java - 如何在Java中获取VKontakte的授权码？

Question

public static void main(String[] args)
{
    try
    {
        OAuthClientRequest  request = OAuthClientRequest
                .tokenLocation("http://api.vkontakte.ru/oauth/authorize")
                .setClientId("45XXXXXX")
                .setUsername("XXXXXXXXX@gmail.com")
                .setPassword("XXXXXXX")
                .setClientSecret("XXXXXXXXXXXX")
                .setGrantType(GrantType.AUTHORIZATION_CODE)
                .setRedirectURI("http://oauth.vk.com/blank.html")
                .setScope("all")
                .buildBodyMessage();/** or buildHeaderMessage() or buildQueryMessage()*/
        OAuthClient oAuthClient = new OAuthClient(new URLConnectionClient());
        oAuthClient.accessToken(request);
        OAuthJSONAccessTokenResponse tokenResponse = oAuthClient.accessToken(request, OAuthJSONAccessTokenResponse.class);
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

大家好，我正在尝试在我的 VKontakte 应用程序中上传一些图片和视频。当它运行时，它抛出以下异常。

OAuthProblemException{error='unsupported_response_type', description='Invalid response! Response body is not application/json encoded', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}

我花了太多时间寻找解决方案，但我没有找到方法。请您提供任何帮助，我们将不胜感激。谢谢。

我知道这已经过时了，但我想我应该为 future 的用户添加这个可能的解决方案，以防万一我将来搜索这个!几周前我解决了类似的问题。我认为问题是

OAuthJSONAccessTokenResponse tokenResponse = oAuthClient.accessToken(request, OAuthJSONAccessTokenResponse.class);

将其更改为:

GitHubTokenResponse tokenResponse = oAuthClient.accessToken(request, GitHubTokenResponse.class);

facebook api 给我带来了与 oltu 相同的错误。
