如何在我的 Graphql 服务器中添加 cors(Typescript)

Question

我在我的 graphql 服务器中应用 cors 时遇到问题，因为它不起作用，我研究了很多，但仍然无法正常工作。

这是代码：

 import { BasicServer } from 'realm-object-server' import * as path from 'path' import { GraphQLService } from 'realm-graphql-service'`enter code here` import {cors} from 'cors' const server = new BasicServer() server.addService(new GraphQLService({ // Turn this off in production! disableAuthentication: true })) server.start({ // This is the location where ROS will store its runtime data dataPath: path.join(__dirname, '../data'), middlewares: [cors()] }) .then(() => { console.log(`Realm Object Server was started on ${server.address}`) }) .catch(err => { console.error(`Error starting Realm Object Server: ${err.message}`) })

如何在这个graphql服务器中成功应用cors？

我认为您以错误的方式导入 cors，请尝试以下操作：

 import { BasicServer } from 'realm-object-server' import * as path from 'path' import { GraphQLService } from 'realm-graphql-service'`enter code here` import * as cors from 'cors' // <==== const server = new BasicServer() server.addService(new GraphQLService({ // Turn this off in production! disableAuthentication: true })) server.start({ // This is the location where ROS will store its runtime data dataPath: path.join(__dirname, '../data'), middlewares: [cors()] }) .then(() => { console.log(`Realm Object Server was started on ${server.address}`) }) .catch(err => { console.error(`Error starting Realm Object Server: ${err.message}`) })
