批改网脚本

前天熬了个大夜，下午一点才起，一听到舍友说又要写那个恶心的批改网，气得我直接写了个脚本自动把所有未完成的作文秒杀，话不多说直接开始分析。

一.登陆前的cookies处理

清空网站的所有本地存储，会话存储和cookies，并刷新

可以看到多出了两个cookies，在抓包的地方搜索set-cookie

可以发现这两个cookies是服务器返回的

二.登录请求发送

输入账号密码，点击登录，开始抓包

我们很快就发现了登录验证的请求，这个password被加密了

点击发起程序想看看调用堆栈，结果。。。

居然看不了，只能查看发起请求的程序链子

搜索几个关键字，很快就能发现加密函数

把加密函数搬到本地的js并封装，以便我们后续操作


const JSEncrypt = require('jsencrypt');
 
function encrypt(str) {
    var encrypt = new JSEncrypt();
    encrypt.setPublicKey('MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCYlII16dSwQErDgjIl8BzU4NEL2IzvyWiLNxie3mkpw6eseF/iUVb3bisAFH+lzgnrv/mBOKUMkbqtW2+8en/6r0hj6ctvGT+UOtg4P5LF/jxkbE+cA2fVJK2RaBzeEEbrKOvauVnGkEOvPVl1/NK4NgeN6aSPIK9ECfXcjlEOHwIDAQAB');
    var encrypted = encrypt.encrypt(str);
 
    return encrypted;
}
 
function main123(password){
    return encrypt(password)
}

根据前面的分析逻辑，直接对着验证的链接发请求


headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7',

    'Sec-Fetch-User': '?1',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36 Edg/125.0.0.0',
    'sec-ch-ua': '"Microsoft Edge";v="125", "Chromium";v="125", "Not.A/Brand";v="24"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}
 
response = requests.get('https://www.pigai.org/', headers=headers)
 
PHPSESSID = response.cookies['PHPSESSID']
 
old=response.cookies['old']
 
cookies ={
    'PHPSESSID': PHPSESSID,
    'old': old,
}
 
headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7',
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'Cache-Control': 'no-cache',
    'Connection': 'keep-alive',
    'Content-Type': 'application/x-www-form-urlencoded',
    # 'Cookie': 'old=2012; PHPSESSID=8oj8mlkeavc583i7l2kutgen77',
    'Origin': 'https://www.pigai.org',
    'Pragma': 'no-cache',
    'Referer': 'https://www.pigai.org/',
    'Sec-Fetch-Dest': 'document',
    'Sec-Fetch-Mode': 'navigate',
    'Sec-Fetch-Site': 'same-origin',
    'Sec-Fetch-User': '?1',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36 Edg/125.0.0.0',
    'sec-ch-ua': '"Microsoft Edge";v="125", "Chromium";v="125", "Not.A/Brand";v="24"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}
 
params = {
    'a': 'login',
}
 
data = {
    'username': username,
    'password': '',
    'checkhash': '',
    'password_encrypt': execjs.compile(open('密码加密.js', 'r', encoding='gbk').read()).call('main123', password),
}
 
response = requests.post('https://www.pigai.org/index.php', params=params, cookies=cookies, headers=headers, data=data,allow_redirects=False)

这样我们就算是登陆进去了，可以发现已上代码最后一句话

response = requests.post('https://www.pigai.org/index.php', params=params, cookies=cookies, headers=headers, data=data,allow_redirects=False)

这里我将allow_redirects=False，这是禁止重定向操作，但是为什么要这么做呢？

点击我们刚刚验证的请求，再点击cookies

服务器给我们返回了很多cookies，这些cookies是服务器识别我们身份的标识，所以我们要将其保存下来

但是若我没有禁止重定向操作，最后请求中获取的cookie如下

这是怎么回事呢？点击预览看看

原来是我们验证通过后，服务器会直接给我们重定向到登陆的主界面，若我们不禁止重定向，就无法抓取到能验证我们身份的cookies

三.百度统计第三方cookies处理

点击存储查看一下存在我们本地的cookies

上面那三个cookies其实是批改网引入了百度统计的第三方cookies，百度统计是用来检测访客信息和访客行为的第三方网站，我们直接查看百度统计官方提供的文档

这个Hm_lpvt_和Hm_lvt_我们直接全部设置成当前时间的时间戳就好（意思就是伪装成我们是第一次登录）

这个HMACCOUNT_BFESS是由百度统计接口分配的一个访客id，我们只需要在网站存储中找到一个类似这样的js文件

查看一下服务器响应

也是直接给我们分配了一个访客id，这里应为返回的是js代码的形式，所以要用到正则表达式将这个字段提取，提取过程如下


headers = {
    'Accept': '*/*',
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'Cache-Control': 'no-cache',
    'Connection': 'keep-alive',
    # 'Cookie': 'HMACCOUNT_BFESS=7C04F9FF37E951F6',
    'Pragma': 'no-cache',
    'Referer': 'https://www.pigai.org/',
    'Sec-Fetch-Dest': 'script',
    'Sec-Fetch-Mode': 'no-cors',
    'Sec-Fetch-Site': 'cross-site',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36 Edg/125.0.0.0',
    'sec-ch-ua': '"Microsoft Edge";v="125", "Chromium";v="125", "Not.A/Brand";v="24"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}
 
response = requests.get('https://hm.baidu.com/hm.js?3f46f9c09663bf0ac2abdeeb95c7e516', headers=headers)
 
match = re.search(r"hca:'([0-9A-Fa-f]+)'", response.text)
 
BFESS=match.group(1)

四.批量获取未完成的作文题目

然后，我们点击未完成

抓到了数据包，这里应该会返回我没写完作文的所有信息，但是因为我的作文全部用这个脚本秒了，所以啥都没看到，这里我是用xpath的方法批量提取我没完成作文的所有作文编号，并存在一个列表中


cookies ={
    'PHPSESSID': PHPSESSID,
    'old': old,
    '_JUKU_USER':response.cookies['_JUKU_USER'],
    'isPrize': response.cookies['isPrize'],
    'Hm_lpvt_3f46f9c09663bf0ac2abdeeb95c7e516':str(int(time.time()*1000)),
    'Hm_lvt_3f46f9c09663bf0ac2abdeeb95c7e516':str(int(time.time()*1000)),
    'HMACCOUNT_BFESS':BFESS,
    'JK_GCNT':'0'
}
 
headers = {
    'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7',
    'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
    'Cache-Control': 'no-cache',
    'Connection': 'keep-alive',
    # 'Cookie': 'old=2012; PHPSESSID=eqnfap3mhnh5i894d1e0dorr44; _JUKU_USER=%7B%22i%22%3A%2230209707%22%2C%22u%22%3A%22N633f8e15a0a8a%22%2C%22u2%22%3A%22%5Cu5434%5Cu6bd3%5Cu535a%22%2C%22k%22%3A%22432d6aaf111ccba5cddcce2f653223b1%22%2C%22img%22%3A%22%22%2C%22ts%22%3A2%2C%22s%22%3A%22%5Cu56db%5Cu5ddd%5Cu5927%5Cu5b66%22%2C%22iv%22%3A0%2C%22st%22%3A%220%22%2C%22no%22%3A%222022141530099%22%2C%22cl%22%3A%22105%22%2C%22it%22%3A%221%22%7D; isPrize=0; JK_GCNT=0; Hm_lvt_3f46f9c09663bf0ac2abdeeb95c7e516=1718356284; Hm_lpvt_3f46f9c09663bf0ac2abdeeb95c7e516=1718356284',
    'Pragma': 'no-cache',
    'Referer': 'https://www.pigai.org/index.php?c=write&f2=login',
    'Sec-Fetch-Dest': 'document',
    'Sec-Fetch-Mode': 'navigate',
    'Sec-Fetch-Site': 'same-origin',
    'Sec-Fetch-User': '?1',
    'Upgrade-Insecure-Requests': '1',
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36 Edg/125.0.0.0',
    'sec-ch-ua': '"Microsoft Edge";v="125", "Chromium";v="125", "Not.A/Brand";v="24"',
    'sec-ch-ua-mobile': '?0',
    'sec-ch-ua-platform': '"Windows"',
}
 
params = {
    'c': 'write',
    'a': 'waitComplete',
    'bf': '4',
}
 
response = requests.get('https://www.pigai.org/index.php', params=params, cookies=cookies, headers=headers)
 
tree =etree.HTML(response.text)
 
paragraphs = tree.xpath('//*[@id="essayList"]//ul')
 
sum=0
 
essayLisy=[]
 
for ul in paragraphs:
    if(sum==0):
        sum+=1
 
        continue
 
    essayLisy.append(ul.xpath('.//li[1]/text()')[0])
 
    sum+=1

接着我们带着我们获取的作文编号就能直接请求到写作文的详情页

这里得注意，请求后服务器给我们返回了一个_fromcode的cookies，要注意保存

直接用xpath获取作文题目


for rid in essayLisy:
    headers = {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.7',

        'Sec-Fetch-User': '?1',
        'Upgrade-Insecure-Requests': '1',

        'sec-ch-ua': '"Microsoft Edge";v="125", "Chromium";v="125", "Not.A/Brand";v="24"',
        'sec-ch-ua-mobile': '?0',
        'sec-ch-ua-platform': '"Windows"',
    }
 
    params = {
        'c': 'v2',
        'a': 'write',
        'rid': rid,
    }
 
    response = requests.get('https://www.pigai.org/index.php', params=params, cookies=cookies, headers=headers)
 
    cookies.update({'_fromCode': response.cookies['_fromCode']})
 
    tree = etree.HTML(response.text)
 
    title = tree.xpath('string(//*[@id="request_y"])')

五.调用文言一心api

大公司就是好啊，模型的接口直接给我们随便用

打开百度智能云官网，搜索千帆大模型，创建应用

阅读官方提供的API文档

这里有个接口调试平台，非常的好用

查看我写的调用代码


def main(title):
    url = "https://aip.baidubce.com/rpc/2.0/ai_custom/v1/wenxinworkshop/chat/ernie-3.5-8k-0205?access_token=" + get_access_token()
 
    payload = json.dumps({
        "messages": [
 
            {
                "role": "user",
                "content": title
            }
 
        ],
        "temperature": 0.8,
        "top_p": 0.8,
        "penalty_score": 1,
        "disable_search": False,
        "enable_citation": False,
        "response_format": "text"
    })
    headers = {
        'Content-Type': 'application/json'
    }
 
    response = requests.request("POST", url, headers=headers, data=payload)
 
    return response.json().get('result')
def get_access_token():
    """
    使用 AK，SK 生成鉴权签名（Access Token）
    :return: access_token，或是None(如果错误)
    """
    url = "https://aip.baidubce.com/oauth/2.0/token"
    params = {"grant_type": "client_credentials", "client_id": API_KEY, "client_secret": SECRET_KEY}
    return str(requests.post(url, params=params).json().get("access_token"))

直接调用main函数，并传入作文题目，就能返回对应的文章了

六.上传文章

直接对着这个链接发请求就行了，非常简单，作文仅是经过了简单的url编码


essay=main(title)
 
    headers = {
        'Accept': '*/*',
        'Accept-Language': 'zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6',
        'Cache-Control': 'no-cache',
        'Connection': 'keep-alive',
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
        # 'Cookie': 'old=2012; PHPSESSID=javkrsajhm585dur0nt1a6llf1; _JUKU_USER=%7B%22i%22%3A%2230209707%22%2C%22u%22%3A%22N633f8e15a0a8a%22%2C%22u2%22%3A%22%5Cu5434%5Cu6bd3%5Cu535a%22%2C%22k%22%3A%22432d6aaf111ccba5cddcce2f653223b1%22%2C%22img%22%3A%22%22%2C%22ts%22%3A2%2C%22s%22%3A%22%5Cu56db%5Cu5ddd%5Cu5927%5Cu5b66%22%2C%22iv%22%3A0%2C%22st%22%3A%220%22%2C%22no%22%3A%222022141530099%22%2C%22cl%22%3A%22105%22%2C%22it%22%3A%221%22%7D; isPrize=0; JK_GCNT=0; Hm_lvt_3f46f9c09663bf0ac2abdeeb95c7e516=1718385312; _fromCode=692374; Hm_lpvt_3f46f9c09663bf0ac2abdeeb95c7e516=1718385738',

        'sec-ch-ua-mobile': '?0',
        'sec-ch-ua-platform': '"Windows"',
    }
 
    params = {
        'c': 'ajax',
        'a': 'postSave',
    }
 
    data = {
        'utContent': quote(essay),
        'utTitle': quote('第'+rid+'号 '),
        'bzold': '',
        'bz': '',

        'utype': '',
        'gao': '1',
        'uncheck': '',
        'tiku_id': '0',
        'engine': '',
        'fromCode': cookies['_fromCode'],
        'autoDel': '',
        'stu_class': '',
    }
 
    response = requests.post('https://www.pigai.org/index.php', params=params, cookies=cookies, headers=headers,
                             data=data)
 
    print(response.text)

至此，整个脚本编写的思路就都搞定啦，妈妈再也不用担心我写不完作文了
