我将带有celery
后端的web2py
服务器发送一些jsonrpc
请求。有时,我会发现我想分析的错误。jsonrpc
回复中逃脱了这些错误,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_jsonrpcn s = methods[method](*params)n", " File "/home/myuser1/tmp/web2py/applications/mycompany_portal/controllers/activity.py", line 66, in get_cdr_pagen 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_pagen 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 getn interval=interval)n", " File "/home/myuser1/.virtualenvs/python2.7.2-mycompany1/lib/python2.7/site-packages/celery/backends/amqp.py", line 138, in wait_forn raise self.exception_to_python(meta['result'])n"], "name": "JSONRPCError"}}
我想要的是获取jsonrpc
的error.data
部分答复,取消示例并显示为堆栈Trace。我可以手动执行(更改"
-> "
并处理n
),但我想避免在此处重新发明轮子。
这是原始的无与伦比的JSON吗?将其解析为JSON:
import json
print ''.join(json.loads(yourstring)['error']['data'])
重新编辑:
使用:
UnQuote

或
unquote_plus
http://docs.python.org/2/library/urllib.html#urllib.unquote_plus
用于Unescape-ing类似于HTTP的数据(即百分比删除)
