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.

Parameters:

• 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.

Parameters:

• 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>
}

Parameters:

• 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.

Paramaters:

• userinfo: A string of the form <username>:<password>

Changed in version 2.2: Now uses urllib.unquote_plus so + characters must be escaped.

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.

Parameters:

• 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.

Parameters:

• 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.

Parameters:

• opts: A dict of MongoDB URI options.
