'utf-8'报错的问题 不知道错在哪

Question

产生这样的报错'utf-8' codec can't decode byte 0x8b in position 1: invalid start byte
我代码：
from urllib import request
url = "http://odds.500.com/fenxi/yazhi-749525.shtml"
headers = {

"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0"
}

req = request.Request(url)
resp = request.urlopen(req)
a = resp.read()
print(a.decode('utf-8'))### 问题描述

问题出现的环境背景及自己尝试过哪些方法

网页经过了gzip压缩，需要解压：

from urllib import request
import gzip

url = "http://odds.500.com/fenxi/yazhi-749525.shtml"
headers = {

"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:61.0) Gecko/20100101 Firefox/61.0"
}
req = request.Request(url)
resp = request.urlopen(req)
f = gzip.decompress(resp.read())
print(f.decode('gbk'))

更推荐直接使用requests库：

import requests
url = "http://odds.500.com/fenxi/yazhi-749525.shtml"
content = requests.get(url).content

print(content.decode('gbk'))
