我还能通过python获得应用商店评论吗?

Question

作为标题，我需要从应用商店获取评论和费率，日期。 我从 GitHub 得到了 github.com/don9z/appstore

这是代码：

import feedparser
from datetime import datetime
import calendar
app_contries = {
'China':'cn',
'United States':'us'}
app_sortby = {
'Most Recent':'mostRecent',
'Most Helpful':'mostHelpful',
# 'Most Favorable':'mostFavorable',
# 'Most Critical':'mostCritical'}
def mk_appfeed(app_id, country_code, sortby=app_sortby['Most Recent']):
return 'https://itunes.apple.com/%s/rss/customerreviews/id=%s/sortBy=%s/xml' %
(country_code,app_id, sortby)
def parse_feed(url):
review_map = {}
feed = feedparser.parse(url)
review_map.setdefault('title', feed.feed['title'])
review_map.setdefault('updated',
calendar.timegm(feed.feed['updated_parsed']))
if not feed.entries:
print 'Get nothing from ' + url
return None
review_map.setdefault('apptitle', feed.entries[0]['title'])
review_map.setdefault('applink', feed.entries[0]['id'])
reviews = []
for entry in feed.entries[1:]:
reviews.append({'title': entry['title'],
'content': entry['content'][0]['value'],
'author': entry['author'],
'rating': entry['im_rating'],
'updated': calendar.timegm(entry['updated_parsed'])
})
review_map.setdefault('reviews', reviews)
return review_map
def print_reviews(review_map):
if not review_map:
print 'Input None'
return
print 'Title:    %s' % review_map['title']
print 'Updated:  %s' % datetime.fromtimestamp(review_map['updated'])
print 'App Name: %s' % review_map['apptitle']
print 'Link:     %s' % review_map['applink']
index = 0
for entry in review_map['reviews']:
index+=1
print '*** %d ***' % index
print 'Title:    %s' % entry['title']
print 'Content:  %s' % entry['content']
print 'Author:   %s' % entry['author']
print 'Rating:   %s' % entry['rating']
print 'Updated   %s' % datetime.fromtimestamp(entry['updated'])
def get_app_reviews(app_id, country_name, sortby='Most Recent'):
print_reviews(parse_feed(mk_appfeed(app_id, app_contries[country_name],
app_sortby[sortby])))

我只是使用 call.py

import review
review.get_app_reviews('506627515', 'United States')

但命令返回

Title:    iTunes Store: Customer Reviews
Traceback (most recent call last):
File "call.py", line 3, in <module>
review.get_app_reviews('506627515', 'United States')
File "/Users/Eric/Desktop/appstore-master/review.py", line 71, in get_app_reviews
app_sortby[sortby])))
File "/Users/Eric/Desktop/appstore-master/review.py", line 54, in print_reviews
print 'Updated:  %s' % datetime.fromtimestamp(review_map['updated'])
AttributeError: 'module' object has no attribute 'fromtimestamp'

日期时间似乎有问题 我只是想找出问题出在哪里 顺便说一下，我的 Python 是 2.7.0，我认为是版本问题吗？

需要帮助

所以在datetime中，fromtimestamp命令在date模块中，参见文档。因此，将您的代码更改为

import datetime
print 'Updated:  %s' % datetime.date.fromtimestamp(review_map['updated'])

请注意，review_map中的项目是由calendar.timegm()创建的，它返回一个 Unix 时间戳，参见 docs。

仅出于说明目的，完整的过程类似于

datetime.date.fromtimestamp(calendar.timegm(time.gmtime()))

返回日期时间.日期(2017， 7， 12(

如果entry对象返回正确的格式，这应该可以工作。
