我對Java很陌生,對Google Data API也是新手。我正嘗試在公開共享的電子表格中更改工作表的大小。我使用下面的代碼:Java Google Spreadsheet API:更新公共工作表'java.lang.UnsupportedOperationException:條目無法更新'
import com.google.gdata.client.authn.oauth.*;
import com.google.gdata.client.spreadsheet.*;
import com.google.gdata.data.*;
import com.google.gdata.data.batch.*;
import com.google.gdata.data.spreadsheet.*;
import com.google.gdata.util.*;
import java.io.IOException;
import java.net.*;
import java.util.*;
static void writeToGoogleSpreadsheet(String spreadsheetKey) throws IOException, ServiceException {
SpreadsheetService service = new SpreadsheetService("com.example");
String urlString = "https://spreadsheets.google.com/feeds/worksheets/" + spreadsheetKey + "/public/basic";
URL url = new URL(urlString);
try {
WorksheetFeed worksheetFeed = service.getFeed(url, WorksheetFeed.class);
List<WorksheetEntry> worksheets = worksheetFeed.getEntries();
WorksheetEntry worksheet = worksheets.get(0);
System.out.println(worksheet.getTitle().getPlainText());
System.out.println(worksheet.getCanEdit());
// Update the local representation of the worksheet.
worksheet.setTitle(new PlainTextConstruct("Updated Worksheet"));
worksheet.setColCount(40);
worksheet.setRowCount(40);
// Send the local representation of the worksheet to the API for
// modification.
worksheet.update();
} finally{}
}
控制檯顯示正確的工作表名稱和大小,所以我敢肯定,我訪問權工作。但是,worksheet.update()會引發以下異常:
Exception in thread "main" java.lang.UnsupportedOperationException: Entry cannot be updated
at com.google.gdata.data.BaseEntry.update(BaseEntry.java:635)
atcom.example.GoogleSpreadsheetCommunicator.writeToGoogleSpreadsheet(GoogleSpreadsheetCommunicator.java:119)
at com.example.Main.guildSim(Main.java:114)
at com.example.Main.main(Main.java:73)
有沒有人知道我在做什麼錯?
感謝您的閱讀和親切的問候,

這將解釋很多!謝謝!你有沒有關於這方面的未來參考文件?由於https://developers.google.com/google-apps/spreadsheets/#working_with_cell-based_feeds'注意:單元格Feed支持私人和公共的可見性,以及完整和基本投影。「表明可以編輯公共流。 – user3613853
np!我從經驗中瞭解到這一點,面臨同樣的問題,所以我查看了BaseEntry.java的源代碼。同時請將答案標記爲已接受,以便可以幫助他人 –
