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几乎占据了多半,而国内虽然出现很多相关技术介绍和教程,但是在真正项目开发中使用的占据很少部分,原因一是目前熟练它的开发者并不多,二是版本不太稳定,还需要更成熟可靠的版本支持,但总之未来还是很有前景的,深有体会,不管是代码量还是编译效率,以及语言特性,现代性都优于Object-C,估计后续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,重新用Swift语言写一遍,以便需要的朋友参考,算是SSO授权登录的姊妹篇;
一,总体架构
1,引入第三方库
除了必须引入对应的登录SDK外,额外引入了SDWebImage,SVProgressHUD,看名字大家都明白吧,引入登录SDK请各自看官方的开发文档,需要加入什么系统库文件,需要配置Other Linker Flags 等,请参考各自官方文档即可;
2,配置连接桥文件
因为创建的工程是基于Swift语言,目前官方SDK和其它三方库都是用OC写的,所以为了在swift中调用oc代码,需要配置连接桥文件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,里面可以输入需要调用的头文件,如
#import "WXApi.h" #import "SVProgressHUD.h" #import "UIImageView+WebCache.h"
3,配置工程
因为是SSO跳转方式,需要配置URL Schemes,以便程序返回识别宿主程序,配置方法很简单,参考各自文档即可,在info里面可以可视化添加,各自的key值采用官方demo所提供;
二,微信
1,注册
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
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, 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(用户同意) 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 微信客户端当前语言 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,注册
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) }

四,微博
1,注册
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

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,对比分析
1,demo情况
微博demo代码工整度完爆微信,QQ,看着很舒服,心情也不错;另外微博放在了github上面,适合pod管理,注释也极好,微信文档写的挺不错,QQ写的简直丧心病狂,需要极度耐心才能看明白,表示很无语,另外本三种方式授权登录的源代码有偿提供,如需可以邮件[email protected]即可;
2,嵌入时间
微信算是很容易嵌入SDK,QQ也还可以,微博需要注意boundID有限制,微信的逻辑算是比较冗余繁琐,从授权到获取到用户信息需要很多接口,而QQ和微博可以直接从授权登陆回调中获取到,是比较便捷的,从上面代码可以看出来;
后记
从objective-C到Swift,苹果力求简约,但又不简单,现代化的语言,必然在性能各方面优于传统,只是需要时间和更多的考验,作为开发者,多一个选择,岂不更好!
