iOS微信第三方登录实例
本文实例为大家分享了iOS微信第三方登录，供大家参考，具体内容如下
一、准备工作
1、到微信开放平台注册成开发者，获取appid
2、导入WeChatConnection.framework
3、配置URLSchemes 输入appid 例如wx29ce0f21ea982cb8
二、配置AppDelegate.m
1、注册微信
//微信登陆 [WXApiregisterApp:WeiXin_AppIdwithDescription:@"weixin"];
2、设置函数
//把代理设置到登陆视图中
-(BOOL)application:(UIApplication*)application
handleOpenURL:(NSURL*)url
{
return[WXApihandleOpenURL:urldelegate:[LoginViewControllershareLogin]];
}
-(BOOL)application:(UIApplication*)application
openURL:(NSURL*)url
sourceApplication:(NSString*)sourceApplication
annotation:(id)annotation
{
return[WXApihandleOpenURL:urldelegate:[LoginViewControllershareLogin]];
}
三、登陆页代码
1、微信登录授权比较复杂，相比QQ，新浪多了几步，简单说就是需要三步，第一步，获取code，这个用来获取token，第二步，就是带上code获取token，第三步，根据第二步获取的token和openid来获取用户的相关信息
2、
第一步：获取code
-(void)weiXinLogin
{
SendAuthReq*req=[[SendAuthReqalloc]init];
req.scope=@"snsapi_userinfo,snsapi_base";
req.state=@"0744";
[WXApisendReq:req];
}
-(void)onReq:(BaseReq*)req
{
NSLog(@"呵呵");
[selfmsgHint:@"登陆失败"];
}
-(void)onResp:(BaseResp*)resp
{
SendAuthResp*sender=(SendAuthResp*)resp;
NSString*code=sender.code;
NSLog(@"啦啦code=%@",code);
MBProgressHUD*hud=[MBProgressHUDshowHUDAddedTo:self.viewanimated:YES];
hud.labelText=@"收取用户信息..";
[selfgetAccess_tokenWithCode:code];
}
第二步获取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=[NSStringstringWithFormat:@"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=[NSURLURLWithString:url];
NSString*zoneStr=[NSStringstringWithContentsOfURL:zoneUrlencoding:NSUTF8StringEncodingerror:nil];
NSData*data=[zoneStrdataUsingEncoding:NSUTF8StringEncoding];
dispatch_async(dispatch_get_main_queue(),^{
if(data){
NSDictionary*dic=[NSJSONSerializationJSONObjectWithData:dataoptions:NSJSONReadingMutableContainerserror:nil];
NSString*token=[dicobjectForKey:@"access_token"];
NSString*openid=[dicobjectForKey:@"openid"];
[selfgetUserInfoWithToken:tokenopenId:openid];
NSLog(@"token=%@",token);
NSLog(@"openid=%@",openid);
}
});
});
}
第三步：获取用户信息
-(void)getUserInfoWithToken:(NSString*)myTokenopenId:(NSString*)myOpenId
{
//https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID
NSString*url=[NSStringstringWithFormat:@"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=[NSURLURLWithString:url];
NSString*zoneStr=[NSStringstringWithContentsOfURL:zoneUrlencoding:NSUTF8StringEncodingerror:nil];
NSData*data=[zoneStrdataUsingEncoding:NSUTF8StringEncoding];
dispatch_async(dispatch_get_main_queue(),^{
if(data){
NSDictionary*dic=[NSJSONSerializationJSONObjectWithData:dataoptions:NSJSONReadingMutableContainerserror:nil];
NSString*nickName=[dicobjectForKey:@"nickname"];
NSString*wxHeadImgUrl=[dicobjectForKey:@"headimgurl"];
NSLog(@"nickName=%@",nickName);
NSLog(@"headImg=%@",wxHeadImgUrl);
NSUserDefaults*userDefaults=[NSUserDefaultsstandardUserDefaults];
[userDefaultssetObject:ONforKey:LogState];
[userDefaultssetObject:ThirdFoudationLoginforKey:LogType];
[userDefaultssetObject:nickNameforKey:LoginName];
[userDefaultssetObject:wxHeadImgUrlforKey:UserHeaderPath];
[userDefaultssynchronize];
[MBProgressHUDhideAllHUDsForView:self.viewanimated:YES];
[selfmsgHint:@"微信登陆成功"];
[selfpopView];
}
});
});
}
