Java写的:

String html_url = "https://www.lanzous.com/i6cSsepn2aj";
        Connection html_head = Jsoup.connect(html_url);
            html_head.header("Accept", "text/html, application/xhtml+xml, */*"); 
            html_head.header("Content-Type", "application/x-www-form-urlencoded");
            html_head.header("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.3");
            html_head.header("referer", html_url);

            String html2_url = "https://www.lanzous.com"+(html_head.get().select("iframe").first().attr("src"));

            Elements html2 = Jsoup.connect(html2_url).get().getElementsByTag("script"); 

            String[] data = html2.get(1).data().split("data");

            String action = "downprocess"; //参数一
            String sign = data[2].substring(data[2].indexOf("sign':")+6, data[2].lastIndexOf(",'ves':1")); //取得参数二



            String post_url = "https://www.lanzous.com/ajaxm.php";

            Connection post_url_head = Jsoup.connect(post_url);
            post_url_head.header("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36 OPR/28.0.1750.51");
            post_url_head.header("Accept-Encoding","gzip, deflate, lzma, sdch");
            post_url_head.header("Accept-Language","zh-CN,zh;q=0.8");
            post_url_head.header("Accept","text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");


            post_url_head.data("action", action);
            post_url_head.data("sign", sign);
            post_url_head.data("ves", "1");


            System.out.println(post_url_head.post());

python 写的

#coding=utf-8
from bs4 import BeautifulSoup
import requests
import re
import json

#蓝奏云分享文件链接地址
url = 'https://wwa.lanzous.com/i6cSsepn2aj'

#header头,注意那个referer必须要与上面文件分享地址url相同
headers = {
    'User-Agent':'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.121 Safari/537.3',
    'referer': url
}

# 获取分享页面html文件
res = requests.get(url,headers=headers)

# 引入BeautifulSoup库对html进行处理,获取iframe中的出现的js文件
soup = BeautifulSoup(res.text,'html.parser')
url2 = 'https://www.lanzous.com/'+soup.find('iframe')['src']
res2 = requests.get(url2,headers=headers)

# 正则提取请求三个参数
sign = re.findall("\'sign\':(\'.*?\')",res2.text)
# 请求下载地址
url3 = 'https://www.lanzous.com/ajaxm.php'
data = {
    'action':'downprocess',
    'sign':sign,
    'ves':'1'
}
res3 = requests.post(url3,headers=headers,data=data)
res3 = json.loads(res3.content)

# 请求最终重定向地址
url4 = res3['dom']+'/file/'+res3['url']

headers2 = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0',
    'Accept-Language': 'zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2',
}
res4 = requests.head(url4, headers=headers2)
print(res4.headers['Location'])

Java输出 的 :

<html>
 <head></head>
 <body>
  {"zt":1,"dom":"https:\/\/vip.d0.baidupan.com","url":"?UzVaZFprBTQACVNrBzJUOFtkBDxTfgJlA3dVPF10B3RVNlZkWnQEflJ+AzwFIVN0UW1TP15tAGcKUgZpBj5SblNhWjtaMwViAG5TMAdiVGxbJwRnU38CPQMzVWpdMAcwVWJWOFo3BHZSdAMlBWxTYFE7U2ReMQAtCj0GNwZ1UmJTa1oiWjMFNQBmUzYHYFRmWzAENVM7AmMDYFVgXTkHMlVtVjZaNARnUjIDbAU0U2NRPFM3XjgAYwo8BmQGY1IwUzBabFopBSsAP1N1B3VUIFtyBGRTfgJpA2BVbl0yBz9VZlY0WjIEY1IiAyEFOFM\/UW5TMF48ADMKPQYwBmpSY1N9WiNaIQU3ADpTcgduVGRbNAQ4UzkCMwM8VWtdMAc1VWJWJ1pyBCBScwNoBWBTZ1EyU2NeMQA0CjwGNwZtUmNTdVp4Wm4FIQBrUzQHa1RmWy8EM1M5AjMDKlVgXTMHKFVgVjA=","inf":0}
 </body>
</html>

但是这个拼起来去访问却显示错误 而且java输出的这个http:\/\/ 为啥是这样的 url里面也有一些,我以为是这个问题,替换回/后也还是错误

 

python写的不会 py输出的 res3那边
