【Python3爬虫】破解时光网登录加密参数并实现模拟登录
2024-08-23 06:04:25
一、站点分析
MTime 时光网是一个电影媒体与电商服务平台，而这次做的模拟登录则是依靠其手机端站点，站点地址为：https://m.mtime.cn/#。切换到登录页面，再分别输入账号和错误的密码，点击登录，登录失败，截图如下：
打开开发者工具， 选择“Network”，切换到“XHR”选项，找到一条名为 login.api 的请求，打开后可以发现就是登录所发送的请求，再查看该请求的参数部分，截图如下：
二、参数破解
1.参数分析
经过前面的分析可知有五个参数需要获取，分别是 t、name、password、code 和 codeId，其中 code 和 codeId 目前看来是空的，无须处理，而 name 就是输入的手机号，password 应该是输入的密码加密后的结果，剩下一个 t 还不知道是什么含义。
2.参数获取
在开发者工具中，Ctrl + F 全局搜索“password”，找到如下的 JavaScript 文件：
https://static3.mtime.cn/html5/20200116143308/js/views/member/signin.js
打开该文件后搜索“password”，首先是获取 name 属性为“password”的输入框，在下文中还发现了 vcode 和 vcodeId，这两个就是后面请求所需的 code 和 vcode 参数的值，截图如下：
继续搜索“password”，可以找到一个 getPassword() 方法，用于获取输入的密码内容，截图如下：
接着搜索“password”，找到如下内容：
这就是登录请求时的参数部分，其中密码 password 是将输入的密码进行加密后的结果，使用的是 f.desEcbPkcs7 方法，那这个方法具体是什么呢？
3.加密方法
在上面的 JS 文件中的 217 行打上断点，然后刷新页面并重新登录，页面会进入 debugger 模式，然后选中 desEcbPkcs7 部分，点击后跳转到 app.all.min.js 中的如下代码部分：
这个 af 函数就是加密方法了，其中用到了一个变量 CryptoJS，要获取这个变量的定义，就在上面代码中的1033行打上断点，再重新登录一遍，定位到 CryptoJS 的定义部分，截图如下：
对于变量 CryptoJS 的定义包含在 libs.all.min.js 中，但这个文件中的代码量比较大，若全部复制下来使用会不方便，而我们也只需要得到对变量 CryptoJS 进行定义的代码就够了，所以建议先把该 JS 文件保存到本地，再用编辑器打开，就能很快地得到我们所需要的代码了，即使如此还是有一千四百多行（汗~）。

得到了加密代码之后，我们只需要使用 execjs 进行编译和调用就可以了，使用方法可以参考上一篇博客。
三、模拟登录
通过前面的步骤，我们已经能够得到登录所需要的参数了，编写好加密方法之后，可以使用 Postman 进行测试，下面是用 Postman 进行登录的 POST 请求的响应结果：
从图中可以看到，返回的是一个 JSON 文件，其中包含了登录请求是否成功、登录的结果信息和用户信息等内容。 下面就是使用 Python 编写的模拟登录时光网的代码：
"""
Version: Python3.7
Author: OniOn
Site: http://www.cnblogs.com/TM0831/
Time: 2020/7/5 14:19
"""
import execjs
import requests class MTimeSpider:
def __init__(self, username, password):
self.username = username
self.password = password def encrypted(self):
"""
use JavaScript to encrypt the password
:return:
"""
with open("encrypt.js", "r", encoding="utf-8") as f:
ctx = execjs.compile(f.read())
self.password = ctx.call("encrypt", self.password) def request(self):
"""
send request and get the response
:return:
"""
self.encrypted()
login_api = "https://m.mtime.cn/Service/callback-comm.mi/user/login.api"
data = {
"t": "",
"name": self.username,
"password": self.password,
"code": "",
"codeId": ""
}
res = requests.post(url=login_api, data=data)
status, msg = res.json()["data"]["status"], res.json()["data"]["msg"]
# print(status, msg)
if status == 1:
name = res.json()["data"]["user"]["nickname"]
print("用户： {} 登录成功！".format(name))
else:
print("登录失败！{}".format(msg)) if __name__ == '__main__':
print("请输入账号：")
usr = input()
print("请输入密码：")
pwd = input()
spider = MTimeSpider(usr, pwd)
spider.request()
