Question

我已经从saved-access-token和saved-refresh-token初始化了GoogleCredential变量。但我不知道检查它是否过期了？

我知道GoogleCredential有一个函数getExpiresInSeconds。但是，如果我从saved-access-token和saved-refresh-token初始化GoogleCredential，则函数getExpiresInSeconds将返回null。

此案例getExpiresInSeconds不会为空

mResponse = mFlow.newTokenRequest(code).setRedirectUri(REDIRECT_URI).execute();
mCredential =  new GoogleCredential.Builder().setClientSecrets(CLIENT_ID, CLIENT_SECRET).setJsonFactory(mJsonFactory).setTransport(mHttpTransport).build();
mCredential.setFromTokenResponse(mResponse);
mCredential.getExpiresInSeconds() // will return expired value in second

但在这种情况下

String accessTokenSave = mPrefs.getString(GOOGLE_DRIVE_TOKEN, "NO KEY");
String accessRefreshTokenSave = mPrefs.getString(GOOGLE_DRIVE_REFRESH_TOKEN, "NO KEY");

mHttpTransport = new NetHttpTransport();
mJsonFactory = new JacksonFactory();
mCredential = new GoogleCredential.Builder()
.setClientSecrets(CLIENT_ID, CLIENT_SECRET)
.setJsonFactory(mJsonFactory)
.setTransport(mHttpTransport).build();

mCredential.setAccessToken(accessTokenSave);
mCredential.setRefreshToken(accessRefreshTokenSave);
mCredential.getExpiresInSeconds() // will return null value

那么如何检查mCredential案例从accessTokenSave和accessRefreshTokenSave加载

访问令牌在一小时后到期，而刷新令牌将一直有效，直到用户撤销为止。但是，您永远不应该依赖这些时间，而是准备好在凭据不再有效时捕获异常，并做出相应的反应。
