Python抓取-无法从Flipkart获取必需的数据

Question

我试图从Flipkart网站上刮取客户评论。以下是链接。以下是我要抓取的代码，但它始终返回一个空列表。

>>> from bs4 import BeautifulSoup
>>> import requests

>>> r = requests.get('https://www.flipkart.com/samsung-galaxy-j5-6-new-2016-edition-white-16-gb/product-reviews/itmegmrnzqjcpfg9?pid=MOBEG4XWJG7F9A6Z')
>>> soup = BeautifulSoup(r.content, 'lxml') # Tried with 'html.parser' also
>>> soup.find_all('div', '_3DCdKt')
[]
>>> soup.find_all('div', {'class': '_3DCdKt'})
[]
>>> soup.find_all('div', {'class': 'row _3wYu6I _3BRC7L'})
[]
>>> soup.find_all('div', {'class': '_1GRhLX hFPo14'})
[]

因此，我尝试获取整个部分，但仅得到以下内容：

>>> soup.find_all('div', {'class': 'col-9-12'})
[<div class="col-9-12" data-reactid="96"><div class="row _2_xtR5" data-reactid="97"></div><div class="row _3wYu6I _1KVtzT" data-reactid="98"></div></div>]

我没有得到其他内容。因此，下一次我尝试使用selenium，即使selenium又回来了None。以下是我的selenium代码：

>>> driver = webdriver.Firefox()
>>> driver.get('https://www.flipkart.com/samsung-galaxy-j5-6-new-2016-edition-white-16-gb/product-reviews/itmegmrnzqjcpfg9?pid=MOBEG4XWJG7F9A6Z')
>>> a = driver.find_elements_by_class_name("_3DCdKt")
>>> len(a)
10
>>> for i in a:
...    print i.get_attribute('value')
...
None

None
None

None

可能是什么问题？我在代码中犯任何错误吗？请帮助。我是Python的新手。

使用 reactjs 填充评论等。使用ajax请求检索数据，您可以将其模拟为请求：

import requests

data = {"productId": "MOBEG4XWJG7F9A6Z", # end of url pid=MOBEG4XWJG7F9A6Z
        "count": "15",
        "ratings": "ALL",
        "reviewerType:ALL"
        "sortOrder": "MOST_HELPFUL"}



headers = ({"x-user-agent":"Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.92 Safari/537.36 FKUA/website/41/website/Desktop"})
data = requests.get("https://www.flipkart.com/api/3/product/reviews", params=data, headers=headers).json()
print(data)

您要访问的data["RESPONSE"]["data"]是字典列表：

for dct in data["RESPONSE"]["data"]
    print(dct)

这会给你：

Gold color and the finishing is super cool\nSize : 100/100 - 5.2 Inch is neither big nor small. I can still operate with one hand.. \nBattery : 100/100 - 3100 mAH is outstanding. 3G is always ON when i am out of home and Wi-Fi is always ON in home. I am charging mobile only once in every 36 hours. I use Whatsapp, instagram and Browsing mostly. \nDisplay : 90/100 - Not so bright and sharp as S series phones, but a real deal for the price. Impressed again. My only worry is about it is not having a Gorilla scratch proof glass. I may need to use tempered glass.\nTouch : 95/100 - So smooth and I dont see any lags as of now.\nCamera : 90/100 - Photos are good and can capture fast, but again not as great as S series phones. but at this price I believe this phone outclasses all other competitors in camera department. \n\nOne last thing is about the SAMSUNG brand and its service center coverage, which is again awesome. \nOverall I am completely satisfied with the phone and this phone reached my expectations. \nWhat I disliked:\nEarphone jack at the bottom.. I feel uncomfortable when chatting and listening to songs at same time\nLow speaker volume, not a big deal though for me, As i don't use loudspeaker for songs mostly", u'reportAbuse': {u'action': {u'originalUrl': None, u'params': {u'vote': u'ABUSE', u'reviewId': u'e786669a-024b-4ef0-b70c-1e4fcf5fe5ff', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 0, u'type': u'VoteValue'}, u'tracking': None}, u'totalCount': 272, u'downvote': {u'action': {u'originalUrl': None, u'params': {u'vote': u'DOWN', u'reviewId': u'e786669a-024b-4ef0-b70c-1e4fcf5fe5ff', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 87, u'type': u'VoteValue'}, u'tracking': None}, u'id': u'e786669a-024b-4ef0-b70c-1e4fcf5fe5ff', u'author': u'Naresh Kareti', u'url': u'/reviews/e786669a-024b-4ef0-b70c-1e4fcf5fe5ff', u'upvote': {u'action': {u'originalUrl': None, u'params': {u'vote': u'UP', u'reviewId': u'e786669a-024b-4ef0-b70c-1e4fcf5fe5ff', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 185, u'type': u'VoteValue'}, u'tracking': None}, u'helpfulCount': 185, u'created': u'13 May, 2016', u'certifiedBuyer': True, u'title': u'Absolute Stunner and Impressive', u'type': u'ProductReviewValue'}, u'tracking': None}

We need to on the screen and check whether it is charging or not. So every time we need to turn it on and see whether it is charging or not.\n* Camera issue: Once you take the picture and then press the back button it is taking some time to come back to camera mode.\n* If you turn on the flash and take pic with back camera it is taking some time to capture the picture. With out Flash it is taking very fast.\n* Volume is very low. Not enough for a medium sized room.\n* Ear phones are not good especially for me. \n\n\nWill post my feedback after using it another 15 days.\n\nThanks', u'reportAbuse': {u'action': {u'originalUrl': None, u'params': {u'vote': u'ABUSE', u'reviewId': u'9cbcd27c-a8ad-4793-978a-5903cd086252', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 0, u'type': u'VoteValue'}, u'tracking': None}, u'totalCount': 212, u'downvote': {u'action': {u'originalUrl': None, u'params': {u'vote': u'DOWN', u'reviewId': u'9cbcd27c-a8ad-4793-978a-5903cd086252', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 67, u'type': u'VoteValue'}, u'tracking': None}, u'id': u'9cbcd27c-a8ad-4793-978a-5903cd086252', u'author': u'ileep ', u'url': u'/reviews/9cbcd27c-a8ad-4793-978a-5903cd086252', u'upvote': {u'action': {u'originalUrl': None, u'params': {u'vote': u'UP', u'reviewId': u'9cbcd27c-a8ad-4793-978a-5903cd086252', u'reviewDomain': u'PRODUCT'}, u'loginType': u'LEGACY_LOGIN', u'url': None, u'fallback': None, u'type': u'REVIEW_VOTE', u'omnitureData': None, u'screenType': None, u'tracking': {}}, u'fixed': False, u'value': {u'count': 145, u'type': u'VoteValue'}, u'tracking': None}, u'helpfulCount': 145, u'created': u'16 May, 2016', u'certifiedBuyer': True, u'title': u'Good looking phone with some drawbacks', u'type': u'ProductReviewValue'}, u'tracking': None}
