返回多个项目
返回多个项目
提问于 2018-11-02 00:42:59
我是python的新手，事实上，这是我的第一个python项目。我正在使用ebaysdk在ebay上搜索电子产品，我希望它返回多个结果，因为我的应用程序是用来比较价格的，但它只返回一个结果。
谁能帮我让代码返回多个结果。
这是我的代码片段。
@app.route('/ebay_page_post', methods=['GET', 'POST'])
def ebay_page_post():
if request.method == 'POST':
#Get json format of the text sent by Ajax
search = request.json['search']
try:
#ebaysdk code starts here
api = finding(appid='JohnOkek-hybridse-PRD-5c2330105-9bbb62f2', config_file = None)
api_request = {'keywords':search, 'outputSelector': 'SellerInfo', 'categoryId': '293'}
response = api.execute('findItemsAdvanced', api_request)
soup = BeautifulSoup(response.content, 'lxml')
totalentries = int(soup.find('totalentries').text)
items = soup.find_all('item')
for item in items:
cat = item.categoryname.string.lower()
title = item.title.string.lower().strip()
price = int(round(float(item.currentprice.string)))
url = item.viewitemurl.string.lower()
seller = item.sellerusername.text.lower()
listingtype = item.listingtype.string.lower()
condition = item.conditiondisplayname.string.lower()
print ('____________________________________________________________')
#return json format of the result for Ajax processing
return jsonify(cat + '|' + title + '|' + str(price) + '|' + url + '|' + seller + '|' + listingtype + '|' + condition)
except ConnectionError as e:

根据您提供的代码，添加了您可以使用的键值对集合示例：
@app.route('/ebay_page_post', methods=['GET', 'POST'])
def ebay_page_post():
if request.method == 'POST':
#Get json format of the text sent by Ajax
search = request.json['search']
try:
#ebaysdk code starts here
api = finding(appid='JohnOkek-hybridse-PRD-5c2330105-9bbb62f2', config_file = None)
api_request = {'keywords':search, 'outputSelector': 'SellerInfo', 'categoryId': '293'}
response = api.execute('findItemsAdvanced', api_request)
soup = BeautifulSoup(response.content, 'lxml')
totalentries = int(soup.find('totalentries').text)
items = soup.find_all('item')
# This will be returned
itemsFound = {}
# This index will be incremented
# each time an item is added
index = 0
for item in items:
cat = item.categoryname.string.lower()
title = item.title.string.lower().strip()
price = int(round(float(item.currentprice.string)))
url = item.viewitemurl.string.lower()
seller = item.sellerusername.text.lower()
listingtype = item.listingtype.string.lower()
condition = item.conditiondisplayname.string.lower()
# Adding the item found in the collection
# index is the key and the item json is the value
itemsFound[index] = jsonify(cat + '|' + title + '|' + str(price) + '|' + url + '|' + seller + '|' + listingtype + '|' + condition)
# Increment the index for the next items key
index++
for key in itemsFound:
print key, ':', itemsFound[key
# return itemsFound
except ConnectionError as e:

找到第一项后，将其添加到集合中。在for循环结束后，返回集合。
现在，一旦你找到了第一个，你就会返回(中断迭代)
