Question

如何使用java将文件上传到谷歌驱动器。我的java代码是。

HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(
    httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE))
    .setAccessType("online")
    .setApprovalPrompt("auto").build();

String url = flow.newAuthorizationUrl().setRedirectUri(REDIRECT_URI).build();
System.out.println("Please open the following URL in your browser then type the authorization code:");
System.out.println("  " + url);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String code = br.readLine();

GoogleTokenResponse response = flow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();
GoogleCredential credential = new GoogleCredential().setFromTokenResponse(response);

//Create a new authorized API client
Drive service = new Drive.Builder(httpTransport, jsonFactory, credential).build();

//Insert a file  
File body = new File();
body.setTitle("My document");
body.setDescription("A test document");
body.setMimeType("text/plain");

java.io.File fileContent = new java.io.File("document.txt");
FileContent mediaContent = new FileContent("text/plain", fileContent);

File file = service.files().insert(body, mediaContent).execute();
System.out.println("File ID: " + file.getId());
}}

所以在那个文件对象中（ java.io.File fileContent = new java.io.File（＆＃34; document.txt＆＃34;）;）询问完整的文件路径。但是文件上传我们只能得到文件名而不是路径。如何解决问题。请帮助我。
