Проблема при получении информации о Google+ Circle с помощью Google+ Domain API
Я занимаюсь разработкой небольшого веб-приложения, в которое интегрируюсь с API-интерфейсами Google+ Domain. Я использую аутентификацию OAuth2. Я сгенерировал client_id и client_secret для своего веб-приложения из консоли Google API. Используя API Домена Google+, я могу создать токен доступа.
Генерация URL авторизации
List<String> SCOPE = Arrays.asList(
"https://www.googleapis.com/auth/plus.me",
"https://www.googleapis.com/auth/plus.circles.read",
"https://www.googleapis.com/auth/plus.stream.write");
//Sets up Authorization COde flow
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(new NetHttpTransport(),
new JacksonFactory(),
"xxx","yyy",SCOPE).setApprovalPrompt("force").setAccessType("offline").build();
//Builds the uthorization URL
String url = flow.newAuthorizationUrl().setRedirectUri(<REDIRECT_URI>).build();
out.println("<div id='googleplus'></div><a href='"+url+"' rel='external' ><img src='googleplus.jpg'></a> <b>Configure</b></div>");
session.setAttribute("CodeFlow", flow);
После авторизации
GoogleAuthorizationCodeFlow flow=(GoogleAuthorizationCodeFlow)session. getAttribute("CodeFlow");
//After authorization,fetches the value of code parameter
String authorizationCode=request.getParameter("code");
//Exchanges the authorization code to get the ,access token
GoogleTokenResponse tokenResponse=flow.newTokenRequest(authorizationCode).
setRedirectUri(<REDIRECT_URI>).execute();
GoogleCredential credential = new GoogleCredential.Builder().setTransport(new NetHttpTransport()).setJsonFactory(new JacksonFactory())
.setClientSecrets("xxx", "yyy")
.addRefreshListener(new CredentialRefreshListener(){
public void onTokenErrorResponse(Credential credential, TokenErrorResponse errorResponse) throws java.io.IOException{
System.out.println("Credential was not refreshed successfully. "
+ "Redirect to error page or login screen.");
}
@Override
public void onTokenResponse(Credential credential, TokenResponse tokenResponse)
throws IOException {
System.out.println("Credential was refreshed successfully.");
System.out.println("Refresh Token :"+tokenResponse.getRefreshToken());
}
}).build();
//Set authorized credentials.
credential.setFromTokenResponse(tokenResponse);
credential.refreshToken();
Получение информации о круге:
PlusDomains plusDomains = new PlusDomains.Builder(
new NetHttpTransport(), new JacksonFactory(), credential)
.setApplicationName("DomainWebApp")
.setRootUrl("https://www.googleapis.com/")
.build();
PlusDomains.Circles.List listCircles=plusDomains.circles().list("me");
listCircles.setMaxResults(5L);
System.out.println("Circle URL:"+listCircles.buildHttpRequestUrl());
CircleFeed circleFeed=listCircles.execute();
System.out.println("Circle feed:"+circleFeed);
List<Circle> circles =circleFeed.getItems();
while (circles != null) {
for (Circle circle : circles) {
out.println("Circle name : "+circle.getDisplayName()+" Circle id : "+circle.getId());
}
// When the next page token is null, there are no additional pages of
// results. If this is the case, break.
if (circleFeed.getNextPageToken() != null) {
// Prepare the next page of results
listCircles.setPageToken(circleFeed.getNextPageToken());
// Execute and process the next page request
circleFeed = listCircles.execute();
circles = circleFeed.getItems();
} else {
circles = null;
}
}
Я получаю ошибку ниже:
com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code" : 403,
"errors" : [ {
"domain" : "global",
"message" : "Forbidden",
"reason" : "forbidden"
} ],
"message" : "Forbidden"
}
com.google.api.client.googleapis.json.GoogleJsonResponseException.from(GoogleJsonResponseException.java:145)
com.google.api.client.googleapis.services.json.AbstractGoogleJsonClientRequest.newExceptionOnError(AbstractGoogleJsonClientRequest.java:113)
Примечание. Я также включил Google+ Domain API в моей консоли Google API.REDIRECT_URI ="http://localhost:8080/DomainWebApp/oauth2callback"
так как это веб-приложение. Какие-либо предложения?
