Python使用request包请求网页乱码解决方法
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
使用requests請求網頁時，返回的頁面信息有時是亂碼，如下代碼
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('輸入搜索內容：')url = 'https://search.jd.com/Search?'get_all(url,key)返回的部分內容；
-------------------------------------------------------------------- 注：如果你對python感興趣，我這有個學習Python基地，里面有很多學習資料，感興趣的+Q群：895817687 -------------------------------------------------------------------- <div class="p-name p-name-type-2"><a target="_blank" title="?????°?? èˉ′??-è￠–T??¤?”·?¤??-￡é???‰?????μ???-è￠–?”·?￡????è￠–t??¤???é￠???‘é—2???èo??¤§? ??o”???è￠–????‰?é?’?1′?-|?”?t??¤è?￡????”·è￡430é??è‰2 M" href="//item.jd.com/51029271063.html" οnclick="searchlog(1,51029271063,8,1,'','flagsClk=1077936264')"><em>?????°?? èˉ′??-è￠–T??¤<font class="skcolor_ljg">?”·</font>?¤??-￡é???‰?????μ???-è￠–?”·?￡????è￠–t??¤???é￠???‘é—2???èo??¤§? ??o”???è￠–????‰?é?’?1′?-|?”?t??¤è?￡???<font class="skcolor_ljg">?”·è￡ </font> 430é??è‰2 M</em><i class="promo-words" id="J_AD_51029271063"></i></a></div>解決方法和思路過程；

def get_all(url,key):params = {'keyword':key,'enc':'utf-8'}response = requests.get(url=url,params=params,headers=headers)# 打印出所請求頁面返回的編碼方式print(response.encoding)# response.apparent_encoding是通過內容分析出的編碼方式，這里是urf-8print(response.apparent_encoding)# 轉碼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('輸入搜索內容：')url = 'https://search.jd.com/Search?'get_all(url,key)控制臺輸出（部分）；
