已经有一些人就此提出了问题,但我仍然无法解决我的问题。
所以,我做了gradle / java quickstart来打印Googledrive中最多10个文件的名称和ID。那很好,但我想写一个java脚本来上传我的驱动器上的文件,我在下面的java文件中插入了main函数。
public class DriveCommandLine {
/** Application name. */
private static final String APPLICATION_NAME =
"Drive API Java Quickstart";
/** Directory to store user credentials for this application. */
private static final java.io.File DATA_STORE_DIR = new java.io.File(
System.getProperty("user.home"), ".credentials/drive-java-quickstart");
/** Global instance of the {@link FileDataStoreFactory}. */
private static FileDataStoreFactory DATA_STORE_FACTORY;
/** Global instance of the JSON factory. */
private static final JsonFactory JSON_FACTORY =
JacksonFactory.getDefaultInstance();
/** Global instance of the HTTP transport. */
private static HttpTransport HTTP_TRANSPORT;
/** Global instance of the scopes required by this quickstart.
*
* If modifying these scopes, delete your previously saved credentials
* at ~/.credentials/drive-java-quickstart
*/
private static final List<String> SCOPES =
Arrays.asList(DriveScopes.DRIVE_METADATA_READONLY);
static {
try {
HTTP_TRANSPORT = GoogleNetHttpTransport.newTrustedTransport();
DATA_STORE_FACTORY = new FileDataStoreFactory(DATA_STORE_DIR);
} catch (Throwable t) {
t.printStackTrace();
System.exit(1);
}
}
/**
* Creates an authorized Credential object.
* @return an authorized Credential object.
* @throws IOException
*/
public static Credential authorize() throws IOException {
// Load client secrets.
InputStream in =
DriveCommandLine.class.getResourceAsStream("/client_secret.json");
GoogleClientSecrets clientSecrets =
GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
// Build flow and trigger user authorization request.
GoogleAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(DATA_STORE_FACTORY)
.setAccessType("offline")
.build();
Credential credential = new AuthorizationCodeInstalledApp(
flow, new LocalServerReceiver()).authorize("user");
System.out.println(
"Credentials saved to " + DATA_STORE_DIR.getAbsolutePath());
return credential;
}
/**
* Build and return an authorized Drive client service.
* @return an authorized Drive client service
* @throws IOException
*/
public static Drive getDriveService() throws IOException {
Credential credential = authorize();
return new Drive.Builder(
HTTP_TRANSPORT, JSON_FACTORY, credential)
.setApplicationName(APPLICATION_NAME)
.build();
}
public static void main(String[] args) throws IOException{
//Insert a file
Drive service = getDriveService();
File body = new File();
body.setDescription("A test document");
body.setMimeType("text/plain");
java.io.File fileContent = new java.io.File("D:\\MyFiles\\nkonstantinidis\\Study\\IntelliJ_Shortcuts.txt");
FileContent mediaContent = new FileContent("text/plain", fileContent);
File file = service.files().insert(body, mediaContent).execute();
System.out.println("file ID: " + file.getId());
}
}
我运行时收到如下错误消息
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code" : 403,
"errors" : [ {
"domain" : "global",

"reason" : "insufficientPermissions"
} ],

}

at DriveCommandLine.main(DriveCommandLine.java:114)
我创建了OAuth客户端ID并启用了Google驱动器,但这仍然是这样做的。
你能帮助我吗,或者甚至更好地指导谷歌驱动器上传文件的教程,我在Java中非常糟糕,所以请耐心等待。
提前致谢。

您必须将用于连接的SCOPE(Insufficient Permission消息)更改为适当的
private static final List<String> SCOPES = Arrays.asList(DriveScopes.DRIVE_METADATA_READONLY);
来自DriveScope.class:
/** View and manage the files in your Google Drive. */
public static final String DRIVE = "https://www.googleapis.com/auth/drive";
/** View and manage its own configuration data in your Google Drive. */
public static final String DRIVE_APPDATA = "https://www.googleapis.com/auth/drive.appdata";
/** View and manage Google Drive files and folders that you have opened or created with this app. */
public static final String DRIVE_FILE = "https://www.googleapis.com/auth/drive.file";
/** View and manage metadata of files in your Google Drive. */
public static final String DRIVE_METADATA = "https://www.googleapis.com/auth/drive.metadata";
/** View metadata for files in your Google Drive. */
public static final String DRIVE_METADATA_READONLY = "https://www.googleapis.com/auth/drive.metadata.readonly";
/** View the photos, videos and albums in your Google Photos. */
public static final String DRIVE_PHOTOS_READONLY = "https://www.googleapis.com/auth/drive.photos.readonly";
/** View the files in your Google Drive. */
public static final String DRIVE_READONLY = "https://www.googleapis.com/auth/drive.readonly";
/** Modify your Google Apps Script scripts' behavior. */
public static final String DRIVE_SCRIPTS = "https://www.googleapis.com/auth/drive.scripts";
请记住在更改SCOPE后删除已保存的凭据(由应用程序创建)
