unsupported URL error

[dataexcess]

I'm trying to fetch some data of a simple rest api, but I always get a "unsupported URL error" even when using https://www.google.com as the URL...

here's my code:

void ScopeAudioProcessorEditor::tryRESTCall()
{
    RestRequest request;
    request.header ("Content-Type", "application/json");
    RestRequest::Response response = request.get ("https://jsonplaceholder.typicode.com/todos/1").execute();
    DBG ("REST API bodyAsString: " + response.bodyAsString);
}

This is the error:

Any ideas? Thnx

Which platform are you running this on?

[dataexcess]

macOS 12.3.1 XCode

What do you get when you call getBodyAsString or getURL on the Request object?

[dataexcess]

It gives the same error :(

[adamski]

I mean before you make the call. On the request object, not the response.

[dataexcess]

I could fix the issue by bypassing the url.getChildURL(endpoint) method call in the exectue() method. This seems to add a slash in front of my url...

    RestRequest::Response execute ()
    {
        auto urlRequest = URL(endpoint);
        //auto urlRequest = url.getChildURL (endpoint);
        bool hasFields = (fields.getProperties().size() > 0);
        if (hasFields)
        {

So now it works! thnx

[adamski]

Can you please post the results of getBodyAsString and getURL on the Request object? (before you made your change) - so I can understand the issue.

I suspect it's not expecting a full URL string with http at the front..

[dataexcess]

I called getBodyAsString on the Request object and it gives the same error. Before and after the execute method.

I think the problem is the prefix slash that Juce::URL adds in concatenatePaths() which is called by URL::getChildURL(), itself called by RestRequest::Response execute().

As you can see in your error : NSErrorFailingURLStringKey=/https://jsonplaceholder.typicode.com/todos/1

I don't really understand the logic of the code and why it works on Windows and not MacOS though.
