Question

我正在使用Swift构建一个使用优步API乘坐请求端点的iOS应用。使用Sandbox我无法正确更改乘车请求状态。我已经尝试用Uber在他们的文档中使用curl命令来更新它，它似乎被Uber正确接收（我没有收到错误）。但是，在我的应用程序中，当我进行另一个状态调用时，它不会从processing更改。

目前，当我将请求发布到https://sandbox-api.uber.com/v1/requests时，我会收到以下回复，请注意状态为accepted。

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";
  };
}

现在已经成功提交了乘车请求，我使用上面的响应中的requestID来调用我的rideStatus函数。这是我要求的。

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"


    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()

}

所以这是奇怪的部分。我现在得到的回复是processing。注意，两个请求中的ride requestId是相同的。我每5秒钟使用NSTimer调用此函数，每次调用时我不断回复的响应与下面相同。是NSURLNSURLSession缓存了一些东西，所以我在下面得到旧回复。

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>";
}

另外，如果我使用下面的curl请求，我似乎无法一致地更改状态。我已经尝试将其更改为已接受，但它似乎无法正常工作。如果我将其更改为complete，它会零星工作并complete我的骑行。但是，我仍然在我的rideStatus函数中显示processing。我知道它completed的唯一方法是，如果我重新启动我的模拟器并发出新的POST请求，我将从Uber获得另一个requestId。这是我更新状态的卷曲：

curl -X "PUT" "https://sandbox-api.uber.com/v1/sandbox/requests/39d76708-3a26-4fb7-bb0f-31f37c931a0b" \
  -H "Authorization: Bearer RYV7mXXXXXXXXXXXXXXXXXXXXXyzLw" \
  -H "Content-Type: application/json"\
  -d '{"status":"accepted"}'

有没有其他人遇到优步沙盒不可靠的问题？我在2015年4月使用Ruby开发了一个应用程序，沙盒工作得很好。我认为这可能是我的Swift实现中的一些内容。

我的请求的缓存策略导致我看到上面描述的不一致的响应。为了解决这个问题，我在我的请求中添加了ReloadIgnoringCacheData的缓存策略。我现在可以将Curl PUT发送到Uber的沙箱，更新乘坐请求的状态，并以正确的状态更新我的重复功能更新。

以下完整请求：

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()

}
