implemention

The virtual file system provided by rakyll/statik is used to store files (static files are actually stored in statik.go files in the form of strings), and then a new routing path /dashboard/ is established by using the gin framework to provide static file services.

feature

• modify some front end codes
• Packing (It worked on my own computer)

It's use rakyll/statik library.

• build by Github Actions

problem

• The binary program provided by rakyll/statik is used for packaging, but after executing the go get instruction in GitHub Actions, the program is not in the PATH env and needs to be processed.

Error Message like this:
main.go:18: running "statik": exec: "statik": executable file not found in $PATH
