`bili_ticket` 目前没发现多少风控价值，但是暂且在这里提供一份示例。
|
||
|
||
由 [@aynuarance](https://github.com/aynuarance) 于 [#903](https://github.com/SocialSisterYi/bilibili-API-collect/issues/903) 提供的思路，根据时间戳使用 `hmac_sha256` 算法计算 `hexsign`。
|
||
|
||
|
||
是 [JWT 令牌](https://jwt.io/)，有效时长为 259260 秒，即 3 天。
|
||
例如 `eyJhbGciOiJIUzI1NiIsImtpZCI6InMwMyIsInR5cCI6IkpXVCJ9.eyJleHAiOjE3MDI3NDI3NDYsImlhdCI6MTcwMjQ4MzQ4NiwicGx0IjotMX0.xQgtTAc41NA1gzvd9yKUPgucUy_DKcQj6OG1vj8V7ZA`
|
||
|
||
```json
|
||
{
|
||
"alg": "HS256",
|
||
"kid": "s03",
|
||
"typ": "JWT"
|
||
}
|
||
```
|

|
||
# Python 示例
|
||
|
||
```python
|
||
import hmac
|
||
import hashlib
|

import requests
|

import time

def hmac_sha256(key, message):
|

"""
|
||
使用HMAC-SHA256算法对给定的消息进行加密
|
||
:param key: 密钥
|
||
:param message: 要加密的消息
|
||
:return: 加密后的哈希值
|
||
"""
|
||
# 将密钥和消息转换为字节串
|
||
key = key.encode('utf-8')
|
||
message = message.encode('utf-8')
|
||
|
||
# 创建HMAC对象，使用SHA256哈希算法
|
||
hmac_obj = hmac.new(key, message, hashlib.sha256)
|
||
|
||
# 计算哈希值
|
||
hash_value = hmac_obj.digest()
|
||
|
||
# 将哈希值转换为十六进制字符串
|

hash_hex = hash_value.hex()
|

return hash_hex
