在 uri 中有 otp 和 message 字段，它们是每个请求的随机值。由于这两个是可变的（总是在变化），我怎样才能忽略 vcr 中的这 2 个字段，以便 vcr 正常工作？

Answer 1

看起来 vcr 有一个内置的解决方案可用于此。

将此添加到 VCR 配置块有效

  config.default_cassette_options = {
      :match_requests_on => [:method,
                             VCR.request_matchers.uri_without_params(:otp, :message)]
  }

这里otp和message是我需要忽略的两件事
