```
    从接口复制的说明: COS
    Uploads a new object to the specified bucket. The PutObjectRequest contains all the details of the request, including the bucket to upload to, the key the object will be uploaded under, and the file or input stream containing the data to upload.
    
    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 method has slightly different behavior.
    
    When uploading a file:
    - The client automatically computes a checksum of the file. uses checksums to validate the data in each file.
    - Using the file extension, attempts to determine the correct content type and content disposition to use for the object.
    When uploading directly from an input stream:
    - Be careful to set the correct content type in the metadata object before directly sending a stream. Unlike file uploads, content types from input streams cannot be automatically determined. If the caller doesn't explicitly set the content type, it will not be set in .
    - Content length must be specified before data can be uploaded to . Qcloud COS explicitly requires that the content length be sent in the request headers before it will accept any of the data. If the caller doesn't provide the length, the library must buffer the contents of the input stream in order to calculate it.
    The specified bucket must already exist and the caller must have Permission#Write permission to the bucket to upload an object.
    指定者:
    
    putObject 在接口中 COS
    
    参数:
    putObjectRequest - The request object containing all the parameters to upload a new object to .

```
    从接口复制的说明: COS
    Gets the object stored in under the specified bucket and key.
    
    Be extremely careful when using this method; the returned COS object contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be closed until the user finishes reading the data and closes the stream. Therefore:
    - Use the data from the input stream in object as soon as possible
    - Close the input stream in object as soon as possible
    If these rules are not followed, the client can run out of resources by allocating too many open, but unused, HTTP connections.
    
    To get an object from , the caller must have Permission#Read access to the object.
    
    If the object fetched is publicly readable, it can also read it by pasting its URL into a browser.
    
    For more advanced options (such as downloading only a range of an object's content, or placing constraints on when the object should be downloaded) callers can use COS.getObject(GetObjectRequest).
    指定者:
    
    getObject 在接口中 COS
    
    参数:
    bucketName - The name of the bucket containing the desired object.
    key - The key under which the desired object is stored.

    抛出:

    Uploads a part in a multipart upload. You must initiate a multipart upload before you can upload any part.
    Your UploadPart request must include an upload ID and a part number. The upload ID is the ID returned by in response to your Initiate Multipart Upload request. Part number can be any number between 1 and 10,000, inclusive. A part number uniquely identifies a part and also defines its position within the object being uploaded. If you upload a new part using the same part number that was specified in uploading a previous part, the previously uploaded part is overwritten.
    To ensure data is not corrupted traversing the network, specify the Content-MD5 header in the Upload Part request. checks the part data against the provided MD5 value. If they do not match, returns an error.
    When you upload a part, the returned UploadPartResult contains an ETag property. You should record this ETag property value and the part number. After uploading all parts, you must send a CompleteMultipartUpload request. At that time constructs a complete object by concatenating all the parts you uploaded, in ascending order based on the part numbers. The CompleteMultipartUpload request requires you to send all the part numbers and the corresponding ETag values.
    Note: After you initiate a multipart upload and upload one or more parts, you must either complete or abort the multipart upload in order to stop getting charged for storage of the uploaded parts. Once you complete or abort the multipart upload will release the stored parts and stop charging you for their storage.

    从接口复制的说明: COS
    Returns a list of summary information about the objects in the specified bucket. Depending on the request parameters, additional information is returned, such as common prefixes if a delimiter was specified. List results are always returned in lexicographic (alphabetical) order.
    
    Because buckets can contain a virtually unlimited number of keys, the complete results of a list query can be extremely large. To manage large result sets, uses pagination to split them into multiple responses. Always check the ObjectListing.isTruncated() method to see if the returned listing is complete or if additional calls are needed to get more results. Alternatively, use the COS.listNextBatchOfObjects(ObjectListing) method as an easy way to get the next page of object listings.
    
    Calling ListObjectsRequest.setDelimiter(String) sets the delimiter, allowing groups of keys that share the delimiter-terminated prefix to be included in the returned listing. This allows applications to organize and browse their keys hierarchically, similar to how a file system organizes files into directories. These common prefixes can be retrieved through the ObjectListing.getCommonPrefixes() method.
    
    For example, consider a bucket that contains the following keys:
    - "foo/bar/baz"
    - "foo/bar/bash"
    - "foo/bar/bang"
    - "foo/boo"
    If calling listObjects with a prefix value of "foo/" and a delimiter value of "/" on this bucket, an ObjectListing is returned that contains one key ("foo/boo") and one entry in the common prefixes list ("foo/bar/"). To see deeper into the virtual hierarchy, make another call to listObjects setting the prefix parameter to any interesting common prefix to list the individual keys under that prefix.
    
    The total number of keys in a bucket doesn't substantially affect list performance.

    Sets the versioning configuration for the specified bucket.
    
    A bucket's versioning configuration can be in one of three possible states:
    By default, new buckets are in the off state. Once versioning is enabled for a bucket the status can never be reverted to off.
    
    Objects created before versioning was enabled or when versioning is suspended will be given the default null version ID (see Constants#NULL_VERSION_ID). Note that the null version ID is a valid version ID and is not the same as not having a version ID.
    
    The versioning configuration of a bucket has different implications for each operation performed on that bucket or for objects within that bucket. For example, when versioning is enabled a PutObject operation creates a unique object version-id for the object being uploaded. The The PutObject API guarantees that, if versioning is enabled for a bucket at the time of the request, the new object can only be permanently deleted using a DeleteVersion operation. It can never be overwritten. Additionally, the PutObject API guarantees that, if versioning is enabled for a bucket the request, no other object will be overwritten by that request. Refer to the documentation sections for each API for information on how versioning status affects the semantics of that particular API.

    Gets the AccessControlList (ACL) for the specified object in Qcloud COS.
    
    Each bucket and object in Qcloud COS has an ACL that defines its access control policy. When a request is made, Qcloud COS authenticates the request using its standard authentication procedure and then checks the ACL to verify the sender was granted access to the bucket or object. If the sender is approved, the request proceeds. Otherwise, Qcloud COS returns an error.
    
    指定者:
    
    getObjectAcl 在接口中 COS
    
    参数:
    getObjectAclRequest - the request object containing all the information needed for retrieving the object ACL.

    抛出:
