我使用 react 作为前端，使用 nodejs 作为后端，在 localhost:3016 上运行，使用 nginx 作为反向代理和负载均衡器；这是我网站的 nginx conf 文件

I get this error

我找到了该问题的解决方案，并且我相信分享该解决方案将对其他人有所帮助，请使用这个'proxy_set_header Content-Security-Policy upgrade-insecure-requests；下面是我配置的方式
location /api {
proxy_pass http://load_balance;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_read_timeout 3600;
proxy_headers_hash_max_size 512;
proxy_headers_hash_bucket_size 128;
proxy_set_header Content-Security-Policy upgrade-insecure-requests;
希望你觉得它有用！
