本文介绍如何使用Flink实现HTTP Sink，将实时计算结果发送到HTTP服务。通过具体代码示例展示了如何配置HTTP客户端、构建请求并获取响应。

前几天,发愁怎么样把flink实时计算的结果展示到UI上,所以就有了我接下来研究的 flink httpsink

依赖:

   <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.5</version>
        </dependency>

代码:

public class HttpSink implements SinkFunction<SdkLampStatusDto> {



    @Override
    public void invoke(SdkLampStatusDto data, Context context) throws Exception {
        CloseableHttpClient client = HttpClients.createDefault();
        URIBuilder uriBuilder = new URIBuilder("http://localhost:8080/doGetControllerTwo?crossId="+data.getCrossId() + "&phaseNo="+data.getPhaseNo() +"&lampStatus="+data.getLampStatus() + "&lastSecond="+data.getLastSecond());

        HttpPost httpPost = new HttpPost();
        HttpGet httpGet = new HttpGet(uriBuilder.build());
        httpGet.addHeader
