attribute to multipart/form-data
. After this, use HTML elements (such as <input> and <select>) to add form fields as needed.Field | Description | Type | Required |
key | Object key. If you use the ${filename} wildcard in the object key, the wildcard will be replaced with the name of the object uploaded (see Example 7). | string | Yes |
Cache-Control | Cache directives defined in RFC 2616. It will be stored as object metadata. | string | No |
Content-Disposition | Filename defined in RFC 2616. It will be stored as object metadata. | string | No |
Content-Encoding | Encoding format defined in RFC 2616. It will be stored as object metadata. | string | No |
Content-Type | HTTP content type (MIME) defined in RFC 2616. It will be stored as object metadata Note: If a file is uploaded via an HTML form, the browser will automatically carry the file's MIME type in the request. However, COS will not use this MIME type carried. Therefore, you need to use the Content-Type field to specify the content type of the object. | string | No |
Expires | Cache expiration time defined in RFC 2616. It will be stored as object metadata. | string | No |
success_action_redirect | Redirection target URL if the upload succeeds. If this field is set, HTTP status code "303 (Redirect)" and the Location response header will be returned. Location will include the URL specified in this field as well as the bucket, key, and ETag parameters (see Example 8). | string | No |
success_action_status | HTTP status code to return for a successful upload. Valid values: 200 , 201 , 204 (default). If success_action_redirect is specified, this field will be ignored (see Example 9). | number | No |
x-cos-meta-* | User-defined metadata and header suffixes. It will be stored as object metadata. Maximum size: 2 KB. Note: User-defined metadata can contain underscores (_), but header suffixes can contain minus signs (−) but not underscores. | string | No |
x-cos-storage-class | Object storage class. For the enumerated values, such as STANDARD (default), INTELLIGENT_TIERING , STANDARD_IA , ARCHIVE , and DEEP_ARCHIVE , see Storage Class Overview. | Enum | No |
x-cos-traffic-limit | Limits the speed (in bit/s) for the current upload for traffic control. Valid range: 819200−838860800 (i.e., 100 KB/s−100 MB/s). If the speed exceeds the limit, a 400 error will be returned. | integer | No |
Content-MD5 | MD5 checksum of the Base64-encoded file content. It is used for integrity check, i.e., whether the file content has changed during the upload. | string | No |
file | File information and content. When the file is uploaded via an HTML form, the browser automatically sets the value of this parameter to the correct format. Note: This field must be placed at the end of the form. | file | Yes |
Field | Description | Type | Required |
acl | Defines the ACL attribute of the object. For the enumerated values, such as default (default), private , and public-read , see the Preset ACL section in ACL Overview. Note: If you do not need to set an ACL for the object, set this parameter to default or leave it empty. In this way, the object will inherit the permissions of the bucket it is stored in. | Enum | No |
x-cos-grant-read | Grants a user permission to read the object in the format: id="[OwnerUin]" (e.g., id="100000000001" ). You can use comma (,) to separate multiple users, for example, id="100000000001",id="100000000002" . | string | No |
x-cos-grant-read-acp | Grants a user permission to read the ACL of an object in the format: id="[OwnerUin]" (e.g., id="100000000001" ). You can use comma (,) to separate multiple users, for example, id="100000000001",id="100000000002" . | string | No |
x-cos-grant-write-acp | Grants a user permission to write to the ACL of an object in the format: id="[OwnerUin]" (e.g., id="100000000001" ). You can use comma (,) to separate multiple users, for example, id="100000000001",id="100000000002" . | string | No |
x-cos-grant-full-control | Grants a user full permission to operate on an object in the format: id="[OwnerUin]" (e.g., id="100000000001" ). You can use comma (,) to separate multiple users, for example, id="100000000001",id="100000000002" . | string | No |
Field | Description | Type | Required |
x-cos-server-side-encryption | Server-side encryption algorithm. AES256 and cos/kms are supported. | string | Required if SSE-COS or SSE-KMS is used |
x-cos-server-side-encryption-customer-algorithm | Server-side encryption algorithm. AES256 is supported. | string | Required if SSE-C is used |
x-cos-server-side-encryption-cos-kms-key-id | Customer master key (CMK) of KMS if x-cos-server-side-encryption is set to cos/kms . If this field is not specified, the default CMK created by COS will be used. For more information, see SSE-KMS Encryption. | string | No |
x-cos-server-side-encryption-context | Base64-encoded encryption context (key-value pairs in JSON format) if x-cos-server-side-encryption is set to cos/kms . Example: eyJhIjoiYXNkZmEiLCJiIjoiMTIzMzIxIn0= | string | No |
