python发送avro文件

生成avro文件，并写入二进制，使用python2，python3需要适配修改

1.avsc文件schema格式：

文件名：type111.avsc

{
    "type": "record",
    "name": "test",
    "fields": [
        {"name": "version", "type": "string"},
        {"name": "name", "type": "string"},
        {"name": "card", "type": "string"}
    ]
}

 2. 代码示例

#! -*- coding:utf-8 -*
import json
import os
import time
from io import BytesIO

import avro
from avro.datafile import DataFileWriter
from avro.io import DatumWriter, BinaryEncoder

# avsc文件夹，schema
avsc_dir = r"E:\avro_data\avsc_data"
# 生成的avro文件夹
avro_dir = r"E:\avro_data\data"


def generate_avro_file(data_list, schema_type):
    """
    生成AVRO
    :param data_list: 要写入的数据列表
