在开始赏金后,我真的想通了!可以通过继承并提供您自己的实现来获取 Id 令牌AuthorizedCodeInstalledApp
authorize()
这是我所做的...
public class GoogleAuthCodeInstalledApp extends AuthorizationCodeInstalledApp {
public GoogleAuthCodeInstalledApp(AuthorizationCodeFlow flow, VerificationCodeReceiver receiver) {
super(flow, receiver);
}
@Override
public Credential authorize(String userId) throws IOException {
try {
Credential credential = getFlow().loadCredential(userId);
if (credential != null
&& (credential.getRefreshToken() != null
|| credential.getExpiresInSeconds() == null
|| credential.getExpiresInSeconds() > 60)) {
return credential;
}
// open in browser
String redirectUri = getReceiver().getRedirectUri();
AuthorizationCodeRequestUrl authorizationUrl
= getFlow().newAuthorizationUrl().setRedirectUri(redirectUri);
onAuthorization(authorizationUrl);
// receive authorization code and exchange it for an access token
String code = getReceiver().waitForCode();
GoogleTokenResponse response = (GoogleTokenResponse) getFlow().newTokenRequest(code).setRedirectUri(redirectUri).execute();
System.out.println(response.getIdToken()); //YES, THIS IS THE ID TOKEN!!!
// store credential and return it
return getFlow().createAndStoreCredential(response, userId);
} finally {
getReceiver().stop();
}
}
}
在你这样做之后,而不是
Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");
用:
Credential credential = new GoogleAuthCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");
更新 2018-05-29 - 我找到了一个更好,更可靠的解决方案
我发现这个解决方案的工作原理是在我们的.CredentialCreatedListener
CredentialRefreshListener
GoogleAuthorizationCodeFlow.Builder
下面是示例代码:
public Credential authorize() throws IOException {
InputStream in = GoogleLogin.class.getResourceAsStream("/google/client_secret.json");
GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));
// Build flow and trigger user authorization request.
flow = new GoogleAuthorizationCodeFlow.Builder(
HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES)
.setDataStoreFactory(DATA_STORE_FACTORY)
.setAccessType("offline")
.setCredentialCreatedListener(new AuthorizationCodeFlow.CredentialCreatedListener() {
@Override
public void onCredentialCreated(Credential credential, TokenResponse tokenResponse) throws IOException {
DATA_STORE_FACTORY.getDataStore("user").set("id_token", tokenResponse.get("id_token").toString());
}
})
.addRefreshListener(new CredentialRefreshListener() {
@Override
public void onTokenResponse(Credential credential, TokenResponse tokenResponse) throws IOException {
DATA_STORE_FACTORY.getDataStore("user").set("id_token", tokenResponse.get("id_token").toString());
}
@Override
public void onTokenErrorResponse(Credential credential, TokenErrorResponse tokenErrorResponse) throws IOException {
//handle token error response
}
})
.build();
Credential credential = new AuthorizationCodeInstalledApp(flow, serverReceiver).authorize("user");
System.out.println("Credentials saved to " + DATA_STORE_DIR.getAbsolutePath());
return credential;
}
代码几乎是不言自明的。每当通过调用 创建或刷新新内容时,都会通知侦听器,并且将从 中获取 (这实际上是一个包含字段的对象),我们将使用默认值来保存 .现在,它们将保留在本地,并且只要调用,侦听器就会自动更新。Credential
credential.refreshToken()
id_token
TokenResponse
GoogleTokenResponse
id_token
DataStoreFactory
id_token
id_token
credential.refreshToken()
