利用python将csv（UTF-8编码）转化为json格式，但是转化为json格式后，在使用时会UFT-8报错

利用python将csv（UTF-8编码）转化为json格式，方便后续使用，但是转化为json格式后，在使用时会UFT-8报错，不知道怎么回事
csv转换成json的代码如下

```python
# -*- coding:utf-8 -*-
import pandas as pd
import numpy as np
import json
import collections

first_data = pd.read_csv('F:\pachong\CNKI_抖振报警.csv', encoding='UTF-8')
print(first_data.head())

f = open("报警优化.json", "w+")
for i in range(len(first_data)):
    data_dict = collections.OrderedDict()  ##利用OrderedDict()建立有序词典
    data_dict['article'] = first_data.loc[i, '文章']
    data_dict['author'] = first_data.loc[i, '一作']
    data_dict['all_author'] = first_data.loc[i, '所有作者']
    data_dict['source'] = first_data.loc[i, '来源']
    data_dict['time'] = str(first_data.loc[i, '时间'])
    data_dict['database'] = first_data.loc[i, '数据库']
    data_dict['keywords'] = first_data.loc[i, '关键字']
    data_dict['abstract'] = first_data.loc[i, '摘要']
    data_dict['direction'] = first_data.loc[i, '研究方向']
    data_dict['link'] = first_data.loc[i, '链接']


    # 使用json模块将构造好的字典保存到文件中
    # data_dict.encode("utf-8")
    f.writelines(json.dumps(data_dict, ensure_ascii=False, indent=4) + ',\n')
f.close()  # 将文件关闭



此处代码参考：https://blog.csdn.net/ziyin_2013/article/details/113779616```

生成的json文件内容如下（截取一部分）

```python

{
    "article": "啊",
    "author": "啊",
    "all_author": "啊",
    "source": "啊",
    "time": "啊",
    "database": "啊",
    "keywords": "啊",
    "abstract": "啊",
    "direction": "啊",
    "link": "啊"
},
{
    "article": "啊",
    "author": "啊",
    "all_author": "啊",
    "source": "啊",
    "time": "啊",
    "database": "啊",
    "keywords": "啊",
    "abstract": "啊",
    "direction": "啊",
    "link": "1"
}
报错内容如下：
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 2 column 1 (char 2)

```

只需要在你的数据文件头和尾加对中括号就好，变成数组就能读了

f = open("报警优化.json", "w+")
f.writeline('[')
for i in range(len(first_data)):
    data_dict = collections.OrderedDict()  ##利用OrderedDict()建立有序词典
    data_dict['article'] = first_data.loc[i, '文章']
    data_dict['author'] = first_data.loc[i, '一作']
    data_dict['all_author'] = first_data.loc[i, '所有作者']
    data_dict['source'] = first_data.loc[i, '来源']
    data_dict['time'] = str(first_data.loc[i, '时间'])
    data_dict['database'] = first_data.loc[i, '数据库']
    data_dict['keywords'] = first_data.loc[i, '关键字']
    data_dict['abstract'] = first_data.loc[i, '摘要']
    data_dict['direction'] = first_data.loc[i, '研究方向']
    data_dict['link'] = first_data.loc[i, '链接']


    # 使用json模块将构造好的字典保存到文件中
    # data_dict.encode("utf-8")
    f.writelines(json.dumps(data_dict, ensure_ascii=False, indent=4) + ',\n')
f.writeline(']')
f.close()  # 将文件关闭
