概述
货架商品识别与管理（Retail Image Recognition）是基于深度学习、图像检测、图像识别等技术，为新零售品牌商/经销商提供AI商品识别能力的阿里云产品；适用于货架商品识别、陈列识别、形象化识别等多个业务应用场景中，提供对渠道的数据全面精准洞察，助力渠道业务管理实现数字化、智能化的转型升级。目前该产品还在公测预览版免费试用阶段，下面通过结合Python SDK介绍该产品的使用流程。
操作步骤
1、服务开通
申请一般需要一到三个工作日审批通过，如果想加快审批流程，可以提工单，注意提工单的时候带上申请的账户Uid。
2、创建项目
3、控制台快速测试
4、Python SDK测试
4.1 Python SDK的安装可以参考链接
4.2 Code Sample
```js
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.request import CommonRequest
import json
import time
DefaultProfile.getProfile的参数分别是access_key_id, access_key_secret，region(目前固定为杭州) https://yq.aliyun.com/articles/693979
client = AcsClient("LTAIOZZg**", "v7CjUJCMk7j9aKduMAQLjy**", "cn-hangzhou")
createTask API 创建商品识别任务
def createTask(Appkey:"实例ID",ImageLeftTop:"影像左上"):
request = CommonRequest()
request.set_method("POST")
request.set_domain("retailir.cn-hangzhou.aliyuncs.com")
request.set_action_name("CreateTask")
request.set_version("2019-09-06")
request.set_accept_format('json')
request.add_body_params("Appkey", Appkey)
request.add_body_params("TaskName", "test1")
request.add_body_params("ImageLeftTop", ImageLeftTop)
response = client.get_response(request)
response_str = str(response[2], 'utf-8') # bytes 转 string
print(response_str) # 打印输出结果
JobId = (json.loads(response_str))["Task"]["JobId"] # 获取任务id
return JobId
getTask API 获取提交任务的结果
def getTask(Appkey:"实例ID", JobId:"任务Id"):
request = CommonRequest()
request.set_method("POST")
request.set_domain("retailir.cn-hangzhou.aliyuncs.com")
request.set_action_name("GetTask")
request.set_version("2019-09-06")
request.set_accept_format('json')
request.add_body_params("Appkey", Appkey)
request.add_body_params("JobId", JobId)
response = client.get_response(request)
response_str = str(response[2], 'utf-8') # bytes 转 string
print(response_str) # 打印输出结果
if name == 'main':
Appkey = "GGU4dslp**"
ImageLeftTop = "https://img.alicdn.com/tfs/TB1OFfegEY1gK0jSZFCXXcwqXXa-720-1440.png"
JobId = createTask(Appkey, ImageLeftTop)
time.sleep(10) # 创建完的Task需要后端等待一段时间才能获取运行结果
getTask(Appkey, JobId)

5、其它开发语言的调用问题
目前提供的两个API接口都是通过pop接口对接，所以使用阿里云的core sdk均可做认证对接，然后使用CommonRequest()方法即可完成调用过程。相关语言可以参考阿里云新版人脸识别综述 新版本SDK调用示例参考部分即可。
