Python从请求中打印json数据

我一直在摸不着为什么它不打印我需要的json内容。谁知道我做错了什么?

这是字典

> "listinginfo": {
>     "438309609514180554": {
>       "listingid": "438309609514180554",
>       "price": 35,
>       "fee": 4,
>       "publisher_fee_app": 730,
>       "publisher_fee_percent": "0.10000000149011612",
>       "currencyid": "2003",
>       "steam_fee": 1,
>       "publisher_fee": 3,
>       "converted_price": 50,
>       "converted_fee": 7,
>       "converted_currencyid": "2020",
>       "converted_steam_fee": 2,
>       "converted_publisher_fee": 5,
>       "converted_price_per_unit": 50,
>       "converted_fee_per_unit": 7,
>       "converted_steam_fee_per_unit": 2,
>       "converted_publisher_fee_per_unit": 5,
>       "asset": {
>         "currency": 0,
>         "appid": 730,
>         "contextid": "2",
>         "id": "1579403640",
>         "amount": "1",
>         "market_actions": [
>           {

代码+我需要我想要打印的键的值:

while 1:
    r = requests.get(url, headers=headers)
    listingInfoStr = r.content
    result= ujson.loads(listingInfoStr)
    listingInfoJson= result['listinginfo']
    for listingdata in listingInfoJson: 
        print listingdata.get('listingId')
        print listingdata.get('subTotal') 
        print listingdata.get('feeAmount')
        print listingdata.get('totalPrice')
    time.sleep(10)

感谢您的时间。

您可以使用requests.Response.json方法来解析JSON:

r = requests.get(url, headers=headers)
listingInfoJson = r.json()['listinginfo']

我运行了你的代码,它看起来像listingInfoJson作为dict返回而不是列表。因此,当你迭代它时,它只是拉动键。

您在unicode对象上调用.get方法,这会给您一个AttributeError。您可以通过不同的方式运行此代码:

for listingdata in listingInfoJson: 
    print listingInfoJson[listingdata].get('listingid')
    print listingInfoJson[listingdata].get('subTotal') 
    print listingInfoJson[listingdata].get('feeAmount')
    print listingInfoJson[listingdata].get('totalPrice')

或更好的方式(编辑评论):

if listingInfoJson:
    for key, value in listingInfoJson.iteritems():
        print value.get('listingid')
        print value.get('subTotal') 
        print value.get('feeAmount')
        print value.get('totalPrice')
else:
    print "listingInfoJson is empty"

我还要检查您的关键值,listingId应为listingid
