Http请求工具类

用于Http请求使用

使用场景：参数为body,并需要设置Header头部信息

import com.alibaba.fastjson.JSONObject;

import java.io.*;
import java.net.ConnectException;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Map;

    //请求方法
    public static JSONObject httpsRequest(String requestUrl, String requestMethod, JSONObject paramJson) {
        BufferedReader bufferedReader = null;
        InputStreamReader inputStreamReader = null;
        InputStream inputStream = null;
        HttpURLConnection conn = null;
        try {
            URL url = new URL(requestUrl);
            conn = (HttpURLConnection) url.openConnection();
            Map<String, String> header = SignUtil.getHeader();
            //设置Header
            for (Map.Entry<String, String> map :header.entrySet()){
                conn.setRequestProperty(map.getKey(),map.getValue());
            }
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setUseCaches(false);
            // 设置请求方式（GET/POST）
            conn.setRequestMethod(requestMethod);
            conn.setRequestProperty("content-type", "application/json;charset=utf-8");
            //添加参数
            OutputStream outputStream = conn.getOutputStream();
            outputStream.write(paramJson.toString().getBytes("UTF-8"));
            outputStream.close();
            // 从输入流读取返回内容
            inputStream = conn.getInputStream();
            inputStreamReader = new InputStreamReader(inputStream, "utf-8");
            bufferedReader = new BufferedReader(inputStreamReader);
            String str = null;
            StringBuffer mess = new StringBuffer();
            while ((str = bufferedReader.readLine()) != null) {
                mess.append(str);
            }
            return JSONObject.parseObject(mess.toString());
        } catch (ConnectException ce) {
            System.out.println("连接超时：{}" + ce);
        } catch (Exception e) {
            System.out.println("https请求异常：{}" + e);
        }finally {
            try {
                // 释放资源
                bufferedReader.close();
                inputStreamReader.close();
                inputStream.close();
                conn.disconnect();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
        return null;
    }

    public static void main(String[] args) {
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("ottCode","0033d8e5e36745d38c7e0e73fcb4883c");
        JSONObject post = HttpsUtils.httpsRequest("https://xxx/api/authc/ottAuthor", "POST", jsonObject);
        JSONObject data = post.getJSONObject("data");
        System.out.println(post);
    }
}

返回结果：
