Question

我经常需要在我的应用中显示一些加载行为，并且我想在完成工作后将其解雇 - 无论工作成果是成功还是错误 。因此，我最终得到了这样的代码：

addDisposable(router.launchHomepage()                            
    .compose(loadingView.show()))
    .subscribe(
        { loadingView.dismiss() },
        { loadingView.dismiss() }
    )
)

有没有办法在单个方法中解除加载视图？与onComplete()类似，但无论结果是成功还是错误都会调用？

创建课程

public string GetBlobSasUri(string containerName, string blobName, string connectionstring)
{
    CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionstring);
    CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
    var container = blobClient.GetContainerReference(containerName);
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(blobName);

    //Set the expiry time and permissions for the blob.
    //In this case no start time is specified, so the shared access signature becomes valid immediately.
    SharedAccessBlobPolicy sasConstraints = new SharedAccessBlobPolicy();
    sasConstraints.SharedAccessExpiryTime = DateTime.UtcNow.AddMinutes(10);
    sasConstraints.Permissions = SharedAccessBlobPermissions.Read;

    //Generate the shared access signature on the blob, setting the constraints directly on the signature.
    string sasContainerToken = blockBlob.GetSharedAccessSignature(sasConstraints);

    //Return the URI string for the blob, including the SAS token.
    return blockBlob.Uri + sasContainerToken;
}

并使用

public ActionResult  FileDownload()
{
    string blobURL = GetBlobSasUri("blob name","container name", "connection string");
    return Redirect(blobURL);
}

是否有一个方法在Observable的onSuccess（）或onError（）之后执行？
