这个用例测试就有问题的，对象的字段顺序自动排的，stringify怎么可能会全等
function () {var obj = _getParams('https://scriptoj.com/problems?offset=100&limit=10'); var result = JSON.stringify(obj) == JSON.stringify({offset: '100', limit: '10'}); return result; }
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
</head>
<body>
<script>
const _getParams = (url) => {
// 补全代码
const parsedUrl = new URL(url);
const params = {};
try {
parsedUrl.searchParams.forEach((value, key) => params[key] = value);
return params;
} catch(error) {
throw new Error(error);
}
}
</script>
</body>
