Answer 1

导入pythons json library：

import json

以字符串形式读入文件，并获取“Response:”子字符串之后的所有内容：

^{pr2}$

从response_string获取python对象：

response_obj = json.loads(response_string)

如果需要，请在对该对象执行所需操作后将其写入文件：

with open("outfile", "w") as out_file:
    out_file.write(json.dumps(response_obj))

Answer 2

使用re.search()和json模块的解决方案：

import re, json

with open('logfile', 'r') as logfile,\
    open('output.json', 'w') as jsonfile:
    json_data = re.search(r'(Response:\s*)(.*)(?=\(HttpClientUtil\))', logfile.read(), re.DOTALL)
    if json_data:
        json.dump(json.loads(json_data.group(2)), jsonfile)

output.json内容：

^{pr2}$
