BeautifulSoup4 中文乱码

没有评论

BeautifulSoup4解析页面的时候发现有一部分内容是乱码，刚开始还以为是pycharm的问题，后来发现可能问题不是出在pycharm上，因为普通的print打印的中文是没有问题的。测试代码如下：

def proxy_get(url):
    if is_use_proxy:
        socks.set_default_proxy(socks.SOCKS5, PROXY_HOST, PROXY_PORT)
        socket.socket = socks.socksocket
    req = requests.get(url, headers=HEADERS)
    return req.text


def get_sub_pages_test(url):
    '''
    http://www.meitulu.cn/t/shishen/
    :param url:
    :return:
    '''
    bs = BeautifulSoup(proxy_get(url), "html.parser")
    boxes = bs.find('div', class_='boxs')
    lis = boxes.find_all('li')
    log_text('PAGE', '开始分析页面链接', is_begin=True)
    for l in lis:
        p = l.find('p', class_='p_title')
        print( p.text)

}

proxies = {
    #'socks5': '127.0.0.1:8889'
    'http':'socks5://127.0.0.1:8889',
    'https':'socks5://127.0.0.1:8889'
}
url = 'http://nkm3s8.xyz/'
try:
    print('Proxy:')
    res = requests.get(url, headers=headers, proxies=proxies, timeout=10)
    print(res)
except Exception as e:
    print(e)

try:
    print('No Proxy:')
    res = requests.get(url, headers=headers, timeout=10)
    print(res)
