使用try_files的Nginx无限重定向

Question

我正在尝试使用react-router满足我的路由需求。我尝试将nginx配置为在/ app路由下点击任何内容时使用index.html。但是，当我转到localhost：8000 / app路由时，我继续重定向回localhost：8000 / app。

server {
listen       8000;
server_name  localhost;

#access_log  logs/host.access.log  main;

location /app/ {
    try_files $uri $uri/ /index.html;
    proxy_pass http://127.0.0.1:3001/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_cache_bypass $http_upgrade;
}

location / {
    proxy_pass http://localhost:8888;
    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;
}

#error_page  404              /404.html;

# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
    root   html;
}
}
