Java实现天猫精灵与智能设备的对接

天猫精灵与公司智能设备的对接。刚接到这个任务的时候对于一个刚毕业一个月的应届生我来说，有点像巨石，不过经历了10多天的自己琢磨，还是终于把这个新东西搞出来了。楼主是学的java，但在查询相关文章的时候发现没有一篇是用java实现的。所以在这里写一篇关于实现的文章阐述一下这个对接里面所需要的一些细节以及，实现流程。首先我们需要了解的是Aligenie开发者平台。

https://open.bot.tmall.com/

这里有必要贴一张整个接入的流程图

这个平台的登录可以用淘宝账号登录。登录后

我们需要先进行技能的创建，点击添加新技能

技能信息这一栏信息我就不做过多的阐述自己随便填一下就是了。作为测试取名Test或者什么其他的都OK。填写完成后点击下一步：

这个页面对开发者来说真的可谓是重中之重。

第一栏账户授权链接应填写我们开发者为Aligenie平台提供的授权登录页面（自己编写）

第二栏，第三栏Client ID和Client Secret这里设置的作用就是平台识别你新建技能用的可以自己随便填写。

Aceess Token URL这个地址需要解释一下官方文档中标识如下：

这个地址其实就是当你完成授权登录这一步后会返回一个code值，然后将code值添加进OAuth2.0请求中将整个请求转发给

你填写AccessTokenURL方法接口中去。通过传递的code换取访问令牌

https://XXXXX/token?grant_type=authorization_code&client_id=XXXXX&client_secret=XXXXXX&code=XXXXXXXX&redirect_uri=https%3A%2F%2Fopen.bot.tmall.com%2Foauth%2Fcallback

最后一个必填项开发者网关地址是当平台接受到你的返回的AccessToken后要将平台的智能家居协议发送到的一个接口。该接口用来接收协议然后按照官方文档给出的返回json体的格式返回你要接入的智能设备的一些参数。

上述的设备发现请求就是平台向网关地址中Post协议。而下面的就是你需要返回的东西。注册技能的地址填写就这么几个要点。

这边填写完后先不用上线什么的先做一个本地的测试再说。填完后我们返回技能主页会出现该技能的图标点进去。这时我们需要测试自己的技能，点击账户配置会跳转到你所写的登录页面。登录页的账号密码填写公司中存储的用户的账号密码就可。

当跳转到这个界面时我们看网址信息

http://www.XXXXX.com/test2/merchantHTML/merchantlogin.jsp?redirect_uri=https%3A%2F%2Fopen.bot.tmall.com%2Foauth%2Fcallback%3FskillId%3D18105%26token%3DMjM0MDgzODYwMEFGRUhJTkZEVlE%3D&client_id=hbsycjn2010&response_type=code&state=0.5252341172795741

从redirect后的信息都是平台为我们自己加上的。登录成功后我们需要将请求转发给我们生成Code并生成与Code对应的AcessToken的这个接口中为平台反馈AcessToken。

我这里用的是SSM框架实现的

userService.java

package com.obj.service;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.obj.dao.userDao;
import com.obj.entity.user;@Service
public class userService {@Resourceprivate userDao userdao;public user UserLogin(String username,String password){return userdao.UserLogin(username, password);}public user IdentifyUsername(String username){return userdao.IdentifyUsername(username);}public user IdentifyPassword(String username,String password){return userdao.IdentifyPassword(username, password);}
}

userDao.java

package com.obj.dao;
import com.obj.entity.*;
public interface userDao {public user UserLogin(String username,String password);public user IdentifyUsername(String username);public user IdentifyPassword(String username,String password);}

userMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper

点击登录并授权，如果在生成CODE，通过生成的CODE换取AccessToken返回给平台这几步上都没有差错则会跳转到一下界面。
