Cordova deeplinks - query parameter not detected from Universal Links - ios

Question

I am trying to add Universal Linking to a Cordova App using the ionic-plugin-deeplinks plugin.
According to this issue query parameters should work out of the box.
Universal Links for me work correctly except for links with query parameters.
Eg. https://my-site.com/?olddeeplinking=resetpassword&token=123
When I click on the link in an email the queryString field is always an empty string.
Am I missing something, do I need to enable the plugins to detect query params?
Here is the code that I'm using:
const deepLinkRoutes = {
'/user/login': {
action: 'showLogin',
resetUrl: '/',
},
'/user/forgot-password': {
action: 'showForgotPassword',
resetUrl: '/',
},
...
};
export const _getIonicRoutes = () => Object.keys(deepLinkRoutes)
.reduce((links, route) => {
links[route] = { target: '', parent: '' };
return links;
}, {});
export const handleUniversalLinks = () => {
const ionicRoutes = _getIonicRoutes();
const sy = obj => JSON.stringify(obj);
const matchFn = ({ $link, $route, $args }) => {
console.log('Successfully matched route', $link, $route, $args);
alert(`Successfully matched route: ${sy($link)}, ${sy($route)}, ${sy($args)}`);
return history.push($link.path);
};
const noMatchFn = ({ $link, $route, $args }) => {
console.log('NOT Successfully matched route', $link, $route, $args);
alert(`NOT Successfully matched route: ${sy($link)}, ${sy($route)}, ${sy($args)}`);
return history.push($link.path);
};
window.IonicDeeplink.route(ionicRoutes, matchFn, noMatchFn);
};
UPDATE:
It looks like the intent received on Android is always /user/login even though the Universal Link does not have it. What could be causing that?

Answer 1

A clue:
It looks like the deeplinks plugin is using window.location.href to detect the query parameter.
Since I am using cordova-plugin-ionic-webview the href is always the alias used for localhost of the Ionic engine serving the App contents, so the query parameters are never found.
Deeplinks plugin code:
https://github.com/ionic-team/ionic-plugin-deeplinks/blob/master/src/browser/DeeplinkProxy.js#L40
function locationToData(l) {
return {
url: l.href,
path: l.pathname,
host: l.hostname,
fragment: l.hash,
scheme: parseSchemeFromUrl(l.href),
queryString: parseQueryStringFromUrl(l.href)
}
}
onDeepLink: function(callback) {
// Try the first deeplink route
setTimeout(function() {
callback && callback(locationToData(window.location), {
keepCallback: true
});
})
// ...
}
This is the problem, not sure on the solution yet though.
