啊这，就是这个接口嘛
http://server.jcdev.cc:52126/get?id=
它是利用这个接口来查题返回结果并处理的 BurYiA 发表于 2022-7-15 10:17

为啥有的题目能自动显示答案，有的显示没有查到，借口不对还是？ 18377194 发表于 2022-7-15 10:20

需要改一下接口吗？ 18377194 发表于 2022-7-15 10:20

题库的问题
当搜索的题目在题库中没有记录的时候自然就无法处理咯
换个脚本用呗，之前用过ocs网课助手 还不错，不清楚现在怎么样，可以试试 BurYiA 发表于 2022-7-15 10:23

这个题库是脚本作者自己建立的，还是服务器上的 18377194 发表于 2022-7-15 10:24

东西肯定是放在服务器上的，题库肯定也是碰不到修改不了的
所以让你换个找的试试嘛，油猴那么多脚本，为啥要死扣一个呢
