有道翻译能够随意输入内容并进行翻译
```python
import requests
import time
import random
from hashlib import md5

# 获取salt sign ts
def get_salt_sign_ts(word):
    # ts
    ts = str(int(time.time() * 1000))
    # salt
    salt = ts + str(random.randint(0, 9))
    # sign

    s = md5()
    s.update(string.encode())
    sign = s.hexdigest()
