我正在向jsonrpc
服务器发送一些web2py
个请求,并带有celery
后端。有时候,我会收到我想要分析的错误。错误在jsonrpc
回复中被转义,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error.data
回复的jsonrpc
部分,取消它并将其显示为堆栈跟踪。我可以手动执行此操作(更改\"
- > "
并处理\n
),但我想避免在这里重新发明轮子。

这是原始未解析的JSON吗?将其解析为JSON:
import json
print ''.join(json.loads(yourstring)['error']['data'])
