OAuth:缺少参数response_type

我正在构建一个移动Android应用程序,连接到Misfit的API以收集数据并进行一些科学研究。 (https://build.misfit.com/)Misfit的API使用OAuth授权方法,证明有点困难。

我按下按钮打开一个WebView到Misfit的Authorization页面,然后我可以登录。在我登录后,webview产生以下错误:

{"error":"invalid_request","error_description":"Missing required parameter: response_type"}

我发出该请求的代码如下: 我们的想法是为令牌发布POST并获取访问代码,将它们存储在SharedPreferences中,以便不是每个app-start都需要新的登录

public class OAuthActivity extends Activity {

public static String OAUTH_URL = "https://api.misfitwearables.com/auth/dialog/authorize";
public static String OAUTH_ACCESS_TOKEN_URL = "https://api.misfitwearables.com/auth/tokens/exchange";

public static String CLIENT_ID = "Here's a client ID";
public static String CLIENT_SECRET = "and the secret, that obviously stays hidden.";
public static String CALLBACK_URL = "http://localhost";

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_auth_o);

    String url = OAUTH_URL + "?client_id=" + CLIENT_ID;

    WebView webview = (WebView)findViewById(R.id.webview);
    webview.getSettings().setJavaScriptEnabled(true);
    final SharedPreferences prefs = this.getSharedPreferences(
            "com.iss_fitness.myapplication", Context.MODE_PRIVATE);
    webview.setWebViewClient(new WebViewClient() {
        public void onPageStarted(WebView view, String URL, Bitmap favicon) {
            String accessTokenFragment = "access_token=";
            String accessCodeFragment = "code=";

            // We hijack the GET request to extract the OAuth parameters

            if (url.contains(accessTokenFragment)) {
                // the GET request contains directly the token
                String accessToken = url.substring(url.indexOf(accessTokenFragment));
                prefs.edit().putString("Token", accessToken);

            } else if(url.contains(accessCodeFragment)) {
                // the GET request contains an authorization code
                String accessCode = url.substring(url.indexOf(accessCodeFragment));
                prefs.edit().putString("Code", accessCode);


                String query = "&client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&code=" + accessCode;
                view.postUrl(OAUTH_ACCESS_TOKEN_URL, query.getBytes());
            }

        }



    });
    webview.loadUrl(url);


}

注意:我在网上找到了这个代码,这是我作为新应用开发者最容易理解的代码之一。但是,没有任何解释,如果上面的代码被证明是错误的(或者我对它的理解),请纠正我。另外:登录后,如何将OAuth活动重定向到主要活动?

答案 0 :(得分:2)

您在授权和令牌请求中都缺少一些请求参数。将auth url更改为:

String url = String url = OAUTH_URL+ "?response_type=code" +"&client_id=" + CLIENT_ID+ "&redirect_uri=" + CALLBACK_URL + "&scope=" + SCOPE;

其中SCOPE是逗号分隔的权限字符串,如“public,birthday,email”。

并且,将令牌请求参数更改为:

String query = "grant_type=authorization_code" + "&client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&code=" + accessCode+ "&redirect_uri=" + CALLBACK_URL;
