Shopify API - 响应代码 = 429。响应消息 = 请求过多

Question

我正在使用带有 Rails 的 Shopify API。但我收到一个错误。 我不知道为什么会出现这个错误。

ActiveResource::ClientError: Failed.  Response code = 429.  Response message = Too Many Requests.

我已遵循本教程：https://help.shopify.com/api/getting-started/api-call-limit。这是我的代码：

cycle = 0.5

product_count = ShopifyAPI::Product.count
nb_pages      = (product_count / 250.0).ceil

start_time = Time.now
1.upto(nb_pages) do |page|
    unless page == 1
        stop_time = Time.now
        processing_duration = stop_time - start_time
        wait_time = (cycle - processing_duration).ceil
        sleep wait_time if wait_time > 0
        start_time = Time.now
    end


    if product_list == 'all'
        products = ShopifyAPI::Product.find( :all, :params => { :limit => 250, :page => page } )
    elsif product_list.include? 'category'
        product_list.slice! "category"
        products = ShopifyAPI::Product.where(:collection_id => product_list, :limit => 250, :page => page )
    else
        products = ShopifyAPI::Product.find(:all, params: {ids: product_list})
    end

    products.each do |product|
        variants = Array.new
        metafields = Array.new
        product.variants.each do |variant|
            variants << variant
            metafields << product.metafields
            if variant.title.include? "+"
                next
            end
            quantity.each_with_index  do |q, i|

                unless customer_tag.to_s.strip.empty?
                    variants << {
                                    "title"=>"c #{variant.title} #{q}+",

                else
                    variants << {

                end

            end

        end

为什么会显示 Shopify API 限制错误？按照他们的教程，我只进行了 1 个 API 调用。请任何想法..

Answer 1

Shopify 遵循漏桶算法，这意味着它允许不频繁的调用突发。但是您需要平均 0.5 秒/呼叫。这些是对应于脚本中不同 API 调用的方法：

1. ShopifyAPI::Product.find
2. product.metafields
3. product.save

使用您上面编写的时序管理器仅管理第一个调用。接下来的两个电话也需要参与其中。
