我使用 OAuth2.0 协议连接到 facebook。一切都很好，因为我在服务器上获得了 access_token，现在我想连接到 facebook 并获得它的 API。但我收到 JSON 异常。所以这是代码：
@RequestMapping(method = RequestMethod.GET)
public String process(@ModelAttribute("user") User user, BindingResult result, Model model, HttpServletRequest request,
HttpServletResponse response) {
FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory("appid", "appsecret");
OAuth2Operations oauthOperations = connectionFactory.getOAuthOperations();
OAuth2Parameters params = new OAuth2Parameters("http://localhost:8080/shop/");
String authorizeUrl = oauthOperations.buildAuthorizeUrl(GrantType.AUTHORIZATION_CODE, params);
try {
response.sendRedirect(authorizeUrl);
LOG.error("ALL WORKING FINE>>>");
} catch (IOException e) {
LOG.error("Errorrrrr" + e);
}
String authCode = request.getParameter("code");
LOG.error("Facebook controller works... 1");
LOG.error(authCode);
if (authCode != null) {
AccessGrant accessGrant = oauthOperations.exchangeForAccess(authCode, "http://localhost:8080/shop/", null);
LOG.error("Facebook controller works... 2");
Connection<Facebook> connection = connectionFactory.createConnection(accessGrant);
LOG.error("Facebook controller works... 3");
}
return null;
}
这是一个例外：
