Currently, I'm developing a mobile app using Nativescript and have integrated a WebView on the main page for logging in with Spotify. Post-login, I need to extract headers/query params from the WebView page. Is this achievable? If so, how can I go about it?
If you want to extract query parameters from the URL in your app, you can utilize the loadFinishedEvent by registering it and then checking for the specific URL that contains the desired parameters. This approach is particularly useful for scenarios like handling third party logins.
handleWebViewLoad(args) {
const webview: WebView = <WebView>args.object;
webview.on(WebView.loadFinishedEvent, (webargs: LoadEventData) => {
let message;
if (!webargs.error) {
if (webargs.url.toLowerCase().indexOf('spotity') > -1) {
// Extract and process query parameters here
}
message = 'WebView finished loading of ' + webargs.url;
} else {
message = 'Error loading ' + webargs.url + ': ' + webargs.error;
}
});
}
