问题 I want to serve my application though SSL previously I had this script: ng serve --ssl --ssl-key "pathtokey\key.crt" I want to add SSL in the new angular.json but when i try to add it i got the error: Schema validation failed with the following errors: Data path "" should NOT have additional properties(ssl). What is the proper way to use SSL with angular cli 6? 回答1: In angular.json: "serve": { "builder": "@angular-devkit/build-angular:dev-server", "options": { "browserTarget": "app:build",
