前言

先查看rebots协议，不让爬的数据咱不动。
以马来西亚站点为例：https://www.lazada.com.my/robots.txt

处理逻辑

如果从首页进入，然后查看请求商品数据，请求参数中都有appKey和sign，也就是sign不破解出来是万万拿不到数据的，而且如果sign错误了一次，再请求的时候jsv参数就会跟着变，造成很难找到固定的规律。但是，首页的分类点击进入的页面是不需要sign的，这个就方便太多了。

商品分类

商品列表页使用这个（或者直接使用首页也可以）：https://pages.lazada.com.my/wow/i/my/LandingPage/lp-collection-detail-new，左上角打开就是全部分类，get请求直接进行Document解析即可。

商品列表

点击商品分类，进入的页面是分页的商品列表信息，完全没有加密逻辑，直接使用请求参数访问即可。参数也只有一个页码，比如：https://www.lazada.com.my/mobile-phone-cases/?ajax=true&page=1

其他站点

新加坡：https://www.lazada.sg/
马来西亚：https://pages.lazada.com.my/
印度尼西亚：https://www.lazada.co.id/
菲律宾：https://www.lazada.com.ph/
泰国：https://www.lazada.co.th/
越南：https://www.lazada.vn/

Java测试代码

其实就一个get请求，也没有什么好写的，但是因为篇幅不够csdn总是给提示，让增加一些内容，就把这个代码写上吧，然后也进行一下数据解析。以上面给出的链接为例：

		String url = "https://www.lazada.com.my/mobile-phone-cases/?ajax=true&page=1";String result = Jsoup.connect(url).method(Method.GET).ignoreContentType(true).timeout(30000).execute().body();JSONObject jsonResult = JSON.parseObject(result);JSONArray array = jsonResult.getJSONObject("mods").getJSONArray("listItems");for(int i = 0; i < array.size(); i++) {System.out.print("商品名称：" + array.getJSONObject(i).getString("name"));System.out.println("显示的价格：" + array.getJSONObject(i).getString("priceShow"));}
