先看一個演示圖片(圖片不是靜止哦只是慢)

如何接入人臉融合功能到小程序

創建一個AI應用

https://ai.qq.com/cgi-bin/con... 登錄騰訊AI，創建并勾選相關接口即可。

記得復制APPID APPKEY
使用Java接入該功能

創建一個SpringMVC工程，包含上傳相關jar。或者SpringBoot工程也行。鄙人后端還在完善并沒有完全開源。具體可以參考https://gitee.com/xshuai/xai 項目

Java調用騰訊AI接口。小帥丶已經封裝成SDK。也是開源的 https://gitee.com/xshuai/taip

如果使用maven搭建。直接pom引入即可哦

FaceMergeController（后端處理代碼）

                String apiPtuResult = aipPtu.faceMerge(image,Integer.parseInt(model));
                PrintUtil.printJson(this.response, apiPtuResult);

                result = "{"result", "FAIL","msg":"服務器開小差了"}";
                PrintUtil.printJson(this.response, result);
              }
            }
        }
}

BaseController(基類)

import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.bind.annotation.ModelAttribute;
/**
 * 基類Controller 
 * 一些參數

    public String errMsg;
    public String jsonParam;
    public String callback;
    protected HttpServletRequest request;
    protected HttpServletResponse response;

     * 每次請求都會帶上
     * @param jsonParam

     * @param openId
     */
    @ModelAttribute
    public void setReqAndRes(Map session, String openId, String errMsg,
            String jsonParam, String callback, HttpServletRequest request,
            HttpServletResponse response) {

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    /**
     * 采用json 或 jsonp

     */
    public static void printJson(String callback,HttpServletResponse response,String result){
        boolean jsonP = false;

        } else {

微信小程序代碼實現

小帥一點資訊小程序代碼是開源的哦

學習并使用了微信小程序scroll-view組件

相關代碼請移步gitee查看 https://gitee.com/xshuai/weix...

微信小程序上傳限制為2048kb。相關圖片過多超了限制。因此需要用到云存儲。使用阿里云 騰訊云都可以哦。在親測的情況下發現。即使云儲存域名不在小程序里面添加也是可以正常訪問哦

以上就是接入的整體流程 可以掃碼體驗哦
