【中文标题】如何获得所有亚马逊类别的产品【英文标题】：how to get all amazon category products 【发布时间】：2011-12-08 21:34:06 【问题描述】：如何从现有类别中获取所有亚马逊产品？
使用 API，我可以浏览 10 个页面，并为每个页面获取 10 个产品。
该类别有 502348 个产品，我想全部获取。
这是我的代码：
Amazon Product Advertising API <?php ?>
$params = array(
'Operation' => 'ItemSearch',
'SearchIndex'=>'Electronics',
//'BrowseNode'=>'281052',
'ResponseGroup'=>'small',
//'MerchantId' => 'All',
//'Condition'=>'New',
'ItemPage'=>'1471',
【问题讨论】：
我不认为亚马逊想要一次向您发送 500,000 种产品的信息。 那么有什么系统的方法可以在几次内获得它吗？事情是以前亚马逊让你得到 400 页，现在它只给你 10 页。 这太可悲了，我面临着同样的问题。你有没有找到解决办法？他们有数据提要，但我怀疑他们会在看到服务之前将其提供给任何人。但我需要它来建立我的服务。鸡蛋/鸡delimma 你有没有找到一个好的解决方案？我遇到了同样的问题。 @Yan 你找到解决这个挑战的方法了吗？ 【参考方案1】：也许您应该尝试在查询中添加两个额外的搜索参数 - MinimumPrice 和 MaximumPrice - 当然要结合 关键字 .然后，每当您的搜索条件超过 10 页时，您应该更正您的最低/混合价格值。
这就是我能够“避免”亚马逊设定的不合理限制的方式。
【讨论】：
您好，您能否提供工作代码以将所有产品归入一个类别？【参考方案2】：使用来自Amazon Robots.txt 的站点地图：
http://www.amazon.com/sitemaps.US_detail_page_sitemap_desktop_index.xml.gz
【讨论】：
【参考方案3】：您看到了亚马逊施加的新限制。来自产品广告 API home page：
ItemPage 参数将限制为 ItemSearch 结果最多 10 页
【讨论】：
是的，我知道，我在问虽然它限制了 10 页，但我怎样才能系统地获得所有这些产品，它必须是一种方式.. @Yan imm 的回应是一种方法。 我的意思是用户 imm 提供的其他回复是您问题的一种可能解决方案。 @JonathanSpooner 你能帮我如何获得更多产品吗？ imm是什么？【参考方案4】：使用循环，从每个页面拉出所有产品，直到没有更多页面。
【讨论】：
但我做不到，我只需要 10 页。【参考方案5】：<?php
