问题描述
我有3种方法，UserLogin，Login和LogoutButtonPressed：
I have 3 methods, UserLogin, Login and LogoutButtonPressed:
UserLogin：我正在使用AFNetworking使用NSURLCredential连接到Windows身份验证的URL：
UserLogin: I am using AFNetworking to connect to a Windows Authenticated URL using NSURLCredential:
-(void)UserLogin:(NSString *)user andPassWordExists:(NSString *)password completionHandler:(void (^)(NSArray *resultsObject, NSError *error))completionHandler
{
NSURL *url = [NSURL URLWithString:kIP];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
initWithRequest:request];
NSURLCredential *credential = [NSURLCredential
credentialWithUser:user
password:password
persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
[[NSOperationQueue mainQueue] addOperation:operation];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
if (completionHandler) {
completionHandler(responseObject, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (completionHandler) {
completionHandler(nil, error);
}
}];
[operation start];
}
此方法由Login方法调用：
This method is being called by the Login method:
- (void)Login
{
NSString *rawString = [self.idTextField text];
NSCharacterSet *whitespace = [NSCharacterSet whitespaceAndNewlineCharacterSet];
[self.idTextField setText:[rawString stringByTrimmingCharactersInSet:whitespace]];
[userName UserLogin:self.idTextField.text andPassWordExists:self.passwordTextField.text completionHandler:^(id responseObject, NSError *error) {
if (responseObject) {
[self.idTextField removeFromSuperview];
[self.passwordTextField removeFromSuperview];
[self.loginButton removeFromSuperview];
self.idTextField = nil;
self.passwordTextField = nil;
//self.loginButton = nil;
[self CreateMenu];
[indicatorView stopAnimating];
[indicatorView removeFromSuperview];
indicatorView = nil;
[loadingView removeFromSuperview];
loadingView = nil;
}else{
[self CustomAlert:@"Sorry Login Failed, User and/or Passsword Incorrect"];
[indicatorView stopAnimating];
[indicatorView removeFromSuperview];
indicatorView = nil;
[loadingView removeFromSuperview];
loadingView = nil;
}
}];
}
我正在尝试使用LogoutButtonPressed清除我的会话：
And I am trying to clear my session with the LogoutButtonPressed:
- (void)LogoutButtonPressed
{
//@TODO: Fix Logout
NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];
if ([credentialsDict count] > 0) {
NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
id urlProtectionSpace;
while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
id userNameCred;
while (userNameCred = [userNameEnumerator nextObject]) {
NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCred];
NSLog(@"cred to be removed: %@", cred);
[[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
}
}
}
}
I从这个例子中得到了这个代码：
I got this code from this example: http://www.springenwerk.com/2008/11/i-am-currently-building-iphone.html
现在我的问题是，当我触发注销按钮然后转到触发登录方法WITH NO CREDENTIALS我仍然可以登录，如果我退出然后等待2 - 3分钟并登录没有证书我无法登录。为什么它以这种方式表现，它几乎就像信用卡仍然保存。请帮助。
Now my problem I am having is that when I trigger the logout button and then goto trigger the login method WITH NO CREDENTIALS I can still login, If I logout then wait 2 - 3 minutes and login with NO CREDENTIALS I can't login. Why is it behaving this way, its almost like the creds are still saved. Please help.
更新
我试图清除缓存，Cookie和我的LogoutButtonPressed中的信用：
I have tried to clear the cache, cookies and creds inside my LogoutButtonPressed:
NSURLCache *sharedCache = [NSURLCache sharedURLCache];
[sharedCache removeAllCachedResponses];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray *cookies = [cookieStorage cookies];
id cookie;
for (cookie in cookies) {
[cookieStorage deleteCookie:cookie];
}
NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];
if ([credentialsDict count] > 0) {
NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
id urlProtectionSpace;
while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
id userNameCreds;
while (userNameCreds = [userNameEnumerator nextObject]) {
NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCreds];
[[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
}
}
}
它仍然不起作用。
我还尝试清除AuthorizationHeader和cancellingAllOperations但仍然没有，我仍然可以在注销后以错误或无信用登录：
I also tried clearing AuthorizationHeader and cancelingAllOperations and still nothing, I am still able to login with wrong or no creds after logout:
NSURLCache *sharedCache = [NSURLCache sharedURLCache];
[sharedCache removeAllCachedResponses];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSArray *cookies = [cookieStorage cookies];
id cookie;
for (cookie in cookies) {
[cookieStorage deleteCookie:cookie];
}
NSDictionary *credentialsDict = [[NSURLCredentialStorage sharedCredentialStorage] allCredentials];
if ([credentialsDict count] > 0) {
NSEnumerator *protectionSpaceEnumerator = [credentialsDict keyEnumerator];
id urlProtectionSpace;
while (urlProtectionSpace = [protectionSpaceEnumerator nextObject]) {
NSEnumerator *userNameEnumerator = [[credentialsDict objectForKey:urlProtectionSpace] keyEnumerator];
id userNameCreds;
while (userNameCreds = [userNameEnumerator nextObject]) {
NSURLCredential *cred = [[credentialsDict objectForKey:urlProtectionSpace] objectForKey:userNameCreds];
[[NSURLCredentialStorage sharedCredentialStorage] removeCredential:cred forProtectionSpace:urlProtectionSpace];
}
}
}
NSURL *url = [NSURL URLWithString:kIP];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestSerializer <AFURLRequestSerialization> * requestSerializer = manager.requestSerializer;
[requestSerializer clearAuthorizationHeader];
AFHTTPRequestOperationManager *httpClient = [[AFHTTPRequestOperationManager alloc] initWithBaseURL:url];
[[httpClient operationQueue] cancelAllOperations];
推荐答案
通过添加随机数可以轻松修复此问题到URL的末尾：
This issue can be fixed easily by adding a random number to the end of the URL:
-(void)UserLogin:(NSString *)user andPassWordExists:(NSString *)password completionHandler:(void (^)(NSArray *resultsObject, NSError *error))completionHandler
{
NSInteger randomNumber = arc4random() % 999;
NSString *requestURL = [NSString stringWithFormat:@"%@?cache=%ld",kIP,(long)randomNumber];
NSURL *url = [NSURL URLWithString:requestURL];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc]
initWithRequest:request];
NSURLCredential *credential = [NSURLCredential
credentialWithUser:user
password:password
persistence:NSURLCredentialPersistenceForSession];
[operation setCredential:credential];
operation.responseSerializer = [AFJSONResponseSerializer serializer];
[[NSOperationQueue mainQueue] addOperation:operation];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
if (completionHandler) {
completionHandler(responseObject, nil);
}
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
if (completionHandler) {
completionHandler(nil, error);
}
}];
[operation start];
}
并确保在结尾处有一个随机数字您正在呼叫的所有网址。
And make sure you have a random number at the end of all URLs you are calling.
