nginx反向代理配置访问后台，基础问题？

Question

报错截图如下：

XMLHttpRequest cannot load http://localhost:9090/services/user/login. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 403.

反向代理配置如下：

请问，配置哪里出了问题？

Answer 1

是跨域问题吧，参见/a/11...

Answer 2

server_name 用 localhost 就好，不必带端口，不然 http://localhost:9090/services/ 就转发到 9000 端口了。配置其他部分应该没毛病，提一点建议，nginx配置也贴代码而不是图片就好了，谢谢。

server {
    listen       9090;
    server_name  localhost; // 修改这里
    
    location /front/ {
        proxy_pass http://127.0.0.1:9000/;
    }
    
    location /services/ {
        proxy_pass http://127.0.0.1:8080/services/;
    }
}

Answer 3

根据错误提示，应该是你的 Apache 没有 services/ 目录的访问权限？
是不是项目路径不在 Apache 默认路径下，是的话要做相应的配置

Answer 4

把location /services/ 改成 location /services
