问题描述
有什么方法可以从 Apollo Server 中的底层 express 应用访问请求对象
推荐答案
上下文配置参数可以是对象，也可以是返回对象的函数，也可以是返回返回对象的promise的函数.该函数将 HTTP 请求作为参数获取，可以这样定义:
const apolloServer = new ApolloServer({
schema,
context: async ({ req }) => {
const something = getSomething(req)
return { something }
},
})
apolloServer.applyMiddleware({ app, path: '/graphql' })
const { appPort } = serviceFunc.getAccessData()
app.listen({ port: appPort }, () => {
console.log(`Express+Apollo Server on http://localhost:${appPort}/graphql`)
})
问题描述
Is there any way of accessing the request object from the underlying express app in Apollo Server
推荐答案
The context configuration parameter can be either an object, a function that returns the object, or a function that returns a promise to return the object. This function would get the HTTP request as a parameter, and could be defined like so:
const apolloServer = new ApolloServer({
schema,
context: async ({ req }) => {
const something = getSomething(req)
return { something }
},
})
apolloServer.applyMiddleware({ app, path: '/graphql' })
const { appPort } = serviceFunc.getAccessData()
app.listen({ port: appPort }, () => {
console.log(`Express+Apollo Server on http://localhost:${appPort}/graphql`)
})
