布尔值是有效的JSON吗 [英] Are booleans valid JSON

问题描述

为什么有些JSON验证器将布尔值标记为无效JSON，而另一些则将其标记为有效?也就是说，只有true或false值(无对象).

Why do some JSON validators flag a boolean value as invalid JSON, and others as valid? That is, just true or false values (no object).

推荐答案

您链接到的验证器根据true存在的JSON字符串验证为无效. org/html/rfc4627"rel =" noreferrer> RFC 4627 ，它指示JSON字符串的根是数组或对象:

The validator you link to validates the JSON string existing of a mere true as invalid according to RFC 4627, which dictates that the root of a JSON string is to be an array or object:

JSON文本是序列化的对象或数组.

A JSON text is a serialized object or array.

 JSON-text = object / array

根据该RFC ，未包装的值(例如true或"foo"或42)不是JSON .

An unwrapped value such as true or "foo" or 42 is not JSON according to that RFC.

可以验证的其他RFC RFC 7159 认为以上示例有效，因为它不会将JSON文本限制为对象或数组，但还允许 values :

The other RFC it can validate against, RFC 7159, deems the above examples valid as it does not constrain a JSON text to objects or arrays, but also allows values:

JSON值必须是对象，数组，数字或字符串，或者是以下之一 以下三个文字名称:

A JSON value MUST be an object, array, number, or string, or one of the following three literal names:

 false null true

由于前者(RFC 4627)已被后者(RFC 7159)淘汰，因此true 是有效的JSON字符串.

And because the former (RFC 4627) is obsoleted by the latter (RFC 7159), true is a valid JSON string.
