Problem Description:
The project created using VUE-CLI, the development address is localhost:8080, needs to access the interface on the localhost:8888.
Analysis Reason:
Access between different domain names requires Cross-domain to be properly requested. There are many ways to cross domains, usually requiring background configuration.However, the project created by VUE-CLI can use the Node.js Proxy server directly to implement Cross-domain requests. Solution:
