概述
本文主要演示基于阿里云现有通用Http Go SDK调用阿里云新版人脸识别服务，分别DetectFace方法使用图片URL、VerifyFace方法使用本地为示例演示。
环境准备
1、Go语言版本
go version go1.12.7 windows/amd64
2、IDE
LiteIDE
3、SDK安装
go get -u github.com/aliyun/alibaba-cloud-sdk-go/sdk
测试代码
1、DetectFace Sample
// demo1 project main.go
package main
import (
"fmt"
"github.com/aliyun/alibaba-cloud-sdk-go/sdk"
"github.com/aliyun/alibaba-cloud-sdk-go/sdk/requests"
)
func main() {
client, err := sdk.NewClientWithAccessKey("cn-shanghai", "********", "********") // ak,sk信息
if err != nil {
// Handle exceptions
panic(err)
}
request := requests.NewCommonRequest()
request.Method = "POST"
request.Product = "FaceAPI"
request.Domain = "face.cn-shanghai.aliyuncs.com"
request.Version = "2018-12-03"
request.Scheme = "https"
request.ApiName = "DetectFace"
request.QueryParams["ImageUrl"] = "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1559655604341&di=3d6995f6dee1c4795d1827e754a00452&imgtype=0&src=http%3A%2F%2Fimg0.ph.126.net%2F90u9atgu46nnziAm1NMAGw%3D%3D%2F6631853916514183512.jpg" // Specify the requested regionId, if not specified, use the client regionId, then default regionId
request.AcceptFormat = "json"
request.TransToAcsRequest()
client.ProcessCommonRequest(request)
response, err := client.ProcessCommonRequest(request)
if err != nil {
fmt.Print(err.Error())
}
fmt.Printf(response.GetHttpContentString())
}
