android OAuth-2.0 google 使用 webview 登录以获取用户信息 [英] android OAuth-2.0 google login for user info using webview

问题描述

我正在创建允许用户使用 facebook 或 google 帐户登录的应用程序.他们按下登录"按钮，然后他们被要求使用 Facebook 或谷歌登录，当他们选择其中之一时，webview 会弹出.

I'm creating app that will allow user to login with facebook or google account. They press button "LOGIN" and then they are asked to login using facebook or google, when they choose one of these the webview pop up.

问题在于谷歌身份验证，阅读了一些文章并搜索了网络，仍然可以在没有客户经理的情况下进行谷歌登录，我知道他们改变了一些东西.

Problem is with google autentication, read some articles and searched the web, is still possible to make google login without Account Manager, I know that they changed something.

如果可能的话，也许可以提供一些我可以处理或看到它工作的示例.我试过这个:http://blog.doityourselfandroid.com/2011/08/06/oauth-2-0-flow-android/刚刚编辑的不是纬度而是用户信息，总是收到错误 400.

If it's possible maybe some example on which I can work on or see it working. I tried with this: http://blog.doityourselfandroid.com/2011/08/06/oauth-2-0-flow-android/ Just edited not to do latitude but user info and always getting error 400.

问题出在我创建 AccessTonekResponse 并执行的地方，因为它需要客户端密码，而我无法在 google api 页面上仅在 Web 应用程序中找到客户端密码，在已安装的应用程序中没有任何内容.

Problem is in line where I create AccessTonekResponse and execute because it require client secret and I cant find client secret on google api page only in web app nothing in installed app.

        public void onPageFinished(WebView view, String url)  {  

            if (url.startsWith(OAuth2ClientCredentials.REDIRECT_URI)) {
                try {

                    if (url.indexOf("code=")!=-1) {

                        String code = extractCodeFromUrl(url);
                        System.out.println(code);
                          AccessTokenResponse accessTokenResponse = new GoogleAuthorizationCodeGrant(new NetHttpTransport(),
                                          new JacksonFactory(),
                                          OAuth2ClientCredentials.CLIENT_ID,
                                          OAuth2ClientCredentials.CLIENT_SECRET,
                                          code,
                                          OAuth2ClientCredentials.REDIRECT_URI).execute();

                          CredentialStore credentialStore = new SharedPreferencesCredentialStore(prefs);
                          credentialStore.write(accessTokenResponse);
                          view.setVisibility(View.INVISIBLE);
                          startActivity(new Intent(OAuthAccessTokenActivity.this,LatitudeApiSample.class));
                    } else if (url.indexOf("error=")!=-1) {
                        view.setVisibility(View.INVISIBLE);
                        new SharedPreferencesCredentialStore(prefs).clearCredentials();
                        startActivity(new Intent(OAuthAccessTokenActivity.this,LatitudeApiSample.class));
                    }

                } catch (IOException e) {
                    e.printStackTrace();
                    System.out.println(e.getLocalizedMessage());
                }

            }
            System.out.println("onPageFinished : " + url);

        }

推荐答案

您可能在 Google 的 API 控制台作为已安装的应用程序类型为 Android.这仅适用于 AuthenticationManager.如果您想自己实施流程，请使用应用程序类型其他，您将获得所需的客户端密钥.

You probably created your client ID in Google's API Console as Installed Application with Application Type Android. This is only meant for use with AuthenticationManager. If you want to implement the flow yourself, use Application Type Other an you'll get the client secret you need.
