写入文件使用--format json参数报错

[Keene-Chen]

根据示例 datafaker file e:\zm\home out1.txt 10 --meta meta.txt --format json报错

Traceback (most recent call last):
File "E:\Scoop\apps\python\current\lib\site-packages\datafaker\cli.py", line 87, in main
args = parse_args()
File "E:\Scoop\apps\python\current\lib\site-packages\datafaker\cli.py", line 65, in parse_args
raise ParamError('rdb not support for json format')
datafaker.exceptions.ParamError: rdb not support for json format
rdb not support for json format

然后我根据拉取请求 #72 修改not in逻辑后，可以正常生成json数据，但是生成的数据又是ASCII不是UTF-8。
希望给个提示，谢谢！

生成数据如下：

{"id": 1, "name": "\u5f20\u5229", "school": "\u5317\u4eac\u5927\u5b66", "nickname": "\u9b3c\u6ce3", "age": 49, "class_num": 82, "score": 86.17, "phone": "15030834802", "email": "[email protected]", "ip": "198.51.47.62", "address": "\u5e7f\u897f\u58ee\u65cf\u81ea\u6cbb\u533a\u6625\u6885\u53bf\u6881\u5e73\u9ad8\u8857N\u5ea7 476777"}

{"id": 2, "name": "\u5510\u6d77\u71d5", "school": "\u5317\u4eac\u5927\u5b66", "nickname": "\u9ad8\u5c0f\u738b\u5b50", "age": 71, "class_num": 12, "score": 42.81, "phone": "14722661894", "email": "[email protected]", "ip": "193.82.145.217", "address": "\u5c71\u4e1c\u7701\u67f3\u53bf\u9521\u5c71\u516d\u76d8\u6c34\u8857x\u5ea7 322680"}

我看到解决办法了😅，后面有同样报错的同学可以尝试修改 #72 和 #78 (comment) 两处的方法，终于解决问题了😴

使用datafaker file e:\zm\home out1.txt 10 --meta meta.txt --format json命令
meta.txt文件内容如下：

id||int||自增id[:inc(id,1)]
name||varchar(20)||学生名字[:name]
school||varchar(20)||学校名字[:enum(清华大学,北京大学)]
nickname||varchar(20)||学生小名[:enum(鬼泣, 高小王子, 歌神, 逗比)]
age||int||学生年龄[:age]
class_num||int||班级人数[:int(10, 100)]
score||decimal(4,2)||成绩[:decimal(4,2,1)]
phone||bigint||电话号码[:phone_number]
email||varchar(64)||家庭网络邮箱[:email]
ip||varchar(32)||IP地址[:ipv4]
address||text||家庭地址[:address]

最后是生成的数据如下：

{"id": 1, "name": "杜梅", "school": "清华大学", "nickname": "高小王子", "age": 25, "class_num": 39, "score": 3.0, "phone": "18556570354", "email": "[email protected]", "ip": "117.54.105.186", "address": "四川省成都市浔阳张街z座 710240"}

{"id": 2, "name": "陈淑英", "school": "清华大学", "nickname": "逗比", "age": 23, "class_num": 89, "score": 51.28, "phone": "13200140438", "email": "[email protected]", "ip": "198.51.59.108", "address": "上海市俊市新城兴城路C座 509477"}

#78修改后报错了
