Any request to the real API results in a 404 about api-designer

Hi @igorkosta, you are pretty much describing CORS issues in your API.

In case you are not aware of what CORS is:

Due to security constraints, web browsers (and web services) do not allow web applications to reach a web services unless they are hosted in the same domain. To allow Cross Origin HTTP requests, web browsers make a special request (that OPTIONS request is called "preflight request") to the Web service, using some custom HTTP headers to find out if it is allowed to make the actual web service call, based on the server's response, the web browser then makes the actual HTTP request. This is all handled by the web browser automatically, so there's nothing we can do in the API-designer.

Solutions:

• host the API-designer in the same domain as the actual REST API you intend to call
• enable CORS in your REST API for the domain your API-designer is hosted (http://enable-cors.org/)
• host a service proxy in the same server you host the API-designer, this proxy would relay the API calls generated in the API-designer and relay them to your live REST service.

Hi @dmartinezg,
thank you very much for such a detailed answer!

Hi @dmartinezg,
do you know, how can we "teach" API-Designer to use the proxy hosted on the same server as the API-Designer itself. The only thing we can configure is the baseUri in our .raml document.

Thank you for your help in advance!
