在Python Graphene中使用模式中的不同类型执行嵌套查询

import graphene

class User(graphene.ObjectType):
    name = graphene.String()
    email = graphene.String()

class Query(graphene.ObjectType):
    user = graphene.Field(User)

    def resolve_user(self, info):
        return User(name="John Doe", email="johndoe@example.com")

schema = graphene.Schema(query=Query)

import graphene

class Comment(graphene.ObjectType):
    text = graphene.String()

class Post(graphene.ObjectType):
    title = graphene.String()
    comments = graphene.List(Comment)

class Query(graphene.ObjectType):
    post = graphene.Field(Post)

    def resolve_post(self, info):
        return Post(title="Hello World", comments=[Comment(text="Great post!"), Comment(text="Thanks for sharing!")])

schema = graphene.Schema(query=Query)

import graphene

class Node(graphene.Interface):
    id = graphene.ID()

class User(graphene.ObjectType):
    name = graphene.String()

    class Meta:
        interfaces = (Node,)

class Query(graphene.ObjectType):
    user = graphene.Field(User)

    def resolve_user(self, info):
        return User(name="John Doe")

schema = graphene.Schema(query=Query)

import graphene

class User(graphene.ObjectType):
    name = graphene.String()

class Post(graphene.ObjectType):
    title = graphene.String()

class SearchResult(graphene.Union):
    class Meta:
        types = (User, Post)

class Query(graphene.ObjectType):
    search = graphene.Field(SearchResult, query=graphene.String())

    def resolve_search(self, info, query):
        # Perform search logic here
        return User(name="John Doe")

schema = graphene.Schema(query=Query)
