Question

背景：

我每周在线检查我的成绩以便上学。然后我使用print-screen和ms paint来保存我的成绩的网站图像。（我知道这非常耗时且效率低，但我的计算机与我的打印机存在连接问题，并且无法识别任何PDF制造商）

可能的解决方案：

自动编写一些程序或其他内容：

打开浏览器

访问网站

登录

打开每个主题

创建一个图像（idc用于执行此操作的过程）

谢谢E'rybody

Answer 1

不要使用浏览器。以perl或类似的方式发送Http请求。

您只需解析HTML而不是抓取屏幕截图。

或者要求学校通过电子邮件或 bloddy 纸张提供您的成绩？

Answer 2

我个人会从命令行使用curl然后解析你得到的html：

curl http://website.com/grades

但是，如果你需要通过网络浏览器（他们可能有一些时髦的javascript），那么有一个名为selenium的框架可能是可用的：http://seleniumhq.org/

它通常用于测试，但可用于您的场景。它也有许多不同语言的客户。

Answer 3

您可以在java.awt中使用Robot类编写一个简单的java程序。这很简单。您可以自动化所有内容，因为计算机前面有人。可能需要一点努力。但相信我，你可以让它完美地解决你的问题。

如果您对此有任何疑问，请随时与我联系。我会帮忙的。

Answer 4

试试这个。这有点长。但它会告诉你Robot类的功能。您可以通过在'go（）'方法中调用它们来尝试所有方法。如果您稍微耐心一点，那么您将能够像操作人员一样自动执行鼠标和键盘操作。

本课程是为更高级的功能而编写的（当然，只是为了好玩）。所以，你不需要那些先进的方法。你可以通过他们的名字来理解。

请注意，我发布了由我撰写的原始课程（sumudu lansakara或Codenamed_SC）。我没有根据您的要求对其进行修改或使其看起来很简单。你可以自己做那个部分。（但我认为完整代码现在或以后都会有所帮助。）
