View Source ExAws.JSON.Codec behaviour (ExAws v2.5.5)
Defines the specification for a JSON codec.
ExAws supports the use of your favorite JSON codec provided it fulfills this specification. Poison fulfills this spec without modification, and is the default.
See the contents of ExAws.JSON.JSX
for an example of an alternative implementation.
Example
Here for example is the code required to make jsx comply with this spec.
In your config you would do:
config :ex_aws,
json_codec: ExAws.JSON.JSX
defmodule ExAws.JSON.JSX do
@behaviour ExAws.JSON.Codec
@moduledoc false
def encode!(%{} = map) do
map |> :jsx.encode
end
def encode(map) do
try do
{:ok, encode!(map)}
rescue
ArgumentError -> {:error, :badarg}
end
end
def decode!(string) do
:jsx.decode(string, [:return_maps])
end
def decode(string) do
try do
{:ok, decode!(string)}
rescue
ArgumentError -> {:error, :badarg}
end
end
end
