Can only access index, not hello

Question

Access to http://tp6.io//index/index is normal; Access to http://tp6.io//index/hello prompts that the controller does not exist: app\index\controller\Hello

Answer 1

Module controller method index/hello Isn’t it “index/hello/index”?

Answer 2

http://tp6.io/index/index/hello Just access this for testing. The multiple index should be the path to the index folder. I don’t quite understand it either. If anyone knows, please help me. Thanks!
