我想将Apollo服务器连接到我具有要查询的模型的“ Python” Lambda服务。我到处搜索,但只能找到使Apollo服务器本身成为AWS Lambda服务的示例。
我创建了一个连接到lambda服务的AWS API网关。
这是我拥有的服务器代码:
const { ApolloGateway, RemoteGraphQLDataSource } = require('@apollo/gateway');
const { ApolloServer, gql } = require('apollo-server');
const gateway = new ApolloGateway({
serviceList: [
{ name: 'clients', url: 'AWS_API_GATEWAY_URL'}
],
buildService({ name, url }){
return new RemoteGraphQLDataSource({
url,
willSendRequest({ request, context }) {
request.http.headers.set(
"user",
context.user ? JSON.stringify(context.user) : null
);
}
});
}
});
const server = new ApolloServer({
gateway,
subscriptions: false
});
server.listen(3000).then(({ url }) => {
console.log(`Server ready at ${url}`);
});
但是即使尝试启动服务器也会出现此错误:Error checking for changes to service definitions: Couldn't load service definitions for "reports" at AWS_GATEWAY_URL
有什么想法吗?
