Result: workedĢ) Connect through HTTPS (ie. I searched in google for some cloudapp examples and what I tested was the following:ġ) Connect through HTTP (ie. These two also offer a free subdomain:, but my question is: will I get HTTPS there too? and how? Which is the best practice to upload and download BIG files using a ASP.NET Core 2. I'm in need of upgrading to Azure Cloud Services or Azure Virtual Machines, because these have capabilities that Azure Websites don't. , and there, if they want to use my application, I redirect them to the subdomain at, using HTTPS. So, what I usually do is that people come by through some registered domain I have, eg. I don't have to worry about certificates because I use the subdomain that Azure gives me (in the example it would be xyz) ![]() Learning Web API? Get our eBook ASP.One great advantage of using Azure Websites is that I can get secure HTTP (HTTPS) without doing nothing: I simply type and it works. Using the file path the file is opened using the FileStream class and copied into the MemoryStream. The method further reads the server path for the file from the ServerFiles folder. The method check for the fileName is not null or empty. Lastly, we can delete the unnecessary getUsers() call from the initialization function.įinally, reference the list of URLs on the UI instead of the list of users and show it if it’s not empty: 0">īy comparing the files in the Images folder and the ones on the UI, we can see that all photos with the desired extension are shown and not only the ones that belonged to users: The DownloadFile () method accepts the file name which is requested to download. Since successful user creation triggers that method, we expect a refreshed list every time we add a new user and its photo. As expected, the DownloadFileCompleted event is fired whenever the file download has. The DownloadProgressChanged event is fired periodically as the download progresses and provides access to some useful properties such as BytesReceived and ProgressPercentage. The second call is in the returnToCreate() function. Additionally, two event handlers are wired up before the file download commences. Then, the first call of the function in the initialization function so that we load the list of photos when we access the home page for the first time. ().subscribe(data => this.photos = data) įirstly we add the photos property and inject the FileService inside the component. Changing the name to FileController and adding Route, its end-point has changed as well, therefore we have to update the code in the : (' formData, Since we’ve renamed the controller’s name in the API, we have to reflect those changes to the components on the client-side for everything to work as before. To begin with, let’s open our client-side project. That way, we can have a clearer view of what are the potential needs of a user and how to modify the API to fulfill those needs. This step was not necessary, but it will help us in knowing which end-point we actually want to execute from the client side.įor the time being, we will leave the download operation to return only a successful result and, in the meantime, start with the implementation of the client-side. But, what’s worth mentioning here is that we added a Route attribute to both of our endpoints. At the moment, the method will only return a successful result with a corresponding message: ")]ĭone. Given that we are focusing on a file download, the next step is to extend the controller with a new endpoint for download operation. Okay, well, that was easy, since we just renamed the controller. That way we are wrapping up the file handling logic into one controller that contains endpoints for every operation. Public class FileController : ControllerBase ![]() That said, the pictures that we upload during user creation will be the files that we are going to download after.Īs a first step, since we’re going to have both upload and download of files, we will go to our API and rename the UploadController to FileController: For the sake of simplicity, we will reuse the current implementation and extend it to implement file download. When we create a user, the uploaded picture becomes the profile picture. Server-side RefactoringĬurrently, we have an upload button in our form for creating a user. That way, we are improving readability and opening opportunities for extending the service in the future with more file handling operations. The adjustments will cover the addition of a service that contains all the desired logic for handling files in general. In this part, since we are adding new functionality, we will first adjust the current implementation. Now, let’s get on with the implementation.
