我有这个python代码，可以搜索ebay来返回搜索字符串的结果。这些代码可以正确执行，并且可以根据需要返回结果，但是仅当我使用 print（）函数时才可以。我使用json将结果解析到烧瓶页面，使用print（）仅打印到控制台，因此我使用return，但是它没有给出所有结果，它仅返回一项。
如何使代码返回所有结果并将其显示在烧瓶页面上？
我是python的新手，这是我的第一个项目。我之前曾问过这个问题，并将代码升级到现在的样子，我一直在互联网上寻找解决方案，但我还没有找到。有人请帮我提供一个代码，该代码将返回从搜索中获得的所有结果。

答案 0 :(得分：0)
您的python代码仅返回itemsFound列表中的第一项，因为这就是您要执行的操作：
for key in itemsFound:
return itemsFound[key]
...为什么不只返回整个列表？像这样
return itemsFound

我能够通过修改我的代码来解决该问题：
#!/usr/bin/env python
import os
import sys
import pprint
import locale
import time
import datetime
import ebaysdk
from ebaysdk.finding import Connection as finding
from ebaysdk.exception import ConnectionError
from bs4 import BeautifulSoup
from flask import Flask
from flask import request, render_template, jsonify
HTML_OUTPUT = """
<div class=\"col-lg-6\">
<div class=\"box wow fadeInLeft\">
<div class=\"icon\"><img src=\"%s\" alt=\"Item Image\"></div>
<h4 class=\"title\">%s</h4>
<ul>
<li>Price: $ %s</li>
<li>Seller: %s</li>
<li>Condition: %s</li>
<li>Listing Type: %s</li>
</ul>

# Instantiate our Flask class.
app = Flask(__name__)
app.config['TEMPLATES_AUTO_RELOAD'] = True
# Decide which URL will trigger everything...
@app.route('/')
def ebay_serve_page():
empty_folder()
return render_template("index.html")
def empty_folder():
folder = 'static'
for the_file in os.listdir(folder):
file_path = os.path.join(folder, the_file)
try:
if os.path.isfile(file_path):
os.unlink(file_path)
#elif os.path.isdir(file_path): shutil.rmtree(file_path)
except Exception as e:
print(e)
# Grab search string entered by user...
@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')
items = soup.find_all('item')
# This will be returned
items_found = []
for item in items:
pic = item.PictureURL
title = item.title.string.strip()
price = float(item.currentprice.string)
url = item.viewitemurl.string.lower()
seller = item.sellerusername.text
listingtype = item.listingtype.string
condition = item.conditiondisplayname.string
print ('____________________________________________________________')
# Adding the item found in the collection
items_found.append(HTML_OUTPUT % (pic,
title,
price,
seller,
condition,
listingtype,
url))
f = open("static/"+search+".html", 'w+')
for item in items_found:
f.write("%s" % item)
f.close()
return "1"
except ConnectionError as e:
return jsonify(e)
if __name__ == '__main__':
app.run(debug = True)
然后我将ajax调用修改为此：
$(document).ready(function() {
$(".button").click(function() {
var search = $(".search").val().trim();
var file = search + ".html";
if (search) {
$.ajax({
type: 'POST',
url: "{{url_for('ebay_page_post')}}",
data: JSON.stringify({ 'search': search }),
contentType: 'application/json;charset=UTF-8',
dataType: "json",
success:function(data) {
if (data == "1") {
$.ajax({
url:"/static/"+file,
dataType:'html',
success: function(items){
$('#returned').html(items);
}
});
} else {
$("#returned").html(data);
}
}
});
}
});
});
