问题
I was validating my manifest on this page with this manifest URL of my app hosted on GitHub:
https://raw.githubusercontent.com/my_username/my_application/master/manifest.webapp
This is the error I got:
Manifests must be served with the HTTP header "
Content-Type: application/x-web-app-manifest+json". See https://developer.mozilla.org/docs/Web/Apps/Manifest#Serving_manifests for more information.
So I checked that link mentioned in the error and it says:
If you serve your manifest file from GitHub Pages, GitHub will serve it with the Content-Type header of
application/x-web-app-manifest+json.
Assuming that I need to create a GitHub page for my app, I created it and passed on that link to validate. Then I got 2 errors:
- JSON Parse Error
- Manifests must be served with the HTTP header "
Content-Type: application/x-web-app-manifest+json". See https://developer.mozilla.org/docs/Web/Apps/Manifest#Serving_manifests for more information.
My JSON is valid, I had it checked on jsLint. Also, I am assuming that the GitHub page is passing on the required header when I am giving the respective URL. Still it's failing.
How do I fix this?
回答1:
You are not serving this manifest over GitHub pages, but as 'Raw' content. All content on raw.githubusercontent.com is served as text/plain.
Use real Github pages to make this work.
