    # array. We then scan the string for %d and %s to find the number of times
    # we possibly need to insert keys into the URI. Next, we check the size of
    # the keys array, if the keys size is less than the number of possible keys
    # in the URI, we will remove the trailing %d or %s, then remove the
    # trailing /. We then pass the keys into the uri to form the path.
    # ex. foo/%d/bar/%d => foo/1/bar/2
