使用以下代码,我正在尝试从我们电话服务提供商的Web应用程序中抓取通话记录以将信息输入到我的Ruby on Rails应用程序中。
以下是生成该文本的代码:
desc "Import incoming calls"
task :fetch_incomingcalls => :environment do
# Logs into manage.phoneprovider.co.uk and retrieved list of incoming calls.
require 'rubygems'
require 'mechanize'
require 'logger'
# Create a new mechanize object
agent = Mechanize.new { |a| a.log = Logger.new(STDERR) }
# Load the Phone Provider website
page = agent.get("https://manage.phoneprovider.co.uk/login")
# Select the first form
form = agent.page.forms.first
form.username = 'username
form.password = 'password
# Submit the form
page = form.submit form.buttons.first
# Click on link called Call Logs
page = agent.page.link_with(:text => "Call Logs").click
# Click on link called Incoming Calls
page = agent.page.link_with(:text => "Incoming Calls").click
# Prints out table rows
# puts doc.css('table > tr')
# Print out the body as a test
# puts page.body
end
从最后五行可以看出,我已经测试了“puts page.body”成功工作,并且上面的代码也可以正常运行。它成功登录并导航到通话记录,然后是呼入电话。呼入电话表格如下:
| Timestamp | Source | Destination | Duration |
| 03 Jan 13:40 | 12345678 | 12345679 | 00:01:01 |
| 03 Jan 13:40 | 12345678 | 12345679 | 00:01:01 |
| 03 Jan 13:40 | 12345678 | 12345679 | 00:01:01 |
| 03 Jan 13:40 | 12345678 | 12345679 | 00:01:01 |
以下是生成该文本的代码:

<td>Cost</td>
<td class='centre'>Recording</td>

<tbody>
<tr class='o'>

我正在研究如何仅选择我想要的单元格(时间戳,来源,目的地和持续时间)并输出这些单元格。然后我可以担心将它们输出到数据库而不是在终端中。
我尝试使用Selector Gadget,但如果我选择多个,则只显示'td'或'tr:nth-child(6)td,tr:nth-child(2)td'。
任何帮助或指针将不胜感激!
