Google电子表格Java API不返回电子表格
问题描述：
我需要关于Google Spreadsheets Java API的帮助。即使我有电子表格，我也会收到一份空白的电子表格列表。Google电子表格Java API不返回电子表格
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
在我的代码中没有返回任何条目。而当我在浏览器中运行URL http://spreadsheets.google.com/feeds/spreadsheets/private/full时，我可以在JSON中看到电子表格条目。
这是为什么？我怎样才能解决这个问题？这里是我的代码：
import java.io.File;
import java.io.IOException;
import java.net.URL;
import java.security.GeneralSecurityException;
import java.util.Arrays;
import java.util.List;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.HttpTransport;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson.JacksonFactory;
import com.google.gdata.client.spreadsheet.SpreadsheetService;
import com.google.gdata.data.spreadsheet.SpreadsheetEntry;
import com.google.gdata.data.spreadsheet.SpreadsheetFeed;
import com.google.gdata.util.ServiceException;
public class TestSpreadsheet {
private static final String SERVICE_ACCOUNT_EMAIL = "[email protected]";
private static final File SERVICE_ACCOUNT_PKCS12_FILE = new File("./key.p12");
private static SpreadsheetService SPREADSHEETSERVICE;
public static void main(String[] args) throws GeneralSecurityException, IOException, ServiceException {
HttpTransport httpTransport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
String [] SCOPESArray= {"https://spreadsheets.google.com/feeds", "https://docs.google.com/feeds"};
List<String> SCOPES = Arrays.asList("https://spreadsheets.google.com/feeds", "https://spreadsheets.google.com/feeds/spreadsheets/private/full", "https://docs.google.com/feeds");
//final List<String> SCOPES = Arrays.asList(SCOPESArray);
GoogleCredential credential = new GoogleCredential.Builder()
.setTransport(httpTransport)
.setJsonFactory(jsonFactory)
.setServiceAccountId(SERVICE_ACCOUNT_EMAIL)
.setServiceAccountScopes(SCOPES)
.setServiceAccountPrivateKeyFromP12File(SERVICE_ACCOUNT_PKCS12_FILE)
.build();
credential.refreshToken();
SPREADSHEETSERVICE = new SpreadsheetService("test");
SPREADSHEETSERVICE.setOAuth2Credentials(credential);
URL SPREADSHEET_FEED_URL;
SPREADSHEET_FEED_URL = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");
SpreadsheetFeed feed = SPREADSHEETSERVICE.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = feed.getEntries();
if (spreadsheets.size() == 0) {
System.out.println("No spreadsheets found.");
}
}
}
请详细解释您的问题。你尝试过任何调试吗？你尝试了什么，获得了哪些结果？ – Sebastian
是的，我试着调试它。问题是代码List spreadsheets = feed.getEntries（）;不返回任何条目。而当我在浏览器中运行url https://spreadsheets.google.com/feeds/spreadsheets/private/full时，我可以在JSON中看到电子表格条目。 –
