url.toJSON()

• 返回: <string>

URL 对象上的 toJSON() 方法返回序列化的网址。 返回值等同于 url.href 和 url.toString() 的值。

当 URL 对象用 JSON.stringify() 序列化时，会自动调用此方法。

const myURLs = [
  new URL('https://www.example.com'),
  new URL('https://test.example.org'),
];
console.log(JSON.stringify(myURLs));
// 打印 ["https://www.example.com/","https://test.example.org/"]

• Returns: <string>

The toJSON() method on the URL object returns the serialized URL. The value returned is equivalent to that of url.href and url.toString().

This method is automatically called when an URL object is serialized with JSON.stringify().

const myURLs = [
  new URL('https://www.example.com'),
  new URL('https://test.example.org'),
];
console.log(JSON.stringify(myURLs));
// Prints ["https://www.example.com/","https://test.example.org/"]
