# spacepy.toolbox.get_url

spacepy.toolbox.get_url(url, outfile=None, reporthook=None, cached=False, keepalive=False, conn=None)

  Read data from a URL

  Open an HTTP URL, honoring the user agent as specified in the SpacePy config file. Returns the data, optionally also writing out to a file.

  This is similar to the deprecated `urlretrieve`.

  Parameters
    url str

      The URL to open

    outfile str (optional)

      Full path to file to write data to

    reporthook callable (optional)

      Function for reporting progress; takes arguments of block count, block size, and total size.

    cached bool (optional)

      Compare modification time of the URL to the modification time of `outfile`; do not retrieve (and return None) unless the URL is newer than the file.

    keepalive bool (optional)

      Attempt to keep the connection open to retrieve more URLs. The return becomes a tuple of (data, conn) to return the connection used so it can be used again. This mode does not support proxies. (Default False)

    conn http.client.HTTPConnection (optional)

      An established http connection (HTTPS is also okay) to use with `keepalive`. If not provided, will attempt to make a connection.

  Returns
    bytes

      The HTTP data from the server.

  Notes

  This function honors proxy settings as described in `urllib.request.getproxies()`. Cryptic error messages (such as `Network is unreachable`) may indicate that proxy settings should be defined as appropriate for your environment (e.g. with `HTTP_PROXY` or `HTTPS_PROXY` environment variables).
