将指定json格式的内容，写入文件中，构造测试数据

import sys
import datetime
import random
import string
import time

target = open("testdata.txt", 'a')
#指定需要产生多少条json数据
for i in range(100):
    now = datetime.datetime.now()
    now_time = now.strftime('%Y-%m-%d %H:%M:%S')
    today = now.strftime('%Y-%m-%d')
    add_time = ''.join(random.sample(string.digits, 10))
    data="{\"log_ds\": \"" + today + "\"," + "\"log_id\": \"addfriend\", \"log_ts\": \"" + now_time + "\"," + "\"region\": 1, \"server\": \"6\", \"add_time\": " + add_time + "," + "\"host_pid\": \"1419395816029523974\", \"friend_pid\": \"1210342673502494726\", \"friend_count\": 1, \"adddouble.test\": 1.25}"

    print(data)
    target.writelines(str(data) + '\n')
    time.sleep(0.01)
target.close()
