Cloud Object Storage Upload Part - Copy-Object APIs-APIs-Tencent Cloud

Feature Overview
This API is used to copy the parts of an object from the source path to the destination path. You can use x-cos-copy-source to specify the source object and use x-cos-copy-source-range to specify the byte range to copy (each part should be 1 MB to 5 GB).
Note
The following two types of accounts can call this API:
Have the root account permissions.
Have the GetObjecet API permission of the source object and the InitiateMultipartUpload, ListMultipartUploads, ListParts, PutObject, CompleteMultipartUpload, and AbortMultipartUpload API permissions under the destination path.
Note
To call this API, you need to first call the Initiate Multipart Upload API to initialize the multipart upload and specify the destination path.
If the source and destination objects reside in two different regions and the part size is larger than 5 GB, use the multipart upload or multipart copy API to copy the object.
To upload an object in parts, you must first initialize the multipart upload. The response of the multipart upload initialization will include a unique descriptor uploadId, which needs to be carried in the multipart upload request.
﻿
Versioning
If versioning is enabled for the bucket, x-cos-copy-source identifies the current version of the object to copy. If the current version is a delete marker and no version is specified in x-cos-copy-source, COS will consider that the object has been deleted and return a 404 error. If you specify a versionId in x-cos-copy-source and the versionId is a delete marker, COS will return an HTTP 400 error as delete markers cannot be set in x-cos-copy-source.

Note
Host: <BucketName-APPID>.cos.<Region>.myqcloud.com, where <BucketName-APPID> is the bucket name with the APPID suffix, such as examplebucket-1250000000. You can refer to the Bucket Overview > Basic Information and Bucket Overview > Bucket Naming Convention documentation. <Region> represents the available regions for COS, which can be found in the Regions and Access Domain Names documentation.

Request Header
Common Header
This API uses common request headers. For more information, see Common Request Headers.
Non-common Header
Required headers
This API uses the following required header:
Name
Description
Local Disk Types
Required
x-cos-copy-source
URL of the source object. You can use versionid to specify the versionId of the object.
String
Required
Recommended headers
This API uses the following recommended headers:
Name
Description
Local Disk Types
Required
x-cos-copy-source-range
Byte range of the source object, specified in the format bytes=first-last, where first and last are zero-based offsets.
For example, bytes=0-9 indicates that you want to copy the first 10 bytes of the source object. If not specified, the entire object will be copied.
String
Not required
x-cos-copy-source-If-Modified-Since
Perform the operation if the Object has been modified after the specified time; otherwise, return a 412 status code.
Can be used in conjunction with x-cos-copy-source-If-None-Match. When combined with other conditions, it may result in conflicts.
String
Not required
x-cos-copy-source-If-Unmodified-Since
Perform the operation if the Object has not been modified after the specified time; otherwise, return a 412 status code.
Can be used in conjunction with x-cos-copy-source-If-Match. When combined with other conditions, it may result in conflicts.
String
Not required
x-cos-copy-source-If-Match
Perform the operation if the Object's Etag matches the given value; otherwise, return a 412 status code.
Can be used in conjunction with x-cos-copy-source-If-Unmodified-Since. When combined with other conditions, it may result in conflicts.
String
Not required
x-cos-copy-source-If-None-Match
Perform the operation if the Object's Etag does not match the given value; otherwise, return a 412 status code.
Can be used in conjunction with x-cos-copy-source-If-Modified-Since. When combined with other conditions, it may result in conflicts.
String
Not required
Request Parameters
Name
Description
Local Disk Types
Required
partNumber
Part number
String
Required
uploadId
To copy an object part, you must first initialize a multipart upload, after which a unique upload ID will be returned. This ID is required in the copy request.
String
Required
Request Body
The request body of this request is empty.

Special Response Header
Name                                           
Description
Local Disk Types
x-cos-copy-source-version-id
Version ID of the source object to copy (if versioning is enabled for the source bucket)
String
x-cos-server-side-encryption
If the object is stored with COS-managed server-side encryption, the response will contain this header and the encryption algorithm used (AES256).
String
Response Body
The return of this response body is application/xml data. Below is an example containing all the node data:
<?xml version="1.0" encoding="UTF-8" ?>
