以及好像不能删除判题服务器？

  • docker的机制造成的问题，如果使用静态ip会很麻烦，这个如果判题服务器ip变了，手动的编辑一下吧。我也看下看下有没有别的方案。
  • 数据库里面的东西基本上都不能删除，涉及到外键的关联和加锁的问题，处理起来有点麻烦。

感谢支持。

我觉像是你容器里面的进程挂了，要不看下日志？

cjsoft commented May 12, 2016

查到问题了
connection refused 的原因是language.py改的时候改多了一个括号
之后变成了System Error: timed out 是因为token出了问题……
您没写token的长度限制……我就直接sha256sum出来了一个用上了……gg
