解析python中分块的内容类型的响应

Question

I'm trying to read and parse a request of content-type: chunked in python. Here is what I see when I load the url in a browser and look at the source:

<!-- ---------------------------------------------------------------- http://github.com/Atmosphere ------------------------------------------------------------------------ --> 
<!-- Welcome to the Atmosphere Framework. To work with all the browsers when suspending connection, Atmosphere must output some data to makes WebKit based browser working.--> 
<!-- --------------------------------------------------------------------------------------------------------------------------------------------------------------------- --> 
<!-- EOD -->[{"__publicationName":"dip\/acc\/LHC\/Beam\/Intensity\/Beam2","value":"2.505730663333334E9"},  {"__publicationName":"dip\/acc\/LHC\/Beam\/Intensity\/Beam1","value":"1.5584484E9"},{"__publicationName":"dip\/acc\/LHC\/Beam\/Energy","value":"495"},

I'd like to retrieve and parse the json entries like this one:

{"__publicationName":"dip\/acc\/LHC\/Beam\/Intensity\/Beam2","value":"2.505730663333334E9"}

How can I do this?

Thanks

"chunked" is not a valid content-type, although it is a valid transfer-encoding . Based on the sample you've posted, that doesn't really look like your problem. This looks like a header applied to a regular jsonp response. In many cases, the sgml comments would be ignored by a browser, but you'll have to extract it manually for your own use. Here's an idea of dealing with that:

>>> import json
>>> corpus = '''<!-- ---------------------------------------------------------------- http://github.com/Atmosphere ------------------------------------------------------------------------ --> 
... <!-- Welcome to the Atmosphere Framework. To work with all the browsers when suspending connection, Atmosphere must output some data to makes WebKit based browser working.--> 
... <!-- --------------------------------------------------------------------------------------------------------------------------------------------------------------------- --> 
... <!-- EOD -->[{"__publicationName":"dip\/acc\/LHC\/Beam\/Intensity\/Beam2","value":"2.505730663333334E9"},  {"__publicationName":"dip\/acc\/LHC\/Beam\/Intensity\/Beam1","value":"1.5584484E9"},{"__publicationName":"dip\/acc\/LHC\/Beam\/Energy","value":"495"}]'''
>>> junk, data = corpus.split('<!-- EOD -->', 1)
>>> parsed = json.loads(data)
>>> for item in parsed:
...     print item
... 
{u'__publicationName': u'dip/acc/LHC/Beam/Intensity/Beam2', u'value': u'2.505730663333334E9'}
{u'__publicationName': u'dip/acc/LHC/Beam/Intensity/Beam1', u'value': u'1.5584484E9'}
{u'__publicationName': u'dip/acc/LHC/Beam/Energy', u'value': u'495'}
