HttpClient学习—— AsyncHttpClient使用

Posted 2021-12-02 fonxian

一、介绍

This class support asynchronous and synchronous HTTP requests.

AsyncHttpClient 支持同步、异步Http请求。

二、简单使用

引入依赖

<dependencies>

        <dependency>
            <groupId>org.asynchttpclient</groupId>
            <artifactId>async-http-client</artifactId>
            <version>2.8.1</version>
        </dependency>

        <dependency>
            <groupId>net.tascalate</groupId>
            <artifactId>net.tascalate.concurrent</artifactId>
            <version>0.8.0</version>
        </dependency>

    </dependencies>


    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

执行同步请求

/**
     * 执行同步HTTP请求
     */
    public void synRequest() {

        String url = "http://www.baidu.com";
        AsyncHttpClient c = new DefaultAsyncHttpClient();
        Future<Response> f = c.prepareGet(url).execute();
        try {
            System.out.println(f.get());
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }

    }
