java http api 请求

java 代码：

package com.zkhc.server.modular.system.utils;

import cn.stylefeng.roses.core.reqres.response.SuccessResponseData;
import com.alibaba.fastjson.JSONObject;
import jdk.nashorn.internal.runtime.logging.Logger;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

import java.io.IOException;

public class http_utils {
    /**
    * http post 请求
    * */

    public SuccessResponseData post(String url, JSONObject jsonObj) {
        try {
            HttpClient httpclient = HttpClients.createDefault();
            HttpPost httppost = new HttpPost(url);
            httppost.addHeader("Content-Type", "application/json; charset=utf-8");

            StringEntity se = new StringEntity(jsonObj.toString(), "utf-8");
            httppost.setEntity(se);

            HttpResponse response = httpclient.execute(httppost);
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                HttpEntity result = response.getEntity();
                return new SuccessResponseData(response.getStatusLine().getStatusCode(), response.getStatusLine().getReasonPhrase(), result);
            }else{
                return new SuccessResponseData(500, response.getStatusLine().getReasonPhrase(), response.getEntity());
            }
        } catch (IOException e) {
            return new SuccessResponseData(500, e.getMessage(), null);
        }
    }
}

 请求相应封装代码：

package cn.stylefeng.roses.core.reqres.response;

/**
 * 请求成功的返回
 *
 * @author stylefeng
 * @Date 2018/1/4 22:38
 */
public class SuccessResponseData extends ResponseData {

    public SuccessResponseData() {
        super(true, DEFAULT_SUCCESS_CODE, DEFAULT_SUCCESS_MESSAGE, null);
    }

    public SuccessResponseData(Object object) {
        super(true, DEFAULT_SUCCESS_CODE, DEFAULT_SUCCESS_MESSAGE, object);
    }

    public SuccessResponseData(Integer code, String message, Object object) {
        super(true, code, message, object);
    }
}

package cn.stylefeng.roses.core.reqres.response;


import lombok.Data;

/**
 * 返回给前台的通用包装
 *
 * @author stylefeng
 * @Date 2018/1/4 22:37
 */
@Data
public class ResponseData {

    public static final String DEFAULT_SUCCESS_MESSAGE = "请求成功";

    public static final String DEFAULT_ERROR_MESSAGE = "网络异常";

    public static final Integer DEFAULT_SUCCESS_CODE = 200;

    public static final Integer DEFAULT_ERROR_CODE = 500;

    /**
     * 请求是否成功
     */
    private Boolean success;

    /**
     * 响应状态码
     */
    private Integer code;

    /**
     * 响应信息
     */
    private String message;

    /**
     * 响应对象
     */
    private Object data;

    public ResponseData() {
    }

    public ResponseData(Boolean success, Integer code, String message, Object data) {
        this.success = success;
        this.code = code;
        this.message = message;
        this.data = data;
    }

    public static SuccessResponseData success() {
        return new SuccessResponseData();
    }

    public static SuccessResponseData success(Object object) {
        return new SuccessResponseData(object);
    }

    public static SuccessResponseData success(Integer code, String message, Object object) {
        return new SuccessResponseData(code, message, object);
    }

    public static ErrorResponseData error(String message) {
        return new ErrorResponseData(message);
    }

    public static ErrorResponseData error(Integer code, String message) {
        return new ErrorResponseData(code, message);
    }

    public static ErrorResponseData error(Integer code, String message, Object object) {
        return new ErrorResponseData(code, message, object);
    }
}

调用代码：

 Map<String, Object> ngrok_map = new HashMap<>();
        ngrok_map.put("type", serverInfo.getPortType());
        ngrok_map.put("port", serverInfo.getPort());

        JSONObject post_data = new JSONObject(ngrok_map);
        SuccessResponseData srd = new http_utils().post(url, post_data);
