Question

我将WordPress自定义帖子类型作为JSON Feed传递给我的应用。

我创建了一个JSON页面模板，用于查询和显示结果，如下所示：

$directories [] = array(
'subtype' => 'mcms',
'type' => 'maps', 
'summary' => get_the_title(),
'title' => get_the_title(),
'address' => get_field('address'),
'content' => get_the_content(),
'author' => get_the_author()
  );
endwhile;
wp_reset_query();
echo json_encode ($directories);

这个输出是：

[
{
"subtype": "mcms",
"type": "maps",
"summary": "Directory Listing",
"title": "Directory Listing",
"address": false,
"content": "Lorem ipsum dolor sit amet",
"author": "admin"
}
]

我想按如下方式格式化输出：

"items:" [
{
"subtype": "mcms",
"type": "maps",
"summary": "Directory Listing",
"title": "Directory Listing",
"address": false,
"content": "Lorem ipsum dolor sit amet",
"author": "admin"
}
]

我正在尝试以下方法：

 echo  "items: ", json_encode ($directories);

但输出不是我需要的JSON格式

任何帮助？

Answer 1

在致电$directories之前，将json_encode包裹在数组中。

$items = ['items' => $directories];

echo json_encode($items);

Answer 2

在数组中添加目录是解决方案：

echo json_encode（array（＆＃39; items＆＃39; =＆gt; $ directories））;

Answer 3

更改此行

$directories[] = array(...

到此

$directories['items'][] = array(...

你的回声就是这样的

echo json_encode($directories);

Answer 4

您可以使输出像这样：

[
    {
        "items:" [
            {
                "subtype": "mcms",
                "type": "maps",
                "summary": "Directory Listing",
                "title": "Directory Listing",
                "address": false,
                "content": "Lorem ipsum dolor sit amet",
                "author": "admin"
            }
        ]
     }
]

您需要为项目创建一个对象，然后创建一个哈希图

Map<String, List<KeyValue>> map = new HashMap();
map.put("items", itemObject);
JsonBuilderFactory jsnFactory = Json.createBuilderFactory(null);
JsonObjectBuilder builder = jsnFactory.createObjectBuilder();
for (String key : map.keySet()) {
    builder.add(keu,map.get(key));
}
return builder.build().toString();
