本文整理了Java中org.eclipse.californium.core.coap.Request类的一些代码示例，展示了Request类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Request类的具体详情如下：
包路径：org.eclipse.californium.core.coap.Request
类名称：Request

Request介绍

[英]Request represents a CoAP request and has either the Type CON or NON and one of the CoAP.Codes GET, POST, PUT or DELETE. A request must be sent over an Endpoint to its destination. By default, a request uses the default endpoint defined by EndpointManager. The server responds with a Response.

A client can send a request and wait for for a response using a synchronous (blocking) call like this:

Request request = new Request(Code.GET); 
request.setURI("coap://example.com:5683/sensors/temperature"); 
request.send(); 
Response response = request.waitForResponse();

A client may also send requests asynchronously (non-blocking) and define a handler to be invoked when a response arrives. This is in particular useful when a client wants to observe the target resource and react to notifications. For instance:

Request request = new Request(Code.GET); 
request.setURI("coap://example.com:5683/sensors/temperature"); 
request.setObserve(); 
request.addMessageObserver(new MessageObserverAdapter() {

[中]请求表示CoAP请求，类型为CON或NON，其中一个为CoAP。代码获取、发布、放置或删除。请求必须通过端点发送到目的地。默认情况下，请求使用EndpointManager定义的默认端点。服务器会做出响应。
客户端可以使用如下同步（阻塞）调用发送请求并等待响应：

Request request = new Request(Code.GET); 
request.setURI("coap://example.com:5683/sensors/temperature"); 
request.send(); 
Response response = request.waitForResponse();

客户端还可以异步（非阻塞）发送请求，并定义响应到达时要调用的处理程序。当客户端希望观察目标资源并对通知做出反应时，这一点尤其有用。例如：

Request request = new Request(Code.GET); 
request.setURI("coap://example.com:5683/sensors/temperature"); 
request.setObserve(); 
request.addMessageObserver(new MessageObserverAdapter() {

代码示例

/**
 * Send request with option "cancel observe" (GET with Observe=1).
 */
private void sendCancelObserve() {
  Request request = this.request;
  Request cancel = Request.newGet();
  cancel.setDestination(request.getDestination());
  cancel.setDestinationPort(request.getDestinationPort());
  // use same Token
  cancel.setToken(request.getToken());
  // copy options, but set Observe to cancel
  cancel.setOptions(request.getOptions());
  cancel.setObserveCancel();
  // dispatch final response to the same message observers
  for (MessageObserver mo : request.getMessageObservers()) {
    cancel.addMessageObserver(mo);
  }
  endpoint.sendRequest(cancel);
}
