public class PutObjectRequest extends AbstractPutObjectRequest implements Serializable
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:
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
Permission.Write permission to the bucket to upload an object.

PutObjectRequest object to upload a file to the
specified bucket and key. After constructing the request,
users may optionally specify object metadata or a canned ACL as well.bucketName - The name of an existing bucket to which the new object will be
uploaded.key - The key under which to store the new object.file - The path of the file to upload to Qcloud COS.public PutObjectRequest(String bucketName, String key, InputStream input, ObjectMetadata metadata)
PutObjectRequest object to upload a stream of data to
the specified bucket and key. After constructing the request,
users may optionally specify object metadata or a canned ACL as well.
Content length for the data stream must be specified in the object metadata parameter; Qcloud COS requires it be passed in before the data is uploaded. Failure to specify a content length will cause the entire contents of the input stream to be buffered locally in memory so that the content length can be calculated, which can result in negative performance problems.
