Question

我正在尝试将HTTPAsyncCLient用于火灾并忘记在我的应用中。

http://hc.apache.org/httpcomponents-asyncclient-4.0.x/

我在这里给出了这个例子： http://hc.apache.org/httpcomponents-asyncclient-4.0.x/httpasyncclient/examples/org/apache/http/examples/nio/client/AsyncClientHttpExchange.java

我的代码如下：

           CloseableHttpAsyncClient httpclient = HttpAsyncClients.createDefault();
           httpclient.start();
           HttpGet request = new HttpGet(url);
           Future<HttpResponse> future = httpclient.execute(request, null);
          /*try {
            HttpResponse resp = future.get();
            StringBuilder sb = new StringBuilder();
            BufferedReader reader = new BufferedReader(new InputStreamReader(resp.getEntity().getContent()));
            String line = null;

            while ((line = reader.readLine()) != null) {
                sb.append(line);
            }
            String fr = sb.toString();
          } catch (InterruptedException e) {
          // TODO Auto-generated catch block
          e.printStackTrace();
          } catch (ExecutionException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
          }*/
       httpclient.close();

如果我取消注释评论部分，一切正常。但我想要做的是一个火灾和忘记请求。因此，当我按上述方式注释掉该部分时，不会发出HTTP请求。知道我做错了什么吗？我该怎么办才能解决火灾和忘记请求？

在请求完成之前，您的httpclient实例无法关闭。

虽然我不确定，但我会建议

// ONCE
CloseableHttpAsyncClient httpclient = HttpAsyncClients.createDefault();
httpclient.start();


// for every fire and forget request
HttpGet request = new HttpGet(url);
httpclient.execute(request, null);`

让您的客户端在请求之间保持活动状态，因此不要调用close（重新使用实例）

使用HttpAsyncClients在java中触发和忘记
