PUT Object - Copy

Last updated: 2024-09-26 16:50:11

Feature Overview
This API is used to create a copy of an object that already exists in COS, i.e., copying an object from the source path (object key) to the destination path (object key). The recommended object size is from 1 MB to 5 GB. For objects over 5 GB, refer to Upload Part - Copy.
You can specify how metadata is processed during the copy process. By default, the metadata will be copied to the destination object. You can also choose not to copy the metadata of the source object and specify new metadata in the API request. However, unless the storage class, access control list (ACL), and server-side encryption (SSE) are explicitly specified in the request, the storage class of the destination object will be STANDARD, the ACL of the destination bucket will be inherited, and SSE will not be used by default, regardless of the processing method.
You can use this API to move, rename, and copy object metadata and create copies.
To call this API, you need to have permission to read the object you want to copy, or the object must be set to public-read (i.e., everyone has read permission for the object). Besides, you must have write permission for the destination bucket.
Note: 
An error may be returned when COS receives the copy request or is copying the object. If an error occurs before the copy begins, a standard error response will be returned. If an error occurs during the copy, HTTP 200 OK will be returned with the error as the response body, meaning that the HTTP 200 OK response can include both success and error information. When using this API, pay attention to the content of the response body to determine whether the copy request was successful and process the result accordingly.
The MAZ_STANDARD storage class only supports replication into the exact same class rather than STANDARD, STANDARD_IA, or ARCHIVE storage classes.
The MAZ_STANDARD_IA storage class only supports replication into the exact same class rather than STANDARD, STANDARD_IA, or ARCHIVE storage classes.
Calling PUT Object - Copy is equivalent to requesting GET Object once in the source bucket and requesting PUT Object once in the destination bucket. Please note that this operation will incur charges for items such as read and write requests, storage usage, cross-region replication traffic, and data processing and moderation generated by workflows.
﻿
Versioning
If versioning is enabled for the bucket where the source object resides, the latest version of the source object is copied by default. You can specify the versionId parameter in the x-cos-copy-source request header to copy a specified version.
If versioning is enabled for the destination bucket, COS will automatically generate a unique version ID for the destination object.

Header
Description
Type
Required
x-cos-copy-source
URL of the source object, where the object key needs to pass through URLEncode. The version of the source object can be specified by the versionId parameter, such as sourcebucket-1250000001.cos.ap-shanghai.myqcloud.com/example-%E8%85%BE%E8%AE%AF%E4%BA%91.jpg, or sourcebucket-1250000001.cos.ap-shanghai.myqcloud.com/example-%E8%85%BE%E8%AE%AF%E4%BA%91.jpg?versionId=MTg0NDUxNzYzMDc0NDMzNDExOTc
string
Yes
x-cos-metadata-directive
Specifies whether to copy the metadata information of the source object. Enumerated values: Copy (default), Replaced.
If this parameter is set to Copy, the metadata information of the source object will be copied. 
If this parameter is set to Replaced, the metadata information in the request header will be used as the metadata information of the destination object.
If the destination and source objects are the same and you want to modify the metadata, this parameter must be set to Replaced.
Enum
No
x-cos-copy-source-If-Modified-Since
If the object is modified after the specified time, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.
string
No
x-cos-copy-source-If-Unmodified-Since
If the object is not modified after the specified time, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.
string
No
x-cos-copy-source-If-Match
If the ETag of the object is the same as the specified value, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.
string
No
x-cos-copy-source-If-None-Match
If the ETag of the object is not the same as the specified value, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.
string
No
x-cos-storage-class
Storage class of the destination object. For the enumerated values, such as INTELLIGENT_TIERING, MAZ_INTELLIGENT_TIERING, STANDARD_IA, ARCHIVE, and DEEP_ARCHIVE, see Storage Class Overview. Default value: STANDARD.
Enum
No
x-cos-tagging
A set of up to 10 object tags (for example, Key1=Value1&Key2=Value2). Tag key and tag value in the set must be URL-encoded.
string
No
x-cos-tagging-directive
Specifies whether to copy the tags of the source object. Enumerated values: Copy (default), Replaced.
If this parameter is set to Copy, tags of the source object will be copied.
If this parameter is set to Replaced, tags specified in the request header will be used for the destination object.
When the source and destination object is the same, that is, you want to modify the object tag, this parameter must be set to Replaced.
Enum
No
x-cos-forbid-overwrite
For a bucket which has never enabled versioning, you may use it to specify whether to prohibit overwriting the object with the same name when uploading the object:
When the x-cos-forbid-overwrite header is not specified or specified as false, the object with the same name will be overwritten by default;
When the x-cos-forbid-overwrite is specified as true, overwriting the object with the same name will be prohibited.          
Note：
For a bucket which has enabled versioning or suspended versioning, the x-cos-forbid-overwrite request header is invalid,  which means overwriting objects with the same name is allowed whether the x-cos-forbid-overwrite request header is specified as true or false.    
string
Not required
Headers related to destination object metadata
When copying an object, you can configure the metadata information of the destination object by specifying the following request headers.

Header	Description	Type	Required
x-cos-copy-source	URL of the source object, where the object key needs to pass through URLEncode. The version of the source object can be specified by the `versionId` parameter, such as `sourcebucket-1250000001.cos.ap-shanghai.myqcloud.com/example-%E8%85%BE%E8%AE%AF%E4%BA%91.jpg`, or `sourcebucket-1250000001.cos.ap-shanghai.myqcloud.com/example-%E8%85%BE%E8%AE%AF%E4%BA%91.jpg?versionId=MTg0NDUxNzYzMDc0NDMzNDExOTc`	string	Yes
x-cos-metadata-directive	Specifies whether to copy the metadata information of the source object. Enumerated values: `Copy` (default), `Replaced`. If this parameter is set to `Copy`, the metadata information of the source object will be copied. If this parameter is set to `Replaced`, the metadata information in the request header will be used as the metadata information of the destination object. If the destination and source objects are the same and you want to modify the metadata, this parameter must be set to `Replaced`.	Enum	No
x-cos-copy-source-If-Modified-Since	If the object is modified after the specified time, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.	string	No
x-cos-copy-source-If-Unmodified-Since	If the object is not modified after the specified time, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.	string	No
x-cos-copy-source-If-Match	If the `ETag` of the object is the same as the specified value, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.	string	No
x-cos-copy-source-If-None-Match	If the `ETag` of the object is not the same as the specified value, the copy operation will be executed; otherwise, an HTTP 412 status code (Precondition Failed) is returned.	string	No
x-cos-storage-class	Storage class of the destination object. For the enumerated values, such as `INTELLIGENT_TIERING`, `MAZ_INTELLIGENT_TIERING`, `STANDARD_IA`, `ARCHIVE`, and `DEEP_ARCHIVE`, see Storage Class Overview. Default value: `STANDARD`.	Enum	No
x-cos-tagging	A set of up to 10 object tags (for example, `Key1=Value1&Key2=Value2`). Tag key and tag value in the set must be URL-encoded.	string	No
x-cos-tagging-directive	Specifies whether to copy the tags of the source object. Enumerated values: `Copy` (default), `Replaced`. If this parameter is set to `Copy`, tags of the source object will be copied. If this parameter is set to `Replaced`, tags specified in the request header will be used for the destination object. When the source and destination object is the same, that is, you want to modify the object tag, this parameter must be set to `Replaced`.	Enum	No
x-cos-forbid-overwrite	For a bucket which has never enabled versioning, you may use it to specify whether to prohibit overwriting the object with the same name when uploading the object: When the x-cos-forbid-overwrite header is not specified or specified as false, the object with the same name will be overwritten by default; When the x-cos-forbid-overwrite is specified as true, overwriting the object with the same name will be prohibited. Note： For a bucket which has enabled versioning or suspended versioning, the x-cos-forbid-overwrite request header is invalid, which means overwriting objects with the same name is allowed whether the x-cos-forbid-overwrite request header is specified as true or false.	string	Not required
