android - JSON 字符串顺序不对

Question

我希望 JSON 字符串与我输入的顺序相同。这是我的查询。

object.put("name", name);
object.put("email", email);
object.put("query", query);

但在结果字符串中显示为

{"email""m@gmail.com","query":"k","name":"a"}

Answer 1

不能保证 JS 对象中键的顺序。如果您需要特定顺序，请考虑使用单独的键数组来保留顺序。

{
  "order":["name", "email", "query"],
  "data":{
    "email":"m@gmail.com",
    "query":"k",
    "name":"a"
  }
}

来自 JSON 规范 http://www.ietf.org/rfc/rfc4627.txt :

An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.
