Some functions that are not developed externally only allow intranet access, which can improve security and access speed. For example, some databases only allow the server to connect through the intranet.

3. Intranet penetration solution
①Company-level solutions
a. Developers contact the company's operation and maintenance personnel, access the switch console, and configure internal and external network mapping
② Personal solutions
a. Modify the configuration file hosts of the personal system, and add domain name mapping in the configuration file, but the mapped port must be port 80
b. Using professional internal and external network penetration tools, you can configure the address and port of the internal network, but generally there is a fee
c. Do redirection in the server code of the external network, for example: the external network http://guli.shop/api/ucenter/wx/callback is redirected to
http://localhost:8150/api/ucenter/wx/callback
