I would like to access the websocket data of an iframe inside a webpage using puppeteer.
To access websocket data of the main page I use:
const cdp = await page.target().createCDPSession();
This is how I locate the iframe:
const iframe = await page.frames().find(frame => frame.url().includes('https://url-of-iframe.com'));
How can I access the websocket data of the iframe? Preferably without having to open the iframe content as a new page as I need to have access to the main page data as well.

I am doing an application where when the user click on social login it opens a new window. Let's say my application is running on Chrome and my default browser was set to Edge; the URL is getting opened in Edge. After successful token generation it is redirecting to the application without closing the browser window/tab.
I am using azure AD authentication as follows
IPublicClientApplication app = PublicClientApplicationBuilder
.Create(azMapping.ClientId)
.WithAuthority(authority)
.WithRedirectUri("http://localhost:44342/Default.aspx")
.Build();
result = app.AcquireTokenInteractive(scopes)
.WithSystemWebViewOptions(new SystemWebViewOptions())
.ExecuteAsync(CancellationToken.None)
.GetAwaiter().GetResult();
The authority URL opens in the default browser. Is there a way to open the URL on the application running or can we close once we got back the response?
You can use the destinationpageurl property
The DestinationPageUrl property specifies the page that is displayed when a login attempt is successful.
Or
You can use the JavaScript to achieve this window.location.href returns the href (URL) of the current page
Response.Redirect should work if you just want to navigate to the same window page.

You can have a look to how to handle it see here
Set-up:
I have a web component (Angular 10) being used in an Angular 10 Application. The web component makes an Httpclient call to a web API to get some data to populate a menu dropdown. The web component was made using the standard methods to make a web component using Angular 10.
The web component is loaded through a script in the main client application. This is from the angular.json file for the parent application.
1."scripts":
[
"projects/web-component-test/src/assets/plugin.bundle.js"
]
and all works fine except we get a 401 error (unauthorized) since the end point requires the user to be logged in. By working fine, there are other controls that display as required just the the dropdown list, which gets it data from the API call does not get populated.
The flow:
User goes to website and then is prompted to log in (using keycloak Auth).
Application loads fine, except for the 401 error when the web component tries to load the menu items.
Http calls from the parent app work fine; the jwt token is added to the header for the call to the protected API. Calls from the child web component do not have the jwt token in the header, and thus fail with a 401 error.
httpinterceptor: we have an httpinterecptor on the main client application (the parent of the web control). Http calls that are made from the main app are routed through the interceptor where the token is attached to the header if needed.
Calls made from the child Web Component DO NOT hit the interceptor in the parent app?
Question:
How do I make call from the child web component route through the http interceptor in the parent so the token can be added.
Things I have tried:
I can get the web component to work fine if I do this:
When the parent loads I store the token in local storage
using an http interceptor on the web component, retrieve the token from local storage and use it.
** works, but I DO NOT want to store a secure token in local storage.
Pass the token in an attribute on the child component when the parent loads the child component
** again, I can get it to work, but not very secure.
A web component is an independent piece of code from your main codebase, so when you hit a request from the web component, your main app won't be able to catch those requests in the interceptor.
For me, one thing it worked was creating different Custom Events per every request:
doGetRequest
doPostRequest
doPutRequest
doDeleteRequest
Let me quickly guide you through one example of these events.
From the main app, I'm listening if any of these events are triggered:
this.popupEl.addEventListener('doPostRequest', (info: HTMLElementEventMap | any) => {
this.performHttpRequest(info.detail);
});
Notice that all the info sent from your web component, can be found in the property 'detail' your main app receives.
From the web component, I execute the following:
this.doPostRequest.emit({
url: 'the URL to hit',
endpointParams: {
user: 'my user',
password: '******',
}
});
Note: You can change the structure of the params to sent. It's totally up to you.
This will trigger the execution of the API in the main app, and as the request was executed from the main app, your interceptor will do its work and add whatever JWT you have there. Once the main app receives the response, you will need to set a new property in your web component to pass the response to it. Something like this:
this.popupEl.apiResponse = {
webComponentInfo: { ...infoReceivedFromYourWebComponent },
apiDetails: { ...ResponseFromYourBackend}
};
Finally, in your web component, add a new input that listen for the apiResponse attribute:
#Input()
set apiResponse(apiResponse: RequestParams) {
if (apiResponse.webComponentInfo.url === 'the URL to hit') {
// Do what you want in your web component, as you know exactly which URL just got executed.
}
}
This way, you let your main app continue doing its work with your interceptor and the web component won't need to handle the JWT or actually perform the requests.
One thing you may want to consider is not allowing the Delete request from your web component unless you and only you have full control over the web component. You wouldn't want anything that can perform a successful DELETE request to a very important API.
Hope this helps.
I am developing a Blazor Webassembly application. Based on the page the user came from, I should show different content. For example, the app should show Content A when the user came from Facebook and Content B otherwise. How can this feature achieved?
I red that one could do this by checking the referrer property of the request header, but I don't know how to access the http request on a razor page.
You can use javascript for this.
1) Create a javascript file on your blazor project (the front-end) with the following content:
function getReferrer() {
return document.referrer;
}
2) Add the previous file to your index.html file:
<script src="JavaScript.js"></script>
3) Consume the function using the IJSRuntime service:
var referrer = await js.InvokeAsync<string>("getReferrer");
This should get you the referrer.
Im trying to use the sdk without a canvas application, so have followed steps 1-7 in the quickstart guide up to adding the facebookSettings property in the Web.config.
I have added an image to my page and an onclick event that contains the below code. but when I click the button, it just takes me to the home page (CancelUrlPath).
Changing the Authorizer to a CanvasAuthorizer results in FB loading the login screen, but I get an error 404 not found on the call (even after inserting the handlers into the config)..
fbApp = new FacebookApp();
authorizer = new Authorizer(fbApp) {Perms = requiredAppPermissions};
authorizer.ReturnUrlPath = "http://localhost/User/UserRegister.aspx";
authorizer.CancelUrlPath = "http://localhost/";
if (authorizer.Authorize(this.Context))
{
Response.Write("hello");//never gets here
}
Can anyone help please?
Note: I've set the canvas and site url to http://localhost/ on the FB app settings.
If you are just building a simple connect website you really don't want to use the server side authentication tools to authenticate your user. Just use the Javascript SDK to athenticate the user. If you need to do anything on the server side, the FacebookApp class will automatically pick up the user's session from the values stored in the cookies.
See the Facebook documentation for more details: http://developers.facebook.com/docs/guides/web/#registration
We have a Flex client and a server that is using the Spring/Blazeds project.
After the user logs in and is authenticated, the spring security layer sends a redirect to a new URL which is where our main application is located.
However, within the flex client, I'm currently using HTTPService for the initial request and I get the redirected page sent back to me in its entirety.
How can I just get the URL so that I can use navigatetourl to get where the app to go where it needs to?
Any help would greatly be appreciated. Thanks!
One solution would be to include a token inside a comment block on the returned page, for instance:
<!-- redirectPage="http://localhost/new-location" -->
then check for it's presence inside the HTTPService result handler. The token's value could then be used in your call to navigateToURL.
Another solution would be to examine the HTTP response headers and extract the value of the "Location" header using ActionScript. Consider using the AS3 HTTP Client lib.
From the examples page http://code.google.com/p/as3httpclientlib/wiki/Examples To determine the 'Location' header from the response:
var client:HttpClient = new HttpClient();
var uri:URI = new URI("http://localhost/j_security_check");
client.listener.onStatus = function(event:HttpStatusEvent):void {
var response:HttpResponse = event.response;
// Headers are case insensitive
var redirectLocation:String = response.header.getValue("Location");
// call navigateToURL with redirectLocation
// ...
};
// include username and password in the request
client.post(uri);
NOTE: AS3 HTTP Client depends on AS3 Core and AS3 Crypto libs.
You can also simply use the URLLoader class, no need for external code. One of the events it dispatches is HTTPStatusEvent.HTTP_RESPONSE_STATUS. Just plug into that and retrieve the redirected url:
urlLoader.addEventListener(HTTPStatusEvent.HTTP_RESPONSE_STATUS, onHTTPResponseStatus);
private function onHTTPResponseStatus(event:HTTPStatusEvent):void
{
var responseURL:String = event.responseURL;
}
I am (successfully) using this code right now, so if it doesn't work for some reason, let me know.
