HttpData class
An HttpData resource specifies a list of objects on the web to be transferred over HTTP.
The information of the objects to be transferred is contained in a file
referenced by a URL. The first line in the file must be "TsvHttpData-1.0",
which specifies the format of the file. Subsequent lines specify the
information of the list of objects, one object per list entry. Each entry
has the following tab-delimited fields: * HTTP URL — The location of the
object. * Length — The size of the object in bytes. * MD5 — The
base64-encoded MD5 hash of the object. For an example of a valid TSV file,
see
Transferring data from URLs.
When transferring data based on a URL list, keep the following in mind: *
When an object located at http(s)://hostname:port/ is transferred to a
data sink, the name of the object at the data sink is /. * If the
specified size of an object does not match the actual size of the object
fetched, the object is not transferred. * If the specified MD5 does not
match the MD5 computed from the transferred bytes, the object transfer
fails. * Ensure that each URL you specify is publicly accessible. For
example, in Cloud Storage you can [share an object publicly]
(/storage/docs/cloud-console#_sharingdata) and get a link to it. * Storage
Transfer Service obeys robots.txt rules and requires the source HTTP
server to support Range requests and to return a Content-Length header
in each response. * ObjectConditions have no effect when filtering objects
to transfer.
