背景

公司在https服務(wù)器（端口443）進(jìn)行正常登陸業(yè)務(wù)等處理
https://ip1:443/
然后在端口444服務(wù)器進(jìn)行資料文件上傳等處理
https://ip1:444/
因?yàn)榉?wù)器在https://ip1:443/登陸成功之后對cookie中的session進(jìn)行校驗(yàn)保存讲岁，而一旦出現(xiàn)訪問443->444->443，就是進(jìn)行文件上傳操作后衬以，再調(diào)用443端口后缓艳，服務(wù)器對session校驗(yàn)失敗，出現(xiàn)會話超時(shí)問題

原因

因?yàn)閟ession狀態(tài)是靠cookie中存儲的jsessionid實(shí)現(xiàn)的泄鹏，所以郎任，由于兩個服務(wù)器的sessionid秧耗，名稱备籽、域、路徑都一樣分井，導(dǎo)致sessionid被覆蓋车猬，從而導(dǎo)致session失效；由此也得出cookie是不區(qū)分端口的尺锚。

cookie不區(qū)分端口號
cookie區(qū)分域珠闰、路徑、名稱

處理辦法

在訪問另一個端口前瘫辩，把cookie緩存到本地伏嗜，然后在返回443端口后坛悉，再把cookie重新寫入

導(dǎo)出cookie并緩存:

//導(dǎo)出cookie
    NSHTTPCookieStorage* nCookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray* nCookies = [nCookies cookiesForURL:[NSURL URLWithString:urlStr]].copy;
for(NSHTTPCookie*cookie in nCookies)
    {
        if([cookie isKindOfClass:[NSHTTPCookie class]])
        {
            if([cookie.name isEqualToString:@"JSESSIONID"])
            {
                NSNumber*sessionOnly =[NSNumber numberWithBool:cookie.sessionOnly];
                NSNumber*isSecure = [NSNumber numberWithBool:cookie.isSecure];
                NSArray*cookies = [NSArray arrayWithObjects:cookie.name, cookie.value, sessionOnly, cookie.domain, cookie.path, isSecure,nil];
                [[NSUserDefaults standardUserDefaults]setObject:cookies forKey:@"cookies"];
                
                break;
            }
        }
    }

讀取cookie并寫入:

-(void)loadCookies
{
    NSArray*cookies =[[NSUserDefaults standardUserDefaults]objectForKey:@"cookies"];
    
    if(cookies.count>0)
    {
        NSMutableDictionary*cookieProperties = [NSMutableDictionary dictionary];
        [cookieProperties setObject:[cookies objectAtIndex:0]forKey:NSHTTPCookieName];
        
        [cookieProperties setObject:[cookies objectAtIndex:1]forKey:NSHTTPCookieValue];
        
        [cookieProperties setObject:[cookies objectAtIndex:3]forKey:NSHTTPCookieDomain];
        
        [cookieProperties setObject:[cookies objectAtIndex:4]forKey:NSHTTPCookiePath];
        
        NSHTTPCookie*cookieuser = [NSHTTPCookie cookieWithProperties:cookieProperties];
        
        [[NSHTTPCookieStorage sharedHTTPCookieStorage]setCookie:cookieuser];
        
    }
}

PS:AFNetworking也能用相同處理辦法
