開發評論功能時，需要在cookie中帶有token才能發送，網絡請求中添加token的方法如下：

        NSDictionary *properties =  [NSDictionary dictionaryWithObjectsAndKeys:

                                     @"token",NSHTTPCookieValue,                // token值

                                     @"sso_tk", NSHTTPCookieName,             // token名

                                     @"/", NSHTTPCookiePath,                          // 路徑

                                     @"域名" ,NSHTTPCookieDomain,            // 域

                                     nil];

        NSHTTPCookie *cookie_PD1 = [NSHTTPCookie cookieWithProperties:properties];

        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie_PD1];
