Firebase Depolama Alanı ve Erişim Denetimi-İzin-Menşei

Question

Firewall'lardan bir XMLHttpRequest aracılığıyla dosyaları karşıdan yüklemeyi deniyorum, ancak Access-Control-Allow-Origin kaynağında ayarlanmadı, bu yüzden mümkün değil. Bu üstbilgiyi depolama sunucusuna yerleştirmenin herhangi bir yolu var mı?

(let [xhr (js/XMLHttpRequest.)] 
    (.open xhr "GET" url) 
    (aset xhr "responseType" "arraybuffer") 
    (aset xhr "onload" #(js/console.log "bin" (.-response xhr))) 
    (.send xhr))) 

Krom hata iletisi: Bu post on the firebase-talk group/list itibaren

XMLHttpRequest cannot load https://firebasestorage.googleapis.com/[EDITED] No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin ' http://localhost:3449 ' is therefore not allowed access.

The easiest way to configure your data for CORS is with the gsutil command line tool. The installation instructions for gsutil are available at https://cloud.google.com/storage/docs/gsutil_install . Once you've installed gsutil and authenticated with it, you can use it to configure CORS.

For example, if you just want to allow object downloads from your custom domain, put this data in a file named cors.json (replacing "https://example.com" with your domain):

[ 
    { 
    "origin": ["https://example.com"], 
    "method": ["GET"], 
    "maxAgeSeconds": 3600 
    } 
] 

Then, run this command (replacing "exampleproject.appspot.com" with the name of your bucket):

gsutil cors set cors.json gs://exampleproject.appspot.com 

and you should be set.

If you need a more complicated CORS configuration, check out the docs at https://cloud.google.com/storage/docs/cross-origin#Configuring-CORS-on-a-Bucket .
