以编程方式编辑Google电子表格

我有一个用户输入的程序，但现在我希望每次用户提交表单时都可以通过编辑Google电子表格来保存输入。 基本上，Google电子表格会不断更新。

任何人都可以提供一个关于我如何能够实现这一目标的教程吗？ 我使用Eclipse编写Java，我需要哪些插件？

我已经尝试使用Google Spreadsheets API中提供的一些示例代码（ 添加列表行部分），但我似乎无法让它工作。

import com.google.gdata.client.spreadsheet.*; import com.google.gdata.data.spreadsheet.*; import com.google.gdata.util.*; import java.io.IOException; import java.net.*; import java.util.*; public class MySpreadsheetIntegration { public static void main(String[] args) throws AuthenticationException, MalformedURLException, IOException, ServiceException { SpreadsheetService service = new SpreadsheetService("MySpreadsheetIntegration-v1"); // TODO: Authorize the service object for a specific user (see other sections) // Define the URL to request. This should never change. URL SPREADSHEET_FEED_URL = new URL( "https://docs.google.com/spreadsheets/d/1OcDp1IZ4iuvyhndtrZ3OOMHZNSEt7XTaaTrhEkNPnN4/edit#gid=0"); // Make a request to the API and get all spreadsheets. SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class); List spreadsheets = feed.getEntries(); if (spreadsheets.size() == 0) { // TODO: There were no spreadsheets, act accordingly. } // TODO: Choose a spreadsheet more intelligently based on your // app's needs. SpreadsheetEntry spreadsheet = spreadsheets.get(0); System.out.println(spreadsheet.getTitle().getPlainText()); // Get the first worksheet of the first spreadsheet. // TODO: Choose a worksheet more intelligently based on your // app's needs. WorksheetFeed worksheetFeed = service.getFeed( spreadsheet.getWorksheetFeedUrl(), WorksheetFeed.class); List worksheets = worksheetFeed.getEntries(); WorksheetEntry worksheet = worksheets.get(0); // Fetch the list feed of the worksheet. URL listFeedUrl = worksheet.getListFeedUrl(); ListFeed listFeed = service.getFeed(listFeedUrl, ListFeed.class); // Create a local representation of the new row. ListEntry row = new ListEntry(); row.getCustomElements().setValueLocal("firstname", "Joe"); row.getCustomElements().setValueLocal("lastname", "Smith"); row.getCustomElements().setValueLocal("age", "26"); row.getCustomElements().setValueLocal("height", "176"); // Send the new row to the API for insertion. row = service.insert(listFeedUrl, row); } } 

Answer 1

似乎很晚，但肯定会帮助别人！ 问题在于您的SPREADSHEET_FEED_URL和SpreadSheetService实例的身份validation，因为官方的SpreadSheets Api尚未对此进行详细解释。您需要获取身份validation令牌并将其设置在SpreadSheetService Instance上，如下所示：

  private void getAuthenticationToken(Activity activity, String accountName){ //Scopes used to get access to google docs and spreadsheets present in the drive String SCOPE1 = "https://spreadsheets.google.com/feeds"; String SCOPE2 = "https://docs.google.com/feeds"; String scope = "oauth2:" + SCOPE1 + " " + SCOPE2; String authenticationToken = null; try { accessToken= GoogleAuthUtil.getToken(activity, accountName, scope); } catch (UserRecoverableAuthException exception){ //For first time, user has to give this permission explicitly Intent recoveryIntent = exception.getIntent(); startActivityForResult(recoveryIntent, RECOVERY_REQUEST_CODE); }catch (IOException e) { e.printStackTrace(); } catch (GoogleAuthException e) { e.printStackTrace(); } } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == RECOVERY_REQUEST_CODE){ if(resultCode == RESULT_OK){ if(data != null){ String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME); if (accountName != null && !accountName.equals("")){ //To be called only for the first time after the permission is given getAuthenticationToken(activity, accountName); } }else { Utility.showSnackBar(linearLayout, Constants.INTENT_DATA_NULL); } } } } 

最后在代码下方获取电子邮件帐户中的所有电子表格：

 public class MySpreadsheetIntegration { public void getSpreadSheetEntries() throws AuthenticationException, MalformedURLException, IOException, ServiceException { SpreadsheetService service = new SpreadsheetService("MySpreadsheetIntegration-v1"); service = new SpreadsheetService(applicationName); service .setProtocolVersion(SpreadsheetService.Versions.V3); service .setAuthSubToken(accessToken); // Define the URL to request. This should never change. URL SPREADSHEET_FEED_URL = new URL( "https://spreadsheets.google.com/feeds/spreadsheets/private/full"); // Make a request to the API and get all spreadsheets. SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class); List spreadsheets = feed.getEntries(); // Iterate through all of the spreadsheets returned for (SpreadsheetEntry spreadsheet : spreadsheets) { // Print the title of this spreadsheet to the screen System.out.println(spreadsheet.getTitle().getPlainText()); } } }
