/**
*
* Uploads a new object to the specified Qcloud COS bucket. The PutObjectRequest
* optionally uploads object metadata and applies a canned access control policy
* to the new object.
*
*
* Qcloud COS never stores partial objects; if during this call an exception
* wasn't thrown, the entire object was stored.
*
*
* 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. Qcloud COS uses
* checksums to validate the data in each file.
* -
* Using the file extension, Qcloud COS attempts to determine the correct content
* type and content disposition to use for the object.
*
*
* When uploading directly from an input stream, content length must be
* specified before data can be uploaded to Qcloud COS. If not provided, the
* library will have to buffer the contents of the input stream in order
* to calculate it. Qcloud COS explicitly requires that the content length be
* sent in the request headers before any of the data is sent.
*
* Qcloud COS is a distributed system. If Qcloud COS 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.
*
*
* Note: Qcloud COS does not provide object locking; if this is needed, make sure
* to build it into the application layer.
*
*
* If the caller specifies a location constraint when creating a bucket, all
* objects added to the bucket are stored in the same region as the bucket. For
* example, if specifying a Europe (EU) region constraint for a bucket, all of
* that bucket's objects are stored in the EU region.
*
*
* The specified bucket must already exist and the caller must have
* {@link Permission#Write} permission to the bucket to upload an object.
*
*
* @see PutObjectRequest#PutObjectRequest(String, String, File)
* @see PutObjectRequest#PutObjectRequest(String, String, InputStream,
* ObjectMetadata)
