C#调用腾讯云图片鉴黄
废话不多说 直接上代码
这里使用的是人工智能里面的智能图像--万象优图 没有用天御的（太贵了） 首先要开通智能图像的功能
注意：这里要绑定Bucket 使用主账号的appid，不是协作者的
var urlList = new List
urlList.Add(url);
//请求参数
var req = new { appid = ConfigurationManager.AppSettings["AppId"], url_list = urlList };
var psotJson = JsonConvert.SerializeObject(req);
TencentCloundPicHelper tencentHelper = new TencentCloundPicHelper();
var info = tencentHelper.SendPost(psotJson);
TencentJianHuangResponse response = JsonConvert.DeserializeObject
if (response != null && response.result_list.Any())
{
if (response.result_list.FirstOrDefault().code == 0)//成功
{
if (response.result_list.FirstOrDefault().data.result != 0)//是黄图
{
responseMessage.Message = CommonConst.PicNolegal;
responseMessage.ResultCode = "555";
responseMessage.Info = new { Url = url, TencentJson = info };
return responseMessage;
}
}
