【问题描述】：

我只能通过 Fabric 授权并获得 userID 和 userName。但我需要获得“accessToken”。 我尝试发送类似这样的简单请求：

Alamofire.request(.GET, "https://api.twitter.com/1.1
/oauth2/token")
         .responseJSON  response in
             print(response)
         

但我没有成功（

还有一个...如何正确传递ConsumerKey 和ConsumerSecret 作为参数？

【参考方案1】：

这是答案，也许它可以帮助某人：

let consumerKey = "yourConsumerKey"
let consumerSecret = "yourConsumerSecret"
let credentialsString = "\(consumerKey):\(consumerSecret)"
let credentialsData = (credentialsString as NSString).dataUsingEncoding(NSUTF8StringEncoding)
let base64String = credentialsData!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
let headers = ["Authorization": "Basic \(base64String)", "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"]
let params: [String : AnyObject] = ["grant_type": "client_credentials"]

Alamofire.request(.POST, "https://api.twitter.com/oauth2/token", headers: headers, parameters: params)
     .responseJSON  response in switch response.result 
         case .Success(let JSON):

            let response = JSON as! NSDictionary
            let userModel = response

            print("----------------")
            print("")
            print("userModel from TW")
            print(userModel)
            print("")
            print("----------------")

         case .Failure(let error):

            print("Request failed with error: \(error)")
