向url中的添加参数,要求传递对象后解析成参数到url上

例如：传参{name:'张三',age：18}，

function urlFn(obj) {
	let url = 'http://www.alibb.com'
	let keys = Object.keys(obj)
	let values = Object.values(obj)
	url += '?'
	for (let i = 0; i < keys.length; i++) {

		if (i == keys.length - 1) {
			url += `${keys[i]}=${values[i]}`
		} else {
			url += `${keys[i]}=${values[i]}&`
		}

	}
	return url
}

得到http://www.alibb.com?name=张三&age=18

 url 不固定可以采用传参的方式

function urlFn(obj,url) {
	let keys = Object.keys(obj)
	let values = Object.values(obj)
	url += '?'
	for (let i = 0; i < keys.length; i++) {

		if (i == keys.length - 1) {
			url += `${keys[i]}=${values[i]}`
		} else {
			url += `${keys[i]}=${values[i]}&`
		}

	}
	return url
}
let obj = {
    name:'小明',
    age:'18'
}
let url = 'http://www.alibb.com'
console.log(urlFn(obj,url))
//http://www.alibb.com?name=小明&age=18
