Python使用request包請求網頁亂碼解決方法

Python之眼發表於2019-08-09
Python網頁

使用requests請求網頁時，返回的頁面資訊有時是亂碼，如下程式碼

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('輸入搜尋內容：')
    url = 'https://search.jd.com/Search?'
    get_all(url,key)

返回的部分內容；

解決方法和思路過程；

程式碼；

def get_all(url,key):
    params = {
        'keyword':key,
        'enc':'utf-8'
    }
    response = requests.get(url=url,params=params,headers=headers)
    # 列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，這裡是urf-8
    print(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('輸入搜尋內容：')
    url = 'https://search.jd.com/Search?'
    get_all(url,key)
