我正在使用移动SoundCloud Web身份验证页面登录到SoundCloud的Android应用程序上工作. SoundCloud移动Web身份验证页面为您提供了使用SoundCloud,Facebook或Google登录的三个选项.该界面如下所示：

到目前为止,我可以使用SoundCloud和Facebook凭据登录,但是使用Google时失败.这是我正在做的删节版：

public class SoundCloudActivity extends Activity {    ...    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.twitter_login_layout);        ...        loadingProgressbar = (Progressbar) findVIEwByID(R.ID.loading_progressbar);        WebVIEw webVIEw = (WebVIEw) findVIEwByID(R.ID.login_webvIEw);        webVIEw.setVerticalScrollbarEnabled(true);        webVIEw.setHorizontalScrollbarEnabled(true);        webVIEw.setWebVIEwClIEnt(new SoundclouDWebVIEwClIEnt());        webVIEw.getSettings().setJavaScriptEnabled(true);        webVIEw.getSettings().setAllowfileAccess(true);        webVIEw.getSettings().setPluginState(PluginState.ON);        webVIEw.getSettings().setJavaScriptCanopenwindowsautomatically(true);        authUrl = API.wrapper.authorizationCodeUrl(Endpoints.CONNECT, Token.ScopE_NON_EXPIRING).toString();        webVIEw.loadUrl(authUrl);    }    private class SoundclouDWebVIEwClIEnt extends WebVIEwClIEnt {        public boolean shouldOverrIDeUrlLoading(WebVIEw vIEw, String url) {            Log.d(TAG, "shouldOverrIDeUrlLoading(): url: "+url);            if (url.startsWith(REDIRECT_URI.toString())) {                Uri result = Uri.parse(url);                new Thread(new Runnable() {                    @OverrIDe                    public voID run() {                        try {                            token = API.wrapper.authorizationCode(code, Token.ScopE_NON_EXPIRING);                        } catch (IOException e) {                            e.printstacktrace();                        }                        ...                    }                }).start();                return true;            } else if (url.startsWith("authorize")) {                return false;            } else if (url.startsWith("http")) {                vIEw.loadUrl(url);            }            return true;        }        @OverrIDe        public voID onReceivedError(WebVIEw vIEw, int errorCode,                String description, String failingUrl) {            Log.d(TAG, "Call one rror with error: "+description);            super.onReceivedError(vIEw, errorCode, description, failingUrl);        }        @OverrIDe        public voID onPageStarted(WebVIEw vIEw, String url, Bitmap favicon) {            Log.d(TAG,"onPageStarted(): url: "+url+" favicon: "+favicon);            loadingProgressbar.setVisibility(Progressbar.VISIBLE);            super.onPageStarted(vIEw, url, favicon);        }        @OverrIDe        public voID onPageFinished(WebVIEw vIEw, String url) {            loadingProgressbar.setVisibility(Progressbar.GONE);            super.onPageFinished(vIEw, url);        }    }}

选择使用Google时,它会将我重定向到熟悉的Google登录页面.然后,当我输入用户名和密码时,它会将我重定向到空白页面,并且不执行任何 *** 作,包括不向我提供身份验证令牌.这是登录后生成的空白页面的示例URL：

https://accounts.google.com/o/oauth2/auth?client_id=984739005367.apps.googleusercontent.com&redirect_uri=postmessage&response_type=code%20token%20id_token%20gsession&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.email%20https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fplus.login%20https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fuserinfo.profile&state=539399140%7C0.873620491&access_type=offline&request_visible_actions=http%3A%2F%2Fschemas.google.com%2FAddActivity%20http%3A%2F%2Fschemas.google.com%2FListenActivity%20http%3A%2F%2Fschemas.google.com%2FCreateActivity&after_redirect=keep_open&cookie_policy=single_host_origin&include_granted_scopes=true&proxy=oauth2relay763648117&origin=https%3A%2F%2Fsoundcloud.com&

我想知道WebVIEw中是否缺少我需要的设置.我已经必须使其他人能够使用SoundCloud移动网页中的其他功能.任何建议将不胜感激.

解决方法:

因此,Google使用跨站点JavaScript注入来完成身份验证过程,这要求在Google身份验证过程中仍打开SoundCloud登录窗口.要解决此问题,您需要强制/允许Google身份验证进入新的WebvIEw窗口.我在github上创建了一个演示项目,该项目显示了整个过程here.

这是完成工作的课程,请查看全文以获取更多详细信息：
