The result is suitable for setting query params on an http request. .. code-block:: python >>> obj = {'a': ... {'b': ... {'c': ['x', 'y', 'z']} }, ... 'd': 'uvw', ... 'e': True, } >>> flatten_query_params(obj, strict=True) [('a.b.c', 'x'), ('a.b.c', 'y'), ('a.b.c', 'z'), ('d', 'uvw'), ('e', 'true')] Note that, as described in https://github.com/googleapis/googleapis/blob/48d9fb8c8e287c472af500221c6450ecd45d7d39/google/api/http.proto#L117, repeated fields (i.e. list-valued fields) may only contain primitive types (not lists or dicts). This is enforced in this function. Args: obj: a possibly nested dictionary (from json), or None strict: a bool, defaulting to False, to enforce that all values in the result tuples be strings and, if boolean, lower-cased. Returns: a list of tuples, with each tuple having a (possibly) multi-part name and a scalar value. Raises: TypeError if obj is not a dict or None ValueError if obj contains a list of non-primitive values.
