引言
上篇：前置知识 下篇：核心实现（打开app，如果 token不过期，就使用最近一次登录的token进行接口请求）
app侧退出登录处理流程
I 核心实现
1.1 Session 对象的创建
使用HSSingleton工具类实现单例，并将包含登陆token及其他有状态相关字段的userInfo对象作为单例对象的属性
HSSingletonH(Session);
HSSingletonM(Session);
+ (void)SaveUserInfo:(UserInfoModel *)userInfo{
QCTSession.shareQCTSession.userInfo = userInfo;
}
存储token信息
#pragma
+ (void)saveModelWithModel:(UserInfoModel*)userModel{
[self emptySeeionLocal];
userModel.bg_tableName = QCTUserInfoModelTableName;
BOOL isSave = [userModel bg_save];// 保存方法
if (isSave) {
NSLog(@"token保存成功:%@",userModel.mj_keyValues);
}else{
NSLog(@"token保存失败:%@",userModel.mj_keyValues);
}
}
+(void)emptySeeionLocal{
NSMutableArray *tmparr = [NSMutableArray arrayWithArray:[[self class] bg_find:QCTUserInfoModelTableName where:nil] ];
// 先删除
for (UserInfoModel *loginModel in tmparr) {
NSString *where = [NSString stringWithFormat:@"where %@=%@",bg_sqlKey(@"bg_id"),bg_sqlValue(loginModel.bg_id)];
BOOL isDelete = [UserInfoModel bg_delete:[NSString stringWithFormat:@"%@",QCTUserInfoModelTableName] where:where];
NSLog(@"删除重复数据%@:%@",isDelete?@"成功":@"失败",loginModel.mj_keyValues);
// break;
//
获取token信息
+ (instancetype)getmodel4LoginSeesion{
NSMutableArray *tmparr = [NSMutableArray arrayWithArray:[[self class] bg_find:QCTUserInfoModelTableName where:nil] ];
if(tmparr.count>0 ){
UserInfoModel *userModel = tmparr.firstObject;
// QCTSession.shareQCTSession.userInfo = userModel;
[ QCTSession SaveUserInfo:userModel];
NSLog(@"获取的token 信息%@",userModel);
return tmparr.firstObject;
}
NSLog(@"获取的token userModel.shareUserInfoModel %@",UserInfoModel.shareUserInfoModel);
//
return
1.2 保存token到UserInfoModel 对象中的时机
- 登录的时候
[ Session SaveUserInfo:userModel];
[UserInfoModel saveModelWithModel:userModel];
- app 退出的时候:applicationWillTerminate 、applicationWillResignActive
- (void)applicationWillTerminate:(UIApplication *)application {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
1.3 再次打开app的时候获取token
#pragma
- (void)initInfo{
QCTSession.shareQCTSession.tmpUserInfoModel = nil;
[UserInfoModel getmodel4LoginSeesion];// 获取会话
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[self
1.4 退出登录或者（token）失效进行信息信息清除
- 在 application :didFinishLaunchingWithOptions: 方法进行监听
weak __typeof__(self) weakSelf = self;
[[[NSNotificationCenter defaultCenter] rac_addObserverForName:kExitlogshowLoginViewNotification object:nil] subscribeNext:^(NSNotification *notification) {
NSString *tmp = @"";
if(notification.object){
tmp = notification.object;
[weakSelf.window showHUDMessage:tmp afterBlock:^(id _Nonnull sender) {
[weakSelf setupExitlogout];
}];
}else{
// tmp = @"";
- 退出登录（token过期）的处理
/**
1、移除极光的别名
2、初始化一些信息
3、清除账户信息缓存（本地数据库和内存中的token信息）
*/
- (void)setupExitlogout
{
[JPUSHService setTags:nil alias:@"" callbackSelector:@selector(tagsAliasCallback:tags:alias:) object:self];
[UserInfoModel cleanInfoWithblock:^(id sender) {
//3、登录
UserInfoModel.shareUserInfoModel.token = nil;
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication
- 清除本地数据库的token
+ (void)cleanInfoWithblock:(void (^)(id sender))block{
[[UserInfoModel shareUserInfoModel] cleanInfo];
if(block){
block(nil);
}
}
- (void)cleanInfo{
#pragma
[[self class] emptySeeionLocal];//
[self setToken:nil];
_CurrentSysUser = nil;
// _
[QCTSession shareQCTSession].tmpUserInfoModel = nil;
}
1.5 在登录界面的viewDidLoad 进行判断是否直接进入首页
- viewDidLoad 早createSubView的时候进行判断，是否直接进入首页
if(UserInfoModel.shareUserInfoModel.isLoginByToken){
[[self class] jumpHome];
return;
}
- 判断是否有token
/**
判断是否有token
*/
- (BOOL)isLoginByToken{
if(![NSStringQCTtoll isBlankString:UserInfoModel.shareUserInfoModel.token]){
return YES;
}
return NO;
}
II 注意实现
2.1 token存储区分正式环境和测试环境
- UserInfoModel 对象新增一个当前token的域名属性currentHost，用于查询判断环境
- BGFMDB如果新增字段，就需要更换一下表名
#warning
2021-01-29 17:16:10.418453+0800 Housekeeper[15013:1071895] [logging] table QCTUserInfoModelTableName0401 has no column named BG_IsreqGetCurrentSysUsering in "insert into QCTUserInfoModelTableName0401(BG_currentHost,BG_BearerToken,BG_token,BG_DictionariesEnum,BG_DictionariesEnumDictionary,BG_loginCode,BG_isGotoChangePassword,BG_HaveDefaultLevel,BG_bg_updateTime,BG_loginMessage,BG_IsreqGetCurrentSysUsering,BG_IsTobacco,BG_bg_createTime,BG_MsgsourceStr,BG_isShowBindingMobileNote) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?);"
- 根据域名进行存取token的
NSString* where = [NSString stringWithFormat:@"where %@=%@",bg_sqlKey(@"currentHost"),bg_sqlValue(currentHost)];
NSMutableArray *tmparr = [NSMutableArray arrayWithArray:[[self class] bg_find:QCTUserInfoModelTableName where:where] ];
存储token信息
+ (void)saveModelWithModel:(UserInfoModel*)userModel{
[self emptySeeionLocal];
userModel.bg_tableName = QCTUserInfoModelTableName;
userModel.currentHost = currentHost;
BOOL isSave = [userModel bg_save];// 保存方法
if (isSave) {
NSLog(@"token保存成功:%@",userModel.mj_keyValues);
}else{
NSLog(@"token保存失败:%@",userModel.mj_keyValues);
}
}
2.2 数据存储
-
2020-03-30 19:23:12.877204+0800 Housekeeper[5577:1118700] DB Error: 1 "duplicate column name: BG_CompanyId" BGFMDB 不支持大小写，因此保存的对象不能有大小写的两个字段
@property (copy, nonatomic) NSString *companyId;
//@property (strong, nonatomic) NSString *CompanyId;
-
2020-04-01 16:18:32.127564+0800 retail[8875:1402725] [logging] table QCTUserInfoModelTableName has no column named BG_currentHost
调试技巧
如果BGFMDB的表新增字段，可更换一下表名,避免找不到字段，数据更新失败
如果新增字段，就需要更换一下表名
2.3 退出登录时清理相关的数据
// 3. 退出登录时清理消息推送的订单相关的打印数据
[ERPPrintInfo bg_clearAsync:QCTSNPrinterInfoTableName4push complete:^(BOOL

- 单点登录（Single Sign On）:简称为 SSO，是在多个应用系统中，用户只需登录一次就可以访问所有相互信任的应用系统。
例如飞书app支持的SSO
当团队的超级管理员开通此功能并在管理后台完成配置后，团队用户即可在登录时选择SSO，使用企业域名直接登录飞书。此功能适用于团队用户，不适用于个人用户。
