调用方法
http=[httpsClassnew];
NSString *postPram = [NSStringstringWithFormat:@"requestData={\"api_Channel\":\"3\",\"api_name\":\"api.news.find_article_weekly_daily_news_list\",\"params\":{\"type\":%d,\"pageNo\":%d,\"pageSize\":%d}}",1,1,10];
NSLog(@"%@",[httpinitWithUrl:@"https://**.**.**.**/api/x.htm"postData:postPram]);
就会打印你需要的返回值。
