将Spark的数据帧的Json列转换为对象的数组

from pyspark.sql import SparkSession
from pyspark.sql.functions import from_json, col
from pyspark.sql.types import StructType, StructField, StringType, ArrayType

spark = SparkSession.builder.appName("Json to Array").getOrCreate()

schema = StructType([
    StructField("json_column", StringType())
])

df = spark.read.schema(schema).json("path/to/json/file.json")

df = df.withColumn("array_column", from_json(col("json_column"), ArrayType(StringType())))

df.show()
