UUID (_uuid mentioned above) generation algorithm

See Rust Playground

BUVID Fp (buvid_fp mentioned above) generation algorithm

Tip

Using your own browser's fingerprintjs2 info and related buvid_fp will be the best choice for your crawler.

See Rust Playground

A good way to obtain a buvid_fp

Copy these codes into your browser console:

还有办法能获取用户投稿嘛？我自己测试了好几遍都不行，接口是：/x/space/wbi/arc/search

和本 issue 不相关, 去 #868, 贴上你的代码要不然谁知道发生了什么

[Allenyep]

buvid_fp 影响接口是否返回-352，需要解这个值

[Allenyep]

DIGHT_MAP 考虑把10去掉？

[cxw620]

DIGHT_MAP 考虑把10去掉？

Math.ceil(Math.random() * 16) 取值 0..=16, 就是有 "10" 的, 虽然看起来很像 0-9,a-f.

反而应该去掉 0 因为 Math.random() === 0 太罕见了概率无限接近 0

[cxw620]

buvid_fp 的算法应该是拿浏览器指纹信息计算得到的指纹, 算法参考见 fingerprint2 库(2.1.4版本), 差不多弄清楚了

[kingwingfly]

@cxw620 Thanks a lot.

I've successfully activated the buvid.

Here's the code:
generate _uuid (refactored)
generate buvid_fp (keep the same)

The response json is

Object {
    "code": Number(0),
    "data": Object {},
    "message": String("0"),
    "ttl": Number(1),
}

So I guess activating successfully.

However, I still cannot use it to invoke like api(https://api.bilibili.com/x/web-interface/archive/like) which I succeeded with cookies(SESSDATA, buvid3) from browser.

Anyone who knows how to deal with it, please kindly tell me how!

Edit: Here's how I invoke like api

[cxw620]

User-Agent? I strongly suggest that you add any headers like a real browser will send.

What's more, showing us codes is good, though an example your programme requesting and getting from upstream will help a lot, too.

[kingwingfly]

User-Agent? I strongly suggest that you add any headers like a real browser will send.

I’m afraid that it is not the cause for my managing to invoke with the cookies from browser, without anything except params, SESSDATA and buvid3.

塑料英语长难句翻译：我恐怕这不是原因，因为我用浏览器的cookie成功调用了，除了params, SESSDATA and buvid3，没有用其他参数。

[cxw620]

I’m afraid that it is not the case for my managing to invoke with the cookies from browser, without anything except params, SESSDATA and buvid3.

I mean http headers, not cookie, I think you must know the difference. Do you think reqwest/0.11.23 is a normal browser's UA?

[kingwingfly]

I’m afraid that it is not the cause for my managing to invoke with the cookies from browser, without anything except params, SESSDATA and buvid3.

我的意思是：复制浏览器中的SESSDATA，buvid3，csrf，不需要UA，是可以成功调用点赞API的。这说明这个API是不检查UA的。

刚才我给激活buvid和点赞都带上了UA，依然不行。返回的还是-403 账号异常,操作失败。

用爬虫的SESSDATA和浏览器的buvid3请求，也是-403，说明二者是绑定的。于是猜测可能是激活的时候信息没带够（Cookie只带了buvid3 buvid4 buvid_fp _uuid）。

然后我又试着带上SESSDATA bili_jct DedeUserID等等，返回的是0，但依然无法用来点赞。实在没辙了。

哈哈，主要是我也习惯在GitHub用英语，关键是自己的英语比较塑料。刚写的那个句子ChatGPT都没翻译对，我的表达有问题，让大佬误解了，所以解释一下。

然后，破案了。是我测试用的视频的up主的问题，换个bv号就好了。

看起来ExClimbWuzhi前的执行的过程是这样的

主站：www.bilibili.com
获得Cookie: buvid3、b_nut

调用数次spi：api.bilibili.com/x/frontend/finger/spi
其中第一次spi获得：b_3、b_4（b_4将被沿用）

ExClimbWuzhi：api.bilibili.com/x/internal/gaia-gateway/ExClimbWuzh
附加cookie：访问主站使用的buvid3和b_nut，第一次调用spi获得的buvid4，以及b_lsid、_uuid、buvid_fp

---

其中，b_lsid的来源依然不明，而第一次调用spi获得的buvid4的参数尾与spi的返回值不同，如果第一次是aaaaa-aaaaa,请求ExClimbWuzhi时就会变成aaaaa-bbbbb，这个差异是怎么造成的？

[cxw620]

b_lsid seems to be generated locally, see here:

buvid4 struct: {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX}-{ DATE INFO }-{ENCRYPTED DATA}

• {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX} => Random string(?)
• { DATE INFO } => yyymmddhh
• {ENCRYPTED DATA} => Generated with IP(?)

b_lsid seems to be generated locally, see here:

buvid4 struct: {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX}-{ DATE INFO }-{ENCRYPTED DATA}

• {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX} => Random string(?)
• { DATE INFO } => yyymmddhh
• {ENCRYPTED DATA} => Generated with IP(?)

谢谢

目前你找到可用的最小cookie组合了吗？根据你说的，buvid3、b_nut、uuid、 buvid4已经可以脱离主站进行模拟了，buvid_fp、b_lsid还不能这样，你在仅有前者的情况下成功通过ExClimbWuzhi的激活过吗？

因为我不知道自己哪里做错了，ExClimbWuzhi一直在返回失败响应

No, I've little interest in web APIs, and I make use of APIs used by offcial APPs, where cookies' not a must.

I strongly suggest that you add all cookies like normal requests do, since risk controlling measures that mikufans may deploy are really a black box and often change over time.

If you do not know the meaning of specific fields in cookies, you can just copy from your own browser, like fingerprint related ones.

I think I've show you how to generate buvid_fp in this issue. As for b_lsid, format!("{}_{:X}", random_string!(len = 8, charset = "0123456789ABCDEF"), now!().as_millis()).

抱歉我记错了，buvid_fp你早就说过了。

我阅读你指出的b_lsid代码后，追溯过其中return (0, n.d8)("b_lsid", r, 0, "same-domain"), r;的n.d8，然后怀疑自己遇到了某种经过混淆的复杂ID生成算法，原来它是随机字符串啊......（或者只是等效于随机字符串）

根据已有的信息，如果buvid4 struct: {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXXXXXXX}-{ DATE INFO }-{ENCRYPTED DATA}中的{ENCRYPTED DATA}不是风险控制必要项，完全模拟的条件好像已经齐备了

你大量使用移动端API时，是不是要面临更艰难的反编译，更多的硬件特征模拟乃至无线电特征模拟？

PS：mikufans 可真是个很硬核的称谓

• n.d8 may be just a func setting cookies.
• You should get buvid3 or buvid4 from offcial API I mention above, instead of generating it locally.
• Of course.

buvid_fp示例代码的输入“FP”中的主要内容如其“canvas fp:data:image/png;base64”所述是canvas指纹，解码后是PNG图片

[xiaofeisi]

看起来ExClimbWuzhi之前的执行过程是这样的

主站：www.bilibili.com 获取Cookie: buvid3、b_nut

调用数次spi：api.bilibili.com/x/frontend/finger/spi 其中第spi获取：b_3、b_4（b_4将被沿用）

ExClimbWuzhi：api.bilibili.com/x/internal/gaia-gateway/ExClimbWuzh 附加cookie：访问主站使用的buvid3和b_nut，第一次调用spi获取的buvid4，以及b_lsid、_uuid、buvid_fp

其中，b_lsid的来源依然不确定，而第一次调用spi获得的buvid4的参数尾部与spi的返回值不同，如果第一次是aaaaa-aaaaa，请求ExClimbWuzhi时就会变成aaaaaa-bbbbb，这个差异是怎么造成的？

buvid4，其他接口可以返回 但是b_lsid、_uuid、buvid_fp 这三个值 有接口返回来吗

See Fingerprintjs2, I've mentioned it above. Not with good measures generating that and I think copy from a real browser will be a good choice...

它们全都是生成的，代码在一楼

近来约半月, 使用 Firefox, 对于 ^(https?://)?(?:[a-zA-Z0-9-]+\.)*bilibili\.com(/.*)?$ 的请求使用 User-Agent 为 curl/7.88.1, 同时 block https://api.bilibili.com/x/internal/gaia-gateway/ExClimbWuzhi data.bilibili.com 的所有请求, 除 v_voucher 验证码以外未见任何异常, 或许 ExClimbWuzhi 的作用并不大
