java后端調(diào)用第三方接口(往header和body中的參數(shù)傳參)

最近被分配干大華攝像頭，需要調(diào)用第三方接口。

java如何調(diào)用對(duì)方http接口（header和body中的參數(shù)傳參）

之前調(diào)用的釘釘?shù)谌浇涌诙际瞧胀▊鲄ⅲ芎?jiǎn)單。

這次是往請(qǐng)求頭和請(qǐng)求體里面?zhèn)鲄?/h3>

//從配置文件中讀取路徑  可以寫死     "http://。。。。。。。"
        String serverURL = "https://www.cloud-dahua/liveList";
        StringBuffer sbf = new StringBuffer();
        String strRead = null;
        URL url = new URL(serverURL);
        HttpURLConnection connection = (HttpURLConnection)url.openConnection();
        connection.setRequestMethod("POST");//請(qǐng)求post方式
        connection.setDoInput(true);
        connection.setDoOutput(true);
        //header內(nèi)的的參數(shù)在這里set。||connection.setRequestProperty("健, "值");
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setRequestProperty("Authorization", "Bearer 59e0-9fcc-c3faea0e2a6c");
        connection.connect();
        OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(),"UTF-8");
        //body參數(shù)在這里put到JSONObject中
        JSONObject parm = new JSONObject();
        parm.put("pageNum", 1);
        parm.put("pageSize", 2);
        parm.put("storeId", 001);
        writer.write(parm.toString());
        writer.flush();
        InputStream is = connection.getInputStream();
        BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
        while ((strRead = reader.readLine()) != null) {
            sbf.append(strRead);
            //sbf.append("\r\n");
        }
        reader.close();
        connection.disconnect();
        String results = sbf.toString();
