我最近接触了 C# 语言,并致力于从 cassandra 中获取数据,因此我正在使用下面的代码从 Cassandra 中获取数据并且工作正常。
我唯一的问题是我的ProcessCassQuery方法 - 我传递CancellationToken.None给我的requestExecuter函数,这可能不是正确的做法。处理这种情况的正确方法应该是什么?我应该怎么做才能正确处理?

我想看看如何为这个调用添加超时,以便如果 url 在特定时间内没有响应,那么它应该超时但它可以重试 3 次然后放弃。另外我想看看我如何HttpClient在这里使用而不是WebClient考虑它是一个较旧的 BCL 类而不推荐。
