您好，我使用的是 cordova 11.0.0 版。
我發現在 www 目錄中的網頁如果有使用到 jquery 的 ajax post 呼叫都會失效。
例如以下程式碼 :

$.ajax({
        method: 'POST',
        url: 'http://192.168.1.3/plant_ajax/',
        headers: {'Content-Type': 'application/x-www-form-urlencoded'},
        dataType: "json",
        data: {RegID:1},
        retryCount: 3,
        success : function(response) {
               
		  console.log(response);

        },
	error : function(err){

		console.log(err);

	}
     });

我在 Android 的 ADV 模擬器中用 chrome 瀏覽器直接在網址列輸入 http://192.168.1.3/plant_ajax/ 這一段網址是有資料回應的。
但是在 cordova build android 建置好 android apk 之後，執行 cordova run android 在 ADV 中執行，卻都會發生
以上那一段程式碼無法連線到 http://192.168.1.3/plant_ajax/

似乎在 cordova 的 android 應用程式中無法使用 jquery 的 ajax 呼叫。

請問是否有解決方式?
感謝您的回覆。

猜測...會不會是要用 https

這邊有討論可以試試看 cors 、權限設定等等.. https://stackoverflow.com/questions/33024145/cordova-jquery-ajax-not-working

你的api action是post和get都行嗎?
直接打網址是用get...

我這兩天有查到最多的建議方式是說安裝 white-list 這一個插件，但是我在執行
cordova plugin add cordova-plugin-whitelist 這一個安裝指令的時候卻會出現以下類似警告訊息 :

我直接打開 cordova 專案下的 www 目錄的網頁，是可以正常透過 ajax 呼叫到 Server 端的。
目前可以確認的是，只要做：
(1) cordova build android
(2) cordova run android
(3) 在 Android Studio 的 ADV 手機模擬器裡執行，可以取得 ajax 的 error 事件的返回資料訊息如下 :
{
"readyState" : 0,
"status" : 0,
"statusText":"error"
}
