使用 Google+ Domain API 获取 Google+ Circle 信息时出现问题 [英] Issue while fetching Google+ Circle information using Google+ Domain API
问题描述
我正在开发一个小型网络应用程序,其中我正在与 Google+ 域 API 集成.我正在使用 OAuth2 身份验证.我为我的 Web 应用程序生成了 client_id 和 client_secret来自 Google API 控制台.使用 Google+ 域 API,我能够生成访问令牌.
I am developing a small web application wherein I am integrating with Google+ Domain API's. I am using OAuth2 authentication.I have generated client_id and client_secret for my web application from Google API console. Using Google+ Domain API's, I am able to generate the access token.
生成授权网址
Generating authorization URL
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);
授权后
After authorization
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();
获取圈子信息:
Fetching circle information:
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;
}
}
我收到以下错误:
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)
注意:我还在我的 Google API 控制台中启用了 Google+ 域 API.REDIRECT_URI ="http://localhost:8080/DomainWebApp/oauth2callback"
因为它是一个网络应用程序.有什么建议吗?
Note: I have also enabled Google+ Domain API in my Google API Console.
REDIRECT_URI ="http://localhost:8080/DomainWebApp/oauth2callback"
since it's a web app.
Any Suggestions?
推荐答案
首先要检查的是应用程序是否代表 Google Apps 用户进行调用.例如,如果用户帐户是@gmail 帐户,则该请求将不被允许.Google+ Domains API 仅适用于 Google Apps 域用户,并且仅适用于其域内的请求.
The first thing to check is that the application is making the call on behalf of a Google Apps user. If the user account is, for example, an @gmail account, the request will not be allowed. The Google+ Domains API only works for Google Apps domain users, and only for requests within their domain.
