获取Google+时出现问题;使用谷歌+;域API
我正在开发一个小型web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。我已经为我的web应用程序生成了客户端id和客户端机密 从谷歌API控制台。 使用Google+域API,我能够生成访问令牌获取Google+时出现问题;使用谷歌+;域API,api,google-plus,Api,Google Plus,我正在开发一个小型web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。我已经为我的web应用程序生成了客户端id和客户端机密 从谷歌API控制台。 使用Google+域API,我能够生成访问令牌 生成授权URL List<String> SCOPE = Arrays.asList( "https://www.googleapis.com/auth/plus.me", "https://www.googleapis.com/auth/plus.ci

//Sets up Authorization COde flow

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);
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web应用程序。
有什么建议吗?首先要检查的是,应用程序正在代表谷歌应用程序用户进行呼叫。例如,如果用户帐户是@gmail帐户,则不允许该请求。Google+Domains API仅适用于Google Apps域用户,并且仅适用于其域内的请求。谢谢Joanna。此外,如果我希望同事访问我的web应用,我需要在重定向uri中指定我的计算机的ip地址。但是当我尝试在API控制台中将重定向uri修改为“无效uri”时.有没有办法修改重定向uri?
