二进制列表到字符串列表 - Erlang

Question

我如何转换[<<"a">>, <<"b">>, <<"c">>]为["a", "b", "c"]？

Answer 1

[binary_to_list(X) || X <- [<<"a">>, <<"b">>, <<"c">>]]. 或者更精细

BinList = [<<"a">>, <<"b">>, <<"c">>],
NormalList = [binary_to_list(X) || X <- BinList],
NormalList.

Answer 2

或者,使用列表:map/2:

lists:map(fun erlang:binary_to_list/1, [<<"a">>, <<"b">>, <<"c">>]).
