Java 使用管理访问权限导出/下载演示文稿和电子表格模拟其他域用户

我需要导出/下载其他域用户的所有文件。我使用客户端登录管理帐户来查看域用户的所有文件。但是，只有文档可以导出/下载，其他文档无法导出/下载

那么其他的下载url格式（文件、pdf、演示文稿和电子表格）是什么

我的文档下载url是

https://docs.google.com/feeds/download/documents/Export?xoauth_requestor=admin@domain.com&docId=<id>&exportFormat=doc

---

}

不要手动构建下载链接，而是使用条目的内容链接，如文档中所述：

---

如果不手动构建下载链接，我将得到异常“无验证头信息”。但是，文件类型“文件”和“文件”可以正常下载。

public class AuthExample {

private static DocsService docService = new DocsService("Auth Example");

public static void main(String[] args)
    throws Exception
{
    String adminUser = admin;
    String adminPassword = adminpasswd;
    String impersonatedUser = "user@domain.com";

    docService.setUserCredentials(adminUser, adminPassword);
    URL url = new URL( "https://docs.google.com/feeds/" + impersonatedUser + "/private/full");
    DocumentListFeed feed = docService.getFeed(url, DocumentListFeed.class);
    for (DocumentListEntry entry : feed.getEntries()) {


String title = entry.getTitle().getPlainText();
System.out.println( title );

String type = entry.getType();
if ( type.equals("document") )
{
    String encodedAdminUser = URLEncoder.encode(adminUser);
    String resourceId = entry.getResourceId();
    String resourceIdNoPrefix = resourceId.substring( resourceId.indexOf(':')+1 );

    String downloadUrl =
        "https://docs.google.com/feeds/download/documents/Export" +
        "?xoauth_requestor=" + encodedAdminUser +
        "&docId=" + resourceIdNoPrefix +
        "&exportFormat=doc";

    downloadFile( downloadUrl, title + ".doc" );
}

    }
}



// Method pasted directly from Google documentation
public static void downloadFile(String exportUrl, String filepath)
    throws IOException, MalformedURLException, ServiceException
{
System.out.println("Exporting document from: " + exportUrl);
MediaContent mc = new MediaContent();
mc.setUri(exportUrl);
MediaSource ms = docService.getMedia(mc);

InputStream inStream = null;
FileOutputStream outStream = null;

try {
        inStream = ms.getInputStream();
    outStream = new FileOutputStream(filepath);
                    int c;
    while ((c = inStream.read()) != -1) {
    outStream.write(c);
    }
} finally {
    if (inStream != null) {
        inStream.close();
    }
    if (outStream != null) {
    outStream.flush();
        outStream.close();
    }
}
}
