获取 google api tkk值以及 tk 值计算——纯Py

1. 获取 tkk 值

吾爱破解上有朋友对https://translate.google.cn/网页进行分析来获取tkk值，点这里

下面分享一个 python 版获取 ttk 值的代码：

    def _get_token_key(self):
        if self.token_key is not None:
            return self.token_key

        response = requests.get("https://translate.google.com/")
        tkk_expr = re.search("(tkk:.*?),", response.text)
        if not tkk_expr:
            raise ValueError(
                "Unable to find token seed! Did https://translate.google.com change?"
            )

        tkk_expr = tkk_expr.group(1)
        try:
            # Grab the token directly if already generated by function call
            result = re.search("\d{6}\.[0-9]+", tkk_expr).group(0)
        except AttributeError:
            # Generate the token using algorithm
            timestamp = calendar.timegm(time.gmtime())
            hours = int(math.floor(timestamp / 3600))
            a = re.search("a\\\\x3d(-?\d+);", tkk_expr).group(1)
            b = re.search("b\\\\x3d(-?\d+);", tkk_expr).group(1)

            result = str(hours) + "." + str(int(a) + int(b))

        self.token_key = result
        return result

目前发现可用的 ttk 值有：
422392.71207223
406644.3293161072
431767.4042228602

2. 获取 tk 值

完整版代码如下：

# -*- coding: utf-8 -*-
import calendar
import math
import time
import requests
import re


class Token:

    SALT_1 = "+-a^+6"
    SALT_2 = "+-3^+b+-f"

    def __init__(self):
        self.token_key = None

    def calculate_token(self, text, seed=None):
        if seed is None:
            seed = self._get_token_key()

        [first_seed, second_seed] = seed.split(".")

        try:
            d = bytearray(text.encode('UTF-8'))
        except UnicodeDecodeError:
            # This will probably only occur when d is actually a str containing UTF-8 chars, which means we don't need
            # to encode.
            d = bytearray(text)

        a = int(first_seed)
        for value in d:
            a += value
            a = self._work_token(a, self.SALT_1)
        a = self._work_token(a, self.SALT_2)
        a ^= int(second_seed)
        if 0 > a:
            a = (a & 2147483647) + 2147483648
        a %= 1E6
        a = int(a)
        return str(a) + "." + str(a ^ int(first_seed))

    def _get_token_key(self):
        if self.token_key is not None:
            return self.token_key

        response = requests.get("https://translate.google.com/")
        tkk_expr = re.search("(tkk:.*?),", response.text)
        if not tkk_expr:
            raise ValueError(
                "Unable to find token seed! Did https://translate.google.com change?"
            )

        tkk_expr = tkk_expr.group(1)
        try:
            # Grab the token directly if already generated by function call
            result = re.search("\d{6}\.[0-9]+", tkk_expr).group(0)
        except AttributeError:
            # Generate the token using algorithm
            timestamp = calendar.timegm(time.gmtime())
            hours = int(math.floor(timestamp / 3600))
            a = re.search("a\\\\x3d(-?\d+);", tkk_expr).group(1)
            b = re.search("b\\\\x3d(-?\d+);", tkk_expr).group(1)

            result = str(hours) + "." + str(int(a) + int(b))

        self.token_key = result
        return result

    """ Functions used by the token calculation algorithm """
    def _rshift(self, val, n):
        return val >> n if val >= 0 else (val + 0x100000000) >> n

    def _work_token(self, a, seed):
        for i in range(0, len(seed) - 2, 3):
            char = seed[i + 2]
            d = ord(char[0]) - 87 if char >= "a" else int(char)
            d = self._rshift(a, d) if seed[i + 1] == "+" else a << d
            a = a + d & 4294967295 if seed[i] == "+" else a ^ d
        return a
        

if __name__ == '__main__':
    token=Token()
    text="ruirui ai weiwei"
    print("text:",text)
    print("tk:",token.calculate_token(text))

懂JS的朋友可以参考嵌入JS版python代码：

import execjs

class Py4Js():
    
    def __init__(self):
        self.ctx = execjs.compile("""

        for (var e = [], f = 0, g = 0; g < a.length; g++) {

            e[f++] = m & 63 | 128)
        }
        a = b;
        for (f = 0; f < e.length; f++) a += e[f],
        a = RL(a, $b);
        a = RL(a, Zb);
        a ^= b1 || 0;

        for (var c = 0; c < b.length - 2; c += 3) {
