Question

作为标题我需要从appstore获得评论和费率，日期。我从GitHub获得了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'

似乎日期时间有问题我只想找出问题所在顺便说一句，我的python是2.7.0，我认为是版本问题？

需要帮助

Answer 1

因此，在datetime中，fromtimestamp命令位于date模块中，参见docs。因此，将代码更改为

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

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

仅出于说明的目的，完整的程序就像是

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

返回datetime.date（2017,7,12）

如果您的entry对象返回正确的格式，这应该可行。

我还能通过python获得appstore评论吗？
