AWS에 대한 Base64Encode가 Amazon과 일치하지 않습니다. 예 :

Question

아마존 S3 브라우저 기반 업로드를위한 첫 번째 장애물에서 실패한 것 같습니다.

아마존의 예는 여기에 표시된 사용 : http://docs.aws.amazon.com/AmazonS3/latest/API/sigv4-post-example.html

그루비/자바를 사용하여, 나는 예를 들어 포스트 정책을 인코딩하고 아마존과 같은 인코딩을 만들어 드릴 수 없습니다.

{ "expiration": "2015-12-30T12:00:00.000Z", 
    "conditions": [ 
    {"bucket": "sigv4examplebucket"}, 
    ["starts-with", "$key", "user/user1/"], 
    {"acl": "public-read"}, 
    {"success_action_redirect": "http://sigv4examplebucket.s3.amazonaws.com/successful_upload.html"}, 
    ["starts-with", "$Content-Type", "image/"], 
    {"x-amz-meta-uuid": "14365123651274"}, 
    {"x-amz-server-side-encryption": "AES256"}, 
    ["starts-with", "$x-amz-meta-tag", ""], 

    {"x-amz-credential": "AKIAIOSFODNN7EXAMPLE/20151229/us-east-1/s3/aws4_request"}, 
    {"x-amz-algorithm": "AWS4-HMAC-SHA256"}, 
    {"x-amz-date": "20151229T000000Z" } 
    ] 
} 

나는이 멋져요 멀티 라인 문자열로 정의했습니다 :

String policy_document = ''' 
{ "expiration": "2015-12-30T12:00:00.000Z", 
    "conditions": [ 
    {"bucket": "sigv4examplebucket"}, 
    ["starts-with", "$key", "user/user1/"], 
    {"acl": "public-read"}, 
    {"success_action_redirect": "http://sigv4examplebucket.s3.amazonaws.com/successful_upload.html"}, 
    ["starts-with", "$Content-Type", "image/"], 
    {"x-amz-meta-uuid": "14365123651274"}, 
    {"x-amz-server-side-encryption": "AES256"}, 
    ["starts-with", "$x-amz-meta-tag", ""], 

    {"x-amz-credential": "AKIAIOSFODNN7EXAMPLE/20151229/us-east-1/s3/aws4_request"}, 
    {"x-amz-algorithm": "AWS4-HMAC-SHA256"}, 
    {"x-amz-date": "20151229T000000Z" } 
    ] 
} 
''' 

나는 다음 인코딩 및 실패 어설으로 확인하고있다.

다음은 Java에서 잘되었습니다. 캐리지 리턴 및 줄 바꿈 위치는 그대로 두십시오.

String policy_document = "{ \"expiration\": \"2015-12-30T12:00:00.000Z\",\n" + 
      " \"conditions\": [\n" + 
      " {\"bucket\": \"sigv4examplebucket\"},\n" + 
      " [\"starts-with\", \"$key\", \"user/user1/\"],\n" + 
      " {\"acl\": \"public-read\"},\n" + 
      " {\"success_action_redirect\": \"http://sigv4examplebucket.s3.amazonaws.com/successful_upload.html\"},\n" + 
      " [\"starts-with\", \"$Content-Type\", \"image/\"],\n" + 
      " {\"x-amz-meta-uuid\": \"14365123651274\"},\n" + 
      " {\"x-amz-server-side-encryption\": \"AES256\"},\n" + 
      " [\"starts-with\", \"$x-amz-meta-tag\", \"\"],\n" + 
      "\n" + 
      " {\"x-amz-credential\": \"AKIAIOSFODNN7EXAMPLE/20151229/us-east-1/s3/aws4_request\"},\n" + 
      " {\"x-amz-algorithm\": \"AWS4-HMAC-SHA256\"},\n" + 
      " {\"x-amz-date\": \"20151229T000000Z\" }\n" + 
      " ]\n" + 
      "}"; 
    String base64Policy = (new BASE64Encoder()).encode(policy_document.getBytes()); 

Answer 2

나를 올바른 방향으로 안내해 주셔서 감사합니다.

마지막 해결책은 각 줄의 끝에이 순서대로 \ r \ n을 추가하는 것입니다.

String policy_document = "{ \"expiration\": \"2015-12-30T12:00:00.000Z\",\r\n" + 
     " \"conditions\": [\r\n" + 
     " {\"bucket\": \"sigv4examplebucket\"},\r\n" + 
     " [\"starts-with\", \"$key\", \"user/user1/\"],\r\n" + 
     " {\"acl\": \"public-read\"},\r\n" + 
     " {\"success_action_redirect\": \"http://sigv4examplebucket.s3.amazonaws.com/successful_upload.html\"},\r\n" + 
     " [\"starts-with\", \"$Content-Type\", \"image/\"],\r\n" + 
     " {\"x-amz-meta-uuid\": \"14365123651274\"},\r\n" + 
     " {\"x-amz-server-side-encryption\": \"AES256\"},\r\n" + 
     " [\"starts-with\", \"$x-amz-meta-tag\", \"\"],\r\n" + 
     "\r\n" + 
     " {\"x-amz-credential\": \"AKIAIOSFODNN7EXAMPLE/20151229/us-east-1/s3/aws4_request\"},\r\n" + 
     " {\"x-amz-algorithm\": \"AWS4-HMAC-SHA256\"},\r\n" + 
     " {\"x-amz-date\": \"20151229T000000Z\" }\r\n" + 
     " ]\r\n" + 
     "}"; 

이 너무 엄격하고 마크 업 청소기를 유지하기 위해이 작업을 수행 할 수없는 그루비 멀티 라인 문자열을 사용하는 것을 구현해야 할 것은 불행한 일입니다.
