效果图

1.准备工作

申请微信订阅号(个人只能申请订阅号,而且没什么功能,也无法认证),申请完毕,点击 开发=>基本配置,如下图:

服务器配置需要有 域名 80端口,我猜你没有,这里推荐个实用工具,pagekite,下载链接,

这个工具需要 python2.7以上环境,还有邮箱一个,一个邮箱一个月,邮箱这东西大家懂得,

用pagekite申请完域名,就可以用自己的电脑做订阅号服务器了.

2.服务器代码

创建个springboot工程

pom.xml

<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!-- 使thymeleaf支持h5标签 --> <dependency> <groupId>net.sourceforge.nekohtml</groupId> <artifactId>nekohtml</artifactId> <version>1.9.22</version> </dependency>　　　　<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>

入口类

@SpringBootApplicationpublic class WeChatApplication { public static void main(String[] args) { SpringApplication.run(WeChatApplication.class, args); System.out.println("====启动成功===="); }}

application.properties,配置server.port=80

Controller,这个是处理微信请求,get方法就是微信公众平台 服务器配置url请求的路径,post是处理用户事件

@RestControllerpublic class WeChatController { @Autowired private WeChatService weChatService; /** * 处理微信服务器发来的get请求，进行签名的验证 * * signature 微信端发来的签名 * timestamp 微信端发来的时间戳 * nonce 微信端发来的随机字符串 * echostr 微信端发来的验证字符串 */ @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; } /** * 此处是处理微信服务器的消息转发的 */ @PostMapping(value = "wechat") public String processMsg(HttpServletRequest request) { // 调用核心服务类接收处理请求 return weChatService.processRequest(request); }}

Service,处理post请求

/** * 核心服务类 */@Servicepublic class WeChatServiceImpl implements WeChatService{ @Autowired private FeignUtil feignUtil; @Autowired private RedisUtils redisUtils; public String processRequest(HttpServletRequest request) { // xml格式的消息数据 String respXml = null; // 默认返回的文本消息内容 String respContent; try { // 调用parseXml方法解析请求消息 Map<String,String> requestMap = WeChatUtil.parseXml(request); // 消息类型 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("照片墙"); item.setDescription("阿狸照片墙"); 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("一张照片"); 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("小游戏2048"); item.setDescription("小游戏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("昵称:"+nickname+" 地址:"+country+" "+province+" "+city); item.setPicUrl(headimgurl); item.setUrl("http://www.baidu.com"); items.add(item); respXml = WeChatUtil.sendArticleMsg(requestMap, items); } } // 图片消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_IMAGE)) { respContent = "您发送的是图片消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 语音消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_VOICE)) { respContent = "您发送的是语音消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 视频消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_VIDEO)) { respContent = "您发送的是视频消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 地理位置消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_LOCATION)) { respContent = "您发送的是地理位置消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 链接消息 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_LINK)) { respContent = "您发送的是链接消息！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 事件推送 else if (msgType.equals(WeChatContant.REQ_MESSAGE_TYPE_EVENT)) { // 事件类型 String eventType = (String) requestMap.get(WeChatContant.Event); // 关注 if (eventType.equals(WeChatContant.EVENT_TYPE_SUBSCRIBE)) { respContent = "谢谢您的关注！"; respXml = WeChatUtil.sendTextMsg(requestMap, respContent); } // 取消关注 else if (eventType.equals(WeChatContant.EVENT_TYPE_UNSUBSCRIBE)) { // TODO 取消订阅后用户不会再收到公众账号发送的消息，因此不需要回复 } // 扫描带参数二维码 else if (eventType.equals(WeChatContant.EVENT_TYPE_SCAN)) { // TODO 处理扫描带参数二维码事件 } // 上报地理位置 else if (eventType.equals(WeChatContant.EVENT_TYPE_LOCATION)) { // TODO 处理上报地理位置事件 } // 自定义菜单 else if (eventType.equals(WeChatContant.EVENT_TYPE_CLICK)) { // TODO 处理菜单点击事件 } } mes = mes == null ? "不知道你在干嘛" : mes; if(respXml == null) respXml = WeChatUtil.sendTextMsg(requestMap, mes); System.out.println(respXml); return respXml; } catch (Exception e) { e.printStackTrace(); } return ""; }}

微信常量

public class WeChatContant { //APPID public static final String appID = "appid"; //appsecret public static final String appsecret = "appsecret"; // Token public static final String TOKEN = "zch"; public static final String RESP_MESSAGE_TYPE_TEXT = "text"; public static final Object REQ_MESSAGE_TYPE_TEXT = "text"; public static final Object REQ_MESSAGE_TYPE_IMAGE = "image"; public static final Object REQ_MESSAGE_TYPE_VOICE = "voice"; public static final Object REQ_MESSAGE_TYPE_VIDEO = "video"; public static final Object REQ_MESSAGE_TYPE_LOCATION = "location"; public static final Object REQ_MESSAGE_TYPE_LINK = "link"; public static final Object REQ_MESSAGE_TYPE_EVENT = "event"; public static final Object EVENT_TYPE_SUBSCRIBE = "SUBSCRIBE"; public static final Object EVENT_TYPE_UNSUBSCRIBE = "UNSUBSCRIBE"; public static final Object EVENT_TYPE_SCAN = "SCAN"; public static final Object EVENT_TYPE_LOCATION = "LOCATION"; public static final Object EVENT_TYPE_CLICK = "CLICK"; public static final String FromUserName = "FromUserName"; public static final String ToUserName = "ToUserName"; public static final String MsgType = "MsgType"; public static final String Content = "Content"; public static final String Event = "Event"; }

图文消息实体bean

public class ArticleItem { private String Title; private String Description; private String PicUrl; private String Url; public String getTitle() { return Title; } public void setTitle(String title) { Title = title; } public String getDescription() { return Description; } public void setDescription(String description) { Description = description; } public String getPicUrl() { return PicUrl; } public void setPicUrl(String picUrl) { PicUrl = picUrl; } public String getUrl() { return Url; } public void setUrl(String url) { Url = url; } }

好了运行项目,在公众平台配置好url,个人订阅号完成.
