Flask 会话字典重置
Flask session dictionary get reset
同样的方法有效；如果我去掉某个键的特定值。
我有一个名为 'Feature' 的字段，它可以帮助我从亚马逊获取商品描述；我已经通过打印确保它正常工作。这是一个普通的字符串；我已经确定并仔细检查了它。使用类型()
这就是我设置 Flask 会话字典的方式：
app = Flask(__name__)
app.config['SECRET_KEY'] = 'yo'
@app.route('/', methods=['GET','POST'])
def index():
authenticated_url = authenticate(Availability='Available',Operation='ItemSearch',Keywords=str(query),SearchIndex='Electronics', ResponseGroup='ItemAttributes')
product = authenticated_url['ItemSearchResponse']['Items']['Item']
arr = []
for items in product:
main_dictionary = {}
sub_dictionary = {}
sub_dictionary['price'] = items['ItemAttributes']['FormattedPrice']
featureLists = items['ItemAttributes']['Feature']
emptyFeatureStr = ' '
for items in featureLists:
emptyFeatureStr += items
sub_dictionary['Feature']=emptyFeatureStr
main_dictionary[items['ASIN']]=sub_dictionary # I construct a dictionary whose key is ASIN number and values
arr.append(main_dictionary) #I append my new dictionary into an array.
session['searchResults']=arr
print session['searchResults']
#Here I try to set the flask session dictionary key to searchResults
# Verfied/made sure that this is set correct; up until here everything works; my dictionary is set as expected.
问题：
@app.route('/profile/<asin>', methods=['GET','POST'])
def profilePage(asin):
return str(session.get('searchResults')
当我这样做时，它给了我 null。在我摆脱功能的那一刻，它似乎按预期工作……就像显示价格和亚马逊电话一样；烧瓶会话设置正确。我不知道我设置功能的那一刻 key/value 它停止工作了。
这是传递给 feature
