Java 在AWS s3中上载文件时，元数据道具显示访问被拒绝

我正在尝试将一个文件从Java代码上传到S3和CloudFront

public String uploadFile(String fileData, String fileName, String contentType, String extension){
        try {
            loggerUtils.log ("File Data" ,  fileData);
            byte[] bI = org.apache.commons.codec.binary.Base64.decodeBase64 ((fileData.substring (fileData.indexOf (",") + 1)).getBytes ());
            InputStream fis = new ByteArrayInputStream (bI);
            AmazonS3 s3 = new AmazonS3Client ();
            Region usWest02 = Region.getRegion (REGION);
            s3.setRegion (usWest02);
            ObjectMetadata metadata = new ObjectMetadata ();
            metadata.setContentLength (bI.length);
            metadata.setContentType (contentType + "/" + extension.substring (1));
            metadata.setCacheControl ("public, max-age=0");
            s3.putObject (BUCKET_NAME, fileName, fis, metadata);
            s3.setObjectAcl (BUCKET_NAME, fileName, CannedAccessControlList.PublicRead);
            URL s3Url = s3.getUrl(BUCKET_NAME, fileName);
            s3Url.toExternalForm();
            // return s3Url.toExternalForm();
            return uploadToCloudFront (fileName, bI).toExternalForm ();
        }
        catch (Exception exception){
            exception.printStackTrace ();
            loggerUtils.log (exception.toString ());
        }
        return null;
    }


public URL uploadToCloudFront(String fileName, byte[] imageByteArray) {
        URL url;
        try {
            String cloudFrontURL = "************.cloudfront.net";
            url = new URL("http://"+cloudFrontURL+ "/"+ fileName);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setRequestMethod("PUT");
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            connection.setRequestProperty("charset","UTF-8");
            connection.setRequestProperty("Content-Length", imageByteArray.length+"");
            DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
            wr.write(imageByteArray);
            wr.flush();
            wr.close();
            connection.disconnect();
            connection.getResponseCode();
            if(connection.getResponseCode () == 200) { return url; } else return null;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

如果我只是将文件上传到S3 Bucket，那么我的对象的元数据属性将显示正确的值

但是如果我在将文件上传到S3后尝试调用

uploadToCloudFront（）

，如代码所示。然后我的元数据道具显示访问被拒绝

是否有人在S3和CloudFront方面遇到过类似的问题

public String uploadFile(String fileData, String fileName, String contentType, String extension){
        try {
            loggerUtils.log ("File Data" ,  fileData);
            byte[] bI = org.apache.commons.codec.binary.Base64.decodeBase64 ((fileData.substring (fileData.indexOf (",") + 1)).getBytes ());
            InputStream fis = new ByteArrayInputStream (bI);
            AmazonS3 s3 = new AmazonS3Client ();
            Region usWest02 = Region.getRegion (REGION);
            s3.setRegion (usWest02);
            ObjectMetadata metadata = new ObjectMetadata ();
            metadata.setContentLength (bI.length);
            metadata.setContentType (contentType + "/" + extension.substring (1));
            metadata.setCacheControl ("public, max-age=0");
            s3.putObject (BUCKET_NAME, fileName, fis, metadata);
            s3.setObjectAcl (BUCKET_NAME, fileName, CannedAccessControlList.PublicRead);
            URL s3Url = s3.getUrl(BUCKET_NAME, fileName);
            s3Url.toExternalForm();
            // return s3Url.toExternalForm();
            return uploadToCloudFront (fileName, bI).toExternalForm ();
        }
        catch (Exception exception){
            exception.printStackTrace ();
            loggerUtils.log (exception.toString ());
        }
        return null;
    }


public URL uploadToCloudFront(String fileName, byte[] imageByteArray) {
        URL url;
        try {
            String cloudFrontURL = "************.cloudfront.net";
            url = new URL("http://"+cloudFrontURL+ "/"+ fileName);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setDoOutput(true);
            connection.setDoInput(true);
            connection.setRequestMethod("PUT");
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            connection.setRequestProperty("charset","UTF-8");
            connection.setRequestProperty("Content-Length", imageByteArray.length+"");
            DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
            wr.write(imageByteArray);
            wr.flush();
            wr.close();
            connection.disconnect();
            connection.getResponseCode();
            if(connection.getResponseCode () == 200) { return url; } else return null;
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
