004：快速整合微信公众号开发
1 微信公众号开发项目演示
今日课程任务
- 微信公众号架构设计原理
- 微信公众号如何本地开发测试
- 快速构建微信公众号服务项目
- 构建微信关键字回复内容
- 实现微信公众号实时查询城市温度
2 微信公众号开发设计原理
微信公众号开发的原理
当我们在微信客户端中，关注某个微信公众号之后，发出任何行为操作都会上传到微信公众号服务器端，再转发给开发者服务器。
3 基于natapp将本地项目发布到外网
外网映射工具的使用
目前有很多外网映射工具，比如NatApp、花生壳、ngrok等。
NatApp的使用
https://natapp.cn/ 购买域名、隧道，下载客户端
进入客户端下载解压目录，输入：natapp -authtoken=752cca064ce33a9b

4 对接微信公众号测试平台

数据库表结构

`keyword_name` varchar(255) DEFAULT NULL,
`keyword_value` varchar(255) DEFAULT NULL,
`create_time` datetime DEFAULT NULL,

) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
-- ----------------------------
-- Records of wechat_keywords
-- ----------------------------
INSERT INTO `wechat_keywords` VALUES ('1', '蚂蚁课堂', '蚂蚁课堂专注于java微服务开发网站www.mayikt.com', '2020-03-10 17:32:15', '2020-03-11 17:32:18', '1');
INSERT INTO `wechat_keywords` VALUES ('2', '余胜军', '蚂蚁课堂创始人', '2020-03-10 17:32:45', '2020-03-10 17:32:49', '2');

核心代码
@Data
public class WechatKeyword {
private Long id;
private String keywordName;
private String keywordValue;
private Date createTime;
private Date updateTime;
private Long version;
}
@Mapper
public interface KeywordMapper {
@Select("SELECT id as id ,keyword_name as keywordname,\n" +
"keyword_value as keywordvalue,create_time as createtime,\n" +
"update_time as updatetime ,version as version\n" +
" FROM wechat_keywords where keyword_name=#{keyword};")
WechatKeyword findByKeyword(String keyword);
}
@Component
@RefreshScope
public class MsgHandler extends AbstractHandler {
@Value("${mayikt.wx.defaultMsg}")
private String defaultMsg;
@Value("${mayikt.wx.rpcWeatherUrl}")
private String rpcWeatherUrl;
@Resource
private KeywordMapper keywordMapper;
@Override
public WxMpXmlOutMessage handle(WxMpXmlMessage wxMessage,
Map<String, Object> context, WxMpService weixinService,
WxSessionManager sessionManager) {
if (!wxMessage.getMsgType().equals(XmlMsgType.EVENT)) {
//TODO 可以选择将消息保存到本地
}
String content = wxMessage.getContent();
//1.先匹配数据库
WechatKeyword wechatKeyword = keywordMapper.findByKeyword(content);
if (wechatKeyword != null) {
String keywordValue = wechatKeyword.getKeywordValue();
return new TextBuilder().build(StringUtils.isEmpty(keywordValue) ? defaultMsg
: keywordValue, wxMessage, weixinService);
}
//2.调用第三方天气预报接口查询
String replaceRpcWeatherUrl = rpcWeatherUrl.replace("####", content);
JSONObject resultJsonObject = HttpClientUtils.httpGet(replaceRpcWeatherUrl);
if (resultJsonObject != null) {
JSONArray results = resultJsonObject.getJSONArray("results");
JSONObject resultsZeroJSONObject = results.getJSONObject(0);
JSONObject locationJSONObject = resultsZeroJSONObject.getJSONObject("location");
// 地址
String path = locationJSONObject.getString("path");
JSONObject nowJSONObject = resultsZeroJSONObject.getJSONObject("now");
String text = nowJSONObject.getString("text");
String temperature = nowJSONObject.getString("temperature");
String lastUpdate = resultsZeroJSONObject.getString("last_update");
String resultMsg = "您当前查询的城市" + content + ",天气为" + text + "天、实时温度为:" + temperature + "℃，" +
"最后更新的时间为:" + lastUpdate;
return new TextBuilder().build(resultMsg, wxMessage, weixinService);
}
//3.回复默认消息
return new TextBuilder().build(defaultMsg, wxMessage, weixinService);
}
}
新增配置文件
