基于Swift语言开发微信、QQ和微博的SSO授权登录代码分析

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,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)
