mark一下平時的練習(xí)

練習(xí)網(wǎng)站:古詩文網(wǎng)站

思路:將圖片驗證碼下載到本地，手動輸入驗證碼，進(jìn)行登錄識別。

import requests
from lxml import etree

headers={
'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36'
}

def get_session():
    session=requests.session()
    return session

def get_value(session):
    url='https://so.gushiwen.org/user/login.aspx?from=http://so.gushiwen.org/user/collect.aspx'
    response=session.get(url,headers=headers)
    html=etree.HTML(response.text)
    VIEWSTATE=html.xpath('//*[@id="__VIEWSTATE"]/@value')[0]
    print(VIEWSTATE)
    return VIEWSTATE

def get_img(session):
    url='https://so.gushiwen.org/RandCode.ashx'
    response=session.get(url,headers=headers)
    with open ('code.png','wb')as f :
        f.write(response.content)


def login(VIEWSTATE,code,session):
    url = 'https://so.gushiwen.org/user/login.aspx?from=http%3a%2f%2fso.gushiwen.org%2fuser%2fcollect.aspx'
    data={
        '__VIEWSTATE':VIEWSTATE ,
        '__VIEWSTATEGENERATOR':'C93BE1AE',
        'from':'http://so.gushiwen.org/user/collect.aspx',
        'email': ##,
        'pwd': ##,
        'code': code,
        'denglu': '登錄'
    }
    response=session.post(url,headers=headers,data=data)
    if response.url=='https://so.gushiwen.org/user/collect.aspx':
        print('登入成功')
    else:
        print('登入失敗')

if __name__ == '__main__':
    session=get_session()
    VIEWSTATE=get_value(session)
    get_img(session)
    code=input('請輸入驗證碼:')
    login(VIEWSTATE,code,session)

ps:本人是小白一枚，內(nèi)容可能不太專業(yè)，有不嚴(yán)謹(jǐn)?shù)牡胤秸堉更c，謝謝呢~
