Objects: insert | Cloud Storage | Google Cloud Documentation (original) (raw)
Stores a new object and metadata. The uploaded object replaces any existing object with the same name. For an overview of uploading to Cloud Storage, seeUploads and downloads. For examples of performing object uploads with different Cloud Storage tools and client libraries, see theUploading Objects guide.
This method accepts uploaded object data with the following characteristics:
- Maximum file size: 5 TiB
- Accepted Media MIME types:
*/*
This method generally requires the following headers be included in a request:
Note: Metadata-only requests are not allowed. To change an object's metadata, use the patch method.
Required permissions
The authenticated user must have the storage.objects.create IAM permission to use this method. If the object being inserted has the same name as an existing object, the user must also have the storage.objects.delete permission to overwrite the existing object. If the request body includes the retention property, the authenticated user must also have the storage.objects.setRetention IAM permission. If the request body includes a non-empty contexts.custom property, the authenticated user must also have the storage.objects.createContext IAM permission.
Request
HTTP request
Note: The request endpoint for this method differs from typical Cloud Storage JSON API endpoints.
POST https://storage.googleapis.com/upload/storage/v1/b/bucket/o
In addition to standard query parameters, the following query parameters apply to this method. Note that forresumable uploads, these headers can be used in the initial POST request but are ignored in the subsequent PUT requests.
To see an example of how to include query parameters in a request, see theJSON API Overview page.
Parameters
| Parameter name | Value | Description |
|---|---|---|
| Path parameters | ||
| bucket | string | Name of the bucket in which to store the new object. Overrides the provided object metadata's bucket value, if any. |
| Required query parameters | ||
| name | string | Name of the object. Not required if the request body contains object metadata that includes a name value. Overrides the object metadata's name value, if any. For information about how to URL encode object names to be path safe, seeEncoding URI path parts. |
| uploadType | string | The type of upload request to the**/upload** URI. Acceptable values are: media - Data-only upload. Upload the object data only, without any metadata. multipart - Multipart upload. Upload both the object data and its metadata, in a single request. resumable - Resumable upload. Upload the object data in a resumable fashion, using a series of at least two requests where the first request includes the metadata. |
| Optional query parameters | ||
| contentEncoding | string | If set, sets the contentEncoding property of the final object to this value. Setting this parameter is equivalent to setting the contentEncoding metadata property. This can be useful when uploading an object with uploadType=media to indicate the encoding of the content being uploaded. |
| ifGenerationMatch | long | Makes the operation conditional on whether the object's current generation matches the given value. Setting to 0 makes the operation succeed only if there are no live versions of the object. For more information, seeRequest preconditions. |
| ifGenerationNotMatch | long | Makes the operation conditional on whether the object's current generation does not match the given value. If no live object exists, the precondition fails. Setting to 0 makes the operation succeed only if there is a live version of the object. For more information, seeRequest preconditions. |
| ifMetagenerationMatch | long | Makes the operation conditional on whether the object's current metageneration matches the given value. For more information, seeRequest preconditions. |
| ifMetagenerationNotMatch | long | Makes the operation conditional on whether the object's current metageneration does not match the given value. For more information, seeRequest preconditions. |
| kmsKeyName | string | Resource name of the Cloud KMS key that will be used to encrypt the object. If not specified, the request uses the bucket's default Cloud KMS key, if any, or else it usesstandard Cloud Storage encryption. |
| predefinedAcl | string | Apply a predefined set of access controls to this object.Acceptable values are: authenticatedRead: Object owner gets OWNER access, andallAuthenticatedUsers get READER access. bucketOwnerFullControl: Object owner gets OWNER access, and project team owners get OWNER access. bucketOwnerRead: Object owner gets OWNER access, and project team owners get READER access. private: Object owner gets OWNER access. projectPrivate: Object owner gets OWNER access, and project team members get access according to their roles. publicRead: Object owner gets OWNER access, andallUsers get READER access. If iamConfiguration.uniformBucketLevelAccess.enabled is set totrue, requests that include this parameter fail with a400 Bad Request response. |
| projection | string | Set of properties to return. Defaults to noAcl, unless the object resource specifies the acl property, when it defaults to full.Acceptable values are: full: Include all properties. noAcl: Omit the owner, acl property. |
| Optional extension headers | ||
| X-Goog-Encryption-Algorithm | string | The encryption algorithm to use, which must be AES256. Used when encrypting the uploaded object with a customer-supplied encryption key. |
| X-Goog-Encryption-Key | string | An RFC 4648 Base64-encoded string of your AES-256 encryption key. Used when encrypting the uploaded object with a customer-supplied encryption key. |
| X-Goog-Encryption-Key-Sha256 | string | An RFC 4648 Base64-encoded string of the SHA256 hash of your encryption key. Used when encrypting the uploaded object with a customer-supplied encryption key. |
| X-Goog-Meta-KEY | string | Applicable only when used the final request of aresumable upload. An optional way to setcustom metadata for the uploaded object. |
Request body
When performing a simple upload, provide the object data in the request body. When performing amultipart upload or when initiating a resumable upload, both of which allow you to include object metadata as part of the request, supply the following properties. If you do not wish to provide object metadata in a resumable upload, the request body can be empty.
| Property name | Value | Description | Notes |
|---|---|---|---|
| Optional Properties | |||
