Region.getRegion(Regions.EU_WEST_1));;
    PutObjectRequest por = new PutObjectRequest(
                "YOUR_BUCKET_NAME", "YOUR_KEY", file);
    }
    s3Client.putObject(por);
