iphone开发 cookie处理

You can use the NSURLConnection class to perform a HTTP request to login the website, and retrieve the cookie. To perform a request, just create an instance of NSURLConnection and assign a delegate object to it.

1 NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
2 NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];

Then, implement a delegate method.

1 - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
2 {
3     NSHTTPURLResponse *HTTPResponse = (NSHTTPURLResponse *)response;
4     NSDictionary *fields = [HTTPResponse allHeaderFields];
5     NSString *cookie = [fields valueForKey:"Set-Cookie"]; // It is your cookie
6 }

Retain or copy the cookie string. When you want to perform another request, add it to your HTTP header of your NSURLRequest instance.

1 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com/"]];
2 [request addValue:cookie forHTTPHeaderField:"Cookie"];

ps：

You don't need to do this, NSURLConnection automatically stores and sends cookies unless you explicitly tell it not to. – benzado Apr 20 '10 at 15:33
Even though this shouldn't be necessary fixed a suspected bug in iOS 4.2GM – crackity_jones Nov 12 '10 at 0:09

代码调试通过，具体可以参看Xcode Document

-(void)writeCookie{

    NSArray *keys = [NSArray arrayWithObjects:

                     NSHTTPCookieSecure,

                     NSHTTPCookieDomain,

                     NSHTTPCookieExpires,

                     NSHTTPCookieName,

                     NSHTTPCookiePath,

                     NSHTTPCookieValue,nil];

    NSArray *objects = [NSArray arrayWithObjects:

                        @"TRUE",

                        @".202.153.106.234",

                       nil,       //[[NSDate date] initWithTimeIntervalSinceNow:86500],

                        @"SPM_auth",

                        @"/spwebapi/",

                        @"FeiXiaoLin",nil];

    NSDictionary *dict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSHTTPCookie *cookieA = [NSHTTPCookie cookieWithProperties:dict];

    NSHTTPCookieStorage *sharedHTTPCookie = [NSHTTPCookieStorage sharedHTTPCookieStorage];

    [sharedHTTPCookie setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

     [sharedHTTPCookie setCookie:cookieA];

    NSLog(@"写入后:%@",[[NSHTTPCookieStorage sharedHTTPCookieStorage]cookies]);

 }





 -(void)readCookie {

    //    NSHTTPCookie *cookieB;

    //    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

       NSLog(@"cookies:%@",[[NSHTTPCookieStorage sharedHTTPCookieStorage]cookies]);

 }
