创建一个sitemap类，返回带有两个参数的URL

import urllib.parse

class Sitemap:
    def __init__(self, base_url):
        self.base_url = base_url
        self.urls = []

    def add_url(self, path, params):
        url = urllib.parse.urljoin(self.base_url, path)
        url_with_params = url + '?' + urllib.parse.urlencode(params)
        self.urls.append(url_with_params)

    def generate_sitemap(self):
        sitemap = '<?xml version="1.0" encoding="UTF-8"?>\n'
        sitemap += '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">\n'
        for url in self.urls:
            sitemap += '  <url>\n'
            sitemap += f'    <loc>{url}</loc>\n'
            sitemap += '  </url>\n'
        sitemap += '</urlset>'
        return sitemap

# 示例用法
sitemap = Sitemap('https://www.example.com')
sitemap.add_url('/page1', {'param1': 'value1', 'param2': 'value2'})
sitemap.add_url('/page2', {'param1': 'value3', 'param2': 'value4'})
sitemap_xml = sitemap.generate_sitemap()
print(sitemap_xml)
