Symfony將開發人員更改為產品

Question

我有以下問題，我將symfony放在服務器上，將它在app_dev.php調試中更改為false，在app.php中更改為true，現在我應該在信息php bin /控制台中獲取有關我擁有固定版本的信息產品，為什么開發人員總是向我展示？ 當然，調試欄將不會出現，並且進入URL app_dev.php / _profiler下后，我得到一個錯誤

Error: Can not redeclare class Symfony\Component\Debug\ErrorHandler

但是，輸入example.com/_profiler后，出現錯誤：

No route found for "GET /_profiler"

php bin / console關於結果，當我將dev更改為false時，prod為true

如果要在生產服務器或類似服務器中調試代碼，我想說至少有一條黃金法則：不要修改app_dev.php或app.php。 您可以像往常一樣保持prod env，同時，可以在相應的環境（即'dev'，您已經具有“ prod”）和端口下運行Webserver捆綁軟件。 如您所知，代碼中的任何更改都是在dev中即時編譯的，在prod中，您必須清除緩存（甚至賦予適當的Web服務器權限）。 據我了解，您不希望與此有所不同，因此我建議將更改還原到app * .php腳本並相應地運行webserver捆綁軟件。
