我使用grafana docker容器和Postgresql docker容器。我想我设法向Grafana添加了一个数据源，但是，插件健康检查失败，如下图所示。此外，当我尝试查询时，我得到一个连接错误...

我已经检查过了，我在sql db中创建的用户是一个超级用户，所以它有查询表的权限。在我的python脚本中，我使用grafana http API来添加数据源。

datasource = {
            "name": "postgres",
            "type": "postgres",
            "host": f"http://{database.config.host}",
            "database": database.config.database,
            "user": database.config.user,
            "password": database.config.password,
            "access": "proxy",
            "port": database.config.port,
            "sslmode": "disable",
        }
        headers = {
            "Content-Type": "application/json",
            "Authorization": f"Bearer {self.api_key}",
        }
        response = requests.post(
            self.grafana_url + self.API_DATASOURCES,
            json=datasource,
            headers=headers,
            timeout=2,
        )
