我正在我的iOS(Swift)应用程序中实现Uber's Request Endpoint。 Request API/Endpoint需要使用应用程序进行用户身份验证,这是doc。
为此,我正在使用此Oauth2.0 library
我所做的是
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!
didFinishLaunchingWithOptions
中的 oauth = OAuth2CodeGrant(settings: uber_OAuth_Settings)
oauth.viewTitle = "Uber Login Service" // optional
oauth.verbose = true // For Logs
"redirect_uris": ["jamesappv2://oauth/callback"]
)转到应用程序的目标->信息选项卡->网址类型->单击(+),附加图片
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
}
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,我得到了有效的响应:
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,我得到了有效的access_token
我在这里卡住
按照DOCs在STEP4中所说*使用BEARER TOKEN
*将响应中返回的access_token传递给类型为Bearer的Authorization header ,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'
我不明白这一点。我应该如何在Bearer中传递类型为Bearer的access_token?我已经完成如下
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()
}
但我得到以下回应
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"})
最佳答案
终于我做到了:)
我更改了如下所示的方法,并且可以正常工作
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,我上面的方法中也给出了解析
{
driver = "<null>";
eta = 15;
location = "<null>";
"request_id" = "ea39493d-b718-429f-8710-00a34dcdaa93";
status = processing;
"surge_multiplier" = 1;
vehicle = "<null>";
}
享受
