使用requests请求网页时，返回的页面信息有时是乱码，如下代码
headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36' } def get_all(url,key): params = { 'keyword':key, 'enc':'utf-8' } response = requests.get(url=url,params=params,headers=headers) with open('jd.html','w',encoding='utf-8') as f: f.write(response.text) if __name__ == '__main__': key = input('输入搜索内容：') url = 'https://search.jd.com/Search?' get_all(url,key)
返回的部分内容；
<div class="p-name p-name-type-2"> <a target="_blank" title="æå°ä¼ 说çè¢Tæ¤ç·å¤å£é©çæ½®æµçè¢ç·å£«åè¢tæ¤åé¢ä¼é²ä¿®èº«å¤§ç äºåè¢æ½®çéå¹´å¦çtæ¤è¡£æç·è£ 430é»è² M" href="//item.jd.com/51029271063.html" onclick="searchlog(1,51029271063,8,1,'','flagsClk=1077936264')"> <em>æå°ä¼ 说çè¢Tæ¤<font class="skcolor_ljg">ç·</font>å¤å£é©çæ½®æµçè¢ç·å£«åè¢tæ¤åé¢ä¼é²ä¿®èº«å¤§ç äºåè¢æ½®çéå¹´å¦çtæ¤è¡£æ<font class="skcolor_ljg">ç·è£ </font> 430é»è² M</em> <i class="promo-words" id="J_AD_51029271063"></i> </a> </div>
解决方法和思路过程；
代码；
def get_all(url,key): params = { 'keyword':key, 'enc':'utf-8' } response = requests.get(url=url,params=params,headers=headers) # 打印出所请求页面返回的编码方式 print(response.encoding) # response.apparent_encoding是通过内容分析出的编码方式，这里是urf-8 print(response.apparent_encoding) # 转码 content = response.text.encode(response.encoding).decode(response.apparent_encoding) print(content) with open('jd.html','w',encoding='utf-8') as f: f.write(content) if __name__ == '__main__': key = input('输入搜索内容：') url = 'https://search.jd.com/Search?' get_all(url,key)
控制台输出（部分）；

补充，方法二；
response = requests.get(url=url, headers=headers) etrees = etree.HTML(response.content.decode("gb18030"))
done。
