我正在使用Cordova 9.0.1：
[luis@luis myapp]$ cordova -v
9.0.0 ([email protected])
我无法解决此问题。每当我尝试使用简单的jQuery Post请求从Android应用程序登录到我们的服务器时，都会输入fail（）方法。该请求未登录到Apache访问日志中，因此它永远不会到达服务器。
但是，如果我运行cordova并从浏览器尝试，则登录成功。
这是我的config.xml文件：

您可以检查，它具有用于跨域访问的标签：
<access origin="*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<allow-intent href="tel:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />
我甚至将此标签添加到应用程序index.html的入口点：
<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; connect-src *">
我将其视为其他地方的解决方案，但仍然无法正常工作。
这是一段失败的代码。应用程序控制台中未显示任何错误消息（我正在将设备插入计算机后对其进行测试，以便可以检查控制台）：
console.log('Post to ' + url + ' user:' + data.user + ' password:' + data.password); // both the URL and the data are correct
$.post(url, data, function(res) {
// This code is not reached
if (res.id !== undefined && res.token) {
console.log('Login OK');
// store user data...
return;
}
if (res.error) {
// alert the validation error
return;
}
alert('Unexpected server error');
}).fail(function(jqXHR, textStatus, errorThrown) {
console.log('Login error: ' + textStatus + ' ' + errorThrown);
// show error in login form...
});
控制台中显示的错误是：登录错误：错误 未找到
您能帮我吗？我被困住了，什么都没想到，我已经做了发现的所有事情。
我找到了解决方法：
从Cordova 9，API级别28开始，所有具有Android 9或更高版本的设备都被迫发出https请求而不是http，除非在异常配置中指定，否则它将始终失败，如此处所述：
