由於Shopify的默認產品導入器（通過CSV）速度非常慢，我正在使用多線程技術爲使用API的Shopify商店添加約24000種產品。該API有一個每秒2個的call limit。使用4個線程的呼叫在限制範圍內。爲什麼這些線程停止工作？
但過了一段時間所有線程停止工作，除了一個。我沒有收到任何錯誤消息，代碼仍在運行，但不打印任何產品信息。我似乎無法弄清楚發生了什麼問題。
下面是我使用的代碼：
require 'shopify_api'
require 'open-uri'
require 'json'
require 'base64'
begin_time = Time.now
my_threads = []
shop_url = "https://<API_KEY>:<PASSWORD>@<SHOPNAME>.myshopify.com/admin"
ShopifyAPI::Base.site = shop_url
raw_product_data = JSON.parse(open('<REDACTED>') {|f| f.read }.force_encoding('UTF-8'))
# Split raw product data
one, two, three, four = raw_product_data.each_slice((raw_product_data.size/4.0).round).to_a
def category_to_tag(input)
<REDACTED>
end
def bazookah(array, number)
array.each do |item|
single_product_begin_time = Time.now
# Store item data in variables
vendor = item['brand'].nil? ? 'Overige' : item['brand']
title = item['description']
item_size = item['salesUnitSize']
body = "#{vendor} - #{title} - #{item_size}"
type = item['category'].nil? ? 'Overige' : item['category']
tags = category_to_tag(item['category']) unless item['category'].nil?
variant_sku = item['itemId']
variant_price = item['basePrice']['price']
if !item['images'].nil? && !item['images'][2].nil?
image_src = item['images'][2]['url']
end
image_time_begin = Time.now
image = Base64.encode64(open(image_src) { |io| io.read }) unless image_src.nil?
image_time_end = Time.now
total_image_time = image_time_end - image_time_begin
# Create new product
new_product = ShopifyAPI::Product.new
new_product.title = title
new_product.body_html = body
new_product.product_type = type
new_product.vendor = vendor
new_product.tags = item['category'].nil? ? 'Overige' : tags
new_product.variants = [ <REDACTED> ]
new_product.images = [ <REDACTED> ]
new_product.save
creation_time = Time.now - single_product_begin_time
puts "#{number}: #{variant_sku} - P: #{creation_time.round(2)} - I: #{image_src.nil? ? 'No image' : total_image_time.round(3)}"
end
end
puts '====================================================================================='
puts "#{raw_product_data.size} products loaded. Starting import at #{begin_time}..."
puts '-------------------------------------------------------------------------------------'
my_threads << Thread.new { bazookah(one, 'one') }
my_threads << Thread.new { bazookah(two, 'two') }
my_threads << Thread.new { bazookah(three, 'three') }
my_threads << Thread.new { bazookah(four, 'four') }
my_threads.each { |thr| thr.join }
puts '-------------------------------------------------------------------------------------'
puts "Done. It took #{Time.now - begin_time} minutes."
puts '====================================================================================='
我可以嘗試解決這個問題？
