我正在向 web2py 服务器发送一些 jsonrpc 请求，后端是 celery。有时，我会收到要分析的错误。错误在jsonrpc 回复中转义，因此不容易理解。我得到这样的东西:
{"version": "1.1", "id": "ID4", "error": {"message": "TypeError: 'NoneType' object does not support item assignment", "code": 100, "data": [" File \"/home/myuser1/tmp/web2py/gluon/tools.py\", line 4068, in serve_jsonrpc\n s = methods[method](*params)\n", " File \"/home/myuser1/tmp/web2py/applications/mycompany_portal/controllers/activity.py\", line 66, in get_cdr_page\n invalidate_cache = pars['invalidate_cache'], use_long_polling = pars['use_long_polling'])\n", " File \"/home/myuser1/projects/new-mycompany-portal/python_modules/pmq_client.py\", line 85, in get_page\n res = result.get(timeout=10)\n", " File \"/home/myuser1/.virtualenvs/python2.7.2-mycompany1/lib/python2.7/site-packages/celery/result.py\", line 119, in get\n interval=interval)\n", " File \"/home/myuser1/.virtualenvs/python2.7.2-mycompany1/lib/python2.7/site-packages/celery/backends/amqp.py\", line 138, in wait_for\n raise self.exception_to_python(meta['result'])\n"], "name": "JSONRPCError"}}
我想要的是获取 jsonrpc 回复的 error.data 部分，将其取消转义并将其显示为堆栈跟踪。我可以手动完成(更改 \" -> " 并处理 \n)，但我想避免在这里重新发明轮子.
最佳答案
这是未解析的原始 JSON 吗？将其解析为 JSON:
import json
print ''.join(json.loads(yourstring)['error']['data'])
