python - Simplejson 转储和加载不返回有效字典

Question

我正在尝试将 json 结果存储在 GAE 数据存储中，以便稍后读取。我将它转储到一个字符串中，然后存储它，然后读取它并将其加载回字典中。但加载后我无法再将其作为字典阅读。

result = freebase.mqlready(query)

打印结果:

[{u'mid': u'/m/095hd',
  u'name': u'Settlers of Catan',
  u'type': u'/games/game'},
 {u'mid': u'/m/025sm93',
  u'name': u'The Game of Life',
  u'type': u'/games/game'}]

for r in result:
    name = r.name # works, I can get the name and other values.

json_dump = simplejson.dumps(result)
text = db.Text(json_dump)
fbresult = model.FB(text=text)
fbresult.put()
####
stored_text = fbresult.text
json = simplejson.loads(stored_text)

打印 json:

[{u'mid': u'/m/095hd',
  u'name': u'Settlers of Catan',
  u'type': u'/games/game'},
 {u'mid': u'/m/025sm93',
  u'name': u'The Game of Life',
  u'type': u'/games/game'}]

for j in json:
    name = json.name 

错误:

AttributeError: 'dict' object has no attribute 'name'

Answer 1

呃，看起来您正在访问集合而不是内部对象:

当然你的意思是:

for j in json:
    name = j['name']
