Can't look over the APIs

I’m using “localhost:8080/api” to look over the APIs. But the application server log shows “Asset swagger/index.html not found”. Maybe I remove the index.html by accident.

Any help would be appreciated.

Did you compile your own binary, or are you using the pre-compiled binaries?

Sorry to reply to you so late,thanks your help very much!
I was compiling the binary then and mistakenly deleting the swagger file.
