js url传递json

// 假设有一个JSON对象
const data = {
  name: "John",
  age: 30,
  hobbies: ["reading", "gaming"]
};

// 将JSON对象序列化为字符串并进行URL编码
const jsonString = JSON.stringify(data);
const encodedData = encodeURIComponent(jsonString);

// 构建URL
const url = `https://example.com/api?data=${encodedData}`;

console.log(url); // 输出: https://example.com/api?data=%7B%22name%22%3A%22John%22%2C%22age%22%3A30%2C%22hobbies%22%3A%5B%22reading%22%2C%22gaming%22%5D%7D

// 在接收端解码并反序列化
const params = new URLSearchParams(window.location.search);
const receivedData = params.get('data');
const decodedData = decodeURIComponent(receivedData);
const jsonData = JSON.parse(decodedData);

console.log(jsonData); // 输出: { name: 'John', age: 30, hobbies: [ 'reading', 'gaming' ] }
