/**
* Request class to upload a object to S3 using presigned urls. Upload content can be provided through a file or input stream.
*
* The behavior is similar to using {@link PutObjectRequest}. Depending on whether a file or input stream is being uploaded,
* this request has slightly different behavior.
*
*
* When uploading a file:
*
*
* -
* The client automatically computes a checksum of the file. Amazon S3 uses
* checksums to validate the data in each file.
* -
* Using the file extension, Amazon S3 attempts to determine the correct content
* type and content disposition to use for the object with some exceptions. See below.
*
* -
* If the given presigned url is created using SigV2 signer and content type is not provided,
* then SDK will not attempt to determine the content type and instead sends an empty string for content type.
* This is because content type is signed header in SigV2 and so the content type can only be sent
* if it is used in creating presigned url.
*
* -
* If the given presigned url is created using SigV4 signer, then SDK attempts to determine
* the correct content type and sends it with the request if not provided. Note that this only works
* if you have not used content type while creating the presigned url. If you have used content type while
* creating the url, then you should set the same content type while making this API call through
* {@link PresignedUrlUploadRequest#setMetadata(ObjectMetadata)} or
* {@link PresignedUrlUploadRequest#putCustomRequestHeader(String, String)}
*
*
*
* Amazon S3 is a distributed system. If Amazon S3 receives multiple write
* requests for the same object nearly simultaneously, all of the objects might
* be stored. However, only one object will obtain the key.
*
*
* If custom headers are used in generating the url, you can set them through {@link #putCustomRequestHeader(String, String)}
* method. If any signed headers or parameters are missing from the request, a Signature mismatch error will be thrown from S3.
* Ensure you set all the custom headers/parameters that are used for creating the presigned url.
