我正在编写一个使用Open3调用perl脚本的Ruby on Rails应用程序。然而，当调用perl脚本时，我的应用程序不断抛出超时::错误比我想要的更快。我调用脚本的代码如下所示:
Timeout::timeout(120){
@stdout, @stderr, @exit_code = Open3.capture3(@command)
[@exit_code.to_i, @stdout, @stderr]
}
我意识到调用一个潜在的"长"运行脚本(可能最多20-30秒)对于ruby on rails应用程序来说并不理想，但我没有太多的选择。
我使用独角兽来获得并发性，我将独角兽超时设置为60s。尽管我的独角兽文件中有60秒超时，Open3调用中有120秒超时，但我的请求始终超时在18秒左右。我知道脚本成功完成，因为我看到另一边的结果，但我需要我的应用程序等待脚本的返回。
是否有其他方法可以强制我的rails应用程序等待而不是超时?
谢谢!
