首先，确保您已正确配置Airflow和Snowflake的相关内容。您可以尝试以下此代码示例对此问题进行处理：

在Snowflake安装包中，您需要安装以下组：

pip install snowflake-connector-python[pandas] pip install snowflake-connector-python[secure-local-storage]

安装完成后，在您Airflow的DAG文件中，您需要创建一个自定义operator并使用以下Python代码：

from airflow.operators.sensors import BaseSensorOperator from airflow.plugins_manager import AirflowPlugin from airflow.utils.decorators import apply_defaults from airflow import DAG, logging from airflow.contrib.hooks.snowflake_hook import SnowflakeHook from airflow.operators.snowflake_operator import SnowflakeOperator

class SnowflakeConnectionSensor(BaseSensorOperator):

@apply_defaults
def __init__(self, snowflake_conn_id, *args, **kwargs):
    self.snowflake_conn_id = snowflake_conn_id
    super(SnowflakeConnectionSensor, self).__init__(*args, **kwargs)

def poke(self, context):
    hook = SnowflakeHook(self.snowflake_conn_id)

    success = False
    try:
        conn = hook.get_conn()
        cursor = conn.cursor()
        cursor.execute('SELECT 1')
        result = cursor.fetchone()
        if result and result[0] == 1:
            success = True
    except Exception as e:
        logging.error(e)

    return success

dag = DAG('snowflake_connection_test', default_args=default_args) snowflake_conn_id = 'my_snowflake_conn'

snowflake_connection_sensor = SnowflakeConnectionSensor( task_id='snowflake_connection_sensor_task', dag=dag, snowflake_conn_id=snowflake_conn_id )

snowflake_query_task = SnowflakeOperator( task_id='snowflake_query_task', dag=dag, sql='SELECT 1', snowflake_conn_id=snowflake_conn_id )

snowflake_connection_sensor >> snowflake_query_task

将以上代码添加到您的DAG文件后，再次尝试连接Airflow和Snowflake，问题应该就可以得到解决了。
