用户登录流程
登录页面.png
点击登录按钮，最终调用的Http请求为
- (void)request_Login_WithUserName:(NSString *)username andPassWord:(NSString *)password andFid:(NSString *)fid andQuestionid:(NSString *)questionid andAnswer:(NSString *)answer andBlock:(void (^)(UserModel *data, NSError *error,NSString *message))block
{
NSDictionary *dic = @{@"version":@"1",@"module":@"login",@"loginsubmit":@"yes",@"infloat":@"yes",@"lssubmit":@"yes",@"inajax":@"1",@"fastloginfield":@"username",@"username":username,@"password":password,@"cookietime":@"259200000",@"quickforward":@"yes",@"handlekey":@"ls",@"questionid":avoidNullStr(questionid),@"answer":avoidNullStr(answer)};
[[ClanNetAPI sharedJsonClient] requestJsonDataWithPath:_kurl_base_path withParams:dic withMethodType:Get andBlock:^(id data, NSError *error)
{
if (error) {
block(nil,error,nil);
}else{
id resultData = [data valueForKeyPath:@"Variables"];
DLog(@"%@",data);
if ([resultData objectForKey:@"auth"] && ![[resultData objectForKey:@"auth"] isEqual:[NSNull null]]) {
[ClanNetAPI saveCookieData];
[[NSUserDefaults standardUserDefaults] setObject:username forKey:@"kLASTUSERNAME"];
UserModel *user = [UserModel currentUserInfo];
[user setValueWithObject:[UserModel objectWithKeyValues:data[@"data"]]];
//设置登录成功
user.logined = YES;
[UserModel saveToLocal];
if (fid) {
[self request_checkPostWithFid:fid];
}
block(user, nil,nil);
}else{
NSDictionary *errMes = data[@"Message"];
NSString *messStr = @"密码错误，请重试";
if (errMes) {
messStr = errMes[@"messagestr"];
}
//密码错误
block(nil,nil,messStr);
}
}
}];
}
- basePath: api/mobile/iyz_index.php
- Params:
NSDictionary *dic = @{
@"version":@"1",
@"module":@"login",
@"loginsubmit":@"yes",
@"infloat":@"yes",
@"lssubmit":@"yes",
@"inajax":@"1",
@"fastloginfield":@"username",
@"username":username,
@"password":password,
@"cookietime":@"259200000",
@"quickforward":@"yes",
@"handlekey":@"ls",@"questionid":avoidNullStr(questionid),
@"answer":avoidNullStr(answer)
};
在plugin/bigapp/api/1中可以找到定义的login.php模块，最终调用的登录函数为：
$result = userlogin($userName, $password, $questionid, $answer, 'username', $_G['clientip']);
我们可以在source/function/function_member.php中找到对应的函数原型。（有可能不对？）
暂时不清楚这两个文件是如何关联的。
- returnValue：
{
Message = {
messagestr = "\U767b\U5f55\U6210\U529f";
messageval = "login_succeed";
};
Variables = {
auth = "in order to be comapatible";
};
data = {
accessmasks = 0;
adminid = 0;
allowadmincp = 0;
avatarstatus = 0;
conisbind = 0;
email = "[email protected]";
emailstatus = 0;
extgroupids = "";
freeze = 0;
groupexpiry = 0;
groupid = 10;
newpm = 0;
newprompt = 0;
notifysound = 0;
onlyacceptfriendpm = 0;
regdate = 1495353072;
status = 0;
timeoffset = 9999;
uid = 2;
username = Test;
videophotostatus = 0;
};
"error_code" = 0;
"error_msg" = "\U767b\U5f55\U6210\U529f";
}
data是返回的用户信息，来自主用户表

用户如果保存在iOS应用本地
if ([resultData objectForKey:@"auth"] && ![[resultData objectForKey:@"auth"] isEqual:[NSNull null]]) {
[ClanNetAPI saveCookieData];
[[NSUserDefaults standardUserDefaults] setObject:username forKey:@"kLASTUSERNAME"];
UserModel *user = [UserModel currentUserInfo];
[user setValueWithObject:[UserModel objectWithKeyValues:data[@"data"]]];
//设置登录成功
user.logined = YES;
[UserModel saveToLocal];
if (fid) {
[self request_checkPostWithFid:fid];
}
block(user, nil,nil);
}
可以看到的是，如果用户登录成功，所做的步骤：
- 保存cookies到NSUserDefaults的Code_CookieData键值
NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject: [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies]];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: cookiesData forKey: Code_CookieData];
[defaults synchronize];
- 保存用户名到NSUserDefaults的@"kLASTUSERNAME"键值
- 将data的内容更新到单例UserModel中，并设置登录状态为YES，最后保存单例的内容。（保存到NSUserDefaults的kKEY_CURRENT_USER键值）
- 验证发帖权限 （Todo，low priority？）
再次打开APP时，用户会直接登录：
直接读取了单例UserModel的内容以及NSUserDefaults的Code_CookieData键值中保存的Cookies
用户退出登录：
- (void)logout
{
[ShareSDK cancelAuthorize:SSDKPlatformTypeSinaWeibo];
[ShareSDK cancelAuthorize:SSDKPlatformTypeWechat];
[ClanNetAPI removeCookieData];
UserModel *user = [UserModel new];
NSArray *properties = [UserModel propertiesForClass:[user class]];
for (NSString *property in properties) {
id value = [user valueForKey:property];
SEL sel = NSSelectorFromString(property);
if ([self respondsToSelector:sel]) {
[self setValue:value forKey:property];
}
}
[UserModel saveToLocal];
[UserModel currentUserInfo].logined = NO;
[UserModel saveToLocal];
//清除信息
[[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithInt:0] forKey:@"KNEWS_MESSAGE"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"KNEWS_MESSAGE_COME" object:nil];
[[NSUserDefaults standardUserDefaults] setObject:@"0" forKey:@"KNEWS_FRIEND_MESSAGE"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"KNEWS_FRIEND_MESSAGE" object:nil];
[[NSUserDefaults standardUserDefaults] setObject:nil forKey:ClanFormhash];
}
- 移除QQ，微信的认证
- 删除NSUserDefaults的Code_CookieData键值中保存的Cookies
- 重置UserModel，并设置为退出登录状态
- 移除其他信息 （Todo）
