我有一个 graphQL 查询，想将它转换为 GraphQL Transformer v1 到 v2

Question

我正在使用 GraphQl 进行放大处理现有项目 API。

查询将@Key 的问题显示为 Your GraphQL Schema is using "@key" directive from an older version of the GraphQL Transformer。由于我是 graphQL 的新手，我应该改变什么才能让它工作？

谢谢

错误：

✖ An error occurred when pushing the resources to the cloud
 An error occurred during the push operation: Your GraphQL Schema is using "@key" directive from an older version of the GraphQL Transformer. Visit https://docs.amplify.aws/cli/migration/transformer-migration/ to learn how to migrate your GraphQL schema.

AWS 提供了一个迁移指南：https://docs.amplify.aws/cli/migration/transformer-migration/ 但遗憾的是他们没有具体说明如何实际设置您的 API 以使用 new/old 版本。

如果您查看 amplify 文件夹，您会找到一个 cli.json 文件，要将您的后端设置为使用 GraphQLTransformer 版本 1，您只需编辑该文件并设置以下两个属性：

  "features": {
    "graphqltransformer": {
      ...
      "useexperimentalpipelinedtransformer": false,
      "transformerversion": 1,
      ...
    },

从那里您只需 amplify push 并假设您已满足迁移指南描述的所有更改，它将正确更新您的端点。

编辑：对于那些希望升级到 V2 而不是降级到 V1 的用户，您需要按如下方式设置属性：

  "features": {
    "graphqltransformer": {
      ...
      "useexperimentalpipelinedtransformer": true,
      "transformerversion": 2,
      ...
    },
