python 从请求响应中提取元素

Question

i received this from an http request:

{u'accountDirectDialId': u'...', u'number': u'...', u'messageType': u'simple_message', u'configData': {u'audios': {u'message_audio': {u'duration': None, u'hashFile': u'...', u'id': u'16990559-acb9-11ea-af69-522c847d095a', u'name': None, u'uri': u'https://...'}}}, u'inboundCallerId': u'...', u'maxDestinationRetry': 1, u'hasVoicemail': False, u'voIp': {u'codePhone': 00}, u'hasMessage': True}

This is stored in a var.

Then if i do this, this works perfectly:

myvar["configData"]["audios"]["message_audio"] 

But if i go one step further:

myvar["configData"]["audios"]["message_audio"]["uri"] 

This fails miserably? Why does this happen: uri is simply a parameter in "message_audio" when i do this:

print('Audio URI: "%s"\n' % type(myvar["configData"]["audios"]) )

I'm getting

Python Error by calling script "mass": <type 'exceptions.TypeError'>
Message: string indices must be integers, not str
Exception: None

Traceback (most recent call last)

Output should be

'https://...'

Can anyone help?

UPDATE:

printing:

One level above: print('[%s]: Audio URI: "%s"\n' % (session_sip_call_id, type(CData.get("configData",None).get("audios",None).get("message_audio",None)) ) )

Prints: Audio URI: ""

But: print('[%s]: Audio URI: "%s"\n' % (session_sip_call_id, type(CData.get("configData",None).get("audios",None).get("message_audio",None).get("uri",None)) ) )

returns:

Audio URI: "<type 'unicode'>"

thanks!

Answer 1

What version of Python do you use?

In Python 2, Unicode needed to be converted But in Python 3, this is done automatically, however you can use the following code snippet:

uni_var = str(myvar["configData"]["audios"]["message_audio"]["uri"])

print(uni_var)
