基于Swift语言开发微信、QQ和微博的SSO授权登录代码分析

前言

Swift 语言,怎么说呢,有一种先接受后排斥。又欢迎的感觉,纵观国外大牛开源框架或项目演示,Swift差点儿占领了多半,而国内尽管出现非常多相关技术介绍和教程,可是在真正项目开发中使用的占领非常少部分。原因一是眼下熟练它的开发人员并不多,二是版本号不太稳定,还须要更成熟可靠的版本号支持,但总之未来还是非常有前景的。深有体会。无论是代码量还是编译效率。以及语言特性。现代性都优于Object-C,预计兴许会被苹果作为官方开发语言,值得期待。


走起

鉴于此,笔者将之前用Object-C写的SSO授权登录:微信,QQ和微博。又一次用Swift语言写一遍,以便须要的朋友參考。算是SSO授权登录的姊妹篇;


一,整体架构

1,引入第三方库

除了必须引入相应的登录SDK外,额外引入了SDWebImage。SVProgressHUD。看名字大家都明确吧。引入登录SDK请各自看官方的开发文档,须要增加什么系统库文件。须要配置Other Linker Flags 等,请參考各自官方文档就可以。

2,配置连接桥文件

由于创建的project是基于Swift语言,眼下官方SDK和其他三方库都是用OC写的,所以为了在swift中调用oc代码。须要配置连接桥文件Bridging-Header.h,搜索objective-C bridging Header健,然后在值里面输入XXXLogin/Bridging-Header.h,注意是绝对路径。里面能够输入须要调用的头文件。如

#import "WXApi.h"
#import "SVProgressHUD.h"
#import "UIImageView+WebCache.h"


3,配置project

由于是SSO跳转方式,须要配置URL Schemes,以便程序返回识别宿主程序。配置方法非常easy,參考各自文档就可以。在info里面能够可视化加入。各自的key值採用官方demo所提供。

二,微信

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

2,授权登录
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版本号之微信授权登录", 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, 160, 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)
    }

3,回调
 func onResp(resp: BaseResp!) {
        
        /*
        
        ErrCode	ERR_OK = 0(用户允许)
        ERR_AUTH_DENIED = -4(用户拒绝授权)
        ERR_USER_CANCEL = -2(用户取消)
        code	用户换取access_token的code,仅在ErrCode为0时有效
        state	第三方程序发送时用来标识其请求的唯一性的标志,由第三方程序调用sendReq时传入。由微信终端回传。state字符串长度不能超过1K
        lang	微信client当前语言
        country	微信用户当前国家信息
        */
        // var aresp resp :SendAuthResp!
        var aresp = resp as! SendAuthResp
        //  var aresp1 = resp as? SendAuthResp
        
        if (aresp.errCode == 0)
        {
            println(aresp.code)
            //031076fd11ebfa5d32adf46b37c75aax
            
            var dic:Dictionary<String,String>=["code":aresp.code];
            let value = dic["code"]
            println("code:\(value)")
            
            NSNotificationCenter.defaultCenter().postNotificationName("WX_CODE", object: nil, userInfo: dic)
            
        }
    }

4,获取用户信息

//微信回调通知,获取code 第二步
    
    func onRecviceWX_CODE_Notification(notification:NSNotification)
    {
        SVProgressHUD.showSuccessWithStatus("获取到code", duration: 1)
        
        var userinfoDic : Dictionary = notification.userInfo!
        let code: String = userinfoDic["code"] as! String
        
        println("Recevice Code: \(code)")
        
        self.getAccess_token(code)
    }
    
    //获取token 第三步
    func getAccess_token(code :String){
        //https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code
        
        var requestUrl = "https://api.weixin.qq.com/sns/oauth2/access_token?

appid=\(kWXAPP_ID)&secret=\(kWXAPP_SECRET)&code=\(code)&grant_type=authorization_code" dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { var requestURL: NSURL = NSURL(string: requestUrl)! var data = NSData(contentsOfURL: requestURL, options: NSDataReadingOptions(), error: nil) dispatch_async(dispatch_get_main_queue(), { var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSDictionary println("Recevice Token: \(jsonResult)") SVProgressHUD.showSuccessWithStatus("获取到Token和openid", duration: 1) let token: String = jsonResult["access_token"] as! String let openid: String = jsonResult["openid"] as! String self.getUserInfo(token, openid: openid) }) }) } //获取用户信息 第四步 func getUserInfo(token :String,openid:String){ // https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID var requestUrl = "https://api.weixin.qq.com/sns/userinfo?

access_token=\(token)&openid=\(openid)" dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), { var requestURL: NSURL = NSURL(string: requestUrl)! var data = NSData(contentsOfURL: requestURL, options: NSDataReadingOptions(), error: nil) dispatch_async(dispatch_get_main_queue(), { var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers, error: nil) as! NSDictionary println("Recevice UserInfo: \(jsonResult)") /* Recevice UserInfo: { city = Chaoyang; country = CN; headimgurl = "http://wx.qlogo.cn/mmopen/FrdAUicrPIibcpGzxuD0kjfssQogj3icL8QTJQYUCLpgzSnvY6rJFGORreicPUiaPCzojwNlsXq4ibbc8e3gGFricWqJU5ia7ibicLVhfT/0"; language = "zh_CN"; nickname = "\U706b\U9505\U6599"; openid = "oyAaTjkR8T6kcKWyA4VPYDa_Wy_w"; privilege = ( ); province = Beijing; sex = 1; unionid = "o1A_Bjg52MglJiEjhLmB8SyYfZIY"; } */ SVProgressHUD.showSuccessWithStatus("获取到用户信息", duration: 1) let headimgurl: String = jsonResult["headimgurl"] as! String let nickname: String = jsonResult["nickname"] as! String self.headerImg.sd_setImageWithURL(NSURL(string: headimgurl)) self.nicknameLbl.text = nickname }) }) }



5,跳转

 //微信的跳转回调
    func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?) -> Bool    {
        return  WXApi.handleOpenURL(url, delegate: self)
    }
  func application(application: UIApplication, handleOpenURL url: NSURL) -> Bool 
<span style="white-space:pre">	</span>{
        return  WXApi.handleOpenURL(url, delegate: self)
    }
    

三。QQ

1,注冊
    func sendBtnClick(sneder:UIButton)
    {
        sendQQAuthRequest()
    }
    
    //第一步  QQ登录
    func sendQQAuthRequest(){
        
        tencentOAuth = TencentOAuth(appId: kQQAPP_ID, andDelegate: self)
        var permissions = [kOPEN_PERMISSION_GET_INFO,kOPEN_PERMISSION_GET_USER_INFO,kOPEN_PERMISSION_GET_SIMPLE_USER_INFO]
        tencentOAuth.authorize(permissions, inSafari: false)
        
    }


2,授权登录

如上

3。回调

 //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, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?

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




四,微博

1。注冊

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.
        
        WeiboSDK.registerApp(kAppKey)
        
        return true
    }

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){

            if (response.statusCode == WeiboSDKResponseStatusCode.Success) {
            
                var authorizeResponse : WBAuthorizeResponse = response as! WBAuthorizeResponse
                var userID = authorizeResponse.userID
                var accessToken = authorizeResponse.accessToken
                
                println("userID:\(userID)\naccessToken:\(accessToken)")
                
                var userInfo = response.userInfo as Dictionary
                
                NSNotificationCenter.defaultCenter().postNotificationName("SINA_CODE", object: nil, userInfo: userInfo)

            }
        }
    }

4。获取用户信息

//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)
        
        var userinfoDic : Dictionary = notification.userInfo!
        
        println("userInfo:\(userinfoDic)")
        
        
        /*
        userID:2627289515
        accessToken:2.002BqnrCyY87OC80500cab28Ofqd3B
        userInfo:
        [uid: 2627289515, remind_in: 647057, scope: invitation_write, refresh_token: 2.002BqnrCyY87OC10f7877765yPietB,
        app: {
        logo = "http://ww1.sinaimg.cn/square/65745bf7jw1ea399us692j2028028glf.jpg";
        name = "SDK\U5fae\U535a\U5e94\U7528demo";
        }, 
        access_token: 2.002BqnrCyY87OC80500cab28Ofqd3B, expires_in: 647057
        ]
        
        */
        
        var userAppInfo: Dictionary<String,String> = userinfoDic["app"] as! Dictionary
        
        refeshUserInfo(userAppInfo)
    }

    //第三步 刷新用户界面
    func refeshUserInfo(dic : NSDictionary){
        
        let headimgurl: String = dic["logo"] as! String
        let nickname: String = dic["name"] as! String
        
        self.headerImg.sd_setImageWithURL(NSURL(string: headimgurl))
        self.nicknameLbl.text = nickname
    }


5,跳转
func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject?

) -> Bool { return WeiboSDK.handleOpenURL(url, delegate: self) } func application(application: UIApplication, handleOpenURL url: NSURL) -> Bool { return WeiboSDK.handleOpenURL(url, delegate: self) }


五,对照分析

1。demo情况

微博demo代码工整度完爆微信。QQ。看着非常舒服,心情也不错。另外微博放在了github上面。适合pod管理。凝视也极好,微信文档写的挺不错,QQ写的简直丧心病狂,须要极度耐心才干看明确,表示非常无语,另外本三种方式授权登录的源码有偿提供,如需能够邮件[email protected]联系就可以。

2,嵌入时间

微信算是非常easy嵌入SDK,QQ也还能够。微博须要注意boundID有限制。微信的逻辑算是比較冗余繁琐。从授权到获取到用户信息须要非常多接口,而QQ和微博能够直接从授权登陆回调中获取到。是比較便捷的。从上面代码能够看出来;

后记

从objective-C到Swift,苹果力求简约,但又不简单,现代化的语言,必定在性能各方面优于传统,仅仅是须要时间和很多其它的考验,作为开发人员。多一个选择,岂不更好。
