我正在设置要使用的开发系统https，Chrome 抱怨我的 websocket 无法安全启动：
VM4965:161 混合内容：“ https://mywebsite.io/ ”页面已通过 HTTPS 加载，但尝试连接到不安全的 WebSocket 端点“ws://mywebsite.io:4000/subscriptions”。此请求已被阻止；此端点必须在 WSS 上可用。
这是我当前的 WS 服务器端设置，基于 Apollo 文档：
const localHostString = 'mywebsite.io';
const pubsub = new PubSub();
// additional context you use for your resolvers, if any
const context = {connectors: connectors};
//SET UP APOLLO QUERY / MUTATIONS / PUBSUB
//start a graphql server with Express handling a possible Meteor current user
createApolloServer({
schema,
context
});
const METEOR_PORT = 3000;
const GRAPHQL_PORT = 4000;
const server = express();
server.use('*', cors({ origin: `https://${localHostString}:${METEOR_PORT}` }));
server.use('/graphql', bodyParser.json(), graphqlExpress({
schema,
context
}));
server.use('/graphiql', graphiqlExpress({
endpointURL: '/graphql',
subscriptionsEndpoint: `ws://${localHostString}:${GRAPHQL_PORT}/subscriptions`
}));
// Wrap the Express server
const ws = createServer(server);
ws.listen(GRAPHQL_PORT, () => {
console.log(`GraphQL Server is now running on http://${localHostString}:${GRAPHQL_PORT}`);
console.log(`GraphiQL available at http://${localHostString}:${GRAPHQL_PORT}/graphiql`);
// Set up the WebSocket for handling GraphQL subscriptions
new SubscriptionServer({
execute,
subscribe,
schema
}, {
server: ws,
path: '/subscriptions',
});
});
如何更新它以使用 WSS 而不是 WS websockets？
提前感谢所有人提供的任何信息。
