在pyspark的一行中解析多个json

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

spark = SparkSession.builder.getOrCreate()

data = [
    ('{"name": "John", "age": 30}',),
    ('{"name": "Jane", "age": 25}',),
    ('{"name": "Tom", "age": 35}',)
]
df = spark.createDataFrame(data, ['json'])

schema = StructType([
    StructField('name', StringType(), True),
    StructField('age', StringType(), True)
])

df_parsed = df.withColumn('parsed_json', from_json(df.json, schema))
