Question

我正在尝试使用derailed_benchmark gem来跟踪rails应用中的内存泄漏。

当我运行测试时

USE_SERVER=puma bundle exec derailed exec perf:mem_over_time

测试运行直到内存使用率开始趋于平稳，然后测试引发错误：

RuntimeError: Bad request to "curl 'http://localhost:3000/' -s --fail 2>&1" Response:

我该如何解决这个问题？

输出如下：

Answer 1

来自derailed_benchmark团队的help，我发现这是因为我使用rack-attack gem来限制请求。

Answer 2

我有类似的问题

derailed_benchmarks-1.3.4/lib/derailed_benchmarks/tasks.rb:106:in `call_app': Bad request: <html><body>You are being <a href="https://example.org/api/v0/valid">redirected</a>.</body></html> (RuntimeError)

Mine是由仅生产配置引起的，以强制执行SSL：

config.force_ssl=true

或

config.middleware.insert_before ActionDispatch::Static, Rack::SslEnforcer, only_environments: ['production', 'staging']

我评论了这些以解决这个问题
