这是直接以角度更改构建文件的良好做法吗？

Question

I have some scenario to modify build files after deployment. Is this good practice to change manually?

As per the discussion in the comments, what you want to do is to have different configurations for different environments, there are lots of ways to accomplish this. A built in angular cli way is to use different build configurations . Build configurations have a file replacements option that replaces a file you specify with different variants of it.

In the default scaffold project you can see this pattern with the environments/environment.ts file. You will see a production variant of it with the name environment.prod.ts To have a different api url for production all you have to do is to add the production api url to that file and the development api url to environment.ts For staging, you will have to create a build configuration with a file replacement called environment.staging.ts

The configuration in angular.json would look like this,

"configurations": {
            "production": {
              "fileReplacements": [
                {
                  "replace": ".../environments/environment.ts",
                  "with": ".../environments/environment.prod.ts"
                }
               ]
              ...
              "staging": {
               "fileReplacements": [
                 {
                   "replace": ".../environments/environment.ts",
                   "with": ".../environments/environment.staging.ts"
                  }
                ],
  }

Make sure you always import the api base url from environment.ts and not any of the variants. ng build --configuration staging will do the replacement for you.

Not really, I would make build again and then deploy it. In your case if you do not have time to do all of this and you are sure your changes won't break it then go ahead.
