如何使用linux将kapacitor中的多个值存储到python变量中？

import http.server
import json

data = []

class RequestHandler(http.server.BaseHTTPRequestHandler):
    def do_POST(self):
        content_length = int(self.headers['Content-Length'])
        post_data = self.rfile.read(content_length)
        json_data = json.loads(post_data.decode('utf-8'))
        
        # 处理接收到的数据，并将其存储到变量中
        # 这里假设数据是一个列表，存储在json_data的"data"字段中
        if 'data' in json_data:
            data.extend(json_data['data'])
        
        self.send_response(200)
        self.end_headers()

server_address = ('', 8000)
httpd = http.server.HTTPServer(server_address, RequestHandler)
httpd.serve_forever()

stream
    |from()
        .measurement('measurement')
        .where(lambda: TRUE)
    |httpOut()
        .url('http://localhost:8000')
        .method('POST')
