我正在使用java中的Google Drive API。我的代码中有孩子的文件夹ID,但我想要孩子的文件夹名称。我应用所有方法来获取儿童的文件夹名称,但我没有得到
Drive.Children.List FolderID = service.children().list(child.getId());
从这段代码我得到的文件夹ID就像0B3-sXIe4DGz1c3RhcnRlcl9。
Drive.Children.List Foldername = service.children().list(child.getId().getClass().getName());
在此代码中,它返回{folderId = java.lang.String}
如何获取文件夹的名称?
答案 0 :(得分:0)
在Google云端硬盘文件夹中是文件。您有使用Files.get的文件夹ID来返回包含该文件夹标题的FileResource。
的文档中删除了代码import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpResponse;
import com.google.api.services.drive.Drive;
import com.google.api.services.drive.model.File;
import java.io.IOException;
import java.io.InputStream;
// ...
public class MyClass {
// ...
/**
* Print a file's metadata.
*
* @param service Drive API service instance.
* @param fileId ID of the file to print metadata for.
*/
private static void printFile(Drive service, String fileId) {
try {
File file = service.files().get(fileId).execute();
System.out.println("Title: " + file.getTitle());
System.out.println("Description: " + file.getDescription());
System.out.println("MIME type: " + file.getMimeType());
} catch (IOException e) {
System.out.println("An error occured: " + e);
}
}
/**
* Download a file's content.
*
* @param service Drive API service instance.
* @param file Drive File instance.
* @return InputStream containing the file's content if successful,
* {@code null} otherwise.
*/
private static InputStream downloadFile(Drive service, File file) {
if (file.getDownloadUrl() != null && file.getDownloadUrl().length() > 0) {
try {
HttpResponse resp =
service.getRequestFactory().buildGetRequest(new GenericUrl(file.getDownloadUrl()))
.execute();
return resp.getContent();
} catch (IOException e) {
// An error occurred.
e.printStackTrace();
return null;
}
} else {
// The file doesn't have any content stored on Drive.
return null;
}
}
