java - Httpclient-4.5.2.jar setEntity显示“找不到符号”(JAVA-NetBeans 8)

我正在尝试使用从网站获得的一些代码，该网站具有通过API（http://developer.fantasydata.com）公开提供的体育数据。

该站点提供了一些示例JAVA代码来发出http请求。由于某种原因，已声明的请求（请求）的setEntity方法显示“找不到符号错误。

    package epl.fixtures.test.app;

import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class EPLFixturesTestApp {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here

        HttpClient httpclient = HttpClients.createDefault();

        try
        {
            URIBuilder builder = new URIBuilder("https://api.fantasydata.net/soccer/v2/json/CompetitionDetails/EPL");


            URI uri = builder.build();
            HttpGet request = new HttpGet(uri);
            request.setHeader("Ocp-Apim-Subscription-Key", "****************");


            // Request body
            StringEntity reqEntity = new StringEntity("{body}");
            request.setEntity(reqEntity);

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            if (entity != null)
            {
                System.out.println(EntityUtils.toString(entity));
            }
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }

    }

}

引起问题的行是request.setEntity（reqEntity）;。线

谁能向我解释一下？我已将apache中所有相关的jar文件添加到项目库目录中。

谢谢

最佳答案

HttpGet没有setEntity方法。
这是有道理的，因为请求主体在GET请求中没有意义。

仅实现HttpEntityEnclosingRequest的类具有此方法。

我不知道为什么文档会使用它，但是当省略这两行（无论如何看起来毫无意义）时，它似乎可以工作。码：

URIBuilder builder = new URIBuilder("https://api.fantasydata.net/soccer/v2/json/CompetitionDetails/EPL");
URI uri = builder.build();
HttpGet request = new HttpGet(uri);
request.setHeader("Ocp-Apim-Subscription-Key", "****************");
HttpResponse response = httpclient.execute(request);
HttpEntity entity = response.getEntity();

if (entity != null)
{
    System.out.println(EntityUtils.toString(entity));
}
