IOS 网络请求中设置cookie

1. ASIHTTPRequest

ASIHTTPRequest 是一款极其强劲的 HTTP 访问开源项目。让简单的 API 完成复杂的功能，如：异步请求，队列请求，GZIP 压缩，缓存，断点续传，进度跟踪，上传文件，HTTP 认证。

cookie的支持

    如果 Cookie 存在的话，会把这些信息放在 NSHTTPCookieStorage 容器中共享，并供下次使用。你可以用 [ ASIHTTPRequest setSessionCookies:nil ] ; 清空所有 Cookies。当然，你也可以取消默认的Cookie策略，而使自定义的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]];                  //发送cookies,根据用户的选择，返回相应语言。

2.  NSMutableURLRequest(可以用于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];
