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) + '
')
    time.sleep(0.01)
target.close()
