com.amazonaws.services.s3.model.PutObjectRequest的PutObjectRequest.putObject（）方法抛出com.amazonaws.services.s3.model.AmazonS3Exception

Question

Hey I am trying to upload an image to s3 bucket my code is:

public static void addObjectToBucketFromStream(AmazonS3 conn,
        String bucketName, String keyName, InputStream inputStream,
        Map<String, String> metadataMap,String contentType) throws IOException {
    try {
        ObjectMetadata metadata = new ObjectMetadata();
        if (metadataMap != null) {
            for (Iterator iterator = metadataMap.keySet().iterator(); iterator
                    .hasNext();) {
                String key = (String) iterator.next();
                String value = metadataMap.get(key);
                metadata.addUserMetadata(key, value);
            }
        }
        metadata.setContentLength(inputStream.available());
        if (contentType!=null && !"".equals(contentType)){
            metadata.setContentType(contentType);
        }
        PutObjectRequest por = new PutObjectRequest(bucketName, keyName,
                inputStream, metadata);
        por.setCannedAcl(CannedAccessControlList.PublicRead);
        conn.putObject(por);
        int a;
    } finally {
        if (inputStream != null) {
            try {
                inputStream.close();
            } catch (IOException e) {
                // ignore
            }
        }
    }
}

In this code putObject() throws com.amazonaws.services.s3.model.PutObjectRequest throws com.amazonaws.services.s3.model.AmazonS3Exception

In log it is showing

com.amazonaws.services.s3.model.AmazonS3Exception: Status Code: 403, AWS Service: Amazon S3, AWS Request ID: 8C576CDFEC92534C, AWS Error Code: AccessDenied, AWS Error Message: Access Denied, S3 Extended Request ID: q7Rs1xrUbnJgptnJKS5T5qhPc6Y3NT66qaGGA5or6as0i0JloLAYODiHcoztD+seWyExpVHM4ls=

A 403 error usually indicates a problem with your AWS credentials. What credentials are you using with your AmazonS3 object? By default, they'll be located in ~/.aws/credentials .

You can verify credentials are correct with the aws command-line tool. If you haven't used it before, run aws configure and enter your creds. Then you can attempt to upload a file with aws s3 cp somefile s3://mybucket .

If that succeeds, you can enable the Java SDK logging as documented here to get more information.
