如何使用urllib Python3库转换以下代码？

import requests

url = "https://api.example.com/data"
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
}

response = requests.get(url, headers=headers)
data = response.json()
print(data)

import urllib.request
import json

url = "https://api.example.com/data"
headers = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3"
}

req = urllib.request.Request(url, headers=headers)
with urllib.request.urlopen(req) as response:
    data = json.loads(response.read().decode())
    print(data)
