如何在Mechanize和Nokogiri中单击链接? [英] How to click link in Mechanize and Nokogiri?

问题描述

我正在使用Mechanize抓取Google电子钱包中的订单数据.我正在捕获第一页中的所有数据，但是，我需要自动链接到后续页面以获取更多信息.

I'm using Mechanize to scrape Google Wallet for Order data. I am capturing all the data from the first page, however, I need to automatically link to subsequent pages to get more info.

#purchaseOrderPager-pagerNextButton将移至下一页，因此我可以提取更多记录以进行捕获.元素看起来像这样.我需要单击它才能继续.

The #purchaseOrderPager-pagerNextButton will move to the next page so I can pick up more records to capture. The element looks like this. I need to click on it to keep going.

<a id="purchaseOrderPager-pagerNextButton" class="kd-button small right"
 href="purchaseorderlist?startTime=0&amp;...
;currentPageStart=1&amp;currentPageEnd=25&amp;inputFullText=">
<img src="https://www.gstatic.com/mc3/purchaseorder/page-right.png"></a>

但是，当我尝试以下操作时，我得到一个错误:

However, when I try the following I get an error:

  next_page = @orders_page.search("#purchaseOrderPager-pagerNextButton")
  next_page.click

错误:

undefined method `click' for #<Nokogiri::XML::NodeSet:0x007f9019095550> (NoMethodError)

推荐答案

click 是 Mechanize类的方法.

click is a method of Mechanize class.

请尝试填写以下表格.

next_page = @orders_page.at("#purchaseOrderPager-pagerNextButton")
mechanize_instance.click(next_page)

注意，将mechanize_instance替换为实际变量.

NOTE Replace mechanize_instance with actual variable.
