Question

我想知道什么样的编程语言可以帮助我“自动阅读”网站？例如，我希望能够用代码编写：使用此密码登录以进行堆栈溢出，如果此页面有任何更改，请发送邮件给我......

感谢阅读！

PS：我知道一些html和C ++

好的，语言并不重要。如果使用Visual Basic for Windows构建应用程序，则可以自动执行浏览器对象，以完全按照导航时的操作执行操作。为此我通常使用Java，有库（我个人喜欢com.gargoylesoftware.htmlunit.WebClient）。

示例：

final WebClient webClient = new WebClient();
webClient.setThrowExceptionOnFailingStatusCode(false);
webClient.setThrowExceptionOnScriptError(false);
//webClient.setAppletEnabled(false);
//webClient.setJavaScriptEnabled(false);
// Get the first page
final HtmlPage page1 = webClient.getPage("http://fist.page/address.html");
    // Get the form that we are dealing with and within that form, 
        // find the submit button and the field that we want to change.
        final HtmlForm form = page1.getFormByName("form1");
        final HtmlSubmitInput button = form.getInputByName("send_button");
        final HtmlTextInput input1 = form.getInputByName("input1");
        final HtmlTextInput input2 = form.getInputByName("input2");

        // Change the value of the text field
        input1.setValueAttribute("I would type this");
        input2.setValueAttribute("I would type that");

        // Now submit the form by clicking the button and get back the second page.
        final HtmlPage page2 = button.click();

在c ++中，这似乎是你需要的：

void ProgressTest(void)
{
    // Set URL and call back function.
    WinHttpClient client(L"http://www.codeproject.com/", ProgressProc);
    client.SendHttpRequest();
    wstring httpResponseHeader = client.GetResponseHeader();
    wstring httpResponseContent = client.GetResponseContent();
}

有一些C ++背景，学习Python会很快，所以我建议你试试MechanicalSoup，这是一个允许你自动化web动作的Python库。它基于已经未维护的 Mechanize

使用哪种编程语言与网站进行交互？
