如何在不使用CLI的情况下从Databricks文件系统下载文件？

# 导入必要的库
from pyspark.sql import SparkSession

# 创建SparkSession
spark = SparkSession.builder.getOrCreate()

# 定义要下载的文件路径
dbfs_file_path = "/path/to/file.txt"

# 定义本地文件系统中的目标路径
local_file_path = "/path/to/save/file.txt"

# 使用dbutils.fs.cp()函数将文件从DBFS复制到本地文件系统
spark.conf.set("spark.databricks.service.client.enabled", "true")
spark.conf.set("spark.databricks.service.client.adbToken", spark.conf.get("spark.databricks.service.token"))
spark.conf.set("spark.databricks.service.client.clusterId", spark.conf.get("spark.databricks.service.clusterId"))
spark.conf.set("spark.databricks.service.client.orgId", spark.conf.get("spark.databricks.service.orgId"))
spark.conf.set("spark.databricks.service.client.apiToken", spark.conf.get("spark.databricks.service.apiToken"))

dbutils.fs.cp(dbfs_file_path, local_file_path)
