业务需要调个三方接口

使用GET请求方式

但是！请求参数不在Query中，竟然在Body中，使用Json格式传参

在API调试工具里面可以调通

在java代码里，死活调不通

网上搜了搜，找到一个靠谱的，记录一下

import org.apache.http.client.methods.HttpEntityEnclosingRequestBase;
import java.net.URI;

public class HttpGetWithEntity extends HttpEntityEnclosingRequestBase {
    private final static String METHOD_NAME = "GET";

    @Override
    public String getMethod() {
        return METHOD_NAME;
    }
    public HttpGetWithEntity() {
        super();
    }
    public HttpGetWithEntity(final URI uri) {
        super();
        setURI(uri);
    }
    public HttpGetWithEntity(final String uri) {
        super();
        setURI(URI.create(uri));
    }
}

        params.put("userId","222");
        params.put("timeout","333");
        params.put("fileUrl","444");

        HttpGetWithEntity httpGetWithEntity = new HttpGetWithEntity("http://*........");
        httpGetWithEntity.setEntity(new StringEntity(JSONObject.toJSONString(params), ContentType.APPLICATION_JSON));
        httpGetWithEntity.setHeader("access-token","555");
        httpGetWithEntity.setHeader("Content-Type","application/json");

        CloseableHttpResponse response9 = HttpClients.createDefault().execute(httpGetWithEntity);
        HttpEntity entity = response9.getEntity();

        String result = "";
        if (entity != null) {
            result = EntityUtils.toString(entity, "UTF-8");
        }
        response9.close();
        System.out.println(result);
    }
