"/chat" 是我最终项目的请求Controller URL路径
下面是homecontroller
[java] view plain copy
@Controller
@RequestMapping("/*")
public class HomeController {
private String Token = "123456789abcdef";
@RequestMapping(value = "chat", method = { RequestMethod.GET, RequestMethod.POST })
@ResponseBody
public void liaotian(Model model, HttpServletRequest request, HttpServletResponse response) {
System.out.println("进入chat");
boolean isGet = request.getMethod().toLowerCase().equals("get");
if (isGet) {
String signature = request.getParameter("signature");
String timestamp = request.getParameter("timestamp");
String nonce = request.getParameter("nonce");
String echostr = request.getParameter("echostr");
System.out.println(signature);
System.out.println(timestamp);
System.out.println(nonce);
System.out.println(echostr);
access(request, response);
} else {
// 进入POST聊天处理
System.out.println("enter post");
try {
// 接收消息并返回消息
acceptMessage(request, response);
} catch (IOException e) {
e.printStackTrace();
}
}
}
