#C++调用python

本文介绍了如何使用C++调用Python脚本来操作Kafka，包括Python编写Kafka的consumer和producer，以及在Linux环境下C++通过g++编译并执行调用Python的程序。

1.python操作kafka的代码：

import sys
import time
import json

from kafka import KafkaProducer
from kafka import KafkaConsumer
from kafka.errors import KafkaError


KAFAKA_HOST = "127.0.0.1"
KAFAKA_PORT = 9092
KAFAKA_TOPIC = "test"


class Kafka_producer():

    def __init__(self, kafkahost,kafkaport, kafkatopic):
        self.kafkaHost = kafkahost
        self.kafkaPort = kafkaport
        self.kafkatopic = kafkatopic
        print("producer:h,p,t",kafkahost,kafkaport,kafkatopic)
        bootstrap_servers = '{kafka_host}:{kafka_port}'.format(
                kafka_host=self.kafkaHost,
                kafka_port=self.kafkaPort
                )
        print("boot svr:",bootstrap_servers)
        self.producer = KafkaProducer(bootstrap_servers = bootstrap_servers
                )

    def sendjsondata(self, params):
        try:
            parmas_message = json.dumps(params,ensure_ascii=False)
            producer = self.producer
            print(parmas_message)
            v = parmas_message.encode('utf-8')
            print("send msg:(v)",v)
            producer.send(self.kafkatopic, value= v)
            producer.flush()
        except KafkaError as e:
            print (e)

class Kafka_consumer():

    def __init__(self, kafkahost
