uri_parser – Tools to parse and validate a MongoDB URI

Tools to parse and validate a MongoDB URI.

pymongo.uri_parser.parse_host(entity, default_port=27017)

Validates a host string

Returns a 2-tuple of host followed by port where port is default_port if it wasn’t specified in the string.

  • entity - A host or host:port string where host could be a hostname or IP address.
  • default_port - The port number to use when one wasn’t specified in entity.
pymongo.uri_parser.parse_ipv6_literal_host(entity, default_port)

Validates an IPv6 literal host:port string.

Returns a 2-tuple of IPv6 literal followed by port where port is default_port if it wasn’t specified in entity.

  • entity - A string that represents an IPv6 literal enclosed in braces (e.g. ‘[::1]’ or ‘[::1]:27017’).
  • default_port - The port number to use when one wasn’t specified in entity.
pymongo.uri_parser.parse_uri(uri, default_port=27017, validate=True)

Parse and validate a MongoDB URI.

Returns a dict of the form:

{
    'nodelist': <list of (host, port) tuples>,
    'username': <username> or None,
    'password': <password> or None,
    'database': <database name> or None,
    'collection': <collection name> or None,
    'options': <dict of MongoDB URI options>
}
  • uri - The MongoDB URI to parse.
  • default_port - The port number to use when one wasn’t specified for a host in the URI.
  • validate - If True (the default), validate and normalize all options.
pymongo.uri_parser.parse_userinfo(userinfo)

Validates the format of user information in a MongoDB URI. Reserved characters like ‘:’, ‘/’, ‘+’ and ‘@’ must be escaped following RFC 2396.

Returns a 2-tuple containing the unescaped username followed by the unescaped password.

  • userinfo - A string of the form <username>:<password>
pymongo.uri_parser.split_hosts(hosts, default_port=27017)

Takes a string of the form host1[:port],host2[:port]… and splits it into (host, port) tuples. If [:port] isn’t present the default_port is used.

Returns a set of 2-tuples containing the host name (or IP) followed by port number.

  • hosts - A string of the form host1[:port],host2[:port],…
  • default_port - The port number to use when one wasn’t specified for a host.
pymongo.uri_parser.split_options(opts, validate=True)

Takes the options portion of a MongoDB URI, validates each option and returns the options in a dictionary.

  • opt - A string representing MongoDB URI options.
  • validate - If True (the default), validate and normalize all options.
pymongo.uri_parser.validate_options(opts)

Validates and normalizes options passed in a MongoDB URI.

Returns a new dictionary of validated and normalized options.

  • opts - A dict of MongoDB URI options.
