chrome devtools 扩展：Windows 上的 CORS 问题

Question

I'm building a chrome extension, where I add a panel in the devtools, from where I need to perform some ajax calls.

From what I read , I have to add my domain in the manifest.json permissions:

{
  ...
  "permissions": ["https://example.com/"]
}

And from within my devtools panel, I'm now able to perform api calls to the server.

Except that on chrome-windows, nothing works.

From what I could observe:

• osX, linux: as long as the domain is authorized, everything works fine
• windows: a pre-flight request is sent although the domain should be authorized. It then fails, and everything is blocked

Is there something I'm doing wrong here ?

Thanks,

Answer 1

Ok, without changing anything the extension seems to behave as expected now.

My guess is that there was some bug on chrome/windows that have been fixed since. Closing the question.

If you're having trouble with regard to CORS in chrome extension, check the Cross-Origin XMLHttpRequest guide. There's a Requesting cross-origin permissions which details how you can implement cross-origin permissions.

There's also a handy chrome extension app called Allow-Control-Allow-Origin which might help when testing xhr requests.
