IOS 網路請求中設定cookie

1. ASIHTTPRequest

ASIHTTPRequest 是一款極其強勁的 HTTP 訪問開源項目。讓簡單的 API 完成複雜的功能，如：非同步請求，隊列請求，GZIP
壓縮，緩衝，斷點續傳，進度跟蹤，上傳檔案，HTTP 認證。

cookie的支援

    如果 Cookie 存在的話，會把這些資訊放在 NSHTTPCookieStorage 容器中共用，並供下次使用。你可以用 [ ASIHTTPRequest setSessionCookies:nil ] ; 清空所有 Cookies。當然，你也可以取消預設的Cookie策略，而使自訂的Cookie：

-(NSMutableArray*)retrunCookies{    NSDictionary *properties = [[[NSMutableDictionary alloc] init] autorelease];    [properties setValue:[LoginViewController getLanguageType:loginInfo.lang] forKey:NSHTTPCookieValue];    [properties setValue:@"BENGGURU.GAIA.CULTURE_CODE" forKey:NSHTTPCookieName];    [properties setValue:@"" forKey:NSHTTPCookieDomain];    [properties setValue:[NSDate dateWithTimeIntervalSinceNow:60*60] forKey:NSHTTPCookieExpires];    [properties setValue:@"" forKey:NSHTTPCookiePath];    NSHTTPCookie *cookie = [[[NSHTTPCookie alloc] initWithProperties:properties] autorelease];    return [NSMutableArray arrayWithObject:cookie];

}

 [request setRequestCookies:[self retrunCookies]];                  //發送cookies,根據使用者的選擇，返回相應語言。

2.  NSMutableURLRequest(可以用於webview)

NSDictionary *properties = [[[NSMutableDictionary alloc] init] autorelease];            [properties setValue:userId forKey:NSHTTPCookieValue];            [properties setValue:@"BENQGURU.GAIA.USERID" forKey:NSHTTPCookieName];            [properties setValue:@"" forKey:NSHTTPCookieDomain];            [properties setValue:[NSDate dateWithTimeIntervalSinceNow:60*60] forKey:NSHTTPCookieExpires];            [properties setValue:@"/" forKey:NSHTTPCookiePath];            NSHTTPCookie *cookie = [[[NSHTTPCookie alloc] initWithProperties:properties] autorelease];            NSDictionary *properties1 = [[[NSMutableDictionary alloc] init] autorelease];            [properties1 setValue:[LoginViewController getLanguageType:loginInfo.lang] forKey:NSHTTPCookieValue];            [properties1 setValue:@"BENGGURU.GAIA.CULTURE_CODE" forKey:NSHTTPCookieName];            [properties1 setValue:@"" forKey:NSHTTPCookieDomain];            [properties1 setValue:[NSDate dateWithTimeIntervalSinceNow:60*60] forKey:NSHTTPCookieExpires];            [properties1 setValue:@"/" forKey:NSHTTPCookiePath];            NSHTTPCookie *cookie1 = [[[NSHTTPCookie alloc] initWithProperties:properties1] autorelease];            NSArray *cookies=[NSArray arrayWithObjects:cookie,cookie1,nil];           NSDictionary *headers=[NSHTTPCookie requestHeaderFieldsWithCookies:cookies];            NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:[object valueForKey:@"url"]]];            [request setValue:[headers objectForKey:@"Cookie"] forHTTPHeaderField:@"Cookie"];           [webView loadRequest:request];
