Google drive api服务帐户使用java查看上传到Google drive的文件

Question

我已经创建了代码，使用java中的服务帐户将文件插入到google drive。文件已上传至google drive，但我无法使用网络浏览器查看。当我使用代码检查文件时，我可以检索上传的文件。我的问题是，如何使用java中的google services帐户将文件上传到google drive，以便通过网络浏览器查看

请在下面找到示例代码。

      public class PlusServiceAccountSample {


          private static final String APPLICATION_NAME = "";

          /** E-mail address of the service account. */
          private static final String SERVICE_ACCOUNT_EMAIL = "[e-mail]" ;

          /** Global instance of the HTTP transport. */
          private static HttpTransport httpTransport;

          /** Global instance of the JSON factory. */
          private static final JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();


          public static void main(String[] args) {
            try {
              try {
                httpTransport = GoogleNetHttpTransport.newTrustedTransport();
                // check for valid setup
                if (SERVICE_ACCOUNT_EMAIL.startsWith("Enter ")) {
                  System.err.println(SERVICE_ACCOUNT_EMAIL);
                  System.exit(1);
                }
                String p12Content = Files.readFirstLine(new File("XXXXX-privatekey.p12"), Charset.defaultCharset());
                if (p12Content.startsWith("Please")) {
                  System.err.println(p12Content);
                  System.exit(1);
                }
                // service account credential (uncomment setServiceAccountUser for domain-wide delegation)
                GoogleCredential credential = new GoogleCredential.Builder().setTransport(httpTransport)
                    .setJsonFactory(JSON_FACTORY)
                    .setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
                    .setServiceAccountScopes(Collections.singleton(DriveScopes.DRIVE))
                    .setServiceAccountPrivateKeyFromP12File(new File("XXXXXXXX-privatekey.p12"))

                    .build();


                Drive service = new Drive.Builder(httpTransport, JSON_FACTORY,credential).build();

                com.google.api.services.drive.model.File  file = new com.google.api.services.drive.model.File();
                file.setTitle("testdd");
                file.setMimeType("application/vnd.google-apps.spreadsheet");
                Drive.Files.Insert insert = null;
                try {
                    insert = service.files().insert(file);
                    file = insert.execute();


                } catch (Exception e) {
                    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
                }

                com.google.api.services.drive.model.File uploadedDoc = service.files().get("1ZJnkgFXAiUNSBeq3DmhHGqXn7-v37vLg1UsRekRQNjU").execute();

                System.out.println("Title: " + uploadedDoc.getTitle());




                return;
              } catch (IOException e) {
                System.err.println(e.getMessage());
              }
            } catch (Throwable t) {
              t.printStackTrace();
            }
            System.exit(1);
          }

Answer 1

< li >转到您的Google Drive。创建一些文件夹，并打开“共享设置”。 < li >将您的服务电子邮件添加到允许用户列表，并允许其编辑该文件夹的内容。 < li >记住文件夹id并在上传文件时使用此文件夹ID。 < li >它将被上传到您的个人google drive帐户中。

Answer 2

如果您为文件设置权限，您可以在常规gmail帐户（“与我共享”部分）中看到它：

Permission newPermission = new Permission();
newPermission.setValue("...your regular [e-mail]");
newPermission.setType("user");
newPermission.setRole("reader");
service.permissions().insert(file.getId(), newPermission).execute();

您还可以使用唯一的url访问文件：

System.out.println("Title: " + uploadedDoc.getTitle()+ " "+ uploadedDoc.getAlternateLink());

类型和角色的可能值在Google Drive SDK文档中：https://developers.google.com/drive/v2/reference/permissions/insert
