求助B站评论w_rid获取过程及源码

gentlespider

我想要这个视频的评论
https://www.bilibili.com/video/BV1Sh411b7mM/?spm_id_from=333.999.0.0对应的 评论链接是
https://api.bilibili.com/x/v2/reply/wbi/main?oid=208761519&type=1&mode=3&pagination_str=%7B%22offset%22:%22%22%7D&plat=1&seek_rpid=&web_location=1315875&w_rid=cc7135ca460ff8aa71f8e5f72e987ef5&wts=1695865243
其中有参数oid 我在源码能拿到，wts是时间戳，w_rid 是md5加密的，但不知道传哪些参数
我在网上找了作者主页的w_id 生成过程，但跟这个不一样
求助

R的生成函数，const R = getPictureHashKey(N + U)

[JavaScript] 纯文本查看 复制代码

?

1 2 3 4 5 6 7 8 9

function getPictureHashKey(i) {         const V = [46, 47, 18, 2, 53, 8, 23, 32, 15, 50, 10, 31, 58, 3, 45, 35, 27, 43, 5, 49, 33, 9, 42, 19, 29, 28, 14, 39, 12, 38, 41, 13, 37, 48, 7, 16, 24, 55, 40, 61, 26, 17, 0, 1, 60, 51, 30, 4, 22, 25, 54, 21, 56, 59, 6, 63, 57, 62, 11, 36, 20, 34, 44, 52]           , N = [];         return V.forEach(U=>{             i.charAt(U) && N.push(i.charAt(U))         }         ),         N.join("").slice(0, 32)     }

其中N和U的值为https://api.bilibili.com/x/web-interface/nav   这地址返回的wbi_img里的地址切割过来的，不过应该用它默认的key也行，
wbiImgKey: "839c8b697b0d44dc80e9a604592bb432"
wbiSubKey: "02cd020b04d64aacad6b3a08d06f8eb0"

去搜formatImgByLocalParams

[JavaScript] 纯文本查看 复制代码

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

function formatImgByLocalParams(i, V) {         V || (V = {});         const {imgKey: N, subKey: U} = getImgFormatConfig(V);         if (N && U) {             const R = getPictureHashKey(N + U)               , Z = Math.round(Date.now() / 1e3)               , W = Object.assign({}, i, {                 wts: Z             })               , F = Object.keys(W).sort()               , z = []               , Y = /[!'()*]/g;             for (let D = 0; D < F.length; D++) {                 const X = F[D];                 let P = W[X];                 P && typeof P == "string" && (P = P.replace(Y, "")),                 P != null && z.push(`${encodeURIComponent(X)}=${encodeURIComponent(P)}`)             }             const Q = z.join("&");             return {                 w_rid: md5(Q + R),                 wts: Z.toString()             }         }         return null     }

md5(Q + R)
Q的内容mode=3&oid=208761519&pagination_str=%7B%22offset%22%3A%22%22%7D&plat=1&seek_rpid=&type=1&web_location=1315875&wts=1695865820
R的内容比较复杂没细看
const {imgKey: N, subKey: U} = getImgFormatConfig(V);
然后const R = getPictureHashKey(N + U)

去搜formatImgByLocalParams

[mw_shl_code=javascript,true]function formatImgByLocalParams(i, V) {

大佬能给个R的生成过程吗，感谢
