'utf-8' codec can't decode byte 0x8a in position 0: invalid start byte

当使用`str(爬取的html字节码,encoding=‘utf-8’)`进行编码转换时，报错`UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0x8a in position 0: invalid start byte`。这个错误通常是因为字节码中包含无法被UTF-8编码解析的字节。根据引用中的错误信息，我们可以看到报错的位置是在字节码的起始字节处。这可能是由于字节码被gzip压缩了，导致解码时出现问题。所以我们需要对接收的字节码进行解压操作。

解决方法是使用`gzip`库对字节码进行解压，然后再进行编码转换。具体操作如下：

from urllib import request
from io import BytesIO
import gzip

class Spider():
    url = 'https://www.douyu.com/'
    
    def __fetch_content(self):
        r = request.urlopen(Spider.url)
        htmls = r.read()
        buff = BytesIO(htmls)
        f = gzip.GzipFile(fileobj=buff)
        htmls = f.read().decode('utf-8')
        print(htmls)
        
    def go(self):
        self.__fetch_content()

spider = Spider()
spider.go()

以上代码首先使用`gzip`库对字节码进行解压，然后再将解压后的字节码进行UTF-8编码解析。这样就可以避免报错`UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0x8a in position 0: invalid start byte`。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
