【无标题】unity人脸融合API Face++

Face++融合时融合是整体的例如你戴眼镜模板图不带眼睛融合后就是戴眼镜的融合上传的图片可以是文件流也可以是Base64

     private const string KEY = "XP9kdJPbF-4UugXEDr*********R";private const string SECRET = "T5mccUDL6GHc-gR**********";private const string URL = "https://api-cn.faceplusplus.com/imagepp/v1/mergeface";Dictionary<string, object> verifyPostParameters = new Dictionary<string, object>();verifyPostParameters.Add("api_key", KEY);verifyPostParameters.Add("api_secret", SECRET);//添加模板图片参数verifyPostParameters.Add("template_file", new HttpHelper4MultipartForm.FileParameter(Texture2DToBytes(template), "1.jpg", "application/octet-stream"));//   verifyPostParameters.Add("template_file",base64);//添加合并图片参数verifyPostParameters.Add("merge_file", new HttpHelper4MultipartForm.FileParameter(Texture2DToBytes(merget), "2.jpg", "application/octet-stream"));//   verifyPostParameters.Add(""merge_file"",base64);//添加融合比例参数merge_rate = gameManager.config.mergeRate;verifyPostParameters.Add("merge_rate", merge_rate.ToString());//添加五官融合比例feature_rate = gameManager.config.featureRate;verifyPostParameters.Add("feature_rate", feature_rate.ToString());HttpWebResponse verifyResponse = HttpHelper4MultipartForm.MultipartFormDataPost(URL, "", verifyPostParameters);using (StreamReader reader = new StreamReader(verifyResponse.GetResponseStream(), System.Text.Encoding.UTF8)){//返回值处理A a = JsonUtility.FromJson<A>(reader.ReadToEnd());Debug.Log(a.time_used);byte[] b;Texture2D temp;if (string.IsNullOrEmpty(a.result)){//如果返回的纹理是null,则使用模版纹理temp = template;Debug.Log("没有检测到人，使用模版纹理。");}else{//如果返回的纹理非null，则使用返回纹理b = Convert.FromBase64String(a.result);temp = new Texture2D(0, 0);temp.LoadImage(b);temp.Apply();Debug.Log("检测到人，使用返回纹理。");}}

中间使用了HttpHelper4MultipartForm函数
