Problem Description

If you use OSS-accelerated domain names of a bucket to access an object whose MIME type (the Content-Type response header) is application/vnd.android.package-archive or application/iphone in the bucket, the HTTP status code 400 is returned.

Causes

To enhance data security, if you access objects whose MIME type (the Content-Type response header) is application/vnd.android.package-archive or application/iphone in buckets for which the transfer acceleration feature is enabled on or after 00:00:00 (UTC+8) on August 5, 2024 anonymously or by using signed object URLs that contain OSS-accelerated domain names (format: bucketname.oss-accelerate.aliyuncs.com or bucketname.oss-accelerate-overseas.aliyuncs.com), the requests are denied. The HTTP status code 400 and the ApkDownloadForbidden error code are returned.

Examples

When you use an OSS-accelerated domain name of a bucket to access objects whose MIME type (the Content-Type response header) is application/vnd.android.package-archive in the bucket, the following output is returned:

curl -v http://test-demo.oss-accelerate.aliyuncs.com/test-file

Solutions

Use a custom domain name to access the preceding objects. In this case, requests are not denied. For more information, see Access OSS through a custom domain name.
