GET请求参数的字符编码

// 客户端JavaScript代码
const params = {
    name: '张三',
    message: '你好，世界！'
};

const queryString = Object.keys(params)
    .map(key => encodeURIComponent(key) + '=' + encodeURIComponent(params[key]))
    .join('&');

const url = 'https://example.com/api?' + queryString;
fetch(url)
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));
