OC设置cookie

移动端接入H5类型的业务常常需要给H5网页传递一些公共信息，如登录的用户信息，常用的解决方案就是通过cookie共享（有安全需要的话需加密）

//cookie设置

+ (void)setUserAndCookieWithRequest:(NSMutableURLRequest *)request

{

    if(![UserInfoModel defaultUser] && request.URL.host.length>0)    {

        NSString *userInfo = [UserInfoModel defaultUser];

        NSMutableDictionary * cookieProperties = [NSMutableDictionary dictionary];

        [cookieProperties setObject:@"userInfo" forKey:NSHTTPCookieName];

        [cookieProperties setObject:userInfo forKey:NSHTTPCookieValue];

        [cookieProperties setObject:request.URL.host forKey:NSHTTPCookieDomain];

        [cookieProperties setObject:request.URL.host forKey:NSHTTPCookieOriginURL];

        [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];

        [cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

//初始化cookie

        NSHTTPCookie * cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];

//添加cookie到NSHTTPCookieStorage中

        [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

//设置cookie到请求头

        NSArray * cookies = @[cookie];

        NSDictionary * cookieHeaderDic = [NSHTTPCookie requestHeaderFieldsWithCookies:cookies];

        [request setValue:[cookieHeaderDic objectForKey:@"Cookie"] forHTTPHeaderField:@"Cookie"];

    }
