AsyncHttpClient的介绍和使用_org.asynchttpclient

GitHub 地址：https://github.com/AsyncHttpClient/async-http-client

AsyncHttpClient目前版本2.1，内部采用Netty进行网络请求，因此比HttpClient更加优秀

maven

<dependency>
            <groupId>org.asynchttpclient</groupId>
            <artifactId>async-http-client</artifactId>
            <version>2.1.0-alpha21</version>
        </dependency>

实例：

AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient();
Future<Response> f = asyncHttpClient.prepareGet("http://www.example.com/").execute();
Response r = f.get();

测试使用

public class AsyncHttpUtil {
 
    public static Future<Response> get(String url, AsyncCompletionHandler<Response> completionHandler){
        AsyncHttpClient asyncHttpClient = new DefaultAsyncHttpClient(new DefaultAsyncHttpClientConfig.Builder()
                .setConnectTimeout(10000)
                .setRequestTimeout(10000)
                .build());
        RequestBuilder builder=new RequestBuilder();
        builder.setUrl(url);
        builder.addQueryParam("name","test");
 
        return  asyncHttpClient.executeRequest(builder.build(),completionHandler);
    }
 
    public static void main(String[] args) {
       Future<Response> future=  AsyncHttpUtil.get("http://www.baidu.com", new AsyncCompletionHandler<Response>() {
            @Override
            public Response onCompleted(Response response) throws Exception {
                if(response.hasResponseStatus()){
                    System.out.println("1111");
                    System.out.println(response.getResponseBody());
                }
                return response;
            }
 
            @Override
            public void onThrowable(Throwable t) {
                super.onThrowable(t);
            }
        });
        try {
            Response response= future.get();
 
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }
    }
}
