问题描述

我正在iOS（Swift）中实施在STEP4中说明了使用承载令



将授权标头中响应中返回的access_token传递给Bearer类型以代表请求一个用户。* 

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

我不明白这一点。我应该如何在类型为Bearer的Header中传递access_token？我已经完成了如下操作

  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-键入）
 request.addValue（application / json，forHTTPHeaderField：Accept）
 
 
 
 
 request.setValue（Bearer \\ \\（base64LoginString），forHTTPHeaderField：Authorization）
 
 let session = NSURLSession.sharedSession（）
 
 let task = session.dataTaskWithRequest（request）{data，response，错误在
 
 
如果错误！= nil {
 println（error = \（error））
 return 
} 
 
 println（response = \（response））
 
 let responseString = NSString（data：data，encoding：NSUTF8StringEncoding）
 println（responseString = \（responseString） ））
 
} 
 task.resume（）
}

但我得到以下回复

  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 =可选（{message：提供的OAuth 2.0凭据无效。，代码：未授权}）


解决方案

最后我做到了：）



我改变了下面的方法和它工作

  func callRequestAPI（url：String）{
 
 var configuration = NSURLSessionConfiguration.defaultSessionConfiguration（）
 var session = NSURLSession（配置：配置）
 
 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错误：NSError？ 
 request.HTTPBody = NSJSONSerialization.dataWithJSONObject（params，options：NSJSONWritingOptions.allZeros，error：& err）
 
 let task = session.dataTaskWithRequest（request）{
 data，响应，如果让httpResponse =响应为
 
中的错误？ NSHTTPURLResponse {
 if httpResponse.statusCode！= 202 {
 println（response is not 202：\（response））
 
 return 
} 
} 
 if（error！= nil）{
 println（错误提交请求：\（错误））
返回
} 
 
 //在这里处理成功响应的数据
 var result = NSJSONSerialization.JSONObjectWithData（data，options：NSJSONReadingOptions.allZeros，error：nil）as！ NSDictionary 
 
 
 println（result）
 
如果让request_id：String = result [request_id]为？字符串{
 
 println（request_id）
} 
 
如果让driver：String = result [driver]为？字符串{
 
 println（driver）
} 
 
如果让eta：Int = result [eta]为？ Int {
 
 println（eta）
} 
 
如果让location：String = result [location]为？字符串{
 
 println（location）
} 
 
 
如果让status：String = result [status]为？字符串{
 
 println（status）
} 
 
 
如果let surge_multiplier：Int = result [surge_multiplier]为？ Int {
 
 println（surge_multiplier）
} 
 
如果让vehicle：String = result [vehicle]为？字符串{
 
 println（vehicle）
} 
 
} 
 
 task.resume（）
 
}

这里是我得到的回复，我的上述方法也给出了解析

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

I'm implementing the Uber's Request Endpoint in my iOS (Swift) App. The Request API/Endpoint requires the user authentication with the app, here is the doc.

For this I'm using this Oauth2.0 library

What I did is

  1. successfully integrated the Library in my project (xCode) with the help of given installation instructions.

  2. In My AppDelegate

    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!

  3. in my method didFinishLaunchingWithOptions of Appdelegate

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

  4. Don't forget to register url scheme i.e ("redirect_uris": ["jamesappv2://oauth/callback"])

goto your app's Target -> info Tab -> Url Types -> Click (+), image attached

  1. In AppDelegate add method given Below and Handle the Callback 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
}

  2. Now in my viewController I did like this on myBtnClick

    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)")
    }
}

Here is my debug log, I'm getting the valid response:

    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]

Notice I'm getting the valid access_token

Here I'm stuck

As per DOCs says in STEP4 *USE BEARER TOKEN

Pass the access_token returned in the response in the Authorization header with the type Bearer to make requests on behalf of a user.*

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

I am not getting the point. How should I pass the access_token in Header with type Bearer? I have done like below

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()
}

but I'm getting following response

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"})

解决方案

Finally I have done it :)

I changed the method like below and it Worked

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()

}

here is the Response I Got, Parsing is also given in my above method

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