Record: nailing enterprise internal application dd.httpRequest report errors error:12

Error: the emulator on the PC can be accessed normally, but after it is released online, it will be prompted that error:12 Network error
the company requires the development of nailing add in program, I choose the enterprise internal program, the background is Java, the front end is e application
because I have intranet penetration, so I use it locally!
Both the background and the front end download the demo directly from the official website,

need to write directly

                      authCode:res.authCode
