如果我问正确的问题，我不能100％肯定。 我去的网站使用了一个我需要访问的JSON字符串。我可以在Firefox＆＃34;网络选项卡＆＃34;中找到JSON字符串的位置。通过单击F12并选择＆＃34; Network＆＃34;标签。
所以我想我可以通过进入临时的互联网文件来访问该文件，但没有骰子。 我也认为watir可以通过自己访问临时的互联网文件，但我能找到的就是这个。
require 'watir-webdriver'
$browser = Watir::Browser.new
$browser.methods

除了我需要访问的json临时文件外，有一种方法可以访问其他所有内容。 我还没有看到任何关于此的文档，因为我不确定我是否提出了正确的问题。
更新： 该方法是200 POST，扩展类型为json。
