我正在构建一个应用程序，并在沙盒环境中使用uberjavasdk。问题是uber为rideestimate、vehicle和driver类返回的null。
Mavenpom：

  1. <dependency>
  2.   <groupId>com.uber.sdk</groupId>
  3.   <artifactId>rides</artifactId>
  4.   <version>0.6.0</version>
  5. </dependency>

我的示例servlet代码：

  1. @Override
  2. protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException {
  3.     if (this.getOnceOnly()<2) {
  5.         // Fetch the user's profile.
  6.         UserProfile userProfile = uberRidesService.getUserProfile().execute().body();
  8.         response.setContentType("text/html");
  9.         response.setStatus(HttpServletResponse.SC_OK);
  10.         response.getWriter().printf("Logged in as %s%n", userProfile.getEmail());
  12.         // Publika West Gate 3.171282f 101.664771f
  13.         // Publika East Side 3.170816f 101.667760f
  14.         float startLatitude = 3.170730f;
  15.         float startLongitude =  101.665129f;
  16.         float destinationLatitude = 3.170816f;
  17.         float destinationLongitude = 101.667760f;
  19.         // Get products for location
  20.         Response<ProductsResponse> responseGet = uberRidesService.getProducts(startLatitude, startLongitude).execute();
  21.         List<Product> products = responseGet.body().getProducts();
  22.         String productId = products.get(0).getProductId();
  23.         System.out.println("responseGet: " + responseGet.code() + " " + responseGet.message());
  25.         Response<TimeEstimatesResponse> responseTime = uberRidesService.getPickupTimeEstimate( startLatitude, startLongitude, productId).execute();

  170.         System.out.println("\nride.getStatus(): "+ ride.getStatus());

  172.         if (responseUpdateRide.code()!=202) {
  173.             System.out.println("\nresponseUpdateRide.errorBody: " + responseUpdateRide.errorBody().string());
  174.         }

从上面可以看出，rideeestimate、vehicle和driver类都会导致空指针。这真的很奇怪，我可以要求乘坐成功没有车辆或司机附加到乘坐请求。我找到了一个解决办法，让通过rideeestimate返回一个空值（见我的代码上面），但我找不到一个解决办法的车辆和司机也为空。
因此，如果有任何其他方法可以使车辆和驾驶员为空，请通知我。另外，有一些关于使用沙盒更新状态的例子也不错。

当你请求一次乘坐-它被创建为“处理”状态-在这一点上，司机仍然是未知的-因为司机还没有接受这个请求。这就是为什么我们不能得到任何司机或车辆信息的原因。沙盒不会自动在骑乘中移动，但您可以手动将骑乘请求置于每个状态：
“目前，沙盒不会像生产中的实际请求那样自动更改状态。此端点使应用程序能够遍历乘坐请求的不同状态。”
有关更多详细信息，请参阅沙盒指南：https://developer.uber.com/docs/riders/guides/sandbox.
