fine-uploader azure originator in request instead

Question

I am attempting to put blobs to azure storage and I believe I have the server side sas and azure CORS set up correctly. In my html I have var uploader = new qq.azure.FineUploader({ element: document.getElementById('fine-uploader'), debug: true, request: { endpoint: 'https://mystorage.blob.core.windows.net/mycontainer' }, signature: { endpoint: 'https://myserver/sas/' }, uploadSuccess: { endpoint: '/success' }, retry: { enableAuto: true }, deleteFile: { enabled: true }, cors: { expected: true, sendCredentials: true, },

In debug mode I see fine-uploader azure gets the sas correctly and then attempts to send the put request but instead of going to the azure endpoint as entered, it attempts to send it to the host as per this message.

Answer 1

Have you permitted PUT request in AllowedMethods while you set CORS rules?

I took your code with Fine Uploader 5.14.2 to upload an image file to Azure storage. It works fine on my site.
