啟動項目后控制臺出現(xiàn)如下信息，并且頁面內(nèi)顯示Cannot GET /Refused to apply inline style because it violates the following Content Security Policy directive: "default-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-cEmJ9wfQpnZLR35+jGeZk1WmknBbXo0CyiXREeJHUGo='), or a nonce ('nonce-...') is required to enable inline execution. Note also that 'style-src' was not explicitly set, so 'default-src' is used as a fallback.
