我在谷歌文档中存储了一个文本文件，这是一个共享的公共文件。我正在尝试通过 url 读取该文件的内容。但它没有显示内容。我在这里附上我的代码。请建议我应该在哪里更改我的代码以读取文件的内容。当我在任何网络浏览器的地址栏中写入内容时，我在 URL 中给出的地址正在显示内容。我实际上不知道在哪里更正代码。我在代码末尾添加了输出

package FileContent;

import java.awt.*; 
import java.net.*; 
import java.io.*; 

public class FileContent extends Frame {
    public static void main(String[] args) {

        BufferedReader br = null;
        TextArea FileText = new TextArea("  Content of the File \'temp1.txt\' :", 11, 24, TextArea.SCROLLBARS_NONE);

        try {
            // here is the url
            URL url = new URL("https://docs.google.com/file/d/0B9MOgXFCss2iSWpicmVKSW9OOWM/edit");

            InputStream is = url.openStream();
            br = new BufferedReader(new InputStreamReader(is));
        } catch (MalformedURLException e) {
            System.out.println("Bad URL");
        } catch (IOException e) {
            System.out.println("IO Error : " + e.getMessage());
        }

        FileText.setBackground(Color.cyan);
        FileText.append(String.valueOf('\n'));

        Frame f = new Frame("File Content");
        f.setSize(200, 200);
        f.add(FileText);
        f.setVisible(true);

        try {
            String s;
            boolean eof = false;
            s = br.readLine();

            while (!eof) {
                FileText.append(s + String.valueOf('\n'));
                try {
                    s = br.readLine();
                    if (s == null) {
                        eof = true;
                        br.close();
                    }
                } catch (EOFException eo) {
                    eof = true;
                } catch (IOException e) {
                    System.out.println("IO Error : " + e.getMessage());
                }
            }

        } catch (IOException e) {
            System.out.println("IO Error : " + e.getMessage());
        }
    }    
}

您所采取的仅向 google doc 发出 http 请求的方法可能会导致您被重定向到登录页面或其他内容。如果您能够访问该文档，那么您将不得不提出其 HTML 结构的解析策略，该策略可能会发生变化，并且实际上不会关心事先通知您。

我建议您查看谷歌开发者网站并查看他们可用的不同 api。看起来他们有有用的 REST api，看起来他们也可能有一个纯 Java 客户端。我会查看这个链接：https ://developers.google.com/drive/quickstart-java
