我是Pyspark的新手。从下面的代码中，我想创建一个spark数据框。很难以正确的方式来解析它。

1. 如何以正确的方式在数据框中解析它？

2. 我如何解析它并获得以下输出？
   //
   所需的输出：

           date_added|              price|
   +--------------------+--------------------+
   |          2020-11-01|              10000|
   

代码：

conf = SparkConf().setAppName('rates').setMaster("local")
sc = SparkContext(conf=conf)

url = 'https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest'
parameters = {
      'symbol': 'BTC',
      'convert':'JPY'
}
headers = {
  'Accepts': 'application/json',
  'X-CMC_PRO_API_KEY': '***********************',
}

session = Session()
session.headers.update(headers)
try:
  response = session.get(url, params=parameters)
  json_rdd = sc.parallelize([response.text])
    #data = json.loads(response.text)
  #print(data)
except (ConnectionError, Timeout, TooManyRedirects) as e:
  print(e)


sqlContext = SQLContext(sc)
json_df = sqlContext.read.json(json_rdd)
json_df.show()

输出数据帧：

|                data|              status|
+--------------------+--------------------+
|[[18557275, 1, 20...|[1, 18, 0,,, 2020...|
