Question

我正在尝试将图像从base64解码为字节数组，然后加载到S3存储桶中。贝娄是我的代码，

 byte[] imagecontent = Base64.decodeBase64(IMMAGE_CONTENT);
if(imagecontent .length>0) {

       input = new ByteArrayInputStream(screenshot);    
       String file_name = "img_SOME_LOGIC.jpg";
       conn.putObject( this.bucketname, file_name, input, new ObjectMetadata());

}

以上代码对文本文档正常工作。意思是读取文本文件并上传。但是以上不适用于图像。
以下是我得到的错误

com.amazonaws.AmazonClientException: Unable to unmarshall error response (The declaration for the entity "ContentType" must end with '>'.)
    at com.amazonaws.http.AmazonHttpClient.handleErrorResponse(AmazonHttpClient.java:532)

    at com.amazonaws.services.s3.AmazonS3Client.putObject(AmazonS3Client.java:928)

你能帮我吗？
