@joanwe 没测试过 iPhone 的 dan 哥，现在 dan 哥也改 websocket 包了，估计也抓不到。

@nonoezone 对，西瓜确实有个性题，这个没办法。dan 哥的数据包需要自己多抓几次，它的格式经常变动，但还是有规律的，然后处理成 json，偶尔出错，但基本上还行比较稳定。

@cjy9492 蛋哥的格式如下面，证书没问题的话抓起来不费劲，处理成 json 就行。区分主要在于 step 的值。

@nonoezone 给你提供个思路，下载 app 简单搜索，在里边搜 dan 哥答题，你可以抓他的包，我周六试过了，所有的答题类 app 都能抓到，而且 dan 哥答题的准确率还行，所以只要把 dan 哥的题抓下来然后再调用 selenium 直接百度看网页，跟 dan 哥答案对比，正确率要更高。而且抓 dan 哥的题目一样比正常早出现个 2-3s。
我周六晚上试了一次，总共五次通关，冲顶一次，西瓜两次，好看视频两次，哈哈。
缺点就是两部手机，一部开着简单搜索抓包，另一部答题。

@pheyer 我最开始用 Burp 看的，我也没想出来怎么从 Burp 中导出 websocket 包，但 mitmdump 用 inline 脚本可以截取想要的 websocket，所以我用的是 mitmdump

@chenyoufu123 我之前先用 BurpSuite 抓的，冲顶大会是 websocket 包，数据长度大概 250 左右的就是问题和答案

@ctsed 我说的显示答案是搜索结果的答案:P

刚才冲顶大会测试了下，基本上比 app 早两到三秒显示题目和答案吧
