To perform a single-request upload with the XML API, you make a
that is scoped with a bucket name and the object's name, and you put the object
data into the request body. The uploaded object replaces any existing object
with the same name. For tips on uploading to Cloud Storage, see
Best Practices. For a quick guide to simple uploads using tools such as
the XML API, see Uploading Objects.
The PUT Object request uses several standard HTTP headers.
specifies the object's size in bytes and is required unless you are using
chunked transfer encoding. Optional headers include
Content-MD5, and those listed below. Cloud Storage stores these
headers as part of the object's metadata, except for
Cloud Storage uses to check for data integrity. See
Editing object metadata for information on changing metadata values for
You also use a PUT Object request when you want to change the storage class
of an existing object, because you must rewrite the existing object to do so.
The request should contain the
x-goog-storage-class request header,
as well as the object in the request body.
Query string parameters
This request does not typically include query string parameters.
In addition to common request headers, the following can be used.
||The conditions under which a publicly accessible object should be
||A header that specifies presentational information about how the object data is to be transmitted.||No|
||The compression algorithm that was used to compress the object you are uploading.||No|
||The ISO 639-1 language code of the content.||No|
||The predefined ACL that you want to apply to the object.||No|
||A user-specified date and time.||No|
||The customer-managed encryption key to use to encrypt the object.||No|
||An extension header that can be used to store custom metadata.||No|
||A valid storage class.||No|
To provide a customer-supplied encryption key along with the object upload, use the headers listed on the Customer-Supplied Encryption Key page in your request.
Request body elements
The request body contains the data.
The following syntax applies to PUT Object requests that don't use any query
string parameters and excludes the
PUT /OBJECT_NAME HTTP/1.1 Host: BUCKET_NAME.storage.googleapis.com Date: DATE Content-Length: REQUEST_BODY_LENGTH Content-Type: MIME_TYPE Content-MD5: MD5_DIGEST Authorization: AUTHENTICATION_STRING x-goog-storage-class: STORAGE_CLASS
The request can return a variety of response headers depending on the request headers you use.
Response body elements
The response does not include an XML document in the response body.
The following sample uploads an object named paris.jpg to a bucket named travel-maps.
PUT /paris.jpg HTTP/1.1 Host: travel-maps.storage.googleapis.com Date: Sat, 20 Feb 2010 16:31:08 GMT Content-Type: image/jpg Content-MD5: iB94gawbwUSiZy5FuruIOQ== Content-Length: 554 Authorization: Bearer ya29.AHES6ZRVmB7fkLtd1XTmq6mo0S1wqZZi3-Lh_s-6Uw7p8vtgSwg

NoSuchBucket in the
If the supplied MD5 digest is malformed, you get a 400 Bad Request status
code and the body of the error response has
