GraphQL查询可将数据从一台服务器复制到另一台服务器

Question

我有两个具有相同架构的不同端点，我想从一个GraphQL端点读取所有数据，然后将其写入另一个。

https://graphcms.com/服务提供了一个端点，我最近基于https://strapi.io项目在AWS上设置了GraphQL服务器。我想避免使用graphcms上已经存在的数据手动填充新服务器，因此我希望编写两个graphql查询-一个查询以从graphcms端点读取所有节点，然后将其写入另一个端点。

这是目标服务器的完整架构（我只需要填充Microsite类型）：

directive @cacheControl(
  maxAge: Int
  scope: CacheControlScope
) on FIELD_DEFINITION | OBJECT | INTERFACE
enum CacheControlScope {
  PUBLIC
  PRIVATE
}

input createMicrositeInput {
  data: MicrositeInput
}

type createMicrositePayload {
  microsite: Microsite
}

input createRoleInput {
  data: RoleInput

type createRolePayload {
  role: UsersPermissionsRole
}

input createUserInput {

type createUserPayload {
  user: UsersPermissionsUser
}
