JSON Encoding a map in Elixir using Poison

Question

I'm trying to parse my map into a json string, how would i do that using poison? I've tried the following. ``` iex(19)> test = %{"api_key" => "sklfjklasfj"} %{"api_key" => "sklfjklasfj"} iex(20)> Poison.Encoder.encode(test, []) [123, [[34, ["api_key"], 34], 58, [34, ["sklfjklasfj"], 34]], 125] ``` What i would expect was ``` "{"api_key": "sklfjklasfj"}" ```

Accepted Answer

I realised poison was returning a char_list, which can be casted to a string like so.

```
iex(27)> to_string Poison.Encoder.encode(test, [])
"{\"api_key\":\"sklfjklasfj\"}"
```

As of October 2017 (Poison v3), the code would be

```
iex(27)> to_string Poison.encode_to_iodata!(test, [])
"{\"api_key\":\"sklfjklasfj\"}"
```

or simply

```
iex(27)> Poison.encode!(test, [])
"{\"api_key\":\"sklfjklasfj\"}"
```

without the `to_string` call.
