iOS微信第三方登錄實(shí)例
本文實(shí)例為大家分享了iOS微信第三方登錄,供大家參考,具體內(nèi)容如下
一、準(zhǔn)備工作
1、到微信開放平臺(tái)注冊(cè)成開發(fā)者,獲取appid
2、導(dǎo)入WeChatConnection.framework
3、配置URL Schemes 輸入appid 例如wx29ce0f21ea982cb8
二、配置AppDelegate.m
1、 注冊(cè)微信
//微信登陸 [WXApi registerApp:WeiXin_AppId withDescription:@"weixin"];
2、設(shè)置函數(shù)
//把代理設(shè)置到登陸視圖中 - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { return [WXApi handleOpenURL:url delegate:[LoginViewController shareLogin]]; }
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [WXApi handleOpenURL:url delegate:[LoginViewController shareLogin]]; }
三、登陸頁代碼
1、微信登錄授權(quán)比較復(fù)雜,相比QQ,新浪多了幾步,簡單說就是需要三步,第一步,獲取code,這個(gè)用來獲取token,第二步,就是帶上code獲取token,第三步,根據(jù)第二步獲取的token和openid來獲取用戶的相關(guān)信息
2、
第一步:獲取code
-(void)weiXinLogin { SendAuthReq* req =[[SendAuthReq alloc] init]; req.scope = @"snsapi_userinfo,snsapi_base"; req.state = @"0744" ; [WXApi sendReq:req]; } -(void)onReq:(BaseReq *)req { NSLog(@"呵呵"); [self msgHint:@"登陸失敗"]; } -(void)onResp:(BaseResp *)resp { SendAuthResp* sender = (SendAuthResp*)resp; NSString* code = sender.code; NSLog(@"啦啦 code = %@",code); MBProgressHUD * hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.labelText = @"收取用戶信息.."; [self getAccess_tokenWithCode:code]; }
第二步 獲取token
-(void)getAccess_tokenWithCode:(NSString*)myCode { //https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code",kWXAPP_ID,kWXAPP_SECRET,myCode]; dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ NSURL *zoneUrl = [NSURL URLWithString:url]; NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil]; NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding]; dispatch_async(dispatch_get_main_queue(), ^{ if (data) { NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]; NSString* token = [dic objectForKey:@"access_token"]; NSString* openid = [dic objectForKey:@"openid"]; [self getUserInfoWithToken:token openId:openid]; NSLog(@"token = %@",token); NSLog(@"openid = %@",openid); } }); }); }
第三步:獲取用戶信息
-(void)getUserInfoWithToken:(NSString*)myToken openId:(NSString*)myOpenId { // https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID NSString *url =[NSString stringWithFormat:@"https://api.weixin.qq.com/sns/userinfo?access_token=%@&openid=%@",myToken,myOpenId]; NSLog(@"infoUrl = %@",url); dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{ NSURL *zoneUrl = [NSURL URLWithString:url]; NSString *zoneStr = [NSString stringWithContentsOfURL:zoneUrl encoding:NSUTF8StringEncoding error:nil]; NSData *data = [zoneStr dataUsingEncoding:NSUTF8StringEncoding]; dispatch_async(dispatch_get_main_queue(), ^{ if (data) { NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil]; NSString* nickName = [dic objectForKey:@"nickname"]; NSString* wxHeadImgUrl = [dic objectForKey:@"headimgurl"]; NSLog(@"nickName = %@",nickName); NSLog(@"headImg = %@",wxHeadImgUrl); NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setObject:ON forKey:LogState]; [userDefaults setObject:ThirdFoudationLogin forKey:LogType]; [userDefaults setObject:nickName forKey:LoginName]; [userDefaults setObject:wxHeadImgUrl forKey:UserHeaderPath]; [userDefaults synchronize]; [MBProgressHUD hideAllHUDsForView:self.view animated:YES]; [self msgHint:@"微信登陸成功"]; [self popView]; } }); }); }
以上就是本文的全部內(nèi)容,希望對(duì)大家的學(xué)習(xí)有所幫助,也希望大家多多支持腳本之家。
