get the path of a specific field in a graphql query

问题

我想获取GraphQL查询中特定参数的路径，并将其返回为列表。

例如，有这样一个查询：

  1. query = '''
  2.     query {
  3.         books {
  4.             __typename
  5.             title
  6.         }
  7.         users {
  8.             __typename
  9.             name
  10.             age
  11.         }
  12.     }
  13. '''

我需要一个Python代码，返回例如"__typename"的路径列表。

像这样：[['books', '__typename'], ['users', '__typename']]

有人可以帮助我吗？

I want to get the path of a specific parameter of a graphql query and return it as a list.

for example, there is query like this:

  1. query = '''
  2.     query {
  3.         books {
  4.             __typename
  5.             title
  6.         }
  7.         users {
  8.             __typename
  9.             name
  10.             age
  11.         }
  12.     }
  13. '''

I need a code in python that returns the path of for example "__typename" in list.

like: [[books, __typename], [users, __typename]]

can someone please give me a hand?

The execution context is available in the Info object.

  1. @strawberry.type
  2. class Query:
  3.     @strawberry.field
  4.     def users(self, info: Info) -> list[User]:
  5.         for field in info.selected_fields:
  6.             print('field', field.name)
  7.             for selection in field.selections:
  8.                 print('  selection', selection.name)
  9.         return []
