java - AmazonS3异常 : Access Denied

Question

我尝试连接到 s3 存储桶来上传/下载图像。

我创建 s3 客户端的代码如下:

AmazonS3 s3 = AmazonS3ClientBuilder
            .standard()
            .withRegion("EU-WEST-2")
            .build();

我收到如下异常:

com.amazonaws.services.s3.model.AmazonS3Exception: Access Denied (Service: Amazon S3; Status Code: 403; Error Code: AccessDenied; Request ID: 8574612863BD8DC2; S3 Extended Request ID: ueyZy/RLMerNtHeYaOTlRVAqD7w1CksWrjfNLuMgxPWXQbNGDF1Y04RUs4Gh9HeHMwLXxjBc+5o=), S3 Extended Request ID: ueyZy/RLMerNtHeYaOTlRVAqD7w1CksWrjfNLuMgxPWXQbNGDF1Y04RUs4Gh9HeHMwLXxjBc+5o=

Answer 1

试试这个，您需要根据您的访问 key 和 secret 更改 env.getProperty("amazon.accessKey")。

public AmazonS3 getAmazonS3Client() {

        ClientConfiguration clientConfig = new ClientConfiguration();
        clientConfig.setProtocol(Protocol.HTTP);
        AmazonS3 s3client = new AmazonS3Client(getAmazonCredentials(), clientConfig);
        s3client.setS3ClientOptions(S3ClientOptions
                .builder()
                .setPathStyleAccess(true)
                .disableChunkedEncoding().build());

        return s3client;
    }

    public AWSCredentials getAmazonCredentials() {
        AWSCredentials credentials = new BasicAWSCredentials(
                env.getProperty("amazon.accessKey"),
                env.getProperty("amazon.secretKey")
        );
        return credentials;
    }

要检查存储桶是否存在并上传文件，请检查此项。

AmazonS3 s3client = amazonS3ClientService.getAmazonS3Client();
    if (!s3client.doesBucketExistV2(env.getProperty("amazon.bucket"))) {
        System.out.println("Bucket is not Exist.");
        return RepeatStatus.FINISHED;
    }

    // Upload Dir
    TransferManager transferManager = new TransferManager(amazonS3ClientService.getAmazonCredentials());
    MultipleFileUpload upload =
            transferManager.uploadDirectory(env.getProperty("amazon.bucket"), file.getName(), file,true);

如果您想上传单个文件，请尝试此操作，

 s3client .putObject(bucket_name, key_name, new File(file_path));
