我正在使用带有以下代码的 Spring Social Facebook：
FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(
"XXXXXXXX", "YYYYYYYY");
OAuth2Operations oauthOperations = connectionFactory.getOAuthOperations();
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException {
String code = request.getParameter("code");
if (StringUtil.isNotBlankStr(code)) {
AccessGrant accessGrant = oauthOperations.exchangeForAccess(code,
"http://localhost:8888/Login", null);
Connection<Facebook> connection = connectionFactory
.createConnection(accessGrant);
Facebook facebook = connection != null ? connection.getApi()
: new FacebookTemplate();
facebook.feedOperations().updateStatus(
"I'm trying out Spring Social!");
} else {
OAuth2Parameters params = new OAuth2Parameters();
params.setRedirectUri("http://localhost:8888/Login");
params.setScope("publish_stream");
params.setScope("email");
params.setScope("offline_access");
String authorizeUrl = oauthOperations.buildAuthorizeUrl(
GrantType.AUTHORIZATION_CODE, params);
response.sendRedirect(authorizeUrl);
return;
}
}
执行该行时：
oauthOperations.exchangeForAccess ...
收到此错误：
