Wil*_*ran 2 python google-app-engine json simplejson
我正在尝试将json结果存储在GAE数据存储区中,以便我以后可以读取它.我将它转储到String,然后存储它,然后读取它并将其加载回dict.但是在装载之后我再也不能把它看成dict了.
result = freebase.mqlready(query)

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

呃,看起来你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']
