var node = document.DocumentNode.SelectNodes(
    "//span[@class='short_text' and @id='result_box']");

if (node != null)

推荐答案

这是个坏主意.正如评论员指出的那样，Google提供了程序化界面作为付费服务. Google肯定具有适当的安全功能，试图阻止您所做的一切，这就是为什么它不起作用.也许您可以使它以某种方式工作，但是即使那样，您也始终有可能会提高Google的安全性并再次阻止您的脚本.此外，您几乎肯定会违反Google的使用条款.

This is a bad idea. As commenters have pointed out, Google offers a programmatic interface as a paid service. Google surely has security features in place to try to block exactly what you are doing, and that is why it isn't working. Perhaps you could get it working somehow, but even then you would always be in danger of Google improving its security and your script being blocked again. In addition, you are almost certainly breaking the Google terms of use.
