Ruby and Ebay: Get list prices
Oct 3, 2010 - 2 minutesI’ll eventually be turning my ruby ebay work into a gem, but for now here are little snippets:
Please note that this code automagically takes care of things like 4x SOMETHING – it’ll take the current list price and divide by four, if you don’t want that functionality, remove the divider. You also need rest-open-uri and hpricot for gems.
To get a list of prices:
1def self.get_search_results(query)
2 # API request variables
3 endpoint = 'http://svcs.ebay.com/services/search/FindingService/v1'; # URL to call
4 version = '1.0.0'; # API version supported by your application
5 appid = 'YOUR APP ID'; # Replace with your own AppID
6 globalid = 'EBAY-US'; # Global ID of the eBay site you want to search (e.g., EBAY-DE)
7 safequery = URI.encode(query); # Make the query URL-friendly
8
9 # Construct the findItemsByKeywords HTTP GET call
10 apicall = "#{endpoint}?";
11 apicall += "OPERATION-NAME=findItemsByKeywords";
12 apicall += "&SERVICE-VERSION=#{version}";
13 apicall += "&SECURITY-APPNAME=#{appid}";
14 apicall += "&GLOBAL-ID=#{globalid}";
15 apicall += "&keywords=#{safequery}";
16 apicall += "&paginationInput.entriesPerPage=25";
17
18 res = ""
19
20 open( apicall ).each { |s| res << s }
21 prices = []
22
23
24 doc = Hpricot.parse(res)
25 (doc/:item).each do |x|
26
27 divider = 1
28 get_count = (x/:title).inner_html.scan(/[0-9]/).first
29 p "#{(x/:title).inner_html}"
30 if !get_count.nil?
31 divider = get_count.to_i
32 end
33 prices << (x/:sellingstatus/:currentprice).inner_html.to_f/divider
34 end
35
36 prices
37end
