js 对象拼接为url参数

let params = { key1: 'value1', key2: 'value2' };
let searchParams = new URLSearchParams(params);
let url = 'http://example.com?' + searchParams.toString();
console.log(url); // 输出: http://example.com?key1=value1&key2=value2

function objectToUrlParams(obj) {
    return Object.keys(obj).map(key => `${encodeURIComponent(key)}=${encodeURIComponent(obj[key])}`).join('&');
}

let params = { key1: 'value1', key2: 'value2' };
let url = 'http://example.com?' + objectToUrlParams(params);
console.log(url); // 输出: http://example.com?key1=value1&key2=value2

let valueWithSpecialChars = 'hello world & test';
let encodedValue = encodeURIComponent(valueWithSpecialChars);
console.log(encodedValue); // 输出: hello%20world%20%26%20test

function orderedObjectToUrlParams(obj) {
    let pairs = [];
    for (let key in obj) {
        if (obj.hasOwnProperty(key)) {
            pairs.push(`${encodeURIComponent(key)}=${encodeURIComponent(obj[key])}`);
        }
    }
    return pairs.join('&');
}
