如何使用JSON /字符串在Android上执行胡子模板？ [英] How to execute Mustache template with JSON/String on Android?

问题描述

结果
我有字符串与模板的基本对象，是这样的：

I have String object with template base, something like:

<h1>{{header}}</h1>
{{#bug}}
{{/bug}}

{{#items}}
  {{#first}}
    <li><strong>{{name}}</strong></li>
  {{/first}}
  {{#link}}
    <li><a href="{{url}}">{{name}}</a></li>
  {{/link}}
{{/items}}

{{#empty}}
  <p>The list is empty.</p>
{{/empty}}

我要拉另一个字符串对象重新presenting 的JSONObject 键，把它的领域为模板：

I want to pull another String object representing JSONObject and put its fields into template:

{
  "header": "Colors",
  "items": [
      {"name": "red", "first": true, "url": "#Red"},
      {"name": "green", "link": true, "url": "#Green"},
      {"name": "blue", "link": true, "url": "#Blue"}
  ],
  "empty": false
}

在最后，我会得到字符串重新presenting HTML结构：

In the end I would get String representing HTML structure:

<h1>Colors</h1>
<li><strong>red</strong></li>
<li><a href="#Green">green</a></li>
<li><a href="#Blue">blue</a></li>

我不希望使用任何的POJO或地图秒 - 只使用标准的字符串对象或交替转换第二个字符串到的JSONObject 来使用它作为一个模板的上下文。结果
可能有人给我任何例子，如何实现呢？结果
谢谢。

I don't want to use any POJOs or Maps - only use standard String objects or alternatively convert second String into JSONObject to use it as a template's context.
Could someone give me any example how to achieve that?
Thanks.

修改：我不知道模板/ JSON 任何结构在执行模板 - 我有未知的模板，播放/ JSON ，并认为他们是正确的。

Edit: I don't know anything about template/JSON structure while executing template - I have to play with unknown template/JSON and assume that they are correct.

推荐答案

我找不到办法​​纯字符串对象的工作 - 我转换的JSONObject 到地图来得到它与小胡子的工作。这是code转换：

I couldn't find way to work on pure String objects - I am converting JSONObject to Map to get it working with Mustache. This is code for conversion:

public static Map<String, Object> toMap(JSONObject object) throws JSONException
{
    Map<String, Object> map = new HashMap();
    Iterator keys = object.keys();
    while (keys.hasNext())
    {
        String key = (String) keys.next();
        map.put(key, fromJson(object.get(key)));
    }
    return map;
}

public static List toList(JSONArray array) throws JSONException
{
    List list = new ArrayList();
    for (int i = 0; i < array.length(); i++)
    {
        list.add(fromJson(array.get(i)));
    }
    return list;
}

private static Object fromJson(Object json) throws JSONException
{
    if (json instanceof JSONObject)
    {
        return toMap((JSONObject) json);
    } else if (json instanceof JSONArray)
    {
        return toList((JSONArray) json);
    } else
    {
        return json;
    }
}

用法：

mustacheTemplate.execute(JSONUtils.toMap(new JSONObject(myString)));
