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
UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-parent 1.5.9.RELEASE org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-thymeleaf net.sourceforge.nekohtml nekohtml 1.9.22 dom4j dom4j 1.6.1 org.springframework.boot spring-boot-maven-plugin
入口类
@SpringBootApplication
public 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
@RestController
public 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
