uber requestRide（）方法响应错误401：未授权

Question

我在尝试调用requestRide（） Uber api时出现错误。响应正文为空，响应消息为“未经授权”，错误代码为401;而onResponse（）回调方法正在执行，但onFailure（）回调方法未执行。

这里是我的调用requestRide（）和实现回调接口的代码...

private void requestForNewRide(RidesService service, int position){ 
     RideRequestParameters rideRequestParameters = new RideRequestParameters.Builder().setPickupCoordinates(PICKUP_LATITUDE, PICKUP_LONGITUDE) 
       .setProductId(productIds.get(position)) 
       .setFareId(fareIds.get(position)) 
       .setDropoffCoordinates(DROPOFF_LATITUDE, DROPOFF_LONGITUDE) 
       .build(); 
     service.requestRide(rideRequestParameters).enqueue(new Callback<Ride>() { 
      @Override 
      public void onResponse(Call<Ride> call, Response<Ride> response) { 

       if (response.isSuccessful()) { 
        Toast.makeText(CustomActivity.this, "Request ride success", Toast.LENGTH_SHORT).show(); 

        try { 
         //ride details 
         String rideId = response.body().getRideId(); 
         String rideStatus = response.body().getStatus(); 
         Integer rideEta = response.body().getEta();       //estimated time of arrival in min 
         Float rideSurgeMultiplier = response.body().getSurgeMultiplier();  //rise in price 
         Driver rideDriver = response.body().getDriver(); 
         Location rideLocation = response.body().getLocation(); 
         Vehicle rideVehicle = response.body().getVehicle(); 

         //ride driver details 
         String driverName = rideDriver.getName(); 
         String driverPhoneNumber = rideDriver.getPhoneNumber(); 
         String driverPictureUri = rideDriver.getPictureUrl(); 
         Float driverRating = rideDriver.getRating(); 

         //ride Location details 
         Float rideLocationLatitude = rideLocation.getLatitude(); 
         Float rideLocationLongitude = rideLocation.getLongitude(); 
         Integer rideLocationBearing = rideLocation.getBearing(); 

         //ride Vehicle details 
         String rideVehicleLicencePlate = rideVehicle.getLicensePlate(); 
         String rideVehicleMake = rideVehicle.getMake(); 
         String rideVehicleModel = rideVehicle.getModel(); 
         String rideVehiclePictureUrl = rideVehicle.getPictureUrl(); 

         //Log 
         Log.d("uberridedetails", "rideId: " + rideId); 
         Log.d("uberridedetails", "rideStatus: " + rideStatus); 
         Log.d("uberridedetails", "rideEta: " + rideEta); 
         Log.d("uberridedetails", "rideSurgeMultiplier: " + rideSurgeMultiplier); 
         Log.d("uberridedetails", "driverName: " + driverName); 
         Log.d("uberridedetails", "driverPhoneNumber: " + driverPhoneNumber); 
         Log.d("uberridedetails", "driverPictureUri: " + driverPictureUri); 
         Log.d("uberridedetails", "driverRating: " + driverRating); 
         Log.d("uberridedetails", "rideLocationLatitude: " + rideLocationLatitude); 
         Log.d("uberridedetails", "rideLocationLongitude: " + rideLocationLongitude); 
         Log.d("uberridedetails", "rideLocationBearing: " + rideLocationBearing); 
         Log.d("uberridedetails", "rideVehicleLicencePlate: " + rideVehicleLicencePlate); 
         Log.d("uberridedetails", "rideVehicleMake: " + rideVehicleMake); 
         Log.d("uberridedetails", "rideVehicleModel: " + rideVehicleModel); 
         Log.d("uberridedetails", "rideVehiclePictureUrl: " + rideVehiclePictureUrl); 
        } catch (Exception e) { 
         e.printStackTrace(); 
        } 
       }else { 
        Toast.makeText(CustomActivity.this, "Error: "+response.message(), Toast.LENGTH_SHORT).show(); 
       } 
      } 

      @Override 
      public void onFailure(Call<Ride> call, Throwable t) { 
       Toast.makeText(CustomActivity.this, "Failed to request ride", Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 

我已经检查帕拉姆的productId和FareId是有效的，这我从API本身得到（由调用estimateRide（）我得到的价格从对象，我已经得到了fareId。而到我有产品ID RideService对象调用的getProducts（）。

这是设置代码...

SessionConfiguration config = new SessionConfiguration.Builder() 
       .setClientId(getResources().getString(R.string.client_id)) 
       .setRedirectUri(getResources().getString(R.string.redirect_url)) 
       .setEnvironment(SessionConfiguration.Environment.SANDBOX) 
       .setScopes(Arrays.asList(Scope.PROFILE, Scope.RIDE_WIDGETS, Scope.REQUEST, Scope.REQUEST_RECEIPT)) 
       .build(); 
     UberSdk.initialize(config); 

而且......

LoginCallback loginCallback = new LoginCallback() { 
      @Override 
      public void onLoginCancel() { 
       // User canceled login 
       Toast.makeText(CustomActivity.this, "User canceled login", Toast.LENGTH_SHORT).show(); 
      } 
      @Override 
      public void onLoginError(@NonNull AuthenticationError error) { 
       // Error occurred during login 
       Toast.makeText(CustomActivity.this, "Error occurred during login", Toast.LENGTH_SHORT).show(); 
      } 
      @Override 
      public void onLoginSuccess(@NonNull AccessToken accessToken) { 
       // Successful login! The AccessToken will have already been saved. 
       Toast.makeText(CustomActivity.this, "Successful login! The AccessToken will have already been saved.", Toast.LENGTH_SHORT).show(); 
       createSession(); 
      } 
      @Override 
      public void onAuthorizationCodeReceived(@NonNull String authorizationCode) { 
       Toast.makeText(CustomActivity.this, "Authorization code received", Toast.LENGTH_SHORT).show(); 
       createSession(); 
      } 
     }; 
     AccessTokenManager accessTokenManager = new AccessTokenManager(getApplicationContext()); 
     LoginManager loginManager = new LoginManager(accessTokenManager, loginCallback); 
     loginManager.setRedirectForAuthorizationCode(true); 
     loginManager.login(this); 
     mAccessTokenManager = accessTokenManager; 
     mLoginManager = loginManager; 

注1：这是我使用的范围...

Scope.PROFILE, Scope.RIDE_WIDGETS, Scope.REQUEST, Scope.REQUEST_RECEIPT 

注2：我与我的开发人员帐户登录。

让我知道是否应该提及任何其他细节。

Answer 1

绝对我已经找到了我自己的解决方案。

我注意到onLoginSuccess()回调方法仅在我使用GENERAL SCOPE时才被调用。

每当我使用RESTRICTED SCOPE时，该方法不会被调用，而是调用另一个名为onAuthorizationCodeReceived()的回调方法。

然后我发现，每当onAuthorizationCodeReceived()方法被调用，还有保存在AccessTokenManager对象没有访问令牌。因此，如果没有访问令牌，当我尝试请求骑乘错误时，返回“未经授权”。

因此，我试图弄清楚如何使用授权码生成Access令牌。我在Android部分找不到有关此过程的文档。然后我找到了REST Web服务api中的解决方案。

注：没有在尤伯杯文件onAuthorizationCodeReceived回调（）方法中没有提及。
