# Google Cloud Storage Transfer V1 Client - Class HttpData (2.4.0)

2.4.0 (latest) 2.3.2 2.2.1 2.1.1 2.0.2 1.5.0 1.4.5 1.3.1 1.2.0 1.1.1 1.0.6 Reference documentation and code samples for the Google Cloud Storage Transfer V1 Client class HttpData.

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](https://cloud.google.com/storage-transfer/docs/create-url-list). When transferring data based on a URL list, keep the following in mind:
- When an object located at `http(s)://hostname:port/<URL-path>` is transferred to a data sink, the name of the object at the data sink is `<hostname>/<URL-path>`.
- 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](https://docs.cloud.google.com/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](https://docs.cloud.google.com/php/docs/reference/cloud-storage-transfer/latest/V1.ObjectConditions) have no effect when filtering objects to transfer.
