Ios Uber API沙盒请求状态未正确更新

我正在用Swift构建一个iOS应用程序，它使用Uber API ride request端点。使用沙盒时，我无法正确更改骑乘请求状态。我试着用Uber在他们的文档中的curl命令更新它，它似乎被Uber正确地接收到（我没有收到错误回复）。然而，在我的应用程序中，当我进行另一次状态呼叫时，它不会从

处理更改

当前，当我将请求发布到
https://sandbox-api.uber.com/v1/requests
我得到下面的回复，请注意状态为
已接受

Prepare to make request -> <p2_OAuth2.OAuth2Request: 0x7fb89a854e50> { URL: https://sandbox-api.uber.com/v1/requests }
Result -> {
  destination =     {
    latitude = "37.393913269";
    longitude = "-122.0800018311";
  };
  driver =     {
    name = John;
    "phone_number" = "(555)555-5555";
    "picture_url" = "https://d1a3f4spazzrp4.cloudfront.net/uberex-sandbox/images/driver.jpg";
    rating = "4.9";
  };
  eta = 1;
  location =     {
    bearing = "-150";
    latitude = "37.33233141";
    longitude = "-122.0312186";
  };
  pickup =     {
    eta = 1;
    latitude = "37.33233141";
    longitude = "-122.0312186";
  };
  "request_id" = "39d76708-3a26-4fb7-bb0f-31f37c931a0b";
  status = accepted;
  "surge_multiplier" = 1;
  vehicle =     {
    "license_plate" = "UBER-PLATE";
    make = Toyota;
    model = Prius;
    "picture_url" = "https://d1a3f4spazzrp4.cloudfront.net/uberex-sandbox/images/prius.jpg";
  };
}

这就是奇怪的部分。我现在得到的响应是
处理
。请注意，两个请求中的行驶请求ID相同。我使用NSTimer每5秒调用一次此函数，每次调用都会得到与下面相同的响应。是
nsurnsursession
缓存一些东西，因此我得到了下面的旧响应

requestID is -> 39d76708-3a26-4fb7-bb0f-31f37c931a0b
{
  driver = "<null>";
  eta = "<null>";
  location = "<null>";
  "request_id" = "39d76708-3a26-4fb7-bb0f-31f37c931a0b";
  status = processing;
  "surge_multiplier" = 1;
  vehicle = "<null>";
}

有没有其他人遇到过优步沙箱不可靠的问题？2015年4月，我使用Ruby开发了一个应用程序，沙盒运行得非常好。我认为这可能是我迅速实施的一个方面
 是我请求的缓存策略导致我看到上面描述的不一致的响应。为了修复此问题，我在请求中添加了一个缓存策略
ReloadIgnoringCacheData
。我现在可以向Uber的沙箱发送Curl put，更新骑乘请求的状态，并使用正确的状态更新我的重复功能

完整请求如下：

class func rideStatus(uberRequestId:String, completion: (status: String) -> Void) {

  var status:String = ""

  let urlPath = "https://sandbox-api.uber.com/v1/requests/\(uberRequestId)"
  let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

  guard let endpoint = NSURL(string: urlPath) else { print("Error creating endpoint");return }
  let request = appDelegate.oauth.request(forURL: NSURL(string:urlPath)!)
  request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
  request.HTTPMethod = "GET"

  // Added this line to set request policy
  request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringCacheData

  NSURLSession.sharedSession().dataTaskWithRequest(request) { (data, response, error) -> Void in
    do {
        guard let dat = data else { throw JSONError.NoData }

        let result = try NSJSONSerialization.JSONObjectWithData(dat, options: NSJSONReadingOptions.MutableContainers)

        print(result)

        //set status
        status = result["status"] as! String

        print("found status...returning it back -> \(status)")
        completion(status: "\(status)")

    } catch let error as JSONError {
        print(error.rawValue)
        print("ERROR NEEDS TO BE HANDLED. NO RETURN FROM UBER API")
    } catch {
        print(error)
        print("ERROR NEEDS TO BE HANDLED. NO RETURN FROM UBER API")
    }
  }.resume()

}

我花了一些时间阅读NSURL请求，默认策略是缓存它们。我想我需要将appDelegate中的策略更新为
NSURLRequestReloadIgnoringLocalCacheData
。如果它正在缓存请求，这就解释了我在优步沙箱环境中看到的许多奇怪之处。我将尝试一下，并将向您汇报。
