一、微信登录
1.根据微信Api文档，导入需要的库
2.在AppDelegate初始化
[WXApi registerApp:@"appId" withDescription:@"Description"];
3.在需要授权登录的事件中，发送信息给微信
//构造SendAuthReq结构体
if([WXApi isWXAppInstalled]){//判断是否安装了客户端
SendAuthReq* req =[[SendAuthReq alloc] init];
req.scope = @"snsapi_userinfo";//一般都填写snsapi_userinfo
req.state = @"wexchat" ;//自定义
[WXApi sendReq:req];
}
4.发送成功后，微信会在- (void)onResp:(BaseResp *)resp方法中回调信息
- (void)onResp:(BaseResp *)resp {
if ([resp isKindOfClass:[SendAuthResp class]]){
SendAuthResp *authResp = (SendAuthResp *)rest;
if(authResp.errCode==0){//授权成功
[self login:authResp.code];
}
}
}
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）
5.成功后，在成功方法中根据返回的code获取Token和openID
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/html", nil];
NSString *refreshUrlStr = [NSString stringWithFormat:@"%@/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code",WX_BASE_URL, wxAppId, wxSecret,authResp.code];
[manager GET:refreshUrlStr parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"请求reAccess的response = %@", responseObject);
NSDictionary *accessDict = [NSDictionary dictionaryWithDictionary:responseObject];
NSString *accessToken = [accessDict objectForKey:WX_ACCESS_TOKEN];
NSString *openID = [accessDict objectForKey:WX_OPEN_ID];
NSString *refreshToken = [accessDict objectForKey:WX_REFRESH_TOKEN];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"用refresh_token来更新accessToken时出错 = %@", error);
}];
6.最后根据Token 和 openId获取到用户的信息
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/html", nil];
NSString *url = [NSString stringWithFormat:@"%@/userinfo?access_token=%@&openid=%@",WX_BASE_URL,access_token,openid];
[manager GET:url parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"请求用户信息 = %@", responseObject);
NSDictionary *refreshDict = [NSDictionary dictionaryWithDictionary:responseObject];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"获取用户信息失败 = %@", error);
}];
二、QQ登录(http://wiki.connect.qq.com/sdk下载)
1.根据文档导入库，如果是基础功能，只需导入基础包
identifier:tencentopenapi url Schemes:tencent+appid
到这里只是打开qq网页登录界面，如果要打开跳转到客户端，必须在info添加
LSApplicationQueriesSchemes
mqqapi
mqq
mqqOpensdkSSoLogin
mqqconnect
mqqopensdkdataline
mqqopensdkgrouptribeshare
mqqopensdkfriend
mqqopensdkapi
mqqopensdkapiV2
mqqopensdkapiV3
mqzoneopensdk
mqqopensdkapiV3
mqqopensdkapiV3
mqzone
mqzonev2
mqzoneshare
wtloginqzone
mqzonewx
mqzoneopensdkapiV2
mqzoneopensdkapi19
mqzoneopensdkapi
mqzoneopensdk
2.在需要授权登录的事件中，发送信息给Tencent
if([TencentOAuth iphoneQQInstalled]){//判断是否安装了客户端
TencentOAuth *tencentOAuth= [[TencentOAuth alloc]initWithAppId:qqAppId andDelegate:self]; //delegate必须实现
NSArray *permissions= @[@"get_user_info",@"get_simple_userinfo",@"add_t"];
[tencentOAuth authorize:permissions localAppId:qqAppId inSafari:NO];
}
实现TencentSessionDelegate
//授权成功
-(void)tencentDidLogin{
if (tencentOAuth.accessToken.length!=0)
{
// 记录登录用户的OpenID、Token以及过期时间
kNSLog(@"Tencent用户授权成功,Token=%@,openId=%@",tencentOAuth.accessToken,tencentOAuth.openId);
}
else
{
kNSLog(@"Tencent授权失败");
}
}
//非网络错误导致登录失败：
-(void)tencentDidNotLogin:(BOOL)cancelled{
if (cancelled){
NSLog(@"Tencent用户取消登录");
}else{
NSLog(@"Tencent用户登录失败");
}
}
// 网络错误导致登录失败：
-(void)tencentDidNotNetWork
{
NSLog(@"tencentDidNotNetWork");
}
