使用unicode編碼json使用毒物

Question

我使用HTTPoison來獲取elixir指南網站，然後使用Floki解析它以構建一個HTML 2 Jupyter Notebook變壓器（使用Markdown作爲描述）。我必須投入「反撥」。用於代碼突出顯示的\u0060，迄今爲止工作。我有一些地方使用字符串插值和其他位置Enum.join ""來處理和轉換HTML到Markdown。

根據jupyter notebookformat將轉換後的結果存儲在地圖中。當我撥打Poison.encode notebook時，我收到一個錯誤消息，因爲代碼點消失了。我嘗試過不同的事情，但還不知道問題出在哪裏。

任何提示我在處理文本時做錯了什麼？這是個例外：

** (Poison.EncodeError) unable to encode value: {:source, ["Elixir also provides `Port`, `Reference` and `PID` as data types (usually used in process communication), and we will take a quick look at them when talking about processes. For now, let’s take a look at some of the basic operators that go with our basic types."]}

這裏的問題是，你正試圖編碼Tuple，而毒只能用地圖和列表的作品。如果您試圖編碼的值是一個Map而不是一個元組，它將完美工作。 Unicode與此無關。

iex(1)> value = %{source: ["Elixir also provides `Port`, `Reference` and `PID` as data types (usually used in process communication), and we will take a quick look at them when talking about processes. For now, let’s take a look at some of the basic operators that go with our basic types."]} 
iex(2)> Poison.encode(value) 
{:ok, 
"{\"source\":[\"Elixir also provides `Port`, `Reference` and `PID` as data types (usually used in process communication), and we will take a quick look at them when talking about processes. For now, let’s take a look at some of the basic operators that go with our basic types.\"]}"}
