#这些是地理信息

x-app-encrypt-text  
#这个明显是加密信息

#请求参数中pw很明显做了加密

#首先先不管请求头直接搞请求参数加密
#为什么呢不搞请求头呢,因为请求头未必有用

这个全经验吧,同学们自己多多专研这个很难教

#python转一下
from Crypto.Cipher import AES


class Aes_ECB(object):
    def __init__(self):
        self.key = 'gSPs4aHZL1ocan1w'  #秘钥
        self.MODE = AES.MODE_ECB
        self.BS = AES.block_size
        self.pad = lambda s: s + (self.BS - len(s) % self.BS) * chr(self.BS - len(s) % self.BS)
        self.unpad = lambda s: s[0:-ord(s[-1])]

    # str不是16的倍数那就补足为16的倍数
    def add_to_16(value):
        while len(value) % 16 != 0:
            value += '\0'
        return str.encode(value)  # 返回bytes

    def AES_encrypt(self, text):
        aes = AES.new(Aes_ECB.add_to_16(self.key), self.MODE)  # 初始化加密器
        encrypted_text = aes.encrypt(Aes_ECB.add_to_16(self.pad(text))).hex()
        # 执行加密并转码返回bytes
        return encrypted_text

#找java层方法都一样,日积月累关键字查找,你会发现x-app-encrypt-text在so文件中
