我正在解析json数据.解析时我没有问题,我正在使用simplejson模块.但是一些api请求返回空值.这是我的例子:

{
"all" : {
    "count" : 0,
    "questions" : [     ]
    }
}

这是我解析json对象的代码片段:

 qByUser = byUsrUrlObj.read()
 qUserData = json.loads(qByUser).decode('utf-8')
 questionSubjs = qUserData["all"]["questions"]

正如我提到的一些请求,我收到以下错误:

Traceback (most recent call last):

    qUserData = json.loads(qByUser)
