iOS 实现苹果第三方登录注意事项

1.引入framework

AuthenticationServices.framework

2.添加能力

Sign in with Apple

3.代码部分 object c 实现

#import 
#import @class RootViewController;@interface AppController : NSObject <UIApplicationDelegate, ASAuthorizationControllerDelegate, ASAuthorizationControllerPresentationContextProviding>
{}@property(nonatomic, readonly) RootViewController* viewController;+ (AppController*)ins;
+ (void)setIns:(AppController*)ins;@end

static AppController* _ins;+ (AppController*)ins {return _ins;
}+ (void)setIns:(AppController*)ins {_ins = ins;
}+ (void)loginApple {NSLog(@"ios登陆开始");ASAuthorizationAppleIDProvider *provider = [[ASAuthorizationAppleIDProvider alloc] init];ASAuthorizationAppleIDRequest *request = [provider createRequest];request.requestedScopes = @[ASAuthorizationScopeFullName, ASAuthorizationScopeEmail];ASAuthorizationController *vc = [[ASAuthorizationController alloc] initWithAuthorizationRequests:@[request]];vc.delegate = [AppController ins];vc.presentationContextProvider = [AppController ins];[vc performRequests];
}- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithAuthorization:(ASAuthorization *)authorization NS_SWIFT_NAME(authorizationController(controller:didCompleteWithAuthorization:)) API_AVAILABLE(ios(13.0)) {if ([authorization.credential isKindOfClass:[ASAuthorizationAppleIDCredential class]]) {ASAuthorizationAppleIDCredential *credential = authorization.credential;NSLog(@"credential = %@", credential);NSString *state = credential.state;NSString *userID = credential.user;NSPersonNameComponents *fullName = credential.fullName;NSString *email = credential.email;NSString *authorizationCode = [[NSString alloc] initWithData:credential.authorizationCode encoding:NSUTF8StringEncoding]; // 验证 tokenNSString *identityToken = [[NSString alloc] initWithData:credential.identityToken encoding:NSUTF8StringEncoding]; // 用户 tokenASUserDetectionStatus realUserStatus = credential.realUserStatus;NSArray *authorizedScopes = credential.authorizedScopes;NSLog(@"ios登陆成功 state: %@\nuserID: %@\nfullName: %@\nemail: %@\nauthorizationCode: %@\nidentityToken: %@\nrealUserStatus: %@\nauthorizedScopes: %@",state,userID,fullName,email,authorizationCode,identityToken,@(realUserStatus),authorizedScopes);}
}- (void)authorizationController:(ASAuthorizationController *)controller didCompleteWithError:(NSError *)error  NS_SWIFT_NAME(authorizationController(controller:didCompleteWithError:)) API_AVAILABLE(ios(13.0)) {NSString *errorMsg = nil;switch (error.code) {case ASAuthorizationErrorCanceled:errorMsg = @"用户取消了授权请求";break;case ASAuthorizationErrorFailed:errorMsg = @"授权请求失败";break;case ASAuthorizationErrorInvalidResponse:errorMsg = @"授权请求响应无效";break;case ASAuthorizationErrorNotHandled:errorMsg = @"未能处理授权请求";break;case ASAuthorizationErrorUnknown:errorMsg = @"授权请求失败未知原因";break;}NSLog(@"ios登陆错误 error %@", errorMsg);
}- (ASPresentationAnchor)presentationAnchorForAuthorizationController:(ASAuthorizationController *)controller API_AVAILABLE(ios(13.0)) {return self.window;
}

4.后段验证

苹果验证接口：https://appleid.apple.com/auth/token
必传参数
client_id：app的 bundle identifier
code：手机端获取到的 authorizationCode
grant_type：传入固定字符串 authorization_code
client_secret：秘钥

秘钥client_secret的生成
ruby代码如下 gen.rb

require "jwt"key_file = "Path to the private key"
team_id = "Your Team ID"
client_id = "Your App Bundle ID"
key_id = "The Key ID of the private key"
validity_period = 180 # In days. Max 180 (6 months) according to Apple docs.private_key = OpenSSL::PKey::EC.new IO.read key_filetoken = JWT.encode({iss: team_id,iat: Time.now.to_i,exp: Time.now.to_i + 86400 * validity_period,aud: "https://appleid.apple.com",sub: client_id},private_key,"ES256",header_fields={kid: key_id }
)
puts token

key_file：苹果开发者中心下载的.p8文件保存的路径
team_id：开发者账号的teamID
client_id：项目的bundleID
key_id：苹果开发者中心创建的keyID

ruby jwt 安装 gem install jwt
如何运行这个文件，ruby gen.rb

后段验证，需要在开发这账号中添加key，勾选Sign in with Apple，

在配置中选择Apple ID

点击下载，获取.p8文件，保存Key ID
