【问题描述】：
我已经完成了 oauth 2.0 身份验证并获得了令牌。现在，当我尝试添加工作表时，我在 service.insert 上遇到错误。
有 2 个类，一个是我获取令牌的地方，另一个是我传递凭据然后添加工作表的地方 -：
请看以下代码-:
第一类
import com.google.api.client.auth.oauth2.Credential;

public static void main (String args[]) throws IOException, ServiceException {
Credential credencial = getCredentials();
Abc.printDocuments(credencial);
}
/**

* @return OAuth 2.0 Credential instance.
*/
static Credential getCredentials() throws IOException {
HttpTransport transport = new NetHttpTransport();
JacksonFactory jsonFactory = new JacksonFactory();
// Step 1: Authorize -->
String authorizationUrl =
new GoogleAuthorizationCodeRequestUrl(CLIENT_ID, REDIRECT_URI, SCOPES).build();
// Point or redirect your user to the authorizationUrl.
System.out.println("Go to the following link in your browser:");
System.out.println(authorizationUrl);
// Read the authorization code from the standard input stream.
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is the authorization code?");
String code = in.readLine();
// End of Step 1 <--
// Step 2: Exchange -->
GoogleTokenResponse response =
new GoogleAuthorizationCodeTokenRequest(transport, jsonFactory, CLIENT_ID, CLIENT_SECRET,
code, REDIRECT_URI).execute();
// End of Step 2 <--
System.out.println(response);
// Build a new GoogleCredential instance and return it.
return new GoogleCredential.Builder().setClientSecrets(CLIENT_ID, CLIENT_SECRET)
.setJsonFactory(jsonFactory).setTransport(transport).build()
.setAccessToken(response.getAccessToken()).setRefreshToken(response.getRefreshToken());
}
