python json 加载和 unicode
在以下情况下,我得到了 UTF-8 编码的 HTTP 响应的结果。我想加载响应内容(JSON)。但是我不知道为什么我必须执行 2 个 json.loads 才能获得最终列表:
result = urllib2.urlopen(req).read()
print result, type(result)
#=> "[{\"pk\": 66, \"model\": \"core.job\", \"fields\": {\"customer\": 1, \"created_ts\": \"2010-03-06 06:33:36\", \"log\": 66, \"process\": 1, \"ended_ts\": null, \"state\": \"PENDING\", \"started_ts\": null}}]" <type 'str'>
ret = json.loads(result)
print ret , type(ret)
#=> [{"pk": 66, "model": "core.job", "fields": {"customer": 1, "created_ts": "2010-03-06 06:33:36", "log": 66, "process": 1, "ended_ts": null, "state": "PENDING", "started_ts": null}}] <type 'unicode'>
ret = json.loads(ret)
print ret , type(ret)
#=>[{u'pk': 66, u'model': u'core.job', u'fields': {u'customer': 1, u'created_ts': u'2010-03-06 06:33:36', u'log': 66, u'process': 1, u'ended_ts': None, u'state': u'PENDING', u'started_ts': None}}] <type 'list'>
有什么想法吗?
I have the following case where I get the result of UTF-8 encoded HTTP response. I want to load the response content(JSON). However I don't know why I have to do 2 json.loads
so that I get the final list:
result = urllib2.urlopen(req).read()
print result, type(result)
#=> "[{\"pk\": 66, \"model\": \"core.job\", \"fields\": {\"customer\": 1, \"created_ts\": \"2010-03-06 06:33:36\", \"log\": 66, \"process\": 1, \"ended_ts\": null, \"state\": \"PENDING\", \"started_ts\": null}}]" <type 'str'>
ret = json.loads(result)
print ret , type(ret)
#=> [{"pk": 66, "model": "core.job", "fields": {"customer": 1, "created_ts": "2010-03-06 06:33:36", "log": 66, "process": 1, "ended_ts": null, "state": "PENDING", "started_ts": null}}] <type 'unicode'>
ret = json.loads(ret)
print ret , type(ret)
#=>[{u'pk': 66, u'model': u'core.job', u'fields': {u'customer': 1, u'created_ts': u'2010-03-06 06:33:36', u'log': 66, u'process': 1, u'ended_ts': None, u'state': u'PENDING', u'started_ts': None}}] <type 'list'>
Any ideas?

看起来返回的是 JSON 字符串的
repr()
,而不是 JSON 字符串本身。所以,服务器上有东西坏了。It looks like the
repr()
of the JSON string is what's being returned instead of the JSON string itself. So, something is broken on the server.
