To upload an object, you make a PUT request that is scoped with a bucket name and the object's name, and you put the object data into the request body. For tips on uploading to Google Cloud Storage, see best practices.
The PUT Object request uses several standard HTTP headers. Content-Length
specifies the object's size in bytes and is required unless you are using
chunked transfer encoding. Optional headers include Cache-Control,
Content-Type, Content-Disposition, Content-MD5, x-goog-acl, and
x-goog-meta-. Cloud Storage stores these headers as part of the
object's metadata, except for Content-MD5, which Cloud Storage uses to
check for data integrity. See Editing object metadata for information on
changing metadata values for objects.
If you try to upload an object into a bucket that does not exist you
get a 404 Not Found status code
and the body of the error response has NoSuchBucket in the
Code element.
If the supplied MD5 digest is malformed you get a 400 Bad Request status code and the
body of the error response has InvalidDigest in the
Code element.
If the digest does not match the digest we compute from the body you get a
400 Bad Request status code
and the body of the error response has BadDigest in the
Code element.

The request body contains the data.
Request syntax
The following syntax applies to PUT Object requests that don't use any query
string parameters and excludes the x-goog-copy-source request
header.
PUT /<object> HTTP/1.1 Host: <bucket>.storage.googleapis.com Date: <date> Content-Length: <request body length> Content-Type: <MIME type> Content-MD5: <MD5 digest> Authorization: <authentication string> x-goog-acl: <predefined ACL>
Response headers
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.
Example
The following sample uploads an object named paris.jpg to a bucket named travel-maps.
