效果圖
1.準備工作
申請微信訂閱號(個人只能申請訂閱號,而且沒什麽功能,也無法認證),申請完畢,點擊 開發=>基本配置,如下圖:
服務器配置需要有 域名 80端口,我猜你沒有,這裏推薦個實用工具,pagekite,下載鏈接,
這個工具需要 python2.7以上環境,還有郵箱一個,一個郵箱一個月,郵箱這東西大家懂得,
用pagekite申請完域名,就可以用自己的電腦做訂閱號服務器了.
2.服務器代碼
創建個springboot工程
pom.xml
<properties>
<project.build.sourceEncoding>UTF-8
<dependency>
<groupId>dom4j</groupId>
<artifactId>dom4j</artifactId>
<version>1.6.1</version>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
入口類
@SpringBootApplication public class WeChatApplication { public static void main(String[] args) { SpringApplication.run(WeChatApplication.class, args); System.out.println("====啟動成功===="); } }
application.properties,配置server.port=80
Controller,這個是處理微信請求,get方法就是微信公眾平臺 服務器配置url請求的路徑,post是處理用戶事件
@RestController public class WeChatController { @Autowired private WeChatService weChatService; /** * 處理微信服務器發來的get請求，進行簽名的驗證 * * signature 微信端發來的簽名 * timestamp 微信端發來的時間戳 * nonce 微信端發來的隨機字符串 * echostr 微信端發來的驗證字符串 */ @GetMapping(value = "wechat") public String validate(@RequestParam(value = "signature") String signature, @RequestParam(value = "timestamp") String timestamp, @RequestParam(value = "nonce") String nonce, @RequestParam(value = "echostr") String echostr) { return WeChatUtil.checkSignature(signature, timestamp, nonce) ? echostr : null; } /** * 此處是處理微信服務器的消息轉發的 */ @PostMapping(value = "wechat") public String processMsg(HttpServletRequest request) { // 調用核心服務類接收處理請求 return weChatService.processRequest(request); } }
Service,處理post請求
/** * 核心服務類 */ @Service public class WeChatServiceImpl implements WeChatService{ @Autowired private FeignUtil feignUtil; @Autowired private RedisUtils redisUtils; public String processRequest(HttpServletRequest request) { // xml格式的消息數據 String respXml = null; // 默認返回的文本消息內容 String respContent; try { // 調用parseXml方法解析請求消息 Map<String,String> requestMap = WeChatUtil.parseXml(request); // 消息類型 String msgType = (String) requestMap.get(WeChatContant.MsgType); String mes = null; // 文本消息 if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_TEXT)) { mes =requestMap.get(WeChatContant.Content).toString(); if(mes!=null&&mes.length()<2){ List<ArticleItem> items = new ArrayList<>(); ArticleItem item = new ArticleItem(); item.setTitle("照片墻"); item.setDescription("阿貍照片墻"); item.setPicUrl("http://changhaiwx.pagekite.me/photo-wall/a/iali11.jpg"); item.setUrl("http://changhaiwx.pagekite.me/page/photowall"); items.add(item); item = new ArticleItem(); item.setTitle("哈哈"); item.setDescription("一張照片"); item.setPicUrl("http://changhaiwx.pagekite.me/images/me.jpg"); item.setUrl("http://changhaiwx.pagekite.me/page/index"); items.add(item); item = new ArticleItem(); item.setTitle("小遊戲2048"); item.setDescription("小遊戲2048"); item.setPicUrl("http://changhaiwx.pagekite.me/images/2048.jpg"); item.setUrl("http://changhaiwx.pagekite.me/page/game2048"); items.add(item); item = new ArticleItem(); item.setTitle("百度"); item.setDescription("百度一下"); item.setPicUrl("https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1505100912368&di=69c2ba796aa2afd9a4608e213bf695fb&imgtype=0&src=http%3A%2F%2Ftx.haiqq.com%2Fuploads%2Fallimg%2F170510%2F0634355517-9.jpg"); item.setUrl("http://www.baidu.com"); items.add(item); respXml = WeChatUtil.sendArticleMsg(requestMap, items); }else if("我的信息".equals(mes)){ Map<String, String> userInfo = getUserInfo(requestMap.get(WeChatContant.FromUserName)); System.out.println(userInfo.toString()); String nickname = userInfo.get("nickname"); String city = userInfo.get("city"); String province = userInfo.get("province"); String country = userInfo.get("country"); String headimgurl = userInfo.get("headimgurl"); List<ArticleItem> items = new ArrayList<>(); ArticleItem item = new ArticleItem(); item.setTitle("你的信息"); item.setDescription("昵稱:"+nickname+" 地址:"+country+" "+province+" "+city); item.setPicUrl(headimgurl); item.setUrl("http://www.baidu.com"); items.add(item); respXml = WeChatUtil.sendArticleMsg(requestMap, items); } } // 圖片消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_IMAGE)) { respContent = "您發送的是圖片消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 語音消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_VOICE)) { respContent = "您發送的是語音消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 視頻消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_VIDEO)) { respContent = "您發送的是視頻消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 地理位置消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_LOCATION)) { respContent = "您發送的是地理位置消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 鏈接消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_LINK)) { respContent = "您發送的是鏈接消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 事件推送 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_EVENT)) { // 事件類型 String eventType = (String) requestMap.get(WeChatContant.Event); // 關註 if (eventType.equals(WeChatContant.EVENT_TYPE_SUBSCRIBE)) { respContent = "謝謝您的關註！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 取消關註 else if (eventType.equals(WeChatContant.EVENT_TYPE_UNSUBSCRIBE)) { // TODO 取消訂閱後用戶不會再收到公眾賬號發送的消息，因此不需要回復 } // 掃描帶參數二維碼 else if (eventType.equals(WeChatContant.EVENT_TYPE_SCAN)) { // TODO 處理掃描帶參數二維碼事件 } // 上報地理位置 else if (eventType.equals(WeChatContant.EVENT_TYPE_LOCATION)) { // TODO 處理上報地理位置事件 } // 自定義菜單 else if (eventType.equals(WeChatContant.EVENT_TYPE_CLICK)) { // TODO 處理菜單點擊事件 } } mes = mes == null ?
