python - 解析Python中分块的内容类型的响应

Question

我正在尝试读取并解析内容类型的请求:在 python 中分块。以下是我在浏览器中加载 url 并查看源代码时看到的内容:

<!-- ---------------------------------------------------------------- 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"},

我想检索并解析如下所示的 json 条目:

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

我该怎么做？

谢谢

“chunked”不是有效的内容类型，尽管它是有效的 transfer-encoding 。根据您发布的示例，这看起来并不是您的问题。这看起来像是应用于常规 jsonp 响应的 header 。在许多情况下，浏览器会忽略 sgml 注释，但您必须手动提取它以供自己使用。这是处理这个问题的想法:

>>> 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'}
