如何在Azure存储iOS SDK中取消Azure Blob上传/下载请求

问题描述

我可以使用Azure Storage iOS SDK将图像上传到Azure blob /从Azure blob下载图像，它运行良好，但是现在我想取消正在进行的上传/下载请求。

我找不到取消这些请求的任何方法，有什么办法吗？

上传请求

NSError *accountCreationError;
// Create a storage account object from a connection string.
AZSCloudStorageAccount *account = [AZSCloudStorageAccount accountFromConnectionString:@"DefaultEndpointsProtocol=https;AccountName=your_account_name_here;AccountKey=your_account_key_here" error:&accountCreationError];

if(accountCreationError){
    NSLog(@"Error in creating account.");
}

// Create a blob service client object.
AZSCloudBlobClient *blobClient = [account getBlobClient];

// Create a local container object.
AZSCloudBlobContainer *blobContainer = [blobClient containerReferenceFromName:@"containerpublic"];

// Create a local blob object
AZSCloudBlockBlob *blockBlob = [blobContainer blockBlobReferenceFromName:@"name.jpeg"];
blockBlob.properties.contentType = @"image/jpeg";
NSData *data = UIImageJPEGRepresentation(image,0.7);
// Upload blob
[blockBlob uploadFromData:data completionHandler:^(NSError * _Nullable error) {
    if (error) {
        NSLog(@"Error in uploading blob");
    }
}];

下载请求

    NSError *accountCreationError;
    // Create a storage account object from a connection string.
    AZSCloudStorageAccount *account = [AZSCloudStorageAccount accountFromConnectionString:@"DefaultEndpointsProtocol=https;AccountName=your_account_name_here;AccountKey=your_account_key_here" error:&accountCreationError];

    if(accountCreationError){
        NSLog(@"Error in creating account.");
    }

    // Create a blob service client object.
    AZSCloudBlobClient *blobClient = [account getBlobClient];

    // Create a local container object.
    AZSCloudBlobContainer *blobContainer = [blobClient containerReferenceFromName:@"containerpublic"];

    // Create a local blob object
    AZSCloudBlockBlob *blockBlob = [blobContainer blockBlobReferenceFromName:@"name.jpeg"];
    blockBlob.properties.contentType = @"image/jpeg";

    // Download blob
    [blockBlob downloadToDataWithCompletionHandler:^(NSError * _Nullable error,NSData * _Nullable imageData) {
          if (error) {
            NSLog(@"Error in downloading blob");
        }
    }];
