## 从响应头获取 buvid3 / b_nut
|
||
|
||
使用 `GET` 或 `HEAD` 方法请求 `https://www.bilibili.com/`, 且请求头中 `User-Agent` 字段不包含 `curl` `python` `awa` 等敏感子字符串, 且相同 `User-Agent` 字段不得短时多次请求. 在响应头中的 `Set-Cookie` 字段中, 即可找到 `buvid3` 和 `b_nut`.
|
||
|
||
若不带任何 Cookie 请求, 则 `b_nut` 为响应生成时刻的 UNIX 秒级时间戳.
|
||
若请求 Cookie 仅带有 `buvid3`, 则 `b_nut` 为 `100`.
|
||
若请求 Cookie 仅带有 `b_nut`, 则与不带任何 Cookie 的响应相同.
|
||
若请求 Cookie 仅带有 `buvid3` 和 `b_nut`, 则响应无 `Set-Cookie` 字段.
|
||
若请求 Cookie 带有其他字段, 无影响.
|
||
|
||
**示例:**
|
||
|
||
```shell
|
||
curl -I "https://www.bilibili.com/" -A "awa"
|
||
```
