How nginx solves cross-domain request issues

一般前端的请求是 网址都是 域名(端口 访问的是80 或者 443),而后端的服务是 8080 端口,这个时候你请求http://106.520.156.210:8080/vic-indoor-pc/selectAllUser就会报跨域问题了(端口不同)。所以我在每个请求加了统一的前缀 /api ,请求变成了 http://106.520.156.210/api/vic-indoor-pc/selectAllUse (端口必须和前端一样)。

前端发送请求:

http://106.520.156.210/api/vic-indoor-pc/selectAllUse
Copy after login

Nginx转发变成了:

http://106.520.156.210:8080/vic-indoor-pc/selectAllUse
Copy after login

经过Nginx 这样转发,对于浏览器来说,访问的就是 80 ,但是请求的其实是 8080。rewrite "^/api/(.*)$" /$1 break; 这句就是把 /api 给删除掉了然后 转发到了 http://106.520.156.210:8080/

                location /api/vic-indoor-pc {

                        proxy_set_header Client-IP      $Remote_addr;
                        proxy_pass http://106.520.156.210:8080/;
                        rewrite "^/api/(.*)$" /$1 break; 

                }
Copy after login

我还碰到了下载阿里OSS 存储跨域的问题,也是这么解决的。(加上统一前缀)

                location /img/report {

                        proxy_set_header Client-IP      $Remote_addr;
                        proxy_pass https://bilibili.oss-cn-shenzhen.aliyuncs.com/;
                        rewrite "^/img/(.*)$" /$1 break;
                }
Copy after login
