如何在Android中配置OAuth2连接?

okhttp oauth-2.0 post rest android

VolodymyrH · 技术社区 · 7 年前

OAuth2 服务器主要问题是我拿不到代币。我有一些必要的参数,比如clientID、secret等等。但我需要做一个岗位 OkHttp OAuth2客户端 ( library' GitHub ). 它不起作用,我也不确定它是否能发帖子。所以我编写了一个简单的OkHttp请求,并将所有内容放到post方法中。但我还是 token=null .

OkHttpClient client1 = new OkHttpClient();
      RequestBody formBody = new FormBody.Builder()
          .add("client_id", clientID)
          .add("client_secret", clientSecret)
          .add("grant_type", "password")
          .build();

      Request request = new Request.Builder()
          .url(site)
          .post(formBody)
          .build();

然后我希望看到令牌作为响应的一部分。另一个版本类似于图书馆github的指南。也许有人能解决这个问题,或者能找到更好的解决方案?

不久前,为了使用谷歌联系人,我不得不将OAuth 2.0集成到一个项目中。我使用了这个库: https://github.com/openid/AppAuth-Android

您还可以在这里看到一些重要的文档: https://developers.google.com/identity/protocols/OAuth2

碎片java:

AuthorizationServiceConfiguration serviceConfiguration = 
    new AuthorizationServiceConfiguration(
            Uri.parse(GoogleConstants.OAUTH_URL) /* auth endpoint */,
            Uri.parse(GoogleConstants.TOKEN_URL) /* token endpoint */,
            null
    );

AuthorizationRequest.Builder authRequestBuilder = new AuthorizationRequest.Builder(
            serviceConfiguration,
            getString(GoogleConstants.CLIENT_ID),
            ResponseTypeValues.CODE,
            Uri.parse(GoogleConstants.REDIRECT_URI))
            .setScope(GoogleConstants.OAUTH_SCOPE);

AuthorizationRequest request = authRequestBuilder.build();

AuthorizationService authorizationService = new AuthorizationService(getActivity());

String action = GoogleConstants.APP_ACTION;
Intent postAuthorizationIntent = new Intent(getActivity(), ExampleActivity.class);

postAuthorizationIntent.setAction(action);

PendingIntent pendingIntent = 
      PendingIntent.getActivity(getActivity(), 0, postAuthorizationIntent, 
                                PendingIntent.FLAG_UPDATE_CURRENT);

authorizationService.performAuthorizationRequest(request, pendingIntent);

活动java:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    checkIntentAction(intent);
}

...

private void checkIntentAction(@Nullable Intent intent) {
    if (intent != null) {
        String action = intent.getAction();
        if (action != null) {
            switch (action) {
                case GoogleConstants.APP_ACTION:
                    if (!intent.hasExtra(USED_INTENT)) {
                        handleAuthorizationResponse(intent);
                        intent.putExtra(USED_INTENT, true);
                    }
                    break;
                default:
                    // do nothing
            }
        }
    }
}

...

private void handleAuthorizationResponse(final @NonNull Intent intent) {
    final AuthorizationResponse response = AuthorizationResponse.fromIntent(intent);

    if (response != null) {
        final AuthorizationService service = new AuthorizationService(this);
        service.performTokenRequest(response.createTokenExchangeRequest(), 
            new AuthorizationService.TokenResponseCallback() {
              @Override
              public void onTokenRequestCompleted(@Nullable TokenResponse tokenResponse, 
                         @Nullable AuthorizationException exception) {
               ...
              }
            });
    }
}
