swift - 将图像上传到 Azure 存储

Question

当我将图像上传到 azure 存储时，我就这样做了

let storageAccount : AZSCloudStorageAccount;
            try! storageAccount = AZSCloudStorageAccount(fromConnectionString: config.getAzureConnection())

            let blobClient = storageAccount.getBlobClient()

            var container : AZSCloudBlobContainer = (blobClient.containerReference(fromName: config.getImagesContainer()))

            modelName = UIDevice.current.modelName
            let ticks = Date().timeIntervalSince1970 * 1000
            let imageName: String = "\(modelName)-\(ticks).png"

            let blob: AZSCloudBlockBlob = container.blockBlobReference(fromName: imageName)
            let imageData = UIImagePNGRepresentation(pickedImage)

            blob.upload(from: imageData!, completionHandler:{(NSError) -> Void in

            })

但在 azure 存储中，内容类型保存为 application/octet-stream 而不是 image/PNG。上传图片时如何更改内容类型？

Answer 1

blob 对象应该有一个名为“Properties”的属性。应该是这样的；

blob.Properties.ContentType = "image/png";
