Question

我使用HTTPoison获取elixir指南网站，然后使用Floki解析它以构建HTML 2 Jupyter Notebook变换器（使用Markdown作为描述）。我必须加入'反击。 \u0060代码突出显示，到目前为止有效。我有一些地方使用字符串插值"#{Floki.text(childs_nodes)}"和其他地方Enum.join ""来处理和转换从HTML到Markdown。

根据jupyter notebookformat将转换后的结果存储在地图中。当我调用Poison.encode notebook时，我收到错误，因为代码点消失了。我尝试了不同的东西，但还不知道，问题出在哪里。

在处理文本时，有什么提示我做错了什么？这是例外：

** (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."]}

问题在于您尝试对Tuple进行编码，而Poison仅适用于地图和列表。如果您尝试编码的值是地图而不是元组，它会很完美。 Unicode与此无关。

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.\"]}"}
