Question

我面临以下例外：

Exception in thread "main" java.io.IOException: Server returned HTTP response code: 403 for URL: https://xyz.abc.com

我已尝试过很多论坛中提到的所有可能的解决方案，但仍然无法连接。

   try{
    URLConnection openConnection = new URL("https://xyz.abc.com").openConnection();
    openConnection.addRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:25.0) Gecko/20100101 Firefox/25.0");
    InputStream is = openConnection.getInputStream();

    InputSource source = new InputSource(is);

} catch (Exception e){
    System.out.println("---ee---" + e);
    throw e;
}

另一项试验：

 URL obj = new URL("https://xyz.abc.com");
                HttpURLConnection connection = ((HttpURLConnection) obj.openConnection());
                connection.addRequestProperty("User-Agent", "Mozilla/4.0");
                System.out.println("--connection.getResponseCode() --" + connection.getResponseCode() );//403

任何建议都会有所帮助。我是否需要安装一些证书（不确定）。

            else {

                System.err.println(e);
            }
    }

输出：

你可以尝试下面的代码：

openConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");
