我正在尝试使用stackexchange api构建应用程序,并且用户在通过stackoverflow.com对自身进行身份验证后将能够使用该应用程序。但是我得到的问题是重新打开应用程序后完成身份验证后,我正在onResume()中寻找意图的数据,因此它为null,但应包含带有访问令牌的回调URL。当我打开传递给浏览器进行身份验证的URL时,与回调URL关联了access_token,但在应用程序中,我得到的是null!
public class MainActivity extends AppCompatActivity {
private static final String TAG = "MainActivity";
Uri uri = new Uri.Builder()
.scheme("https")
.authority("stackoverflow.com")
.appendPath("oauth").appendPath("dialog")
.appendQueryParameter("client_id", "14910")
.appendQueryParameter("scope", "read_inbox")
.appendQueryParameter("redirect_uri", "https://stackoverflow.com/oauth/login_success")
.build();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d(TAG, "onCreate: uri : " + uri);
Intent intent = new Intent(
Intent.ACTION_VIEW,
uri);
startActivity(intent);
}
@Override
protected void onResume() {
super.onResume();
Log.d(TAG, "onResume: intent: " + getIntent());
Log.d(TAG, "onResume: uri: " + getIntent().getData());
Uri uri = getIntent().getData();
if (uri != null && uri.toString().startsWith("stackoverflow.com/oauth/login_success")) {
String code = uri.getQueryParameter("code");
if (code != null) {
Log.d(TAG, "onResume: code:" + code);
} else if (uri.getQueryParameter("error") != null) {
Log.d(TAG, "onResume: error" + uri.getQueryParameter("error"));
}
}else{
Log.d(TAG, "onResume: else");
}
}
}
...
<activity android:name=".MainActivity"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:host="stackoverflow.com"
android:pathPrefix="/oauth/login_success"
android:scheme="https" />
</intent-filter>
</activity>
...
如果我在这里显示uri传递了意图:
https://stackoverflow.com/oauth/dialog?client_id=14910&scope=read_inbox&redirect_uri=https%3A%2F%2Fstackoverflow.com%2Foauth%2Flogin_success
,然后在身份验证后获得该响应URL:
https://stackoverflow.com/oauth/login_success#access_token=nwIxeGi73Bf0rA9Ij4iwcQ))&expires=86400
