各位童鞋大家好，向來簡單粗暴的鐵柱兄給大家來玩一手套娃模式來組Json資料，不說別的，無腦套。

　　當然，這一手比較適合臨場用一下，若長期用的話建議搞一套適用的框架，只管set就好了。話不多說開始上課。

　　套娃模式這個顧名思義啊，就是一層一層的往裡面套就好了，特舒服。先上一手程式碼：

傳送https請求的程式碼我是隨便搜的，這一套如果對你適用的話就直接複製過去了，套娃這套程式碼對發什麼請求都無所謂，只要對方要求的是json格式的。

	                if (resEntity != null) {
	                    result = EntityUtils.toString(resEntity, charset);
	                }
	            }
	        } catch (Exception ex) {

	 }
	 private static String url = "https://xx.xx.xx.xxx:xxxx/xxxx/xxxx";//填寫需要傳送請求的地址 https後面跟ip跟埠跟地址
	 private static String charset = "utf-8";

	 public static void main(String[] args) {
		   
	    /**
	     * new幾個JSONObject出來作為套筒
	     * 需要幾層就new幾個
	     */
	        JSONObject json=new  JSONObject();//最大的套筒
	    	JSONObject json1=new JSONObject();
	    	JSONObject json2=new JSONObject();
	    	//json1、json2作為第二層套筒 這些資料放自己需要的即可
	    	json1.put("txnCode", "GWS00004");
	    	json1.put("reqDate", "20201102");
	    	json1.put("reqTime", "101532");
	    	json1.put("channelId", "  stockapp");
	    	json1.put("traceNo", "9e4124f5b1c145c18b698fb7d5628002");
	    	json.put("header", json1);
	    	json2.put("ciNo", "8000001397");
	    	json.put("body",json2 );
	        String encryptStr = json.toString();
	        System.out.println("encryptStr：" + encryptStr);
	        String httpOrgCreateTestRtn = doPost(url, encryptStr, charset);//丟去傳送剛組的資料
	        System.out.println("result:" + httpOrgCreateTestRtn);//返回資料
	}
}

　　組起來其實是很容易的，有了思路隨便套，隨便多少層，隨意套。

encryptStr：{"header":{"txnCode":"GWS00004","reqDate":"20201102","traceNo":"9e4124f5b1c145c18b698fb7d5628002","reqTime":"101532","channelId":"  stockapp"},"body":{"ciNo":"8000001397"}}
result:{"header":{"txnCode":"GWS00004","resDate":"20201102","resTime":"051127","retCode":"DD6010","errMsg":"DD6010","traceNo":""}}

　　這套方法也適用Map，解釋啥的我一如既往的丟註釋裡了，有不明白的地方歡迎提問。謝謝
