问题 I cannot download an image blob in my JavaScript client using the Google Photos REST API. My XMLHttpRequest is getting a 404. I have a valid OAuth token and can list the mediaItems. The token was generated using an offline access code. The same XMLHttpRequest download method works with both GDrive and Dropbox, allowing me to show download progress. I've tried using the "=d" and "=w123h345-c" baseUrl suffixes (where 123 and 345 are the respective width and height of the image). I've tried

The details are: Site: https://a.a.com API: https://b.a.com --API response headers Access-Control-Allow-Credentials: true Access-Control-Allow-Origin: https://a.a.com --cookie previously set with Set-Cookie: value

问题 I want to administratively prevent a whole class of XSS attacks by not allowing anything on my page to send XHR/XMLHttpRequest (or other?) requests to other domains than the domain hosting the page. Is that possible? I thought I could do that with Cross-Origin Resource Sharing (CORS), but it seems I was wrong. If a page hosted on domain-a.com tries to make an XHR request to domain-b.com, CORS can be used on domain-b.com pages to control whether or not that is allowed. So if something on the

问题 I have a react microservice (via nginx) deployed onto google cloud run with its environment variable for the backend set to another google cloud run instance that's running gunicorn which is serving the backend.

问题 I'm having issue getting my ionic app to POST to my API. On my api I have set the following headers: header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Headers: Content-Type"); header("Access-Control-Allow-Methods: GET,PUT,POST,DELETE,OPTIONS"); When posting from Postman or the actual website, everything functions as expected and I see these headers come back but once I open up my app and send a request, it no longer works.
