python：

Python3 中可以使用 json 模块来对 JSON 数据进行编解码，它包含了两个函数：

json.dumps(): 对数据进行编码。
json.loads(): 对数据进行解码。
如果你要处理的是文件而不是字符串，你可以使用 json.dump() 和 json.load() 来编码和解码JSON数据。

代码：

 1 #!/usr/bin/python3
 2 # -*- coding: UTF-8 -*-
 3 
 4 # noinspection PyUnresolvedReferences
 5 import io
 6 # noinspection PyUnresolvedReferences
 7 from io import BytesIO
 8 # noinspection PyUnresolvedReferences
 9 import binascii
10 # noinspection PyUnresolvedReferences
11 import json
12 # noinspection PyUnresolvedReferences
13 import numpy
14 
15 if __name__ == '__main__':
16     # print("hello word ... ")
17     # 读取json文件内容,返回字典格式
18     with open('./panorama.json','r',encoding='utf8')as fp:
19         json_data = json.load(fp)
20 
21     outfile = open("./panorama.txt", "r+")
22     #print("json_data['Registration']:",json_data['Registration'])
23     list_data = json_data['Registration']
24     for list_value in list_data:
25         outfile.write(list_value['name'])
26         outfile.write('
')
27         for x in list_value['position']:
28             outfile.write(str(x))
29             outfile.write(' ')
30         outfile.write('
')
31 
32         for x in list_value['eulerangle']:
33             outfile.write(str(x))
34             outfile.write(' ')
35         outfile.write('0.0')
36         outfile.write('
')
37         #print("position :",list_value['position'])
38         #print("eulerangle:",list_value['eulerangle'])
39     fp.close()
40     outfile.close()
