[英]Android misfit API OAuth 2 : How to save access token
使用以下android代碼，我可以做到這一點：
在我的smarthpone Web視圖上，查看access_token
public class MainActivity extends AppCompatActivity { 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 = "my id"; public static String CLIENT_SECRET = "my secret code"; public static String CALLBACK_URL = "just a simple url"; public static String SCOPE = "public,birthday,email,tracking,session,sleep"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.other); String url = OAUTH_URL+ "?response_type=code" +"&client_id=" + CLIENT_ID+ "&redirect_uri=" + CALLBACK_URL + "&scope=" + SCOPE; WebView webview = (WebView) findViewById(R.id.aaa); webview.getSettings().setJavaScriptEnabled(true); webview.setWebViewClient(new WebViewClient() { public void onPageStarted(WebView view, String url, Bitmap favicon) { String accessTokenFragment = "access_token="; String accessCodeFragment = "code="; if (url.contains(accessCodeFragment)) { String accessCode = url.substring(url.indexOf(accessCodeFragment)); String query = "grant_type=authorization_code" + "&client_id=" + CLIENT_ID + "&client_secret=" + CLIENT_SECRET + "&" + accessCode + "&redirect_uri=" + CALLBACK_URL; view.postUrl(OAUTH_ACCESS_TOKEN_URL, query.getBytes()); System.out.println("url:" + url); System.out.println(accessCode); } System.out.println(url); if (url.contains(accessTokenFragment)) { String accessToken = url.substring(url.indexOf(accessTokenFragment)); url = url.replace("#", "?"); //view.loadUrl(url); System.out.println("token=" + accessToken); } } }); webview.loadUrl(url); } }
就像我上面說的，我設法在我的smarthpone的Web視圖上顯示access_token。 但是我無法捕獲此令牌，無法進行獲取請求以恢復用戶數據。 我是Java / android的新手，但是我有一些C語言的技能。我只是花時間去發現Java，所以我在這方面的技能很有限。 有人可以建議我嗎？
我找到了一些代碼，並制作了一個運行良好的Android應用程序。
