Ionic 3 Cordova ajax 调用在 Windows 10 (UWP) 上失败
我之前尝试过问这个，购买没有得到真正的答案，现在已经挣扎了一个多月.
I have attempted to ask this previously, buy got no real answers, and have now been struggling for over a month.
我只是无法让我的 ajax 调用在为 Windows 10 UWP 构建的 Ionic 3 Cordova 应用程序上工作.他们可以访问本地主机，但不能访问任何外部连接.
I just cannot get my ajax calls to work on an Ionic 3 Cordova application built for a Windows 10 UWP. They can access localhost, but not any outside connections.
该应用程序在 Android 和 iOS 上都能正常运行.
The application works fine on both Android and iOS.
我正在尝试在我的开发机器上进行本地测试.我使用证书(购买)签署应用程序，安装此证书，构建适用于 Windows 的应用程序，并且能够打开构建的 CordovaApp.Windows10_1.0.1.1_x86.appxupload，然后加倍点击嵌入的CordovaApp.Windows10_1.0.1.1_x86.appx文件进行安装，安装成功.安装表明该应用需要访问互联网.
I am trying to test this locally on my dev machine. I use a certificate (bought) to sign the application, install this certificate, build the application for Windows, and am able to open up the built CordovaApp.Windows10_1.0.1.1_x86.appxupload, and then double click the embedded CordovaApp.Windows10_1.0.1.1_x86.appx file to install, which completes successfully. The install indicates the app need internet access.
在 config.xml 中，我有以下标签，正如其他地方所建议的那样......
In the config.xml, I have the following tags, as suggested elsewhere...
<allow-navigation href="*" />
<access origin="*" />
但是，当我运行时，http.get 调用只返回 0 而没有其他信息.我可以在 Visual Studio 中运行，查看返回的错误对象，除了这个 0 返回之外，没有得到更多信息.
However, when I run, the http.get call just returns 0 with no other information. I can run in Visual Studio, and look at the returned error object, and get no further info, apart from this 0 return.
我已经运行了 fiddler，按照 here 的说明启用了 https 解密，但我在响应标头中看到的只是
I have run fiddler, enabled the https decryption as explained here, but all I see in the response header is
HTTP/1.0 200 Connection Established
FiddlerGateway: Direct
StartTime: 13:44:21.686
Connection: close
主视图中的结果实际上显示了 200，所以我认为这并没有向我展示任何真实的东西.
The result in the main view actually shows 200, so I don't think this is showing me anything real.
我完全不知所措.我没有其他地方可以搜索.我可能会错过什么?
I am at a complete loss. I have no where else to search. What could I be missing?
当我在此处旁加载应用程序时，我是否应该能够在 Windows 10 机器上使用外部 ajax?我还没有从商店尝试过，因为在我知道它有效之前我不想上传.
Should I be able to use external ajax on a Windows 10 machine, when I have sideloaded the application as here? I haven't tried from the store yet, as I don't want to upload until I know it works.
非常欢迎任何建议.肯定有人让 Ionic 3 应用程序访问外部 ajax 工作?
Any suggestions desperately welcomed. Surely someone has had an Ionic 3 application accessing external ajax working?
提前感谢您的帮助

如果我在同一台机器上运行应用程序，只使用 Ionic serve(所以它只是在浏览器中运行，而不是在 UWP 中托管)，ajax 调用也可以正常工作.
If I run the application on the same machine, just using Ionic serve (so it just runs in the browser rather than hosted in the UWP), the ajax calls also work fine.

我现在已经使用 Visual Studio 模板创建了一个 Cordova 应用程序，因此将所有其他框架排除在外.
I have now created a Cordova application using the Visual Studio template, so taking all other frameworks out of the equation.
我使用 vanilla JavaScript 来做我的休息调用...
I used vanilla JavaScript to do my rest call...
document.addEventListener('deviceready', callUrl, false);
function callUrl() {
console.log('callUrl');
var xhr = new XMLHttpRequest();
xhr.open('GET', 'https://myserveraddress.com/myapp/testroute');
xhr.send(null);
xhr.onreadystatechange = function () {
var DONE = 4; // readyState 4 means the request is done.
var OK = 200; // status 200 is a successful return.
if (xhr.readyState === DONE) {
if (xhr.status === OK)
console.log(xhr.responseText);
} else {
console.log('Error: ' + xhr.status);
}
}
};
我在调试器中运行它，甚至在这里我得到一个错误(状态代码为 0).
I run this in the debugger, and even here I get an error (status code of 0).
当我打开构建包并查看 cordova_plugins.js 文件时，我注意到的另一件事..
Another thing I noticed when I open up the build package and look at the cordova_plugins.js file..
我的 Ionic 应用具有以下...
My Ionic app has the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [
{
"id": "cordova-plugin-console.logger",
"file": "plugins/cordova-plugin-console/www/logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"cordova.logger"
]
},
{
"id": "cordova-plugin-console.console",
"file": "plugins/cordova-plugin-console/www/console-via-logger.js",
"pluginId": "cordova-plugin-console",
"clobbers": [
"console"
]
},
{
"id": "cordova-plugin-device.device",
"file": "plugins/cordova-plugin-device/www/device.js",
"pluginId": "cordova-plugin-device",
"clobbers": [
"device"
]
},
{
"id": "cordova-plugin-device.DeviceProxy",
"file": "plugins/cordova-plugin-device/src/windows/DeviceProxy.js",
"pluginId": "cordova-plugin-device",
"merges": [
""
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreen",
"file": "plugins/cordova-plugin-splashscreen/www/splashscreen.js",
"pluginId": "cordova-plugin-splashscreen",
"clobbers": [
"navigator.splashscreen"
]
},
{
"id": "cordova-plugin-splashscreen.SplashScreenProxy",
"file": "plugins/cordova-plugin-splashscreen/www/windows/SplashScreenProxy.js",
"pluginId": "cordova-plugin-splashscreen",
"runs": true
},
{
"id": "cordova-plugin-statusbar.statusbar",
"file": "plugins/cordova-plugin-statusbar/www/statusbar.js",
"pluginId": "cordova-plugin-statusbar",
"clobbers": [
"window.StatusBar"
]
},
{
"id": "cordova-plugin-statusbar.StatusBarProxy",
"file": "plugins/cordova-plugin-statusbar/src/windows/StatusBarProxy.js",
"pluginId": "cordova-plugin-statusbar",
"runs": true
},
{
"id": "ionic-plugin-keyboard.KeyboardProxy",
"file": "plugins/ionic-plugin-keyboard/src/windows/KeyboardProxy.js",
"pluginId": "ionic-plugin-keyboard",
"clobbers": [
"cordova.plugins.Keyboard"
],
"runs": true
}
];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-console": "1.0.5",
"cordova-plugin-device": "1.1.4",
"cordova-plugin-splashscreen": "4.0.3",
"cordova-plugin-statusbar": "2.2.2",
"cordova-plugin-whitelist": "1.3.1",
"ionic-plugin-keyboard": "2.2.1"
};
// BOTTOM OF METADATA
});
现在，我注意到 module.exports.metadata 中的每个插件在 module.exports 中也有一个条目，除了 cordova-plugin-whitelist！
Now, I notice every plugin in the module.exports.metadata also has an entry in the module.exports EXCEPT for cordova-plugin-whitelist!
如果我为在 VS 中创建的 Corvoda 应用程序打开相同的文件，我会看到以下内容...
If I open the same file for the Corvoda application created in VS, I see the following...
cordova.define('cordova/plugin_list', function(require, exports, module) {
module.exports = [];
module.exports.metadata =
// TOP OF METADATA
{
"cordova-plugin-whitelist": "1.2.2"
};
// BOTTOM OF METADATA
});
所以这对于白名单插件也没有其他作用
So this has nothing else for the whitelist plugin as well
这里会不会少了什么?这个白名单插件会不会安装不正确?
Could there be something missing here?? Could this white-list plugin not be installed correctly?
推荐答案
我有类似的情况，我的 ajax 调用在 TEST 中运行良好，但是当我转移到 PROD 时，它们会失败.
I had a similar situation where my ajax calls worked fine in TEST, but when I moved to PROD, they would fail.
最终在我试图访问的服务器上找到了一个缺少中间证书的答案.TEST 有证书，PROD 没有.
The answer was finally tracked down as a missing intermediary certificate on the server I was trying to access. TEST had the cert, PROD did not.
我希望这会有所帮助.
