百度搜索结果url加密算法 Python源码

百度搜索结果都是加密过的，比如：

lyvba.com --> https://www.baidu.com/link?url=a3f48d30fc293c5e471ef23de092fddc99b897cd745eeca534dc93

以下就是用python实现加密的方法，此方法的缺点是无法加密https的链接，算是比较老的算法，但是仍然可以用(常被seo人士用于shua排名等领域)。

    return 'https://www.baidu.com/link?url=a3f48d30fc293c5e471ef23de092fddc99' + mi

#  输入 lyvba.com  转换 b897cd745eeca534dc93
if __name__ == '__main__':
    t = encode_url("lyvba.com")
    print( "lyvba.com" + " --> " + t)

访问网址即可正常跳转。

另外，如何获取加密之后的真实地址就简单多了，直接http访问加密后的地址，获取返回头部里的301跳转地址就行了。

import requests
url = 'https://www.baidu.com/link?url=a3f48d30fc293c5e471ef23de092fddc99b897cd745eeca534dc93'
r = requests.get(url)
# print(r.text)
print(r.url)
