AsyncHttpClient版本再1.9前后有有较大的差异，因为内部采用Netty进行网络请求，因此异步的性能比HttpClient更加的优秀 Netty：是一个异步事件驱动的网络应用框架，用于快速开发可维护的高性能服务器和客户端，它是对JDK的NIO（非阻塞IO）进行了封装，让使用变的简单，安全。 关于Netty详细的简单介绍请参考：https://www.jianshu.com/p/a4e03835921a 使用async-http-client.jar进行get和post请求的简单实例:
依赖jir包 依赖jar包说明：1.9前后的api还是存在一些差异的，比如set参数的api的变化等。
<dependency> <groupId>com.ning</groupId> <artifactId>async-http-client</artifactId> <version>1.8.17</version> </dependency>
gradle
compile group: 'com.ning', name: 'async-http-client', version: '1.8.17'
Kotlin（可以与java相互转化）示例代码
import com.ning.http.client.* import java.util.concurrent.Future import java.util.concurrent.TimeUnit object HttpClientUtil { @Throws fun httpPost(asyncHttpClient: AsyncHttpClient, url: String, params: Map<String, String?>): Response? { val builder = asyncHttpClient.preparePost(url) .setBodyEncoding("UTF-8") params?.entries?.forEach { (t, u) -> builder.addParameter(t, u) } return builder.execute()?.get(10, TimeUnit.SECONDS) } @Throws fun httpGet(asyncHttpClient: AsyncHttpClient, url: String, params: Map<String, String>?): Future<Response>? { val builder = asyncHttpClient.prepareGet(url) .setBodyEncoding("UTF-8") params?.entries?.forEach { (t, u) -> builder.addParameter(t, u) } return builder.execute() } @Throws fun httpPostJson(url: String, header: Map<String, String>, body: String): Response? { val asyncHttpClient = AsyncHttpClient() val builder = asyncHttpClient.preparePost(url) .setBodyEncoding("UTF-8") .setBody(body) header.forEach { (t, u) -> builder.addHeader(t, u) } val response = builder.execute()?.get(10, TimeUnit.SECONDS) asyncHttpClient.close() return response } }
调用：
fun useHttp(): Boolean{ val response = HttpClientUtil .httpPostJson(ReadConfItako.getInstance().getProperty("blacklist.api.url"), mapOf(), body.toString()) return response?.statusText.equals("ok") }
