我们在从配置了keycloak的chrome访问nodejs应用程序时遇到了问题。
Keycloak版本：21.0.1
我们正试图从chrome访问http://localhost:3101/graphql，它显示下面的错误从浏览器控制台。

Access to fetch at 'https://com-dns/realms/dev-realm/protocol/openid-connect/auth?client_id=app-next-bff&state=15b78012-7f01-4176-a7c0-f0b7b6e0c22a&redirect_uri=http%3A%2F%2Flocalhost%3A3101%2Fgraphql%3Fauth_callback%3D1&scope=openid&response_type=code' (redirected from 'http://localhost:3101/graphql') from origin 'http://localhost:3101' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

我们在node js中示例化keycloak时添加了/graphql

const graphqlPath = "/graphql";
        const app = express();
        const corsConfig = {
            credentials: true,
            allowedHeaders: ["Authorization", "Content-Type"],
            exposedHeaders: ["Authorization"],
            origin: true,
        };

        app.use(cors(corsConfig));
        const { keycloak, token } = await configureKeycloak(app, graphqlPath);

        if (!process.env.KEYCLOAK_GENERATED_TOKEN) {
            process.env.KEYCLOAK_GENERATED_TOKEN = token.access_token.token;
        }

        app.use(graphqlPath, keycloak.protect());

有效的重定向URI和Web源配置为**"*"**，我也尝试了http：//ip，但没有运气

我尝试使用机器的IP地址而不是本地主机，并在领域的客户端也更新，但同样存在。
我已经看到了许多关于keycloak的问题，并尝试了它的答案，但没有帮助。
请让我知道如果任何人需要更多的信息。
