Communication with external API (that runs over http) using POST method

Oles_Lototsiy · January 10, 2023, 11:14am

Hello community.
There is next task: I have Backendless UI with one input element. When I change value in that field, next script executes:

variable data_write:

So, when I change input field value, POST request with value writing to my API server should be executed.
Server works correctly and URL, header, body parameters are correct too - I checked it with other software. But it runs over http (I created it for testing purposes firstly). .

When I change value of input field via Backendless UI, in browser Devtool I see next message:

I suppose Backendless does not accept connection with server that runs over http.

Any ideas how to solve this issue? If reason is with API server that runs over http - how to solve that?

I changed http:// to https:// and it does not works:

servers runs over http.

browsers do not allow to run requests over HTTP if the page is opened over HTTPS

so solve this you’ve got 3 options:

run your UIBuilder app over HTTP
run your extra server over HTTPS
create an API Service as a proxy to call your extra server over HTTP

run your UIBuilder app over HTTP - you mean Backendless Viewer Android/iOs app? If yes, where can I find option to change http/https connection types? Or I should do it somewhere in settings menu of Backendless account?

as far as I know Backendless Viewer Android/iOs always runs over HTTPS

Ok, what about PC browser? When I click PREVIEW button in UI builder new page with UI is opened (of course via https). I cannot change https to http there. What should I do to open this page over http (preferably by default)? Are there some related settings in Backendless account?

no, there is no option to switch to http

it seems like this is the only option for you

create an API Service as a proxy to call your extra server over HTTP
