解决Pandas to_json()中文乱码,转化为json数组的问题

df1 = pd.DataFrame(pd.read_excel(u'excel/袁隆平院士报告处理后.xlsx'))
js001 = df1.to_json(force_ascii=False)
with open('json/testjson.json', 'w') as f:
 f.write(js001)
# "16":6,"17":6,"18":3,"19":4},"content":{"0":"研究调改王玉田院士项目入驻协议，完成签约仪式方案","1":"\u5b
#处理后
df1 = pd.DataFrame(pd.read_excel(u'excel/袁隆平院士报告处理后.xlsx'))
dfts = DataFrameToJSONArray(df1, 'json/wyt_xyz.json') # 参数(df数据,文件存储路径)
dfts.funChangeDataFrameType() # 自动转换DataFrame的列数据类型
dfts.funSaveJSONArrayFile() # 存储JSON格式文件
# [["2016-08-08", "袁隆平院士观摩指导"], ["2016-08-09","修改完善袁隆平院士项目合作协议"],["2016-08-10","完成袁隆平院士合作协议"],["2016-08-31","袁隆平院士项目入驻院士港协议审核完毕"],....]
