Header parameters and Redirect

[glederrey]

Hi,

I encountered a problem using Swagger-UI.. (There's no problem while using the Web Browser or a client library generated by Codegen)

First, le me explain my call.. I call a function that will process some things and then will redirect to another page to send back a picture.. I attached a screenshot under it..

This is "working".. (Still have some issues with getting the picture, see #1848).. But the problem comes when I'm entering some headers parameters (here appId and appKey).. Swagger-UI does then a OPTIONS call before doing the POST one and don't do anything after that.. Normally, it should redirect as it is done before (without the headers parameters).. See the calls on the second screnshot..

Am I doing something wrong with the headers?? Or does anyone also encountered this problem??

Thank you

Have you added the headers to your CORS configuration?

Hi @webron,

Yes, I added them into the Access-Control-Allow-Headers.. That's what you meant by your question??

[webron]

Yes. Can you share the output of curl -I <url of api>?

[glederrey]

@webron I'll give you the output at 09-10am CET.. I don't have my computer for the work..

@webron Here is the output.. There's something weird because it says that the HEAD requests are not supported..

curl -I http://localhost:8080/nviso/api/cloud/v1/worker/nviso/photo/process/url
HTTP/1.1 405 Request method 'HEAD' not supported
Date: Tue, 02 Feb 2016 08:49:02 GMT

Yup, and it also doesn't show the CORS headers. So either they are not set, or the lack of HEAD support is going to make it more difficult to investigate.

[glederrey]

The things is that I'm using the Spring MVC server generated using Swagger Codegen.. So, do you know if there's a way to accept the HEAD requests??

[webron]

There are resources on the web on how to enable it, but that also depends on the Spring version and so on. I'd suggest doing a quick search on that.

[glederrey]

Okay, I will do that.. Thank you for your help..

add another cors extension to chrome... and enable it ... then it will work
