Question

我正在使用此代码：

public static void main(String[] args) throws IOException {
    String EngLink;
    URL EngUrl;
    URLConnection EngCon;
    String cookiesHeader;
    InputStream EngIs;
    BufferedReader EngBr;
    String line;
    String EngPageHtml="";

    EngLink="https://www.zomato.com/";
    EngUrl = new URL(EngLink);
    EngCon = (HttpURLConnection) EngUrl.openConnection();
    EngCon.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB;     rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 (.NET CLR 3.5.30729)");

    EngIs = EngCon.getInputStream();
    EngBr = new BufferedReader(new InputStreamReader(EngIs,"UTF-8"));

    while ((line = EngBr.readLine()) != null) {
        EngPageHtml = EngPageHtml + "\n" + line;
    }

    System.out.println(EngPageHtml);        
    }

我想要做的是获取网站的原始html。但是，当我运行代码时，我收到此错误：

Exception in thread "main" java.net.SocketTimeoutException: Read timed out

我正在使用此代码成功获取多个其他网站的HTML，但这个特定的网站不起作用。

可能是什么问题，我该如何解决这个问题？

编辑：在Firefox中加载网站，从那里获取cookie并将其传递到：

EngCon.setRequestProperty("Cookie",cookie);

使页面加载，但这不好，因为它不能一次又一次地使用。

Answer 1

这是通过添加另一个请求属性来解决的：

EngCon.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

不需要其他任何东西

无法使用URLConnection连接到特定网站，读取超时
