module: get_url
short_description: Downloads files from HTTP, HTTPS, or FTP to node
description:
     - Downloads files from HTTP, HTTPS, or FTP to the remote server. The remote
       server I(must) have direct access to the remote resource.
     - By default, if an environment variable E(<protocol>_proxy) is set on
       the target host, requests will be sent through that proxy. This
       behaviour can be overridden by setting a variable for this task
       (see R(setting the environment,playbooks_environment)),
       or by using the use_proxy option.
     - HTTP redirects can redirect from HTTP to HTTPS so you should be sure that
       your proxy environment for both protocols is correct.
     - From Ansible 2.4 when run with C(--check), it will do a HEAD request to validate the URL but
       will not download the entire file or verify it against hashes and will report incorrect changed status.
     - For Windows targets, use the M(ansible.windows.win_get_url) module instead.
version_added: '0.6'
options:
  ciphers:
    description:
      - SSL/TLS Ciphers to use for the request.
      - 'When a list is provided, all ciphers are joined in order with C(:).'
      - See the L(OpenSSL Cipher List Format,https://www.openssl.org/docs/manmaster/man1/openssl-ciphers.html#CIPHER-LIST-FORMAT)
        for more details.
      - The available ciphers is dependent on the Python and OpenSSL/LibreSSL versions.

      - HTTP, HTTPS, or FTP URL in the form C((http|https|ftp)://[user[:pass]]@host.domain[:port]/path).
    type: str
    required: true
  dest:
    description:
      - Absolute path of where to download the file to.
      - If O(dest) is a directory, either the server provided filename or, if
        none provided, the base name of the URL on the remote server will be
        used. If a directory, O(force) has no effect.
      - If O(dest) is a directory, the file will always be downloaded
        (regardless of the O(force) and O(checksum) option), but
        replaced only if the contents changed.
    type: path
    required: true
  tmp_dest:
    description:
      - Absolute path of where temporary file is downloaded to.
      - When run on Ansible 2.5 or greater, path defaults to ansible's C(remote_tmp) setting.
      - When run on Ansible prior to 2.5, it defaults to E(TMPDIR), E(TEMP) or E(TMP) env variables or a platform specific value.
      - U(https://docs.python.org/3/library/tempfile.html#tempfile.tempdir).
    type: path
    version_added: '2.1'
  force:
    description:
      - If V(true) and O(dest) is not a directory, will download the file every
        time and replace the file if the contents change. If V(false), the file
        will only be downloaded if the destination does not exist. Generally
        should be V(true) only for small local files.
      - Prior to 0.6, this module behaved as if V(true) was the default.
    type: bool
    default: no
    version_added: '0.7'
  backup:
    description:
      - Create a backup file including the timestamp information so you can get
        the original file back if you somehow clobbered it incorrectly.
    type: bool
    default: no
    version_added: '2.1'
  checksum:
    description:
      - 'If a checksum is passed to this parameter, the digest of the
        destination file will be calculated after it is downloaded to ensure
        its integrity and verify that the transfer completed successfully.
        Format: <algorithm>:<checksum|url>, for example C(checksum="sha256:D98291AC[...]B6DC7B97"),
        C(checksum="sha256:http://example.com/path/sha256sum.txt").'
      - If you worry about portability, only the sha1 algorithm is available
        on all platforms and python versions.
      - The Python C(hashlib) module is responsible for providing the available algorithms.
        The choices vary based on Python version and OpenSSL version.
      - On systems running in FIPS compliant mode, the C(md5) algorithm may be unavailable.
      - Additionally, if a checksum is passed to this parameter, and the file exist under
        the O(dest) location, the C(destination_checksum) would be calculated, and if
        checksum equals C(destination_checksum), the file download would be skipped
        (unless O(force=true)). If the checksum does not equal C(destination_checksum),
        the destination file is deleted.
      - If the checksum URL requires username and password, O(url_username) and O(url_password) are used
        to download the checksum file.
    type: str
    default: ''
    version_added: "2.0"
  use_proxy:
    description:
      - if V(false), it will not use a proxy, even if one is defined in
        an environment variable on the target hosts.
    type: bool
    default: yes
  validate_certs:
    description:
      - If V(false), SSL certificates will not be validated.
      - This should only be used on personally controlled sites using self-signed certificates.
    type: bool
    default: yes
  timeout:
    description:
      - Timeout in seconds for URL request.
    type: int
    default: 10
    version_added: '1.8'
  headers:
    description:
        - Add custom HTTP headers to a request in hash/dict format.
        - The hash/dict format was added in Ansible 2.6.
        - Previous versions used a C("key:value,key:value") string format.
        - The C("key:value,key:value") string format is deprecated and has been removed in version 2.10.
    type: dict
    version_added: '2.0'
  url_username:

    type: str

    version_added: '1.6'

    description:
        - The password for use in HTTP basic authentication.
        - If the O(url_username) parameter is not specified, the O(url_password) parameter will not be used.
        - Since version 2.8 you can also use the O(password) alias for this option.
    type: str
    aliases: ['password']
    version_added: '1.6'
  force_basic_auth:
    description:
      - Force the sending of the Basic authentication header upon initial request.
      - httplib2, the library used by the uri module only sends authentication information when a webservice
        responds to an initial request with a 401 status. Since some basic auth services do not properly
        send a 401, logins will fail.
    type: bool
    default: no
    version_added: '2.0'
  client_cert:
    description:
      - PEM formatted certificate chain file to be used for SSL client authentication.
      - This file can also include the key as well, and if the key is included, O(client_key) is not required.
    type: path

  client_key:
    description:

      - Header to identify as, generally appears in web server logs.

  unredirected_headers:
    description:
      - A list of header names that will not be sent on subsequent redirected requests. This list is case
        insensitive. By default all headers will be redirected. In some cases it may be beneficial to list
        headers such as C(Authorization) here to avoid potential credential exposure.

    version_added: '2.12'
  use_gssapi:
    description:
      - Use GSSAPI to perform the authentication, typically this is for Kerberos or Kerberos through Negotiate
        authentication.
      - Requires the Python library L(gssapi,https://github.com/pythongssapi/python-gssapi) to be installed.
      - Credentials for GSSAPI can be specified with O(url_username)/O(url_password) or with the GSSAPI env var
        E(KRB5CCNAME) that specified a custom Kerberos credential cache.
      - NTLM authentication is I(not) supported even if the GSSAPI mech for NTLM has been installed.
    type: bool
    default: no
    version_added: '2.11'
  use_netrc:
    description:
      - Determining whether to use credentials from C(~/.netrc) file.
      - By default C(.netrc) is used with Basic authentication headers.
      - When V(false), C(.netrc) credentials are ignored.
