Error 1101: Could not get response with specified URL

[rob2]

I have a problem with calling the GET url function (there was no problem on LK 3.0), so I created an app using MIT AppInventor - as before on LK 3.0.

After calling the function, the following message will appear:
Error 1101: Could not get response with specified URL: https://user:password@ip-address:port/outs.cgi?out4=1

What could be the problem, because I'm running out of ideas?

Does the same url work in your computer browser ?

Are you following this guide? :

App Inventor Tutorials and Examples: File Download | Pura Vida Apps

[rob2]

Yes, I am following this tutorial. It works from the browser, but if you additionally click on the acceptance / negation of the certificate - I suspect that it blocks the option via MITTappinvertory, because there is no way to save the option to additionally confirm the certificate ...

[rob2]

EDIT:
So I ran tests - it's exactly as I wrote.
If you remove https in Lankontroler - in Settings and management > network - then there is no problem.
If the https service is enabled - then the GET command is not executed - because the ssl error message is reported (of course, because it is not registered) and the GET command does not work. Question: is it possible to bypass the quality of the question about unregistered ssl certificate in Appinwertory?

[TIMAI2]

Check ignore SSL in the designer?

[rob2]

Yes, there is the IgnoreSslErrors option, but for the component: WebViewer - and I'm not talking about opening a web page (WebViewer) but about calling the url get function (Web component) and there is no ssl ignore...

[TIMAI2]

What are the API instructions? Are you certain the data can be returned without using a web page interface? Have you tried with a webview?

From your images of blocks, your url looks wrong, given you are supplying the access credentials in the web header. Should be something like:
https://ip_address:port/outs.cgi?out4=1

[rob2]

I tried it anyway - unfortunately the error is more serious - I know how it should be.

HTTP OK, HTTPS with 1101 error

Unfortunately support for self-signed SSL certificates in the Web component is still an open issue:

Should we have an "ignoreSSLError" flag on the web component?

It is and still is a problem, because there is a question about the ssl certificate that needs to be confirmed per session.

But, when the connection is without ssl - just http - works great, only that the credentials fly in plain text ...

[TIMAI2]

Can you get the data back in a webview, if so you could run a javascript to scrape the data into your app that way ?

[rob2]

I haven't done it and have no idea how to do it...

[TIMAI2]

@TIMAI2

Can you get the data back in a webview

Try this first

[rob2]

ok After entering the url get command in the web browser, this appears first (ssl confirmation)

After confirmation - it actually gets to the Lankotroler and the GET function is called - the relay in the Lankotroler changes its state:

View in panel Lankontorer:

Now try this:

Web component javascript error (please turn javascript on)

Hello, I've got a web component in my app which was go to a url and get its content for me. It was working yesterday and I did not change anything but now it is not working. It goes to url, response code is 200 but in content I saw: "Please turn JavaScript on and reload the page" How can I turn on js in web component? Thanks in advance. Addition edit: how to send proper user agent data to website if its possible? so website can not understand that I am connecting with web component and wi…

You should be able to return the rendered page content to your app (webviewstring) and extract the data from there.

[TIMAI2]

This works for me based on the id of the xml element in my webview:

window.AppInventor.setWebViewString(document.getElementById('webkit-xml-viewer-source-xml').innerHTML)

The webviewer can be made not visible, if required.

[rob2]

did you test it on https?

unfortunately it doesn't work

**
Error 1101:Unable to get a response with the specified URL: https://ip-number/outs.cgi?out3=1
**

[TIMAI2]

Where has your port number gone ?

Remove check connection, use the webviewer error event block instead if connecting to the url fails

[rob2]

I threw out the port and did directly. And yes:
After launching the application, the following message appeared:

after clicking on the button - like this:

The blocks look like this:

[rob2]

BUT - when I remove the service over https in Lankontroler - and communication is only over http - everything works.
Screen - app:

Blocks:

So - clearly the problem is that after starting communication over https - a message about accepting the ssl certificate not-signed appears, and the application is unable to pass it - unless there is a possibility, the application first (in the background) opened this page , accepted the not-signed certificate and then performed the GET command - but is it possible?

[rob2]

Ok, I did it and it worked

• so far:

1. Webviewer establishes ssl communication (ip address only) + added component: WebViewer - ignoresslErrors

2. after pressing the Button - the GET url function is called

I wonder if this is the correct solution?

and

I would have to add and test the per-user authorization options...

code:

[rob2]

IT WORKED
with authorization
