如何解析url

bs_url = "aHR0cHM6Ly9hY2NvdW50LnhpYW9taS5jb20v"
url = base64.b64decode(bs_url).decode()
print(url)
# 通过对参数的分析发现 ，_sign user hash 参数为加密参数
header = {
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/105.0.0.0 Safari/537.36"
}
resp = requests.get(url=url, headers=header)
# print(resp.history[1])
location_url = resp.history[1].headers["Location"]
print(location_url)
urlparse = urllib.parse.urlparse(location_url)
print(urlparse)
query_dict = urllib.parse.parse_qs(urlparse.query)
print(query_dict)

结果：
