How nginx solves cross-domain issues

Separate front-end and back-end, use nginx to solve cross-domain problems

Front-end: vue.js nodejs webpack

Backend: SpringBoot

Reverse proxy server: nginx

Idea: Package the front-end code, let nginx point to static resources, and nginx forwards background requests.

1. Package the front-end code:

npm run build

will generate a dist folder. Contains an index.html file and a static folder. Take my local path as an example:

/Users/xxx/ideaProjects/webtest/dist

2. Open

nginx.conf in the /usr/local/etc/nginx directory, add the following to the server:

listen       80; #原为8080，避免冲突，更改为80
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;


        location / {
            root   /Users/xxx/ideaProjects/webtest/dist;
            index  index.html;
            
            # 此处用于处理 Vue、Angular、React 使用H5 的 History时 重写的问题
            if (!-e $request_filename) {
                rewrite ^(.*) /index.html last;
                break;
            }
        }


        # 代理服务端接口
        location /api/ {
            proxy_pass http://localhost:8080/;# 代理接口地址
        }

Test

The front-end sends a request: http://localhost /test, vue-router redirects it to http://localhost/api/demo/1, and the actual access is http://localhost:8080/demo/1.

Send a request directly to the background: visit http://localhost/api/demo/1, the actual visit is: http://localhost:8080/demo/1
