What is purpose of converting `Blob` to `File`? `File` inherits from `Blob` – guest271314 Mar 31 '17 at 05:26

I need to upload the files to the **ali-oss** server by it's _API_. But it doesn't support **`Blob`** but **`File`** from now on. – Dreaman Tu Mar 31 '17 at 07:00

I get a try to modify the **ali-oss**'s`API`.Just add a condition about the permission of `Blob`.What a surprise it works perfectly. – Dreaman Tu Jul 14 '17 at 02:29
