从 Web API 返回 JSON 作为响应

Question

我正在尝试查询 SQL 服务器并尝试以 JSON 格式返回响应。我能够得到像

这样的 JSON 响应

[
  {"R_ID":"368203","ROOM":"K2"}, 
  {"R_ID":"368203","ROOM":"K2"}
]

但我希望将响应包装在数据中，例如

{
  "data": [
    {"R_ID":"368203","ROOM":"K2"}, 
    {"R_ID":"368203","ROOM":"K2"}
   ]
}

所以现在我改变了我的模型类

public class DatabaseResult
{
  public int r_id { get; set; }
  public string room { get; set; }
}

public class RootObject
{
  public List<DatabaseResult> data { get; set; }
}

我不确定如何更改控制器以获得预期的响应

connection.Open();
List<DatabaseResult> records = new List<DatabaseResult>();
using (var reader = command.ExecuteReader())
{
  while (reader.Read())
  {
    var row = new DatabaseResult
    {
      request_id = (int)reader["request_id"],
      room = (string)reader["room"],
    };
    records.Add(row);
  }
  return Ok(records);
}

Answer 1

您可以将records 包装在一个匿名对象中

 return Ok( new {data = records} );

Answer 2

您需要在后端创建相同的模型，然后像这样填充，

RootObject result = new RootObject();


 while (reader.Read())
 {
   var row = new DatabaseResult
   {
      request_id = (int)reader["request_id"],
      room = (string)reader["room"],
   };
   records.Add(row);
 }
 result.data = records;

然后返回 result.
