Swift 3 Azure Blob Storage Data (Image, Video) upl

问题:

I'm searching for an useful Swift 3 Azure Blob Storage example which I could use to upload some data(image, video). For now, I can insert records into my Mobile Service database and there I generate a SAS and I get it back to my iOS application. Now I need to know how to upload to Azure Blob Storage with help of that SAS. I successfully implemented the same for Android and it works, but somehow I have troubles to find any useful information for "SWIFT" and how to use the "SAS"!

Any code examples how to upload with SAS in Swift are much appreciated.

Regards,

Adam

For those who have the same problem as I had: This is a working example in Xcode 8 and Swift 3. You have to include the "Azure Storage Client Library" into your project.

//Upload to Azure Blob Storage with help of SAS
func uploadBlobSAS(container: String, sas: String, blockname: String, fromfile: String ){

// If using a SAS token, fill it in here.  If using Shared Key access, comment out the following line.
var containerURL = "https://yourblobstorage.blob.core.windows.net/\(container)\(sas)"  //here we have to append sas string: + sas
    print("containerURL with SAS: \(containerURL) ")
var container : AZSCloudBlobContainer
var error: NSError?

container = AZSCloudBlobContainer(url: NSURL(string: containerURL)! as URL, error: &error)
if ((error) != nil) {
print("Error in creating blob container object.  Error code = %ld, error domain = %@, error userinfo = %@", error!.code, error!.domain, error!.userInfo);
}
else {

    let blob = container.blockBlobReference(fromName: blockname)
    blob.uploadFromFile(withPath: fromfile, completionHandler: {(NSError) -> Void in
        NSLog("Ok, uploaded !")
    })
    }

}
