Apollo4 和 GraphQL CORS

Question

我正在尝试访问生产服务器上的 graphQL 服务器，但收到 CORS 错误。

请求网址为：

https://mov****.at/graphql

在我启动 Apollo 服务器的

index.mjs

中，我将 CORS 定义如下：

app.use(
  '/graphql',
  cors({ origin: ['https://mov***.at', 'https://mov***.at/graphql', 'https://studio.apollographql.com'] }),
  bodyParser.json(),
  expressMiddleware(server),
);

在我的

graphql.module.ts

中，我的 uri 定义如下

const uri = 'https://mov***.at/graphql';

我已阅读> https://www.apollographql.com/docs/apollo-server/security/cors/#configuring-cors-options-for-apollo-server但我没有解决问题。

如果有人遇到这个问题，我已经通过配置我的 nginx 服务器块以接受 CORS 来解决它：

upstream mov***at_upstream_config {
    server 127.0.0.1:4000;
}

upstream mov***at_upstream_graphql_config {
    server 127.0.0.1:4100;
}

server {
  listen 443 ssl http2;
  ssl_certificate /etc/letsencrypt/live/mov***.at/fullchain.pem; # managed by Certbot
  ssl_certificate_key /etc/letsencrypt/live/mov***.at/privkey.pem; # managed by Certbot
  include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
  ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
  server_name www.mov***.at;
  root /root/angular-mov***at/dist/angular-mov***at/browser;

  location / {
    try_files $uri $uri @ssr;
  }

  location @ssr {
    proxy_pass http://mov***at_upstream_config;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_http_version 1.1;
    proxy_set_header X-NginX-Proxy true;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_cache_bypass $http_upgrade;
    proxy_redirect off;
    proxy_set_header X-Forwarded-Proto $scheme;
  }

  location /graphql {
    if ($request_method = 'OPTIONS') {
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
      add_header 'Access-Control-Allow-Credentials' 'true';
      add_header 'Access-Control-Max-Age' 1728000;
      add_header 'Content-Type' 'text/plain charset=UTF-8';
      add_header 'Content-Length' 0;
      return 204;
    }

    proxy_pass http://mov***at_upstream_graphql_config;  # Proxy to your GraphQL server
  }
}

server {
  listen 80;
  server_name www.mov***.at;
  return 301 https://$server_name$request_uri?;
}

我也不需要在 Apollo 服务器文件中指定任何 CORS 配置

app.use(
  cors(),
  bodyParser.json(),
  expressMiddleware(server),
);

更改服务器块后不要忘记重新启动 nginx
