Question

我在我的iOS（Swift）应用中实现了Uber's Request Endpoint。 Request API / Endpoint需要用户对应用进行身份验证，此处为doc。

我做的是

在给定的安装说明的帮助下，成功地将库集成到我的项目（xCode）中。

在我的AppDelegate中

let uber_OAuth_Settings = [
"client_id": "XXXXXXX9vtKzobvXXXXXX",
"client_secret": "EXXXXXXXXyFUNCa_Wez6AXXXXXXXnrXtxus",
"authorize_uri": "https://login.uber.com/oauth/authorize",
"token_uri": "https://login.uber.com/oauth/token",
"redirect_uris": ["jamesappv2://oauth/callback"],   // don't forget to register this scheme
] as OAuth2JSON

var oauth：OAuth2CodeGrant！

在Appdelegate的方法didFinishLaunchingWithOptions中

 oauth = OAuth2CodeGrant(settings: uber_OAuth_Settings)
oauth.viewTitle = "Uber Login Service"      // optional
oauth.verbose = true // For Logs

不要忘记注册网址方案，即（"redirect_uris": ["jamesappv2://oauth/callback"]）

转到您应用的目标 - ＆gt;信息标签 - ＆gt;网址类型 - ＆gt;单击（+），附加图像

enter image description here

在AppDelegate中添加下面给出的方法并处理回调URL

func application(application: UIApplication,
openURL url: NSURL,
sourceApplication: String?,
annotation: AnyObject?) -> Bool {
    // you should probably first check if this is your URL being opened

   var splitUrl = url.absoluteString!.componentsSeparatedByString(":")

    if splitUrl[0] == ("jamesappv2") {

        oauth.handleRedirectURL(url)
    }

    return true
}

现在在我的viewController中，我在myBtnClick

上做了这个

let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

let url = appDelegate.oauth.authorizeURL()
UIApplication.sharedApplication().openURL(url)        
appDelegate.oauth.onAuthorize = { parameters in
    println("Did authorize with parameters: \(parameters)")

    self.navigationController?.pushViewController(self.PersonalDriverUber_VC, animated: true)
//On Authorization Goto another ViewController using pushViewController of navigationcontroller Method

}
appDelegate.oauth.onFailure = { error in        // `error` is nil on cancel
    if nil != error {
        println("Authorization went wrong: \(error!.localizedDescription)")
    }
}

这是我的调试日志，我得到了有效的回复：

    OAuth2: Handling redirect URL jamesappv2://oauth/callback?state=4B0EB812&code=0sXXXXXXTX7yEbS1XXXXXHuw
OAuth2: Successfully validated redirect URL
OAuth2: Authorizing against https://login.uber.com/oauth/token?state=38158941&grant_type=authorization_code&code=0sXXXXXXXX1jxTrdFQT9Huw&client_secret=EIXXXXXXXNCa_Wez6XXXXXw0BlnrXtxus&client_id=fXXXXXXXy2LOUo9vtKXXXXXQ1nUDO&redirect_uri=jamesappv2%3A%2F%2Foauth%2Fcallback
OAuth2: Exchanging code 0swNXXXXX7yXXXXXXdFQT9Huw with redirect jamesappv2://oauth/callback for token at Optional("https://login.uber.com/oauth/token")
OAuth2: Did receive access token: Dfq3XXXXXXuWgpaqFXXXXXXXgXW, refresh token: EmStT7FEXHRMlS8odPzs1nsha0ObjK
Did authorize with parameters: [token_type: Bearer, expires_in: 2592000, access_token: XXXXXXOZuWgXXXXXXXXuJYOmgXW, refresh_token: EXXXXXHRMlS8oXXXXXXXa0ObjK, scope: profile, last_authenticated: 1430121470]

注意我获得了有效的access_token

我坚持

根据DOCs在STEP4 *使用承载者中所说的

将Authorizer标头中响应中返回的access_token传递给Bearer类型，以代表用户发出请求。*

curl -H 'Authorization: Bearer YOUR_ACCESS_TOKEN' 'https://api.uber.com/v1/products?latitude=37.7759792&longitude=-122.41823'

我没有明白这一点。我应该如何在类型为Bearer的Header中传递access_token？我在下面做了

func callRequestAPI(url:String){

    let request = appDelegate.oauth.request(forURL: NSURL(string:url)!)



    request.HTTPMethod = "POST"


    let postString = "product_id="+selectedUberProductId+"&start_latitude="+start_lat+"&start_longitude="+start_lng+"&end_latitude="+end_lat+"&end_longitude="+end_lng

    println(postString)


    let tempData: NSData = appDelegate.oauth.accessToken.dataUsingEncoding(NSUTF8StringEncoding)!
    let base64LoginString = tempData.base64EncodedStringWithOptions(nil)

    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")




   request.setValue("Bearer \(base64LoginString)", forHTTPHeaderField: "Authorization")

    let session = NSURLSession.sharedSession()

    let task = session.dataTaskWithRequest(request) { data, response, error in


        if error != nil {
            println("error=\(error)")
            return
        }

        println("response = \(response)")

        let responseString = NSString(data: data, encoding: NSUTF8StringEncoding)
        println("responseString = \(responseString)")

    }
    task.resume()
}

但是我得到了以下回复

response = <NSHTTPURLResponse: 0x1a284b50> { URL: https://sandbox-api.uber.com/v1/requests } { status code: 401, headers {
"Content-Length" = 75;
"Content-Type" = "application/json";
Date = "Mon, 27 Apr 2015 10:22:01 GMT";
Server = nginx;
"Strict-Transport-Security" = "max-age=31536000; includeSubDomains; preload";
"x-uber-app" = "uberex-sandbox";
"x-xss-protection" = "1; mode=block";
} }
responseString = Optional({"message":"Invalid OAuth 2.0 credentials provided.","code":"unauthorized"})

最后我做到了：）

我改变了下面的方法并且工作了

func callRequestAPI(url:String){

    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration)

    let params:[String: AnyObject] = [
        "product_id" : selectedUberProductId,
        "start_latitude" : start_lat,
        "start_longitude" : start_lng,
        "end_latitude" : end_lat,
        "end_longitude" : end_lng]



    let request = appDelegate.oauth.request(forURL: NSURL(string:url)!)
    request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.HTTPMethod = "POST"
    var err: NSError?
    request.HTTPBody = NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.allZeros, error: &err)

    let task = session.dataTaskWithRequest(request) {
        data, response, error in

        if let httpResponse = response as? NSHTTPURLResponse {
            if httpResponse.statusCode != 202 {
                println("response was not 202: \(response)")

                return
            }
        }
        if (error != nil) {
            println("error submitting request: \(error)")
            return
        }

        // handle the data of the successful response here
        var result = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.allZeros, error: nil) as! NSDictionary


        println(result)

        if let request_id: String = result["request_id"] as? String{

            println(request_id)
        }

        if let driver: String = result["driver"] as? String{

            println(driver)
        }

        if let eta: Int = result["eta"] as? Int{

            println(eta)
        }

        if let location: String = result["location"] as? String{

            println(location)
        }


        if let status: String = result["status"] as? String{

            println(status)
        }


        if let surge_multiplier: Int = result["surge_multiplier"] as? Int{

            println(surge_multiplier)
        }

        if let vehicle: String = result["vehicle"] as? String{

            println(vehicle)
        }

    }

    task.resume()

}

这是我得到的响应，解析也在上面的方法中给出

{
  driver = "<null>";
  eta = 15;
  location = "<null>";
  "request_id" = "ea39493d-b718-429f-8710-00a34dcdaa93";
  status = processing;
  "surge_multiplier" = 1;
  vehicle = "<null>";
}

享受

Answer 2

针对Swift 2进行了更新。我使用了与Qadir在他的问题中描述的oauth相同的设置和库。我更新了他在Swift 2工作的请求。希望这有助于其他人。

uberRequest：

    let params:[String:AnyObject] = [
        "product_id" : uberProduct,
        "start_latitude" : userLat,
        "start_longitude" : userLng,
        "end_latitude" : barLat,
        "end_longitude" : barLng]

    let urlPath = "https://sandbox-api.uber.com/v1/requests"
    let appDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
    var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
    var session = NSURLSession(configuration: configuration)

    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.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions.PrettyPrinted)

    request.HTTPMethod = "POST"

    print("Prepare to make request -> \(request)")

    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){ data, response, error in
        if error != nil{
            print("Error -> \(error)")
            return
        }

        do {
            let result = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers)

            print("Result -> \(result)")

        } catch {
            print("Error -> \(error)")
        }
    }

    task.resume()

它返回：

Result -> Optional(["driver": <null>, "request_id": 5834384c-7283-4fe6-88a7-e74150c6ab30, "surge_multiplier": 1, "location": <null>, "vehicle": <null>, "status": processing, "eta": <null>])

要使用令牌，只需按照OAuth2库中说明的步骤5操作，就像您开始尝试自己第二次签名之前所做的那样。该请求已经签署并设置了Bearer令牌，您无需做任何事情：

let url = NSURL(string: "https://api.uber.com/v1/products?latitude=37.7759792&longitude=-122.41823")
let req = appDelegate.oauth.request(forURL: url)

// customize your request, if needed. E.g. for POST:
req.HTTPMethod = "POST"

// send the request
let session = NSURLSession.sharedSession()
let task = session.dataTaskWithRequest(req) { data, response, error in
    if nil != error {
        // something went wrong
    }
    else {
        // check the response and the data
        // you have just received data with an OAuth2-signed request!
    }
}
task.resume()
