Converting a map into a URI query string

Question

I have an Elixir Map:

m1 = %{a: 1, b: "fsfd", c: 123}

I want to convert it into a query string for URI.

a=1&b=fsfd&c=123

How can I do that? I've tried this:

Enum.reduce(m1, fn({k, v}, acc) -> "#{acc}&{k}=#{v}" end)

But it didn't work, because the acc didn't get pattern matched as intended.

You can use this:

URI.encode_query(%{a: 1, b: 2, c: "fdsfds"})
