使用Python Graphene设置一个值并获取多个值

pip install graphene

import graphene

class Value(graphene.ObjectType):
    key = graphene.String()
    value = graphene.String()

class Query(graphene.ObjectType):
    get_value = graphene.Field(Value, key=graphene.String())

    def resolve_get_value(self, info, key):
        # 在这里编写获取值的逻辑，可以从数据库、缓存或其他数据源中获取值
        # 假设我们直接返回一个固定的值
        return Value(key=key, value="Some value")

class SetValue(graphene.Mutation):
    class Arguments:
        key = graphene.String(required=True)
        value = graphene.String(required=True)

    value = graphene.Field(Value)

    def mutate(self, info, key, value):
        # 在这里编写设置值的逻辑，可以将值存储到数据库、缓存或其他数据源中
        # 假设我们只是简单地返回设置的值
        return SetValue(value=Value(key=key, value=value))

class Mutation(graphene.ObjectType):
    set_value = SetValue.Field()

schema = graphene.Schema(query=Query, mutation=Mutation)

query = '''
    query GetValue($key: String!) {
        getValue(key: $key) {
            key
            value
        }
    }
'''

result = schema.execute(query, variables={'key': 'some_key'})
print(result.data['getValue'])
