突然想到的，然后在网上找到了相关代码，可以改，但没必要，程序如下：
（今天除夕，就不多解释了，不难理解，在这里给大家拜个晚年，狗年吉祥）

import itchat
import requests
import time
import random
from itchat.content import *


# 用于记录回复过的好友
replied = []


# 获取新年祝福语
def GetRandomGreeting():
    res = requests.get("http://www.xjihe.com/api/life/greetings?festival=新年&page=10", headers = {'apiKey':'sQS2ylErlfm9Ao2oNPqw6TqMYbJjbs4g'})
    results = res.json()['result']
    return results[random.randrange(len(results))]['words']


# 发送新年祝福语
def SendGreeting(msg):
    global replied
    friend = itchat.search_friends(userName=msg['FromUserName'])
    if friend['RemarkName']:
        itchat.send('自动回复：' + (friend['RemarkName']+','+GetRandomGreeting()), msg['FromUserName'])
    else:
        itchat.send(‘自动回复：' + (friend['NickName']+','+GetRandomGreeting()), msg['FromUserName'])
    #replied.append(msg['FromUserName'])


# 文本消息
@itchat.msg_register([TEXT])
def text_reply(msg):
    if ('年' in msg['Text'] or '除夕' in msg['Text'] or '快乐' in msg['Text'] )and msg['FromUserName'] not in replied:
        SendGreeting(msg)


# 其他消息
@itchat.msg_register([PICTURE, RECORDING, VIDEO, SHARING])
def others_reply(msg):
    if msg['FromUserName'] not in replied:
        SendGreeting(msg)



if __name__ == '__main__':

    itchat.auto_login()
    itchat.run()
