springboot请求接口工具类

ApiHttpUtils

url是请求的地址，params是请求的参数
然后拿到result再对数据进行处理

import com.alibaba.fastjson.JSON;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;
import java.util.Map;

public class ApiHttpUtils {
    public static String getHttpData(String url, Map params) {
        String result="";
        try{
            CloseableHttpClient client = HttpClients.createDefault();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setEntity(new StringEntity(JSON.toJSONString(params)));
//        httpPost.setHeader("Accept", "application/json");
            httpPost.setHeader("Content-type", "application/json");
            CloseableHttpResponse response = client.execute(httpPost);
            if(response!=null){
                result = EntityUtils.toString(response.getEntity(), "UTF-8");
            }
            client.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }
}
