汕尾pvc管粘接胶 取蓝奏云直链教程（附python源码）

浏览器 python环境汕尾pvc管粘接胶

访问我们的网盘分享链接， 浏览器开F12元素 直接看下载按钮的属， 会发现直接包含了下载直链，我们尝试直接request，看看能不能直接获取这个直链

import requests
url = "https://wwt.lanzouu.com/icuiF1o31f8d"
headers={
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36 Edg/121.0.0.0"
    }
response = requests.get(url, headers=headers)
print(response.text)

运行后会发现没有我们刚刚找到的直链，但是发现了另外个链接跟网页中格式是相同的 所以我们就要先从这个链接入手，看看他返回什么， 我们开浏览器的网络调试，发现他确实访问了这个网页 点开response查看响应，发现了下载地址来源于个ajax脚本 我们把这个ajax扔到chatgpt 发现其实是个post请求，将data中包含的几个值post到指定网页，我们在网络调试中也可以看到 —————— 说了这么多程序还不能匹配这个网页，我们先给程序加上正则

import re
iframe_pattern = re.compile(r'<iframe\s+class="ifr2"\s+name="\d+"\s+src="https://www.52pojie.cn/([^"]+)"\s+frameborder="0"\s+scrolling="no"></iframe>')
matches = iframe_pattern.findall(response.text)

这样matches[1]就是我们要的网页了汕尾pvc管粘接胶。 再次request这个网页。

response2 = requests.get(matches[1], headers=headers)
print(response2.text)

运行发现……竟然报错了！ 原来是忘记把域名加上了，这里我们可以直接添加

response2 = requests.get(f"https://wwt.lanzouu.com{matches[1]}, headers=headers)

也可以写个函数正则匹配我们的url的域名汕尾pvc管粘接胶

def re_domain(url): 
    pattern_domain = r"https?://([^/]+)"
    match = re.search(pattern_domain, url)
    if match:
        domain = match.group(1)
        return domain
    else:
        return None

发现确实能取回这个ajax脚本，保温护角专用胶那不就好办了 多试几次发现只有sign是变化的，剩下的几个data都是固定的 所以正则匹配我们需要的sign和下步post的url

pattern = r"'sign'\s*:\s*'([^']+)'"
match = re.search(pattern, response2.text)
pattern2 = r"url\s*:\s*'([^']+)'"
match2 = re.search(pattern2, response2.text)
print(match[0], match2[0])

'sign':'VTMHOVloBjcEDVRrCzsAPFQ_aBTZSPgMwBzFXYwVsW29SYVUkAClSOwViVjdUMQEwVzsFMwRtADQCMVBk' url : '/ajaxm.php?file=163112553'

取出了sign和url就好办了，直接写下个post 注意这里的sign和url都不是str类型，而是Match类型，我们要先用group(1)法取回str （有的人会说为啥不直接post这个固定网页还要进行前面的操作？ 因为sign值是会变化的，只有通过二次访问我们才能知道这个sign值是多少）

data = {
    'action': 'downprocess',
    'signs': '?ctdf',
    'sign': match.group(1),
    'websign': '',
    'websignkey': 'bL27',
    'ves': 1
}
response3 = requests.post(f"https://{re_domain(url)}{match2.group(1)}", headers=headers, data=data)
print(response3.text)

{"zt":1,"dom":"https:\/\/down-load.lanrar.com","url":"?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","inf":0}

取回的text是json格式的，那么我们就要用json解析它

import json
data = json.loads(response3.text)

通过上面的ajax脚本我们会发现他下载链接的拼接式为dom + "/file/" + url

dom = data['dom']
url = data['url']
full_url = dom + "/file/" + url
print(full_url)

印这个url后发现，不管是我们用python request还是浏览器访问这个网页，都显示错误400 查看浏览器的网络调试，原来是访问的时候协议头有个来源 这个挺关键的，我们把它加到post的协议头中

headers2 = {
    "Referer": matches[1],
    "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36 Edg/121.0.0.0"
}
response3 = requests.post(f"https://{re_domain(url)}{match2.group(1)}", headers=headers2, data=data)

重新运行得到新的直链，开发现就能正常下载了 但是我们观察浏览器，发现其实这个直链还进行了次重定向，那么我们也进行次重定向再获取重定向后的网页

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",
"sec-ch-ua": "\"Chromium\";v=\"122\", \"Not(A:Brand\";v=\"24\", \"Microsoft Edge\";v=\"122\"",
"sec-ch-ua-mobile": "?0",
"sec-ch-ua-platform": "\"Windows\"",
"sec-fetch-dest": "document",
"sec-fetch-mode": "navigate",
"sec-fetch-site": "none",
"sec-fetch-user": "?1",
"upgrade-insecure-requests": "1",
"cookie": "down_ip=1"
}
response = requests.get(full_url, headers=headers, allow_redirects=False)
print(response.headers['Location'])

运行后终于找到了终的直链
