Ajax调用不能在android上工作，但在ios Cordova上工作很好

Ajax Call not working on android But working fine on ios Cordova

本文关键字：工作 但在 ios Cordova 很好 调用 android Ajax 不能      更新时间：2023-09-26

编辑:当然服务器端没问题，因为ajax在IOS和浏览器上做得很好=>允许跨源请求

我正在开发一个cordova移动应用程序。我为安卓和ios建立应用程序，但安卓应用程序不工作，不发送ajax请求。同时，Ios应用程序工作正常。这是我的config.xml .....

这是我的android android manifest 

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="10000" android:versionName="1.0.0" package="com.unitedway" xmlns:android="http://schemas.android.com/apk/res/android">
    <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
    <uses-permission android:name="android.permission.INTERNET" />
    <application android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name" android:supportsRtl="true">
        <activity android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale" android:label="@string/activity_name" android:launchMode="singleTop" android:name="MainActivity" android:theme="@android:style/Theme.DeviceDefault.NoActionBar" android:windowSoftInputMode="adjustResize">
            <intent-filter android:label="@string/launcher_name">
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="23" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
</manifest>

我的ajax请求代码返回状态404。

所以ajax请求在android上失败，但在ios和浏览器上工作良好。

我下载了你的项目，在我新创建的项目中替换了你的项目源代码，并将删除按钮单击函数的AJAX url调用替换为我的本地url，我成功地能够进行AJAX调用。事实上，我已经在成功回调中放置了一个警报，我也得到了警报。

所以无论如何它与编码无关。这可能是Android平台创建的问题，也可能是cordova白名单插件安装的问题。

已经在github中发布了工作代码库，还包括插件和Android平台，供您参考。请在进一步开发中使用相同的内容。

从版本5左右开始，cordova需要白名单插件。然后<access origin="*" />(或任何你选择的来源)应该工作。
