基于Swift语言开发微信、QQ和微博的SSO授权登录代码分析

3，配置工程

func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {  
        // Override point for customization after application launch.  
          
        //向微信注册  
        WXApi.registerapp(kWXAPP_ID)  
          
        return true  
    } 

2，授权登录

1. override func viewDidLoad() {  
           super.viewDidLoad()  
           // Do any additional setup after loading the view,typically from a nib.  
             
           NSNotificationCenter.defaultCenter().addobserver(self,selector:"onRecviceWX_CODE_Notification:",name: "WX_CODE",object: nil)  
             
             
           let sendBtn:UIButton = UIButton()  
           sendBtn.frame = CGRectMake(30,100,kIPHONE_WIDTH-60,40)  
           sendBtn.backgroundColor = UIColor.redColor()  
           sendBtn.setTitleColor(UIColor.whiteColor(),forState: UIControlState.normal)  
           sendBtn.setTitle("Swift版本之微信授权登录",forState: UIControlState.normal)  
           sendBtn.addTarget(self,action: "sendBtnClick:",forControlEvents: UIControlEvents.TouchUpInside)  
           self.view.addSubview(sendBtn)  
             
             
           headerImg = UIImageView(frame: CGRectMake(30,160,120,120))  
           headerImg.backgroundColor = UIColor.yellowColor()  
           self.view.addSubview(headerImg)  
             
           nicknameLbl.frame = CGRectMake(170,kIPHONE_WIDTH-60-140,40)  
           nicknameLbl.backgroundColor = UIColor.lightGrayColor()  
           nicknameLbl.textColor = UIColor.purpleColor()  
           nicknameLbl.textAlignment = NSTextAlignment.Center  
           self.view.addSubview(nicknameLbl)  
             
       }  
         
         
       func sendBtnClick(sneder:UIButton)  
       {  
           sendWXAuthRequest()  
       }  
         
       //微信登录 第一步  
       func sendWXAuthRequest(){  
             
           let req : SendAuthReq = SendAuthReq()  
           req.scope = "snsapi_userinfo,snsapi_base"  
           WXApi .sendReq(req)  
       }

//第二步 登录成功回调  
   func tencentDidLogin() {  
       let accesstoken = tencentOAuth.accesstoken  
  
       println("accesstoken:\(accesstoken)") //641B23508B62392C52D6DFADF67FAA9C  
  
       getUserInfo()  
   }  
     
   //失败  
   func tencentDidNotLogin(cancelled: Bool) {  
       println("登录失败了")  
   }  
     
   //无网络  
   func tencentDidNotNetWork() {  
       println("没有网络")  
   }  

4，获取用户信息

//第三步 获取用户信息  
   func getUserInfo()  
   {  
       SVProgressHUD.showWithStatus("正在获取用户信息...")  
  
       tencentOAuth.getUserInfo()  
   }  
     
     
   //第四步 在获取用户回调中获取用户信息  
   func getUserInfoResponse(response: APIResponse!) {  
         
       SVProgressHUD.dismissWithSuccess("获取用户信息成功",afterDelay: 1)  
  
       var dic:Dictionary = response.jsonResponse  
         
       println("dic:\(dic)")  
         
       //        [is_lost: 0,figureurl: http://qzapp.qlogo.cn/qzapp/222222/C5527A2F775D9EA7C20317128FAC202B/30,vip: 0,is_yellow_year_vip: 0,province: 北京,ret: 0,is_yellow_vip: 0,figureurl_qq_1: http://q.qlogo.cn/qqapp/222222/C5527A2F775D9EA7C20317128FAC202B/40,yellow_vip_level: 0,level: 0,figureurl_1: http://qzapp.qlogo.cn/qzapp/222222/C5527A2F775D9EA7C20317128FAC202B/50,city: 海淀,figureurl_2: http://qzapp.qlogo.cn/qzapp/222222/C5527A2F775D9EA7C20317128FAC202B/100,nickname: 竹中雨滴,msg:,gender: 男,figureurl_qq_2: http://q.qlogo.cn/qqapp/222222/C5527A2F775D9EA7C20317128FAC202B/100]  
         
         
       refeshUserInfo(dic)  
   }  
     
     
   //第五步 刷新用户界面  
   func refeshUserInfo(dic : NSDictionary){  
     
       let headimgurl: String = dic["figureurl_qq_2"] as! String  
       let nickname: String = dic["nickname"] as! String  
         
       self.headerImg.sd_setimageWithURL(NSURL(string: headimgurl))  
       self.nicknameLbl.text = nickname  
  
   } 

5，跳转

func application(application: UIApplication,annotation: AnyObject?) -> Bool {  
      return TencentOAuth.HandleOpenURL(url)  
  }  
    
  func application(application: UIApplication,handleOpenURL url: NSURL) -> Bool {  
      return TencentOAuth.HandleOpenURL(url)  
  }

四，微博

1，注册

2，授权登录

func sendBtnClick(sneder:UIButton)  
    {  
        sendSinaAuthRequest()  
    }  
      
    //第一步  微博登录  
    func sendSinaAuthRequest(){  
          
        var request : WBAuthorizeRequest = WBAuthorizeRequest.request() as! WBAuthorizeRequest  
        request.redirectURI = kRedirectURI  
        request.scope = "all"  
        request.userInfo = ["SSO_Key":"SSO_Value"]  
        WeiboSDK.sendRequest(request)  
    } 

3，回调

func didReceiveWeiboRequest(request: WBBaseRequest!) {  
  
    }  
      
    func didReceiveWeiboResponse(response: WBBaseResponse!) {  
    
        if response.isKindOfClass(WBAuthorizeResponse){

                println("userID:\(userID)\naccesstoken:\(accesstoken)")  
                  
                var userInfo = response.userInfo as Dictionary  
                  
                NSNotificationCenter.defaultCenter().postNotificationName("SINA_CODE",userInfo: userInfo)  
  
            }  
        }  
    }

//第二步  通过通知得到登录后获取的用户信息  
    func onRecviceSINA_CODE_Notification(notification:NSNotification)  
    {  
        SVProgressHUD.showSuccessWithStatus("获取到用户信息",duration: 1)
