CORS policy #33

Closed gbaccetta closed 2 years ago

gbaccetta commented 2 years ago

On flutter WEB I'm getting CORS policy error. Other requests I use in my app work properly. What am I doing wrong ?

I used the code from the sample and tried with www.google.com

Hey @gbaccetta this is how the web works, you will need your own proxy server to get around this, there is no other way.

Hi @demchenkoalex thank you for your answer. Yeah I was guessing as much. I was thinking of using firebase cloud functions that are already implemented in my apps, but I was not sure on a to change the request that is performed in the onPreviewDataFetched to achieve that. How can I override the method ? I wish to do it conditionnally using the kisweb flag

I've seen the cors proxy parameter in the sdk but that would not solve my problem with my current architecture. I think that for now I will just disable the preview on the web. I need to figure out how to go around it with firebase hosting and firebase cloud function. If the cloud functions fetch the preview data that should work properly but I need to rewrite the logic you used in your package. I'll let you know. If I achieve that, the code could maybe be shared for people in the same situation as me.

Did you have any luck with your work around?
