iOS第三方授權登入
阿新 • • 發佈：2019-02-20
廢話不多說，直接上乾貨！
以下所有的QQ授權登入都簡稱QQ登入，所有的微信授權登入簡稱微信登入
第一步：不管是QQ登入還是微信登入，先讓產品同事去開放平臺申請APP ID和APP金鑰；
第三步：新增標頭檔案
#import <TencentOpenAPI/QQApiInterface.h>
#import <TencentOpenAPI/TencentOAuth.h>
#import <WXApi.h>
#import <WechatAuthSDK.h>
第四步：開始寫ThirdLogin封裝(以下封裝主要是實現登入和獲取使用者資訊)
標頭檔案
@interface ThirdLogin : NSObject @property (nonatomic, copy) void (^QQOpenID)(NSString *qqOpenId); @property (nonatomic, copy) void (^WXOpenID)(NSString *wxOpenId); @property (nonatomic, copy) void (^QQUserInfo)(NSDictionary *qqUserInfo); @property (nonatomic, copy) void (^WXUserInfo)(NSDictionary *wxUserInfo); // 獲取模組單例 + (ThirdLogin *)shareInstance; #pragma mark - QQ登入 // 拉起QQ登入UI - (void)qqLogin; #pragma mark - 微信登入 // 註冊微信登入 - (void)wxLoginRegister; // 拉起微信登入UI - (void)wxLogin; // 獲取微信訪問令牌 - (void)getWeixinOpenId:(NSString *)code; @end
實現檔案
#import "ThirdLogin.h" @interface ThirdLogin () <QQApiInterfaceDelegate, TencentSessionDelegate, WXApiDelegate> @property (nonatomic, strong) TencentOAuth *tencentOAuth; @end @implementation ThirdLogin // 獲取模組單例 + (ThirdLogin *)shareInstance { static ThirdLogin *instance = nil; static dispatch_once_t predicate; dispatch_once(&predicate, ^{ instance = [[ThirdLogin alloc] init]; }); return instance; } #pragma mark - QQ登入 // 拉起QQ登入UI - (void)qqLogin { self.tencentOAuth = [[TencentOAuth alloc] initWithAppId:QQLOGIN_APPID andDelegate:self]; NSArray *permissions = @[kOPEN_PERMISSION_GET_USER_INFO, kOPEN_PERMISSION_GET_SIMPLE_USER_INFO, kOPEN_PERMISSION_ADD_ALBUM, kOPEN_PERMISSION_ADD_ONE_BLOG, kOPEN_PERMISSION_ADD_SHARE, kOPEN_PERMISSION_ADD_TOPIC, kOPEN_PERMISSION_CHECK_PAGE_FANS, kOPEN_PERMISSION_GET_INFO, kOPEN_PERMISSION_GET_OTHER_INFO, kOPEN_PERMISSION_LIST_ALBUM, kOPEN_PERMISSION_UPLOAD_PIC, kOPEN_PERMISSION_GET_VIP_INFO, kOPEN_PERMISSION_GET_VIP_RICH_INFO]; [self.tencentOAuth authorize:permissions]; } // 授權成功 - (void)tencentDidLogin { if (self.tencentOAuth.accessToken && self.tencentOAuth.accessToken.length > 0) { if (self.QQOpenID) { self.QQOpenID(self.tencentOAuth.openId); } // 獲取使用者資訊 [self.tencentOAuth getUserInfo]; } } // 授權失敗 - (void)tencentDidNotLogin:(BOOL)cancelled { } // 無網路 - (void)tencentDidNotNetWork { } // 獲取使用者資訊成功 - (void)getUserInfoResponse:(APIResponse *)response { if (self.QQUserInfo) { self.QQUserInfo(response.jsonResponse); } } - (void)isOnlineResponse:(NSDictionary *)response { } - (void)onReq:(QQBaseReq *)req { } - (void)onResp:(QQBaseResp *)resp { } #pragma mark - 微信登入 // 註冊微信登入 - (void)wxLoginRegister { [WXApi registerApp:WXLOGIN_APPID]; } // 拉起微信登入UI - (void)wxLogin { if ([WXApi isWXAppInstalled]) { SendAuthReq *req = [[SendAuthReq alloc] init]; req.scope = @"snsapi_userinfo"; req.state = @"XXXXXXXX"; [WXApi sendReq:req]; } else { [SVProgressHUD showErrorWithStatus:@"您的裝置未安裝微信"]; } } // 獲取微信訪問令牌 - (void)getWeixinOpenId:(NSString *)code { NSString *url = [NSString stringWithFormat:@"https://api.weixin.qq.com/sns/oauth2/access_token?appid=%@&secret=%@&code=%@&grant_type=authorization_code", WXLOGIN_APPID, WXLOGIN_APPSERECET, code]; 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]; if (self.WXOpenID) { self.WXOpenID(dic[@"openid"]); } [self requestUserInfoByToken:dic[@"access_token"] andOpenid:dic[@"openid"]]; } }); }); } // 通過令牌請求微信使用者資訊 - (void)requestUserInfoByToken:(NSString *)token andOpenid:(NSString *)openID { NSString *url = [NSString stringWithFormat:@"https://api.weixin.qq.com/sns/userinfo?access_token=%@&openid=%@", token, openID]; AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; [manager GET:url parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableContainers error:nil]; if (self.WXUserInfo) { self.WXUserInfo(dic); } } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { [SVProgressHUD showSuccessWithStatus:error.description]; }]; } @end
第五步：呼叫
QQ登入
[[ThirdLogin shareInstance] qqLogin]; [[ThirdLogin shareInstance] setQQOpenID:^(NSString * _Nonnull qqOpenId) { [SVProgressHUD showSuccessWithStatus:qqOpenId]; }]; [[ThirdLogin shareInstance] setQQUserInfo:^(NSDictionary * _Nonnull qqUserInfo) { [SVProgressHUD showSuccessWithStatus:qqUserInfo[@"nickname"]]; }];
微信登入
[[ThirdLogin shareInstance] wxLogin];
[[ThirdLogin shareInstance] setWXOpenID:^(NSString * _Nonnull wxOpenId) {
[SVProgressHUD showSuccessWithStatus:wxOpenId];
}];
[[ThirdLogin shareInstance] setWXUserInfo:^(NSDictionary * _Nonnull wxUserInfo) {
[SVProgressHUD showSuccessWithStatus:wxUserInfo[@"nickname"]];
}];
第六步：做到這裡很多人都覺得完成了，可是為什麼還是調不起來呢？
別急，程式媛姐姐告訴你，還有幾個非常重要的配置需要去做！
第七步：注意，還沒有完！進入AppDelegate
1、新增協議<QQApiInterfaceDelegate, WXApiDelegate>
2、在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中為微信登入註冊
[[ThirdLogin shareInstance] wxLoginRegister];
3、遵守協議方法- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
if ([url.absoluteString containsString:QQLOGIN_APPID]) {
[QQApiInterface handleOpenURL:url delegate:self];
return [TencentOAuth HandleOpenURL:url];
}
if ([url.absoluteString containsString:WXLOGIN_APPID]) {
return [WXApi handleOpenURL:url delegate:self];
}
return YES;
}
走到這裡QQ登入基本上算是完成了，但是微信登入還有一個坑爹的操作，微信登入必須在AppDelegate裡實現下面這個協議方法
- (void)onResp:(BaseReq *)resp {
if([resp isKindOfClass:[SendAuthResp class]]) {
SendAuthResp *authResp = (SendAuthResp *)resp;
if (![authResp.state isEqualToString:@"XXXXXXXX"]) {
[SVProgressHUD showErrorWithStatus:@"微信授權失敗"];
return;
}
switch (authResp.errCode) {
case WXSuccess:
[[ThirdLogin shareInstance] getWeixinOpenId:authResp.code];
break;
case WXErrCodeUserCancel:
[SVProgressHUD showErrorWithStatus:@"微信授權取消"];
break;
default:
[SVProgressHUD showErrorWithStatus:@"微信授權失敗"];
break;
}
}
}
大功告成！！！
寫在文末：從第一次更新之後，姐姐我就把更多的重心置於家庭，現在姐姐又復出了，以後你們會經常看到我的喲。。。
