HttpURLConnection的post請求傳遞header參數和body參數的具體方法實現

@Test
public void testByTenantId() throws Exception {
    String tenantId="nhs7wd2c";

    String defURL = "http://bd.basdoc.com/rest/data/transfer";
    URL url = new URL(defURL);
    // 打開和URL之間的連接
    HttpURLConnection con = (HttpURLConnection)url.openConnection();
    con.setRequestMethod("POST");//請求post方式
    con.setUseCaches(false); // Post請求不能使用緩存
    con.setDoInput(true);// 設置是否從HttpURLConnection輸入，默認值爲 true
    con.setDoOutput(true);// 設置是否使用HttpURLConnection進行輸出，默認值爲 false
    
    //設置header內的參數 connection.setRequestProperty("健, "值");
    con.setRequestProperty("Content-Type", "application/json");
    con.setRequestProperty("isTree", "true");
    con.setRequestProperty("isLastPage", "true");

    //設置body內的參數，put到JSONObject中
    JSONObject param = new JSONObject();
    param.put("sysId", "diwork");
    param.put("tenantId", tenantId);

    // 建立實際的連接
    con.connect();

    // 得到請求的輸出流對象
    OutputStreamWriter writer = new OutputStreamWriter(con.getOutputStream(),"UTF-8");
    writer.write(param.toString());
    writer.flush();

    // 獲取服務端響應，通過輸入流來讀取URL的響應
    InputStream is = con.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
    StringBuffer sbf = new StringBuffer();
    String strRead = null;
    while ((strRead = reader.readLine()) != null) {
        sbf.append(strRead);
        sbf.append("\r\n");
    }
    reader.close();

    // 關閉連接
    con.disconnect();

    // 打印讀到的響應結果
    System.out.println("運行結束："+sbf.toString());

}
