解决思路1、
循环暴力寻找编码,但是不如思路3
复制代码
def parse(self, response):
print(response.text[:100])
body = response.body#直接是bytes,response.text是str
encodings = ['utf-8', 'gbk', 'gb2312', 'iso-8859-1', 'latin1']#实际可用response.encoding获得
for encoding in encodings:
try:
print(body.decode(encoding)[:100])#decode必须是bytes
except Exception as e:
print('decode {0}, error: {1}\n'.format(encoding, e))
pass
复制代码
解决思路2、
download minddlewares中有个process_response方法,修改它的encoding即可需要自己组装一个修改了charset的页面response,利用HtmlResponse可以完美解决,实现中文乱码的解决,当然你要在setting.py中启用该download middleware
复制代码
from scrapy.http import HtmlResponse
def process_response(self,request, response, spider):
# 修改页面编码
if response.encoding == 'cp1252':
response = HtmlResponse(url=response.url, body=response.body, encoding='utf-8')
return response
复制代码
解决思路3、
scrapy爬取编码为gb2312的网页时出现中文乱码
python3用库chardet查看编码方式;先用encode编码成bytes,再用decode编码成str
复制代码
import chardet
txt_b=response.xpath('//title').extract()[0].encode(response.encoding)#对找到的具体内容用encode编码成bytes
print(chardet.detect(txt_b))
txt_str= txt_b.decode(response.encoding,errors='ignore')#对bytes内容用decode解码成str
print(txt_str)
