CKAN数据存储区搜索，无法获取特定字段

Question

我使用以下字段和数据创建了CKAN数据存储

"primary_key" : ["Book ID"],
        "fields" :[
            {"id":"Book ID","type":"number"},
            {"id":"Book Name","type":"text"},
            {"id":"Author","type":"text"},
            {"id":"Publications","type":"text"},
            {"id":"Price","type":"text"},
            {"id":"Discount","type":"text"}

        ],
        "records": [ 
                    {   "Book ID" :"1",
                        "Book Name" :"Book1",
                        "Author" :"Author1",
                        "Publications" :"Pub1",
                        "Price" :"895",
                        "Discount" :"5"
                    },
                    {   "Book ID" :"2",
                        "Book Name" :"Book2",
                        "Author" :"Author2",
                        "Publications" :"Pub2",
                        "Price" :"699",
                        "Discount" :"5"
                    },
                    {   "Book ID" :"3",
                        "Book Name" :"Book3",
                        "Author" :"Author3",
                        "Publications" :"Pub3",
                        "Price" :"500",
                        "Discount" :"10"
}]

我需要获取一些特定字段。 我使用datastore_search，并给出了需要获取的字段。但是显示错误。

我的搜索代码：

{ "resource_id": "740d27f5-790c-43d8-9d5d-23c8aab9303e", 
"fields": [
{ "id": "Book Name"},
{ "id": "Author"}
],
"filters": {"Book Name": "Book1"}
}

Answer 1

“字段”是列表或逗号分隔的字符串，在这里您将字段指定为对象数组。

尝试以下代码：

   {
      "resource_id": "740d27f5-790c-43d8-9d5d-23c8aab9303e", 
      "fields": "Book Name,Author",
      "filters": {"Book Name": "Book1"}
    }
