Failed to create cookie with "NSHTTPCookie cookieWithProperties"

Question

I use the following code to create a cookie, but with an error (iOS SDK 5)

// add cookie NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys: req.URL, NSHTTPCookieOriginURL, @"MLSTORAGE", NSHTTPCookieName, @"1234567890", NSHTTPCookieValue, nil]; NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties]; NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie); [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie]; //

Does anyone know how to create a cookie?

Answer 1

There seems to be a problem when using NSHTTPCookieOriginURL with your request url.

Try using this code, it worked for me:

 // add cookie NSDictionary *properties = [NSDictionary dictionaryWithObjectsAndKeys: req.URL.host, NSHTTPCookieDomain, req.URL.path, NSHTTPCookiePath, @"MLSTORAGE", NSHTTPCookieName, @"1234567890", NSHTTPCookieValue, nil]; NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:properties]; NSLog(@"\nurl: %@\ncookie: %@", req.URL, cookie); [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie]; // 

However, I do not know why NSHTTPCookieOriginURL does not work here.

Hope this helps,

To successfully create a cookie, you must specify values ​​for (at least) the NSHTTPCookiePath, NSHTTPCookieName, and NSHTTPCookieValue keys, as well as the NSHTTPCookieOriginURL key or the NSHTTPCookieDomain key.

This can be useful for setting an array of cookies in NSHTTPCookieStorage. I ran into this problem and I decided to use the code below. Hope this will be useful for anyone trying to set an array of cookies.

  NSDictionary *cookieProperties = [NSDictionary dictionaryWithObjectsAndKeys: @".domain.com", NSHTTPCookieDomain, @"/", NSHTTPCookiePath, @"SESSION", NSHTTPCookieName, @"Session value",NSHTTPCookieValue,nil]; NSDictionary *cookieProperties1 = [NSDictionary dictionaryWithObjectsAndKeys: @".domain.com", NSHTTPCookieDomain, @"/", NSHTTPCookiePath, @"some cookie", NSHTTPCookieName, @"some cookie value",NSHTTPCookieValue,nil]; NSHTTPCookie *cookie1 = [NSHTTPCookie cookieWithProperties:cookieProperties1]; NSHTTPCookie *cookie = [NSHTTPCookie cookieWithProperties:cookieProperties]; NSArray* cookieArray = [NSArray arrayWithObjects: cookie,cookie1, nil]; [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookies:cookieArray forURL:[NSURL URLWithString:urlString] mainDocumentURL:nil]; 

You can cross-check your cookies using the code below.

 [[[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies] enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) { NSLog(@"Printing cookies %@", obj); }];

I met the same question. When I looked through the documentation and found that the properties only require a "name", "value" and "originURL" or "domain", I tried, but could not. After I added the "path" and then it worked. Since I just did not understand that if you just provide a "domain" other than "originURL", a "path" is also required.

 <tr> <th>Property key constant</th> <th>Type of value</th> <th>Required</th> <th>Description</th> </tr> <tr> <td>NSHTTPCookieName</td> <td>NSString</td> <td>YES</td> <td>Name of the cookie</td> </tr> <tr> <td>NSHTTPCookieValue</td> <td>NSString</td> <td>YES</td> <td>Value of the cookie</td> </tr> <tr> <td>NSHTTPCookieDomain</td> <td>NSString</td> <td>Special, a value for either NSHTTPCookieOriginURL or NSHTTPCookieDomain must be specified.</td> <td>Domain for the cookie. Inferred from the value for NSHTTPCookieOriginURL if not provided.</td> </tr> <tr> <td>NSHTTPCookieOriginURL</td> <td>NSURL or NSString</td> <td>Special, a value for either NSHTTPCookieOriginURL or NSHTTPCookieDomain must be specified.</td> <td>URL that set this cookie. Used as default for other fields as noted.</td> </tr> <tr> <td>NSHTTPCookiePath</td> <td>NSString</td> <td>NO</td> <td>Path for the cookie. Inferred from the value for NSHTTPCookieOriginURL if not provided. Default is "/".</td> </tr> 

The final code is below:

 NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary]; [cookieProperties setObject:@"SESSION" forKey:NSHTTPCookieName]; [cookieProperties setObject:@"value" forKey:NSHTTPCookieValue]; [cookieProperties setObject:@".domain.com" forKey:NSHTTPCookieDomain]; [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath]; NSHTTPCookie *co = [NSHTTPCookie cookieWithProperties:cookieProperties]; [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:co];
