Github GraphQL 存储库查询，使用两个对象

Question

查询GithubGraphQL时如何使用多个对象？

如果第二个对象未注释，则以下内容将中断：

query {
  repository(owner:"rails", name:"rails") {
    object(expression:"master") {
      ... on Commit {
        history {
          totalCount
        }
      }
    }
    # object(expression: "master:README.md") {... on Blob {byteSize}}
  }
}

如何让它发挥作用？感谢

使用别名:

query {
  repository(owner:"rails", name:"rails") {
    object(expression:"master") {
      ... on Commit {
        history {
          totalCount
        }
      }
    },
    second_object: object(expression: "master:README.md") {... on Blob {byteSize}}
  }
}
